Philips Hue vs Philips Wake Up Light

Philips leads many areas of lighting, and I appreciate a business that knows to specialise and do well in their chosen area.

I have been using a Philips 3520 Wake Up Light for over a year now. I find it very gently wakes me up, especially in winter, and suits my rhythms well. I hate sudden loud alarm clocks and this solves that problem well.

I recently bought a clever Philips Hue kit to play with and compare.

Both are high efficiency LED based units with some clever tricks. This should give you some comparison information.

Philips3520 vs Hue

 

Feature Wake Up  Hue 
Power Outage Behaviour Forgets Time – No Battery Backup Turns on Full Brightness.

It is VERY annoying to have lights turn on in the middle of the night after a power outage leaving you fumbling for your phone to turn them off.

Does not forget time or schedule with power interruptions.

Gentle Wake Up 40 Minutes, very gentle and pleasant. 9 Minutes with harsh sudden start at about 30% brightness
Colours Fixed Huge variety
Programming None All sorts of clever options, especially with IFTTT
Style Light comes from 80% from front of unit. Use any fitting you like
Alarm (Sound) Function I never use it None
Reading Light Very good.

Small fiddly buttons.

Unfortunately easy to disable alarm by accident.

Very Good. You need your phone handy.
Power 24V DC 220V AC
Comments Light from the rear of the unit bounced off the wall would be much more gentle on the eyes.

It really needs a battery backup. I have actually hacked a 24V battery into mine to be sure it works no matter what.

Powering on to full brightness after a short power outage at 2AM is very unpleasant.

The harsh startup is also a bit rough. I’m sure both of these could be fixed in software.

If Philips merges these two products, they could be onto a really good thing. Some usability bugs could be readily improved.

Oh – and a good battery backup.

 

 

 

 

 

Easy Trailer Review

I needed a trailer to replace my XF falcon ute. To be flexible enough to replace the ute, I wanted a flatbed with removable sides. That would let me carry longer loads, larger loads, and store it where I wanted. I did not want a box trailer – too many limitations for my needs.

P5010017

I own a large heavy car trailer, so this was to be light and simple instead. Up to the legal un-braked limit of 750kg. As I am legally limited to this weight, it made sense for the trailer to be as light as possible. This would leave more room for payload. Making it extra heavy duty wouldn’t let me carry any more load. I wasn’t planning on using it off-road.

The flat bed with sides would let me use it in more ways. I also wanted to store it winched up to the roof of my carport, over my cars. This would get it out of the way when not needed and keep it out of the weather.

Shopping around at various trailer manufacturers offered almost nothing in the way of flat trailers with removable sides. Several quotes where well over $2000. I considered making my own using an alloy ute drop-side tray, but the cost was still up there. Several manufacturers actively laughed at me when I said I didn’t want a  “heavy duty” trailer. I laughed at them when they said their trailers weighed 200+kg, leaving less for payload.

Then I came across Easy Trailer. A company that gave me lots of options, made a lightweight trailers, and encouraged their customers to customise their trailers. They order over the web and deliver to you.

They specialise in folding trailers, but for me that wasn’t a critical feature. Mine would be stored on the roof, not folded against a wall.

What I wanted would cost me about $1000 from them, and about $400 in extra bits. With rego that’s under $1500, not bad.

Options

I selected a 8ft x 4ft trailer that could tip as well. I added a spare tyre and tie down loops. I recommend 8 tie down loops.

The floors have an option of steel or ply. Aluminium is not an option. Plywood is very good as it gives a “softer” surface that won’t damage what you are carrying. I had 5mm alloy checkerplate at home, so didn’t need a floor supplied.

The sides are the optional heavy duty sides. The front and rear gates double as loading ramps for anything you want to roll onto the trailer. They can come open or with a steel skin. No aluminium option.
Again, for weight and corrosion reasons, I went with 2mm aluminium from a local supplier.

The jockey wheel they have as an option didn’t do what I wanted, so I grabbed a lightweight folding one locally from Repco.

Electrical

The lights supplied are conventional bulb types – that means unreliable. I threw them in the bin and bought better sealed LED lights from eBay. Lights on trailers are a constant source of problems and I hate chasing dodgy light peroblems on my trailers.

To mount them properly, the LED lights I used do need a small backing plate made up to cover the rear. 1.6mm alloy is fine for this. You’ll also probably have to move the number plate and get a light for it. Whilst most conventional lights have a number plate light built in, this is uncommon for LED lights.

As far as I could find, on this size trailer, clearance lights are not required. Despite this, I fitted a set of low profile LED clearance lights to replace the clearance lights supplied with the trailer.

The wiring supplied uses the trailer as an earth – a likely problem spot. As such I used some of my own wire to run a full earth, ensuring all connections where sealed. I don’t solder vehicle connections anymore, finding a soldered connection less reliable than a well sealed crimped connection. The heat causes more fatigue on the wire and corrosion seems to get into the wire further.

Assembly

The trailer comes in lots of bits, with a lot of bolts. Plan on 4-6 hours to assemble it for a first time user. It’s easy enough, just a little tedious.

My assembly tips would be

a) Watch the direction of the C channels, it matters

b) Don’t fit the brackets for the timber stakes, you’ll just have to remove them later.

c) The tie downs replace bolts, figure out which ones as you assemble to save re-doing it.

d) Consider fitting nutserts / captive nuts to hold the sides on. Much less tedious than nuts and bolts.

Review

The trailers are imported from Taiwan, and in some ways it shows in the quality. They are obviously sold worldwide, as I saw one used on the tyre throwing rig on episode 80 of  mythbusters.

