Here are some projects I've built over the years:

• VidiPIC
  An NTSC video frame generator based on PIC18F2xxx controllers.
• VegiPIC
  A simple controller to switch valves in a VO converted vehicle.
• VelociPIC
  An elementary direction and step pulse generator.
• PICStep
  A stepper motor driver based on the linistepper open source driver.
• LockPIC
  A simple PCB originally meant for a keypad controlled lock.
• DimPIC
  My introduction to PICs to create a PWM light dimmer.
• BootPIC
  A serial bootloader for PIC18 devices.
• GPICode
  A G-Code interpreter running on a PIC18.
• PICPlot
  A PIC24 interfaced to an old drum plotter.

Great projects by others:

• MaxiMite
  A very impressive single chip BASIC computer by Geoff Graham based on a PIC32.
