My mate's Raspberry PI is somewhat faulty and crashes once it gets warm or the likes

so I decided to use my FLIR i7(new toy spoiler )  to video it during booting XBMC,

then again playing some videos off the USB stick. note that during all of this the USB/NIC

chip actually is hotter than the CPU/GPU doing all the heavy lifting ...very odd!




Whilst still on the historical bent here's a short  video I took of the WITCH/Harwell Dekatron  which is the oldest working stored program computer.

Again you can visit it at The National Museum of Computing at Bletchley Park.


I just love the way the actual value in the Dekatrons can be read directly from their fronts, you can even see the data "spinning" from 20 feet away









This is the tour around Bletchley Park and took in all the old school Crypto stuff including a trip around  The National Meuseum of Computing.

There are 100's of small exhibits there but one ofo the best is the  Colossus the worlds first electronic computer


Glowing valves, the hum of the paper tape feed all add to the excitement as well as a talk delivered by a staff member



Hope you enjoy the vid.

Shropshire LUG carry the message about Linux and Open Source to the public again this September

The group has a table to show Linux, open source software and  hardware to radio amateurs and others attending the Telford Hamfest  organised by Telford and District Amateur Radio Society.

Members come along and support us and anyone interesed come along and say hi.

We hope to have radio related setup (based on HamOS Linux distro)  connected to a radio to transmit and receive contacts, also a Reprap  owned by Chris G and also decoding systems to show weather satellite  imagery and possibly some Raspberry Pi things.

More informaiton soon – but have a look at;



Don't think Dave Jones really needs me pushing his blog (Excellent BTW) but I particularly liked his

"First of a series" Primer on FPGA technologies. Obviously he hasn't gone into too much detail or

vendor specific stuff but it's a great start non the less.


I'm sure many of us here are getting long enough in the tooth that we need to move PCBs and other parts away from you in order to focus on them.

Conversely or should I say perversely the world is intent in puting millions of components on boards that look like dust and writing that is in some

sub nano metre font. Connectors are little better at least when they are designed for humans, get the "robot only" ones then you are once again in the same senario.


My solution for this is simple, take photos, yes it is that simple a good macro function on your compact or better still a macro lens on your DSLR and you can once

again see clearly.

Don't be a hero strugling with a crappy magnifier take a photo zoom it up as much as you need, it's also good as a memory aid or to add pizaz to your reviews or at least fill some space up when you are

finding it tough to fill the page ... Good luck.

A Mere 499990 watts less than the monster I mentioned a bit a go but proabably a bit easier to actually construct






Fun idea technology with a social context.  From, I suppose the legality all depends on your

Licencing situation.

Parallella is the $99  Eval board for Adapteva's highly parallel computing chip that they have been recently funding under kickstarter.

The good news is that they have reached critical and even starting to take orders for non-kickstarters at the same $99 price point.

There is even a $199 version for the speed fanatics who want the Zynq 7030 FPGA from Xilinx  rather than the 7020.



Either one is great value and looks like just the thing to experiment in the field of highly paraell computing and or that rather cool Zynq CPU.


By the way i've forked out and ordered one so watch this space

Had this in my "to  watch queue" for a while figured that this well put together video on Pre-war Power RF would

be interesting to folks who wanted to see what "plumbing" in the day really looked like and how it pushed the envelope

of technology at the time and really even now for most of us!
