    Producing polyphonic melodies with Pic??

    i get the circuit from cypress FAE. since the mcu contains the analog function i needed for the piano, i do not have to worry about the "whole" circuit. as a matter of fact, i only need to put serveral c and r onto the board. i believe you can use pic or other general purpose mcu. what you need...

    circuits and pcb for videoCapture via RS232 or Paralele port

    in my opinion, the interface to host will depend on what application you are targeting. if you only want real time image capturing to your PC, you definitely need a fast comm. link. Basically, the speed of the data link must be greater than frame resolution*frame size*frame rate, of course, plus...
