PIC 16C84

Since I started programming the PIC 16C84 ten years ago I started various projects. The PIC is a nice processor. It is easy to use, small and fast.
Ok, it is easy to use. There are smaller processors and faster processors, but a definite pro is that the PIC can drive up to 100 mA at the ports. This is enough for small motors or loud speakers. Here you will find my favorite projects.

• The morser is a morse code generator. It can output a call for a morse QSO at different speeds. You can program your call (will be saved in the eeprom) and set different endings.
• The plotter is a digital positioning unit for acurators. The plan was to build a 3D plotter. As with many projects I start the software works fine but the mechanic is crap.
• Razorback is a project to build a small remote controlled tank.
• Soundmodul is a modul for playing sounds with a remote controlled model ship. There are many different sounds even a duck program.
• Star is a small program for displaying moving patterns on a chrismas star. The star should display a infinite (about 2¹⁶) number of different moving patterns.

Update: Since a year I am now using an Atmel processor instead of the PIC. It can be programmed in C with open source tools. It has a lot more goodies like A/D converters and serial bus components. And I just need a parallel cable to program it (which you can build on your own) The only downside is the higher price which is not relevant if you just use a couple of them.
