Prototype progressing

I started to build first prototype of device and it is progressing well. Curently power supply module is under testing. CPU card and IO modules are also ready and waiting testing. During prototyping i changed design radically. All these changes are made to lower overal cost of programmer and make it available for more people. Now programmer uses 5v volt instead of 3.3 and USB connection changed to serial. Power supply will be build from well available parts(lm317 based design)
I will update schematics when i have done some basic tests to device. I have also started to code PC side of software. PC side software will be object oriented C++ design.
