A PIC based micro oscilloscope.

I used the laser printer toner transfer method of PCB fabrication. I mounted all of my components vertically on the board to minimize space requirements.

I made a few small changes to the circuit, the main one being to accommodate using an oscillator instead of a simple crystal; I was unable to find a 27MHz crystal locally.

This is a great little project that will yield a useful tool for your bench. The total cost of components is under $10. The only downside aside from the low sampling rate is the fact that even when overclocked to 27MHz, the PIC is unable to generate an NTSC signal. As such, you will need to have a TV capable of displaying a PAL signal to make use of this device.
