Hey all, Here's my very simple guitar tuner board. Schematic: http://postimage.org/image/yqrtiyh0/ Unrouted PCB: http://postimage.org/image/yqth2ays/ Routed PCB: http://postimage.org/image/yqq5zlz8/ I'm planning to get it made with DorkbotPDX. $5/sq in and you get 3 copies of the board. The board is powered from 3V (2 x 1.5V alkalines), has 2 push buttons for picking string/other function, has a slide switch for power, crystal with capacitors, ICSP header, 6 surface mount LEDs for staus/string choice, two high brightness LEDs for oscillating. Just realized - those high brightness LEDs take 30mA, but the PIC can't provide 30mA on each pin. I'll probably stick a couple of small BJTs on there. Maybe two MMBT2222 type. --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
