Subject description: New module/kit I've designed
Reply with quote  Mark this post and the followings unread

Hey ya'll. I got this prototype up and working and wanted to share it with folks. I've made a youtube video that shows a simple patch and I explain how this module works.

http://www.youtube.com/watch?v=GwvNfc9L-t4&feature=youtu.be

In a nutshell, this looks at your input voltage, converts it into a number, then looks that number up on a data table and turns a +5V output on if the table tells it to. It does this 4 times, for 4 different outputs. There are attenuation and offset knobs for conditioning the input signal, write/erase buttons for writing the "on/off" tables, and save/load and bank select switches for saving your tables to the internal EEPROM.

The write/erase buttons could also be replaced by input jacks so you're rhythm generating devices could write the tables. The board has euro/motm power connector pads. The board has 2 pc mounted pots, and it also has 4 mounting holes so people can feel free to create their own layout. I am going to try to offer a Eurorack front panel for this as well.

I will be writing build documentation for this soon. I'll have boards/PICs to offer for this next month, and a set will be $20 plus postage.

I'm not sure if anyone on here didn't see this on Muffs forum, but I now have boards for this. $20 gets a PCB and a pre programmed PIC.

All build documentation/mouser shopping cart/youtube demos are at www.bartonmusicalcircuits.com and you can e-mail or PM me if you're interested.