The powdercoat finish is ok, but the corners are sharp and will rust there where the coat is thin. I personally wouldn’t leave it out in the weather for too many years, but I say that about any trailer that isn’t hot gal dipped.

The frame is folded U channel steel, bolted together. This gives some flex that should relieve some point strain issues. Unlike a welded trailer, it is unlikely to crack from fatigue. The nuts are all nylocks, so it shouldn’t rattle apart too easily, although it would pay to check the bolts every so often.

The axle is folded steel, not solid bar. It would not stand overloading well. The drawbar is also C channel, so I wouldn’t overload it.

The compliance plate on mine was for 500KG. I spoke to Easy Trailer and they sent me another one for 707kg, the advertised max weight. The design is clearly for a distributed load, so if you are planning on carting large rocks or engines, be careful where you load them.

The wheels are 12” cross ply tubeless tyres on cheap steel rims. This is good for me as they keep the trailer low to the ground and keep the overall weight down. Cross ply tyres have a much heavier load rating, – these are a small narrow tyre.  The studs on the hubs weren’t drilled particularly square, my only complaint. Some people worry about small tyres at highway speeds. Mini’s work just fin on 10″ wheels at much higher speeds than this trailer will ever see. A wheel bearing’s RPM has nothing on a tailshaft.

I added an extra brace for the spare wheel to stop it twisting when stood on. I also added a swing up jockey wheel and extra tie down points. I tend to modify my stuff though.

The assembled trailer with sides on weighs in at just over 100kg, leaving 600kg of payload.

I have used it to transport my 200kg motorcycle, mates bikes, mulch, cane mulch bales, timber and other random items so far. I would not overload it badly. I would not take it over 1000km of corrugations and expect it to survive.

I like it, I love the lightweight design, I like the suppliers attitude to customising it, and I like the price. It tows well and is very flexible.  It’s unfortunately invisible behind the Landcruiser, I’ll need a reversing camera to see the thing.

An LED Birthday for all my Maglites

P5010019

I love my Maglites. I know technically there may be better out there, but they have such a nice solid feel to them as you thump them over someone’s ….. err, well, anyway.

Whilst they are good quality, they very old tech, so a swap to LED’s was in order. LED’s offer greater output, 5 – 10x battery life, and are much more shock proof.

The debate as to “which bulb is best” goes on endlessly, so I settled for those that I could source from eBay and post to Australia.

The direct bulb shaped replacements are very rare in high output versions. Most inserts offer an unusual shaped fitting and often a different reflector.Standard shaped bulbs often can’t dissipate enough heat to keep an LED cool. LED’s hate heat for effective output. Some LED’s will start out quite bright when turned on, then dim somewhat as they heat up.

The Maglite brand LED replacement bulbs are nothing special according to most reviews, and I wanted something with some more power.

Manufacturers appear to have come and gone, so don’t be surprised if the bulb you want is no longer around.

One downside with many inserts is you lose the focussing ability. In some cases they are do much brighter it doesn’t matter.

Terralux has a good range of inserts, with a balance of cost, features, output and availability. They are readily available on eBay US.

Candlepower Forums has in depth discussion and reviews, detailed comparisons etc. As the space changes so quickly, many of these are out of date.

Regardless of which bulb you choose, it should by preference be regulated. This keeps a constant brightness and gets best possible use out of the batteries. You don’t need to throw them away until they are fully used up, and lose very little brightness as they discharge.

Alkaline batteries have limits on how much power you can pull out of them. Essentially, if the bulb you choose will flatten the batteries in under 10 hours, the battery won’t give it’s full rated output.

When I started this I was going to do lumen comparisons and shots of beam patters, but honestly, it changes so fast, and others have done this already. I figured I would just put down my experience and you can pick bulbs on your own.

Maglite 4D CellTLE-300M-EX
The brightest insert I could buy, with 3 x 2w elements. It’s not focusable, but so bright, it doesn’t matter. 3 brightness levels. The three elements produce a consistent beam pattern. 700 Lumens. About $70

All the other bulbs have been discontinued already.

An eBay search shows most bulbs are around 100 – 300 lumens and about US$20ish.

They are all an upgrade. Every brand and model seems to differ in it’s focussing.

Factors I would consider are

  1. Price
  2. Lumens Output
  3. Focus – ability
  4. Regulator

Not pictured is my Maglite solitaire, it was upgraded with one of these.

image image
Yes, that is an active device, there is a regulator in the round disk.

For about $150 all up, it was well worth doing the six lights.

Finally – Reliable Cordless Phones and VOIP on Naked ADSL

When I changed over to Naked ADSL2+ with Internode, I had to sort out a replacement for the home phone. It was a tough journey and about 12mths of problems before I found a reliable combination of devices.

The problems ranged from

  1. Failure to ring
  2. Low Volume
  3. Dropped calls mid call
  4. One way voice
  5. Poor call quality

After 12 mths of drama’s I found only Panasonic DECT handsets where reliable with the VOIP solutions.
I also found that running a “single box” solution is less hassles than “multiple box” solutions.
DECT has a much greater cordless range than most other handsets.

Here are the combinations I tried and the issues associated.

