Graphic LCD display 28th August 2005

I've recently bought online a large quantity of displays and paid a very good price for the lot. The displays came "as is" with absolutely no documentation or hint from the web. The company that originally produced them was out of business and their website was gone. I hopped that I will be able to reverse engineer these displays and my work paid off.

JTAG interface schematics 3rd March 2006

JTAG interfaces are a mess. They've managed to turn a standard into zillinons of different implementations. These schematics might help someone build their own (universal) JTAG programmer. JTAG schematics

Reverse engineering the radar detector Beltronics Euro 550 29th September 2010

My motivation for this R.E. project was that after several years of using my Beltronics radar detector it started displaing the following error code ?LO3 CAL? ?MARKERS?. Its warrany was well expired and I could not have it serviced here in Europe. I've also bought a cheap Whistler XTR-330 detector to replace my Beltronics for the time I was sorting this error out and I've regreted the buy the same day. The Whistler is more like a LED blinking / noise making device than a radar detector. Out of curiosity I've taken apart the Whistler too and you can spot right away the cheap chinese electronics.

Galep4 DIL40 to TSOP48 programming adapter 4th September 2014

I own a Galep4 programmer and I wanted to read out the content of an Intel 28F640B3 NOR memory. Unfortunately this programmer only has a 40 pin DIL socket any my part was a TSOP48. Conitec (maker of Galep programmers) provides such an adapter for an extortion price of 300 Euros. For this price you can get the Xeltek 610P (which is in the same category as the Galep5 with 48 universal pins and very well supported) and a TSOP48 to DIL48 adapter . In fact I've just ordered these two for my future needs but to get the memory content out I've quickly bread-boarded an equivalent adapter.
