BMC39.Step Rhythm Sequencer
This is a step sequencer module. It has an internal clock with it's own output as well as two programmable output channels. It has EEPROM save/load function (saves patterns after powering down), and a range of 2 to 32 steps. LEDs, Pots, and Switches are all mounted to the PCB to minimize wiring while allowing for 1/4" and 1/8" jacks to be used with the same PCB For more information, check out this PDF file.
Boards are available now. Price for 1 board and 1 preprogrammed PIC $20.
There are unfinished aluminum Eurorack panels available for this project. They are $9 each. For more information on my panels, check this page. If you'd like to drill your own, here's the template that I use, print it out at 300dpi