Routers

Netgear WNDR5500 + Netgear DM111p + Open Networks 812L VOIP

  1. Rubbish combination, awful reliability, even after warranty replacement.
  2. VERY unreliable, mostly due to router
  3. Telstra DECT and Uniden WDECT = heaps of problems as well
  4. My WNDR3300 review here

image image image

Netgear DG834G v3 + Open Networks 812L VOIP

  1. Very reliable, very stable, but limited features
  2. Reliable with fixed handset
  3. Unreliable VOIP with Telstra DECT and Uniden WDECT Handsets

image image

Billion 7404VNPX

  1. Single box resolves interop issues on volume and ringing
  2. Took a few firmware versions to improve reliability
  3. Still needs rebooting for DHCP reliability
  4. Fast
  5. First unit was buggy, replaced under warranty
  6. Reliable calls only with Panasonic handsets
  7. Billion recommends only using fixed handsets, not cordless (from their support line and whirlpool)

image

Cordless Phone Handsets

I prefer to use 1.8GHz DECT handsets where possible, they have MUCH (2x-10x)greater range than 802.11, and don’t use the same 2.4GHz wireless spectrum. 5.8GHz has worse range than 2.4Ghz or 1.8Ghz. Higher frequency = less range.

There seems to be some issues with call stability and cordless handsets. I can only guess from all my testing that it relates to off-hook detection. I played with every setting under the sun, and nothing helped. 12mths of stuffing round to find that Panasonic handsets work well.

  1. Telstra Touchfone T200
    Fixed handset – works well in all circumstances, if the router allows the call in.

  2. Telstra DECT Cordless – Poor quality and hang up problems, poor call quality and cheap handsets.
  3. Uniden WDECT – LOTS of problems with VOIP, don’t bother. AWFUL.
    The problems are twofold. Radio interference is a nightmare, even when seperated by 10+M
    The on/off hook sensing of the router and the base station appear incompatible, hanging up on calls all the time.

  4. Panasonic DECT – Worked well

Dorcy LED Torch

Cheapest LED Bulb

Here’s a great hack. KMart is selling these torches for about $3.50 with batteries. The LED in this is fitted to a normal sized bulb fitting, meaning it can be taken out and put directly into any 2 Cell torch, AA, C or D.

P4090002

http://www.dorcy.com/products.aspx?p=412503

It’s a very bright 10mm LED in a normal bulb fitting. No regulator circuitry.

This has to be the cheapest source of LED drop in bulbs for torches I have found. Or you could just use the torch.

The beam is much brighter than a normal 2 cell torch. Runtime would be significant, although I haven’t done a full runtime test. You’ll use far less batteries, better for the environment.

Beam pattern is an average spread.

Versys KLE650 vs VStrom DL650

Review from someone that has owned both.

image image

Summary

Despite very similar specs, these are two very different bikes.

Versys is more “fun” to ride round town, but not so comfortable on longer rides in stock form.

VStrom is better to customise and tour on. it has ABS.

Average 300km fuel range

The Versys had Michelin Pilot Road 2 tyres – wonderfully sticky. Despite having very similar dyno charts, the Versys definitely feels more torquey and pulls much more when over 160km/hr. The Versys suspension is far to harsh on less than perfect roads, even after tuning it as far as I could. I find this a major failing on a bike sold for it’s long travel suspension.

The VStrom tyre choice on road is not as sticky, but has a better range of off-road tyres.
The VStrom with Racetech fork valves and springs is a much better beast than stock, with steering sharpening up, and brake dive disappearing. Before it was a bit soft and somewhat harsh.

Drag racing them side by side shows the acceleration from 1st to 6th is basically exactly the same. Seat of the pants though feels like the Versys is MUCH snappier. Ass Dyno wrong again.

Braking is interesting. The ABS gives the VStrom an unfair advantage. I have tested the ABS in both wet and dry conditions finding it reliable in both. It tested at 1.05g using Dynolicious on the iPhone, vs only 0.82g for the Versys.

I am replacing my Versys with a VStrom, as I prefer the range of parts available, ABS and the different feel especially on the highway. The Versys is more fun to ride round town, if you can ignore the issues.

Great new CFL Downlight

When I renovated the house I installed a heap (18) CFL downlights in the ceiling which I reviewed. These 15W reflector CFL’s warm up fast(ish) and provide good light.

image P1270005

I was never happy with the kitchen bench though – it wasn’t bright enough. I recently bought a light meter from eBay and confirmed my suspicions. 60 Lumens at the bench top whereas kitchens are recommended to be around 150 lumens.

Surprisingly under my range-hood with it’s pair of (yuck) 20w G4 halogens scored 140 lumens.

I tried replacement bulbs in the downlights to get additional brightness with no success. The 18W Philips reflector is larger and does just fit. It’s only available in Warm White which made it seem no brighter and not match the rest of the house. I tried a larger 23W Par 38 spotlight, but it doesn’t fit into the housing, and is too large and heavy.

I thought I might need more spotlights on the wall until I made a new discovery.

image      image

http://www.pierlite.com.au/au/3091/dot-110 is a silvered reflective downlight housing that takes a normal ES bulb. By putting the silvered reflector in the housing, rather than the bulb, means you can use a normal bulb without losing all the light.

It comes with a Philips 20W ES Warm White bulb. I tried both a Philips 23W Daylight and 23W Warm White, much preferring the Warm White.

I’m impressed – this thing is BRIGHT. You do not want to look at it running. The benchtop now measures 160 lumens, up from 60. Great for a kitchen

23W is 3W above the rating of the fitting, but being CFL – I’m confident it won’t bother it. The 20W is also available in Dimmable, for those that want to replace 50W halogen downlights, although an electrician will be required, and the fitting is somewhat larger.

Another excuse not to go CFL’s down.

Physics and a great laptop cooler

I recently bought a fanless laptop mat for use with my Dell e4300. When sitting in the lounge with the laptop on my lap it gets a bit warmish for my comfort. The fact that my clothes block it’s cooling vents certainly doesn’t help.

image

These new thingies work on a very cool principal of thermodynamics. Normally when you pump heat into a material it’s temperature increases. If however that material is at a point where it’s phase changes (solid – liquid or liquid – gas), then until the phase change is complete, all the energy you put in will not increase the temperature of the material. This is known as the “Enthalpy of Fusion” and the “Enthalpy of Vaporization”.

