PlingPlong – A portable synth

Posted on Thursday, October 31st, 2013 in project logs by DP

PCB-r1 Another cool project by Mats the PlingPlong, a two octave touch keyboard with four channel polyphonic synth:

This is a small (10x20cm 4×8″) portable battery-operated synth with a two octave touch keyboard and four voice polyphonic digital sound. I’m using two microcontrollers on the board – a Microchip PIC18F44K22 for the user interface and a Atmel ATMEGA328 for the sound generation. The PIC18 is using the internal CMTU module for capacitively sensing the 24 touch keys. It is also in charge of scanning the 15 tactile buttons, refreshing the 15 status LEDs and the 7-segment displays, and polling the Rotary Encoder.

Files available at github.

    This needs a link to the forum post, didn’t realise there was one!

  • Drone: So these go for around $330 USD and NO published calibration procedure online or otherwise? Given what's inside - I don't think I'll be considering...
  • Pekka Akselin: This is ridiculous!? :-) We are back at 256(!) byte EPROMs that needed multiple, a handful, of voltages to run! :-(
  • KH: Let's try a back-of-envelope calc balancing energies. From MCP1700 datasheet, there are graphs for a 200mA load step. Estimate the energy shortfall as 12uJ. Say...
  • Daniel: It's been a week and my comment is still awaiting moderation. Apparently the CIA doesn't want their involvement known?
  • KH: Agree, so okay, I guess he must have learned from somewhere. 100nF and 1000uF is so far apart, that was jarring; it's more magic incantation...
