Sometimes my Nokia N95 battery seems to last forever, other times it just dies – it depends on coverage, what Gravity is doing, and if I’ve been using WiFi. Similarly my iPod touch can last days or suddenly die. NEED POWER. Or rather, I need portable power.

I’ve seen both @ilicco and @documentally using powertraveller products (and they had won a Queen’s award for Enterprise), so when I saw a discount code on Twitter for 20% off I caved in. I also wanted to grab the opportunity to reduce electricity consumption (saving on stand by power is going very well so far), so I went for the powermonkey-eXplorer. It’s basically a booster battery which can be charged by mains, USB or solar power.

It’ll live in my rucksack,  so if my phone or iPod go flat I always have a way to charge them, even on the move. On longer trips I’m hoping I can charge them from the powermonkey and then recharge the powermonkey via it’s solar panel.

The whole experience so far has been great – the powertraveller store is really well laid out and nicely written – got to love the way that “i want some” is in the shop url. I got an email when I placed the order, confirmation of delivery, and an email when it arrived (so I knew before I even got home). All very slick. I’ll see how I get on with it… …In the mean time if you want to see some vintage tech, check out Maggie Philbin’s blog post on Kingswood Warren, ahead of the program on BBC Click.

There is also a two finger gesture, for “replay” – but I thought I’d keep that one out of the video .

I’ve been out buying gadgets to save on standby power. The exciting one mentioned in the video is this fellow:

It is a Standby Saver Energy Saving Unit – as seen on Dragon’s Den, apparently. As explained in the video, it shuts of the power to all of the sockets when the computer powers down. There is a version for for AV equipment too, which works off of the infrared remote control, and apparently one for use with games consoles in the works.

There was an alternative which I looked at, the Intellipanel – Desktop version, but it was a fair bit more expensive, and had things like a telephone line filter that I didn’t need.

The other device mention in the video doesn’t seem to be on-line, other than in the Maplin shop: Remote Powered Extension lead. If your plugs are more spread out, the Bye Bye Standby Energy Saving Kit might be a better alternative.

It turns out that the standby saver has a little button to turn the computer back on, which turns out to be a bonus. The PC it is wired too is tucked away under the desk, so the standby saver button acts as a remote power switch, on the desk itself and right by the keyboard. That saves reaching under the desk to switch the PC on.

The RF remote powered extension seems to be doing sterling service so far too.

One of the secrets to getting good at photography is to carry your camera everywhere, and that’s pretty much what I do. However, there are times where lugging around my trusty red rucksack with a full Digital SLR, a couple of lenses and a flash, just isn’t practical.

Then there’s the impact of whipping out a full sized SLR camera with a big lens. Seriously, last week at an event I pulled out my camera to take a picture of the speaker (I’d asked his permission before he started talking). I would probably have caused less disruption if I had drawn out a firearm and waved it about whilst shooting at the ceiling. Some people are nervous of cameras, and REALLY nervous of BIG cameras. Sometimes, small is good.

So, back to that Canon PowerShot SX200 IS. I ignored it at first, even though it was shiny-new-not-even-available-in-the-shops-yet. I was distracted by the small, sexy IXUS 100 IS - there was even a red one, what did you expect me to do?

Then I picked up the Powershot. I looked at the screen, which felt strangely like looking through the view finder of my DSLR. It is big, clear and fast. Then I fiddled with the very familiar dial on top and set it to Aperture priority mode. Ooo… Nice… Then I took a couple of shots. Ooo… Really nice.

It has got a 12 X optical zoom (equivalent to a 28-336 mm lens on a full frame camera, which is about the range I carry in the lens set with me when I’m using my DSLR). The sensor is 12 Megapixel with ISO up to 1600, and Canon’s DIGIC 4 chipset handling the image processing.

You can put the Powershot into auto mode and use it as a (very clever) point and click – it has face detection and scene detection with really good image stability – or you can twist the dial and go all Tv/Av/M and make like you have your DSLR with you, tweaking the settings to your heart’s content. The aperture is wide for a compact camera, so you can even get shall depth of field for arty portrait shots.