The really nifty thing is that with the right material, it can take huge amounts of energy to change it’s state compared to simply changing it’s temperature.

Quoting from Wikipedia

The high heat storage capacity in the phase change from solid to liquid, and the advantageous phase change temperature of 32 degrees Celsius (90 degrees Fahrenheit) makes this material especially appropriate for storing low grade solar heat for later release in space heating applications. In some applications the material is incorporated into thermal tiles that are placed in an attic space while in other applications the salt is incorporated into cells surrounded by solar–heated water. The phase change allows a substantial reduction in the mass of the material required for effective heat storage (83 calories per gram stored across the phase change, versus one calorie per gram per degree Celsius using only water), with the further advantage of a consistency of temperature as long as sufficient material in the appropriate phase is available.

As such – it literally soaks up the heat without getting significantly warmer itself. There is a caveat though – once it’s adsorbed all the heat it can – it will start getting hotter along with the laptop. For this reason you can only use it for a certain number of hours before letting it cool down and “reset”. The manufacturer quotes 8 hours, however this would vary significantly depending on the power of your laptop, and the ambient temperature. Mine works fine for 3-4 hours. As my laptop only gets hot on one side, I can just turn it around to get twice as much use out of it.

They also have a dimpled surface to allow some air to the laptop, and mesh underneath to help keep some distance. They roll up, but aren’t super light. I wouldn’t bother travelling with mine as I don’t tend to sit with my laptop on my lap very often when away. I could see it being useful watching movies in bed where the sheets stop the ventilation.

The only issue I see is they do limit airflow somewhat, possibly making the laptop run hotter.

You can buy them online at the link below.

Recommended – 4/5 as I love thermodynamics and this is cool!

Rethink your Lid

Buying motorcycle helmets used to be easy. Plastic was crap, Fibreglass was good, Kevlar / Carbon was best. If it was a Shoei, Arai or Bell it was good, everything else was only OK.

BUT – interestingly enough, every single helmet you could buy had passed the crash test standard, so the better / worse was opinion, nothing more. In Australia this is an Australian Standard (similar to the US DOT standard, and many others). Really, it’s a “minimum”, everything on the market is better than the standard, it’s just a question of how much.

There was a defacto “better” standard – Snell. This was only issued to the “best” helmets, so if you cared, you bought a helmet that also had Snell certification.

Well now there is something better. The UK govt has setup a research and testing laboratory to test and rate motorcycle helmets like they crash test cars – with a star rating. You’ll find it at http://sharp.direct.gov.uk/ 

The testing is based on the new EU standard ECE 22.05 and discussed on webbikeworld.

I just bought a new Shark RSR2 to replace my aging Arai Qantum(1996). The new Shark is comfortable, quieter than the Arai on my head, and has a 5 star rating.

I prefer the new EU standard over Snell etc after reading this debate on MotorCyclistOnline and the testing they did. The base concept is that the Snell standard is very tough, and a tough helmet is not as soft and squishy. Soft and squishy is more likely to be useful to you in the accidents you are most likely to die from. The more serious accident that the Snell rated helmet is designed to protect your head for, will leave you dead from other injuries and with brain damage anyway.

Of course nothing will protect you from those big ones that just leave you dead.

WD External USB HDD’s do Spin Down

I’ve been trying to reduce the power of my Home Server and Media Centre. Since my Power Meter debacle, I am now re-testing all the equipment and getting some rude shocks.

One of the positives out of this is that my 1TB Western Digital  My Book Essential and 300GB Western Digital My Passport Essential both spin down and save power. On USB, this is a nice feature, as many of the generic external cages don’t spin the drive down.

The WD’s spin down on XP, Vista and Windows Home Server which is based on Server 2003. The timeout appears to be independent of the OS settings.

They support several power modes, and my current meter is not accurate enough to report which one they are in.

The WD 3/5″ Black is the 7200RPM desktop drive.
The WD 3.5″ Green is the 5400RPM drive generally in the MyBook
The WD 2.5″ Blue is the 5400RPM drive generally in the MyPassport

Model C’pcty Operate Idle Stdby Sleep
WD 3.5” Black 1TB 8.4 7.8 1 1
WD 3.5” Green 1TB 5.4 2.8 0.4 0.4
WD 2.5” Blue 500GB 2.5 0.85 0.25 0.1

The other thing I noted was that my new power meter (which is not rated as accurate below 10w) indicated that whilst sleeping, the 3.5″ and it’s power adapter were drawing less than 1w. The power adapter was only just warm, much better than the usual little heat wasters. Well done WD for killing the parasitic standby power.

Overall, they get my vote as low power green storage.

The Green 3.5″ and Blue 2.5″ drives are also very quiet – both operating and seek. The 2.5″ is quieter, but with half the capacity, may not stack up overall.

And you can always decode the Morse Code on the outside!

4WD Winch without the Weight

I wanted to fit a winch P4260063to my ’98 HZJ105 without wearing a huge  weight penalty, or spending too much money. That ruled out walking into ARB and handing over the Credit Card for a new Bullbar and Warn. It meant I had to DIY this little exercise.

I wanted to keep the weight down, so decided a 9500lb was smaller and lighter than a 12,000lb. If I needed more pulling power, I would use a pulley block.

After reading the SA 4WD Winch Review, and getting a good deal, I bought a 9500lb Ironman Winch for $625 w/ 3yrs warranty. They are claimed to be waterproof and come with what I needed. I would have preferred a Premier winch due to the brake not being in the drum making it more suited to synthetic rope, but it was out of my price range. I would really have preferred a hydraulic Milemarker, but that was really really out of my price range, especially when I factored in questions around power steering pump flow rates.

