turn your expensive oscilloscope into a $5 clock

Hi,

Here is my suggestion to turn your oscilloscope into a clock with a PIC a 4 
resistors :

I'm opened to your destructive comments :)

I remember hacking 6800 assembly code as a kid and tweaking R's and
C's in my ramp generator until I had spelled out my name on the scope
screen :-).

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.

Your schematic has +5v connected directly to GND.

The project itself is cool, though.

Very nice... good use for that old Tek 2465B when you're not using it for Real 
Work!  (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... :-) )

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

Thanks !

Where?

Ah.

Reminds me of a late '70s Byte project for Space War (gravity and 
everything!) on a 'scope using an 8080.
[scuttles off to dig out code and see if it is feasible to translate to PIC 
asm]

Well done.. Nice U Tube Video support

Fun is good
