PIC 12/16/18/ds30 programming support for the Bus Pirate is progressing. Sean Nelson, a regular contributor to the Bus Pirate project, submitted a patch that adds serial port support to usbpicprog. The Linux patch compiles, but the Windows port still has some bugs.

The picture shows our prototype 13volt power supply for the PIC programmer. It’s a simple SMPS that can boost the input voltage to anything below 13volts. Our tests showed an unregulated output of over 120volts, but the final supply includes a feedback loop to set the output voltage level and a 13volt zener clamp to protect the PIC from damage.