After using steel cable and hating it, synthetic winch rope was a requirement. I figured 100ft (28M) of 5/16″ (8mm) rated at 13,700LB breaking strain would do. Less rope on the drum keeps the winch closer to it’s rated pulling force. I specifically bought their “Hybrid” line, where the first 25ft is a Technora based rope, and the rest is Amsteel Blue. The Technora is more temperature stable for use on winches with a brake inside the drum. I bought mine from www.cseoffroad.com, along with the alloy fairlead, rope protector and safety thimble. The alloy fairlead was a free bonus at the time. I also grabbed 100ft (28M) of 3/8″ (10mm) Amsteel Blue winch extension rated at 19,600lb breaking strain. The separate extension allows the flexibility of simply extending the pull, connecting two different points, putting a winch block in between the two etc. You need the thicker rope size if you are going to use a winch block, as it will double the pulling force – 9500×2 = 19,000lb.

The next item was a mount. Other mounts I have seen use 6mm steel plate in various arrangements. I settled for the thickest and strongest alloy channel I could get – 8.4mm x 6.8mm tempered alloy. It doesn’t have a rated “strength” in this configuration, especially after I chopped it up to get the winch to fit. I can say that in a pull to stall test, the rope snapped before the winch stalled, and the mount, while having a slight twist, suffered no permanent deformation. The winch is in an ideal position, directly between the chassis rails, very low, and as far back as possible. The mount acts to protect the radiator from sticks etc.

The fairlead I mounted into the bullbar with 20x heavy gauge rivets. Whilst I am not that confident as to their strength, in shear the steel pins combined with the tight fit should be very strong. At a 45deg pull they will be in both tension and shear, a less desirable situation. The alloy bar mounts are particularly weak in a sideways direction, so I think I’ll be avoiding heavy angled pulls. The fairlead needed to have it’s inside edge rounded a lot, as the winch sits quite low in relation to the bar.

Finally it was just a matter of the control box hidden inside the bar, the wiring and lockout switches. I recommend the lockout switches be waterproofed underneath with silicon, and rubber caps fitted (I used rubber “feet”). Water pulls inside them and the copper contacts stop working.The winch is wired with a switch to each AGM battery, letting me use either one, or both.

By dropping the steel cable and roller fairlead, using an alloy mount, not using a 12,000lb winch and keeping the alloy bar I have kept nearly 75KG off the front of the car. Just as importantly the weight is as low and far back as possible, something most winch bars don’t do. Whilst I accept it’s not as strong as a steel winch bar, it has passed every test I can throw at it so far.

Finally – it’s a whole lot cheaper than driving into ARB, and with Mickey T MTZ’s, twin Air Lockers and some lift, hopefully I won’t need to winch too often (yeah right).

Windows Home Server & PP1 – I’m impressed

When I first heard about Windows Home Simageerver (WHS) – I was pretty reluctant to bother. I was happily running Server 2003 with a 1.5TB software RAID 5 array and am not a fan of NAS, so didn’t get the point.

With the release of Power Pack 1 (PP1), and support for external USB backups, I decided to take another look. I have not looked back.

OK – at it’s simplest WHS does three things

  1. It backs up all your home PC’s using what has to be one of the most innovative and useful backup solutions I have ever seen.
  2. It’s a file server
  3. It’s a Terminal Services & Web Gateway – you can get access to your desktop PC’s and Files from the Web

WHS is managed by a really easy to use interface – it’s not a web interface, it’s actually a Terminal Services Published App. Anyone with a modicum of IT knowledge can drive this thing.

The hardware can be any old PC with more than 512MB of RAM. I run 4GB so I can use VMWare are well for testing. It will need a few HDD’s, either internal or external, USB, PATA, SATA, eSata, it doesn’t matter. They can be any size and speed, it will sort out the storage. Ideally there are four HDD’s, one for Boot / Temp, two for storage with duplication between them, and an external USB/eSATA for backup. I’m using a WD 1TB Mybook Essential for backup as unlike many enclosures, it will spin down saving power, and has no fans making noise. I’m running 1 x 80Gb, 4 x 500Gb, 1 x 1TB USB.

Install

Installing and setting up the WHS is pretty simple. I had one weird error that caused it to fail due to it not liking the PATA setup on my M/B. Changing the DVD to it’s own controller solved that.

There is one strange requirement, that is the server must be plugged into an Ethernet interface, not wireless. It’s something to do with the compression algorithm and streaming of the backups. It’s documented, but I haven’t found the solid reason yet. The clients can be wireless, but not the server.

Next step is to configure any storage. Plenty of guides on that around. The very interesting technical brief / whitepaper on WHS Storage is here. It must be noted that WHS does NOT support RAID. You can run hardware RAID, but it’s not recommended. Please read the whitepaper to gain a better understanding. Basically any of the file shares can have “duplication” enabled. Initially to me this sounded like a mirror (RAID1), and as I was running RAID5, I wasn’t particularly interested. After reading the whitepaper, it is fundamentally different. Not better or worse, just different. I would kinda still prefer RAID5 – it’s more efficient, and protects the whole system, not just the file stores, but this is much easier to expand and configure. I’m neutral on this feature vs RAID5, but would be very happy to give it to a non IT person to run. I think that’s the main point, anyone could drive this and have their data protected. It does NOT protect the WHS OS in any way. It does not duplicate the PC Backups unless you hack it.