Here’s the clincher for me: it supports 720p HD Movie recording, complete with an HDMI output ready to plug into an HD screen. Something my current DSLR won’t do! This thing is ideal as a complement to my full bodied DSLR when I want something I can just slip in to my pocket. Very neat. It is also a nice step up for someone moving from the point and click world towards a full on digital SLR. I’ll be recommending it to a few folks.

Try the VisualDNA shop Beta:

It might not look like it, but that is a wondrous thing. It represents the next step in home hacking with the current cost meter. It is a lead which connects the current cost meter to the serial port on a lower power PC that runs a simple Perl script that records our power usage. The PC runs a script that captures the information from the current cost meter (current power used, in Watts, and temperature in ‘C) and build pretty graphs that are then published on a local web server.

Here are some of the useful resources I used to get it done:

• This original post from jibble.org: making graphs using the current cost device.
• Crouching Badger’s experiences with the USB version of the cable with links to a simple perl script.

The Jibble post got me started, although not being a PERL programmer or RRD user meant some of the “easy to make” changes weren’t actually that “easy to make”. Having learnt RRD a bit more, I’m impressed with it – great for performance monitoring of all sorts of thigns. It will take something more to move me to PERL as a programming language – PHP is as non-visual as I’m going to get. Some other pointers that helped (and give you an idea what it is all about):

• Dale Lane has done a fair bit – it was good to meet him at HomeCamp (I like Dale’s daily electricity bill too – I’ve build something similar, but taking the Kilowatt hours figure from the Current Cost Meter).
• Likewise Nicholas O’Leary has a series of posts.
• There is also a Google code repository.
• Ben Smithurst’s posts were also very helpful – a full script that updates rrd and an sqlite database too.

A slight warning: the commonly used PERL script fails when the temperature goes bellow 10′C though (since the current cost prints a leading space then, which causes the perl string matching clause to barf) – keep your current cost warm or fix up the script .

I have been amazed at the power of measuring usage in changing behaviours. Measuring really is the first step to managing. Even more excitingly, I have noticed that my gas meter is readable (via a magnetic or optical sensor) so I should be able to track that too soon – as if I’m not driving the family crazy already. Here’s a day of our electricity use (with min, max and average power):

Oh the suspense! Well managed communications though – a general note: if you are going to be late with something, let people know. Much better than letting people down. Well done Matter.

The general idea behind Matter Box is best explained by Matter themselves:

Matter is a new and innovative way for companies to talk to people by giving you real, physical stuff – things to hold in your hands, keep in your drawer, or give to your friends.

In a digital age, we want to bring companies and people together around real, physical things

I like the sentiment. As much as I am a massive on-line advocate, real physical stuff trumps the on-line world anytime. 

It isn’t easy to show in a picture, so let me list what was in the box:

• Cadbury Cranberry & Granola Bar
• BBC Audio Comedy sampler
• Original Source Orange Oil & Ginger hair and body wash
• LOVEFiLM DVD cleaning cloth and a month’s movies
• O2 sim card pack
• Pimm’s, Baileys, Bell’s & Gordon’s winter drinks pack - recipes and ‘roaring fire’ DVD
• Sampler of ‘Let Battle Commence’ by Conn Iggulden / Harper Collins.

Get yourself one of these, for a mere £20 or so:

A Wi-Fi Detecting T-Shirt

How could we have survived all this time without one? Of course, you could always put that money towards a month or two of 3G service. I still can’t seem to find a hotspot when I need one!

We will see a lot more intelligent devices as the underlying technology gets cheaper and more compact – increasingly these kind of devices can be build with a single chip. It is a much faster way of checking your email that firing up your PC to find nothing is there, apart from the usual SPAM of course!

You take the base system, then snap on the compentents you need, creating your own unique gadget in real-time. If my eldest son sees this thing, I am in big trouble, he’ll want a dozen and would have ideas for a hundred more modules! There is an SDK to develop apps and BugLabs are driving the growth of a development community around it. The APIs and connections are open, you can download the specs from their site, so anyone can create modules and applications for it.

If you want to see more, here are a set of videos of Scoble interviewing BugLabs CEO and the marketing guy (is than a new industry job title?)

• Video one, introduction.
• Video two, final shipping plastic.
• Video three, open hardware.

I can see how you could end up with a few hundred of these around the house doing everything from security to environmental monitoring.  Their viral videos and blog are quite cool too!
