Hi, Here is my suggestion to turn your oscilloscope into a clock with a PIC a 4 resistors : http://www.micro-examples.com/public/microex-navig/doc/082-pic-oscillo-clock I'm opened to your destructive comments :) Bruno

Somewhere on the world-wide-interweb is a 50's era article that shows how to synthesize some very nicely rendered digits onto a X-Y display using sine/cosine waves and harmonics. Tim.

(Granted, someone like Joerg might suggest that the ratio of how often you use a 2465B to a digital 'scope tells you something about how good you are at circuit troubleshooting... :-) )

I should have named the topic "how to turn your expensive power supply into carbon". Schematic has been corrected ;-) Thanks ! Bruno

[scuttles off to dig out code and see if it is feasible to translate to PIC asm]