Once the server is setup and configured with storage you install the WHS connector on each PC in your house. There is a tray icon that will run on each PC in your house – it alerts you to any problems, provides shortcuts to the file shares, manages backups and allows you to manage the WHS. It makes it much easier to trust the status of the server than having to remember and check Event Logs every so often.

Backups

The backup function is split into two components. PC backup and File Server backup. The technical brief for the PC Backup is here

PC Backups

The PC backup runs once a day, waking the computers from sleep, and putting them back to sleep when complete. The backups are particularly clever, tracking each NTFS sector backed up. If any sectors are the same, either across backups of the same machine, or between machines, the sector is only stored once. This is all transparent to the user. The space saving is dramatic. My three computers at home are using 168GB backup space, and that is with plenty of data on each, and nightly backups for a month. The backups are cleaned up to manage space on a schedule you can define.

Restoring of PC Backup’s can be done in one of two ways. You can browse the backups to restore individual files, or you restore the whole machine like an image. The restore is particularly clever. You boot the PC from a generic “Restore CD” that comes with WHS. All the drivers for that PC are sitting in a folder on the WHS ready to go – it has automatically found them on the PC when it was backed up and prepared them for this purpose. They go onto a USB thumb drive. With the drivers available, the PC can get onto the local network, connect to the server and retrieve the backup. It will put all the files back, OS and all – presto – rebuilt client PC from backup. That is much easier than the usual “restore the OS first”. Unlike most Bare Metal or Image restores, there is no need to keep regular updated images, meaning less maintenance and less space consumed. It’s very elegant really.

Server Backups

The server backup can backup any of the file shares (not the Server OS or the PC backups) to any HDD in the “Backup Storage” list. The server backup must be triggered manually, it cannot be scheduled or automated (A glaring oversight). It uses NTFS Hard Links to make sure that any file is only stored once, even though it may appear to be copied up each time. This saves huge amounts of space, and can be read on any machine. Again – this is transparent to the user. The external backups must be cleaned up manually when you run out of space. It would be ideal in future versions if these external backups could be duplicated somehow, to allow for an offsite copy. The current solution would be to perform the backup twice. This is not a significant overhead, as the backup only copies any changed data using a very efficient algorithm.

Storage / Shares

The other function for a WHS box by default is as a local file server. It is very easy for anyone to configure this, and can be controlled with easy to manage user accounts and permissions.
The interesting feature in this area is “Duplication”. Each share can optionally have “Duplication” enabled. This will then have the server transparently copy each file to a separate drive. The process is described in the storage whitepaper. This is all hidden from the user by using NTFS links and other NTFS trickery. The advantage is that in the event of a disaster of some kind, the drives are fully readable on any machine. It also is dynamic enough that the drives can be any type  and size, it will share the data round and balance the storage as required.

Web Gateway

I haven’t played much in this area yet – I’ll update when I do. It uses UPNP to publish a site to the internet through your router. The domain homeserver.com lets you register a free subdomain to get to your data. You can access your files from anywhere. There is a Terminal Services Gateway function to allow remote access to your home PC’s – I haven’t investigated this yet. It probably depends on your desktop OS version, user account configuration and if the computer is asleep.

Add In’s

There are a reasonable and expanding number of AddIns that can be installed. These offer increased functionality through the WHS interface.

Notes

It is worth checking the Power Settings on the WHS, as mine was set not to spin the drives down. This wastes a lot of power and will reduce their life. I tend to set mine to 5 minute spin down, as this is longer than any streaming period. The machine isn’t user interactive – so spin up time is not a concern.

Non-WHS Apps

WHS is actually Windows Server 2003 (possibly with some SBS stuff – I have noted). It will run nearly anything W2K3 Svr will. BUT, you need to be particularly careful with your drive management. Use of Disk Manager can kill the special WHS stores. Whatever apps you install needs some careful thought as to where the data will be stored.

Conclusion

I’m very impressed with the data storage and backup solution used in WHS. It can be driven by anyone with a modicum of computer experience and meets it’s goals very well. It is more limited than a full W2K3 server, but offers some brilliant functions that are difficult to find elsewhere. It’s simplicity is wonderful, and with some care, offers a wonderful solution.

The Future

What should have been included that wasn’t? Hmm, well. I have a list, as do many others on the Connect forum. If I had to narrow it down it would be.

  1. WHS + Media Centre in one – so you can just run extenders around your house.
  2. Scheduled External Server Backups
  3. OS Backups
  4. A 2W Atom CPU / MB & 95% efficient CPU – drop the consumption from the 30w idle of my Home Server
  5. Better power options. It would be good to have the box sleep for much of the day, waking only to do what was needed when we were home.

VSO Image Resizer – Works well for me

When I upgraded to Vista, I lost the ability to run one of my favourite XP Power Toys – Image Resizer.

I like to be able to resize stuff easily and quickly for a number of uses. It’s one of the main reasons I use Live Writer for this site – it’s quick and easy to to the image management.

Luckily a free replacement with all the simple “Right Click – Resize” features turned up – VSO Image Resizer. And it’s free for personal use.

No spyware, no crap running in the taskbar, no background services. It runs the way an app should – right click – “just do it”

Highly recommended.

T-Amp and Paradigm Atom Review

I like music in my house and have a mild audiophile fetish, not as bad as some, but enough. I wanted a nice system for the main living room that would be used for background music, the loud stuff being out on the deck, or in the home theatre room. Despite being quiet, it still had to be “nice”.

It also needed to be small an un-intrusive, and fit on some small bookshelves. This ruled out most amplifiers, as they just don’t come in small sizes.

For the speakers I settled on a set of Paradigm Atom bookshelf speakers as reviewed here. Steve at Eastwood HiFi was most helpful and I recommend them and his entertaining site.

