Ever wondered how much heat's been produced by your equipment? Takes a look at my  Sterling Engine busily spinning as a result of the heat from an External drive running on my desk !   Pitty there isn't much you can do that's actually usefull with this heat but it's fun any way! ...
A friend and I got talking about the speach sythesiser ICs used in music such as Kraftwerk this turned out to be the SSI/Votrax SC02 Now the '02 was extremely hard to get hold of but th e SC01 was indeed available from Ebay, now that's an extremely dangerous thing and needless to say it's made it's way from the US to my sticky paws!     The whole story of this chip is quite interesting  but I was more interested in getting  this running on some modern micro, fortunate ...
I've just got this pre-release board from Magnus. Yes it's yet another FPGA board, but where as most have some rather anoying lack of "whatever device connection you needed" it's simple and well thought out with AUDIO/USB/HDMIand micro SD with 64MB of RAM . Mine came pre imaged with an entire linux machine and the boot Image for it !!!     Any way I got half way through writing this to find that "Alex the Kidd" got there first so go take a look  on his blog too ...
I've been watching some of Electronics Blogs and during the manditory tear down they always came up against the laser etched chip. All very anoying but apparently not as effective as it could be if you have a good idea from the rest of the design you can have a good punt on the chip's true identity.   Any way I decide to have a go at removing the markings from a poor victim who shall remain anonymous   ...
The classic way of teaching folk the 101 of microcontrollers is to get a few LED's to flash. The code is simple the result obvious and we are all strangely impressed by this "hello World"   In that vein I decided  to make a fun object whic is nothing but lights in this case an Acrylic Space Ship Lit up using LED Light ropes.Here we have programmed an Arduino Nano on a Breadboard to go through the test sequences.     If you are interested in owning one of these then ...
This chap obviously has something against our Vending machine overloards and as spent an inordinate amount of time designing a Robot (or remote control device if you prefer) that can sit inside a vending machine and lower drinks down the shoot.     Obviously what he's doing is illigal but the wonderful way he's doing sort of makes up for all that petty Law stuff. ...

Eagle on Fedora 18

Posted by Problemchild Top Member Mar 25, 2013
Ok needed to get going on actually installing the Eagle 6.4 on my Fedora 18 machine. Firstly after the install comes the substantial number of updates (Get these or be forever a Slacker!! )   Imediately I have a couple of problems here, firstly the Linux version is really new and liibs are equally so, secondly I'm installing this 32 bit application on my 64 bit system, so not only do I need a set of support libraries but also the 32 bit versions. Fortunately these all exist and some of ...
Just been popping through the vast number of FOSDEM videos and found this little gem.   if you are a member of an Open Source project encourage those non technical Jane's and Joes's They bring with them the ability to comunicate to  the world at large with out the aid to technical Jargon or assuming knowledge or the ever patronising RTFM!!!!   Well worth the 40 odd mins!     ...
The last board layout I did in cad must be 20 years ago and although I get the general idea I'm sure I that in parctice I know Jack(tm) !!   I've been promising to do some designs but talk is cheap so I got a licence for the lattest and greatest Eagle 6.4 (thanks Pat)!!   Over the next few months I will be writing on my findings ..Eagle experts expect loads of NOOB questions.     I have a few projects of my own which simply need to be done over the next few months so there ...

Last week we had the opportunity to  talk to Alex of Space Gambit in of all places Shrewsbury High street. The upshot is that we have been asked to come with a proposal for a Space Related Project. The project can be anything space related,the project will be judged on it’s merits and the budget required (Up to 20K$). As well as technical merit, an educational element is important also the project must also be open source! Fellow Space Cadets get your thinking caps (or should that be ...

Posted by Problemchild Top Member Mar 21, 2013
I was fortunate enough to attend this year’s FOSDEM event in Brussels early this Feb’.   It’ s an annual event started in 2001 and although aimed at developers or others involved in Open Source projects it’s open to anyone who has an interest in open source software.   Held in the University of Brussels it’s simply huge with some 7000 attendees and 486 speakers for 487 sessions and 40 tracks it simply takes over the campus for the weekend, many of these ...
