Warning: NSFW language. So, Autodesk bought Eagle. This in and of itself would not necessarily be bad news – Eagle has been in need of some improvements for some time, and occasionally, when a bigger company assimilates a smaller company … Continue reading
The GPIO (General Purpose Input Output) pins are the pins of a microcontroller (or other device) that can connect the device to the rest of the world, without having a particular dedicated function. In contrast to pins dedicated to a … Continue reading
Introduction This text is a quick post that should give a quick explanation on (overdetermined) systems of linear equations, particularly their matrix form. It is for an upcoming article that deals quite a lot with these systems. Warning: Please note … Continue reading
I love going to the flea market – you find all sorts of fun stuff, bargains, trash and the occasional treasure that is being sold for next to nothing. This posts fits into the ‘fun stuff’ area – while at … Continue reading
Recently I got a L110 resistance decade box made by METRA Blansko, in former Czechoslovakia. Unfortunately something was rattling inside, so I had a quick look inside to remove the offending part – it was a small metal nut that … Continue reading
While on a buying frenzy at a local radioamatuer gettogether (Holice 2014) I saw an interesting looking PCB – apparently taken from some kind of older HP system, it had some very nice oscillators (500, 525, 100, 126 MHz), some … Continue reading
On this page I would like to publish some thoughts, sayings, rules of thumbs and wise things that I’ve come to observe during my few years of experience in the field of embedded systems design (and life in general). If … Continue reading
I recently started (again) to poke into FPGA devices. I remembered the most annoying thing about that development – it took so damn long to compile. But, when one takes into account how much the compiler (implementer, mapper, optimizer, whatever) … Continue reading
There are two basic ways you can give out information on your products: A comprehensive, simple, publicly available website, complete with all of the information the potential customer might need, support software (if applicable) freely available and easily available pricing … Continue reading