I initially considered a Fatman Valve Amp to power it, but with my green bent, the inherent inefficiency of vacuum tubes, and the cost, I looked at other solutions.

The T-Amp got amazing reviews and some impressive comparisons in it’s various incantations based on the Tripath Chip Class T Amp.

I picked up a Gen2 T-Amp from eBay.com for US$60 plus postage. The power adapter was full multi-voltage / multi-frequency and worked on Australian power. The unit is TINY, you can see from the pics below how small it is.

Once powered up, I connected the iPod and started to test. I was initially concerned that the 90db efficiency of the Paradigm speakers wouldn’t be sensitive enough to get reasonable volume from the meager clean 10w/channel and 15w maximum.

Amazed is an understatement. The volume is more than acceptable, although not ear shatteringly loud, it’s more than loud enough you can’t talk over it. Beautifully clear,  and very simple and clean. The efficiency must be well over 90%, as several hours in, there was no heat from the amp whatsoever.

This thing gets my vote, beautiful clean power, dirt cheap price, tiny size, and as eco friendly efficient as you can get.

I’m very impressed.

Netgear Dual Band Wireless N Review – WNDR3300 & WNDA3100

Speed, I need speed, and speed with coverage would be good. I was using a Netgear DG834G previously, and had a pretty good run out of it. I know Netgear kit ain’t the best, but it beats DLink in my experience, and is probably the biggest selling home and SOHO kit in Australia.

Now for 802.11g, MIMO will improve your coverage, but seeing as N is just around the corner, and uses MIMO as part of the draft standard, it made sense to just jump to 802.11n. My house is two storey, and getting good reliable coverage over both floors has proved difficult. I always get a signal, but not a good one, and for streaming my Vista Media Centre from my Home Server, I needed a good signal. I could have run Cat5, it’s what I had done in the past, but I figure, in 2008, I should be able to make all this new fangled stuff kinda come together smoothly.

Just released by Netgear and Linksys amongst others are new Dual Band draft N equipment, this runs in both the 5.8Ghz and 2.4GHz ranges. The argument being that the 5.8GHz range is far larger in frequency space, and far less utilised by other things that can interfere. Made sense to me, and at a small price premium, was worth jumping onto. Teamed with a new naked ADSL2+ service, I figured I would “embrace the future”.

The new Netgear model is WNDR3300 and the Linksys a WRT600N. I was more familiar with Netgear, it’s cheaper, and more easily available in Australia. I teamed it up with a set of Netgear USB WNDA3100 adapters. The unit supports QoS for my new Naked ADSL w/ VOIP service and has the widest range of features of the current netgear lineup.

8 Weeks after ordering, the kit finally turned up, with delays from Netgear getting it into the country. Looks like this stuff really is new – oh bugger, that’ll mean bugs.

It looks the piece, big, black, no antennas thanks to the secret metamaterial. The power pack is switch mode and small, and it comes with a few cables. Inital setup is manageable. The flashy lights on top are very very irritating, allow an extra $2 for a roll of black tape.

The first problem was the Router doesn’t have an integrated ADSL modem. Guess I should have read the specs a little better there. It’s almost impossible to purchase an ADSL modem only unit in Australia today, everything wants to route. Two routers in series = problems. You can convert the DG834G into a modem, but I had another home for mine, so I bought a DM111P to run as an Ethernet to ADSL2+ bridge. Getting the DM111P to be a modem means putting it into “RFC2684” mode, something not covered in any of the docs.  This way the DM111P handles the ADSL settings, but the WNDR3300 does the ADSL PPOE login with credentials etc. The downside is that you can’t see your ADSL line connection performance figures, and whilst the DM111P is in bridge mode, it doesn’t have an IP address, so you can’t get information off of it either. You have to configure your WNDR3300 to login with “Other” and not “PPTP” or “Telstra Bigpond”. Either way, I’m getting about 7Mbit.

Once running and configured I fired up the WNDA3100 units in my partners desktop and the Media Centre. Install went OK, although I hate the “app” type driver installs. I much prefer just having the driver and managing it through windows. I figured being new, that doing it the “right” way with the vendor, and having additional signal information would be useful. Longer term, once smoothed out, I’ll be uninstalling the netgear apps and just running the driver. That said, I have to figure out how to extract it, as it’s all packaged up, and not easy to get into. Finally, there is some sort of script it runs on every login, looks dodgy to me.

The coverage is good, and speed ok. Plenty of other reviews there, no need to re-cover that. Interestingly most of the clients could only see the 2.4Ghz signal. The 5.8 signal gets wiped out by my walls too quickly. As this review covers, you can only have DraftN on either 5.8 OR 2.4 at once, so I dropped the 5.8 signal and got the speed where I could. That pretty well negates the point of having Dual Band.

The comments I have had so far are below

  1. Integrated WNDA3100 drivers mean more junk running
  2. The pretty blue flashing ultrabright LEDS on the router are really really irritating, and there is no “off” option. (Update – press the dome over the lights – they turn off)
  3. The router firmware is very flaky. It drops wireless signal every so often. (Seems better now)
  4. The WNDA3100 drivers are less than ideal – more work needed here to improve performance.
  5. My 802.11a/b/g laptop only wanted to see the 5.8 signal, not the 2.4, until I turned off the 5.8 on the router totally.
  6. My HP printer wouldn’t work with WPA2, I had to turn on WPA/WPA2 compatibility mode.
  7. If running in 2.4/5.8 Dual band mode, you get the option to run two different SSID’s. If you run the same one, your client can be confused as to which one to use. There is no guidance I have found on this function anywhere, and I’m still confused. Caused me some grief, until I made them different, at which stage the WPS auto config function stops working properly.
  8. My Outlook w/ RPC over HTTP refused to work until I upgraded to the Beta firmware. (Fixed now)
  9. Netgear has a Beta program going for firmware and some decent forums
  10. There is discussion of other USB NIC vendors with the same Atheros chipset having performance issues.
  11. The modem and power adapters all produce a bit of heat, meaning they are not particularly efficient. I am trying to cut my power use.
  12. The DM111P comes with an old style power brick, whereas the WNDR3300 has a much smaller and more efficient switch mode power adapter. C’mon Netgear, catch up.
  13. Coverage is much better
  14. Speed is much better
  15. No driver support for the WNDA3100 and Server 2003. I haven’t done video tests yet until I get a NIC for the server.

