I desperately needed some through ports for devices I have that have only in and out ports. So this easy project was done in a single worknight (after putting kids to sleep, 2 hours at most) It is no compicated design. You just have to get the midi input (using the optocoupler like all midi stuff [...] This is how fractalSynth looks like: And this is how it sounds (a little tape delay added) I had once stumbled upon Catweazle’s fractal synth. In the circuit benders forum it seemed that the project had come to a halt. But recently I realized that it was going on elsewhere.! Here.Also, the files can be found in [...] midi interface (a little deviation from schematics here since I didn’t have a P900 or 4N25 optocoupler at hand and used a 6N138/9) The (typical) power supply. 5v with 7805 This is a serial communications module (using the UART that exists inside the PIC 18Fxxx, It just changes Voltage levels so your 5v microchip, doesnt get fried by the serial’s +-9V This is a simple 7805 on a perfboard. Giving stable 5v to your (my) test circuits and breadboard projects.. I recently made a 3.3 V [...] An old project of mine (6-12-2008) was to have a counter run through a series of voltages and make a waveform out of it. There is a pulse generator and a counter at the bottom part of the breadboard and decoders at the top. It never worked right so it was dropped. I tried [...] |
