PIC programming is useful as it allows you to build electronic hardware and to implement software into the
hardware at little cost and relatively easily.
Programmer for PIC 16C84, 16F84, 16F627, 16F628
Searching the internet I have been unable to find a programmer as simple as this one
which was built from a schematic ages ago, if anyone does know the
source then they will be acknoledged as the source is still unknown. This
programmer is the simplest I have seen utilising no external power surply and
only 6 components. It connects to the computers serial port.
Note: It appears this design is simular to the COM84 Programmer.

Maplins Total Cost: ~95p + a socket and some board
- 2x Resistor 4.7K
- 1x Resistor 10K
- 1x Capacitor Electrolytic 100uF
- 1x 5v Voltage Regulator LM7805
- 1x Diode (Pretty Much Any Diode)
A possible PCB solution for this is provided below, I have not yet built this as I
still use a stripboard based version which I believe is equal to and possibly smaller in size.