Next time I think I would consider the DG834N with the integrated modem, unless I had spectrum issues, possibly in densely populated areas.

Update (31/07/08)
I have updated to the latest release firmware – this has helped the stability significantly. Coverage is still ok, but not excellent. Primarily, I still can’t reliably watch DivX/XVid movies on my Vista Media Centre PC from my Windows Home Server. They play, but often judders and stall. The signal strength an quality are about 70% – but it still doesn’t cope. I think I’ll have to run Cat5 to the Media Centre after all. The Home Server is already running Cat 5 to the WNDR3300 – that is a requirement of WHS.  My house is two storey timber and no too huge. Due to placement, some transmission paths are less than ideal – high angle to the walls / floors increasing apparent depth.

UPDATE:
I have decided to ditch the WNDR3300 and replace is with *something* else. I ahve gone through 5 versions of the firmware since I bought it. The 5.8Ghz is a waste of time, it has very poor penetration. www.smallnetbuilder.com shows average-poor wireless performacne in comparison from other devices. THe unit was replaced under warranty a couple of weeks ago when the QoS rules would not remain set to custom.

 The final deal breaker was my VOIP phone dropouts. I have an OPEN networks VOIP ATA behind the router, and frequently get “one way voice” on a call. I put this down to VOIP issues. Whilst the router was away under warranty I used my old DG834G – and had NO call dropouts. It doesn’t even have QoS and the call quality was better. As soon as the WNDR3300 went back in – dropouts came back. It’s going to be replaced, this time with somethign with an integrated ADSL modem.

I would not recommend this device.

How to destroy your Mont Blanc Pen

It’s rather simple really. When the ink refill leaks and you have to wash it out, use Methylated Spirits. A few days sitting in metho to soften the old ink will result in the pictures below. Note, it wasn’t my pen, but I did supply the metho. Nothing on the web I have found so far indicates the special Mont Blanc resin they use is not alcohol stable. Not a bad effort for a several hundred $ pen. I’ll stick to my Fisher Space Pen.

Review – 4WD Systems Fridge Slide

At $245 + $35 postage, the fridge slide from 4WD Systems seemed like a decent deal. I later found out that the genuine Waeco was about the same money, and probably a better unit. The Waeco slide is spec’d at 15KG.

The one I bought is worth the money as scrap steel however – weighing in at 20KG, it weighs more than my entire drawer system. I’ll be “modifying” this to reduce weight significantly when I can afford a plasma cutter.

It’s a fridge slide. The fridge slides in and out. It kind of stays out, depending if the locking mechanism lines up that time or not. The straps it came with were a joke. P1080146
Looks like slides from a computer server or filing cabinet. Surprisingly they don’t rattle. The locking mechanism does however rattle a little, as sympathy with the travel stop which squeaks. P1080145
Very solid construction. The amount of plate steel used here is amazing. Unfortunately it wasn’t enough to stop the carpet bowing it up in the middle and rubbing on the sliding tray. You can see the rub mark where it has damaged the paint and scored the steel. The clearance here was inadequate to start with. P1080143
You can see I have screwed it down. It comes with 4 small screw holes, 2 of which are covered by the tray. Total disassembly is required to screw it down firmly. P1080144
The tray rubs underneath as well. P1080147
The offending locking mechanism that needs a grinder taken to it. P1080148

Well it’s difficult to install, requires modification from new, squeaks, rattles slightly, slides poorly, jams open, doesn’t lock open, and weighs far far too much.

BUT it is pretty solid, and could be modified to be better.

Score: 2/5
I’ll get a lightweight one. Or one of these drop ones for the missus although $449 is a bit more expensive and I haven’t seen a weight.

Review – Just Straps Fridge Straps

I purchased a pretty average fridge slide to complement my home made shelf / drawer system before a trip over XMAS. The straps it came with to tie the fridge down were a simple “loop” type with a plastic tensioner, as you tend to find on kids school bags etc. The problem with these is two fold:

  1. They are difficult to tighten as the lop just goes round and round as you try and tighten it.
  2. They make it very difficult to remove the fridge as each strap has to be unthreaded back through it’s buckle. A tedious job for the rear ones.

Loop straps on a fridge are a silly idea.

Just Straps to the rescue. These came from BCF, even though I hate the place. Super Cheap Auto of the camping world. They are 25mm webbing rated at 150KG each. A big accident might break them loose, but I think the fridge or slide mounts will fail first. P1080142
They are in two pieces with a strong steel hook and loop connecting them. One part stays with the fridge, the other with the slide or tie-down points.

The fridge end has a loop to feed through itself. The base end has a length adjustable steel buckle.

P1080140
The loop that connects is together is a gripping “tiedown” tensioner, allowing a 2:1 mechanical advantage. Great for getting it down nice and tight. P1080141
All tied in, it won’t move no matter what happens. P1080139

Highly recommended. 5/5
They are quick, simple, easy and strong.
