Hi,

Some older non PC computers have A/D built into joystick ports or sound
capture ports. The Acorn BBC and Amiga computers I think. You could look at
getting an old one cheap. They can be programmed in basic for the graphics
etc.

Or just buy a used audio scope. 10Mhz 1 Channel.


For most A/D joystick type ports, the are mostly an R/C pulse
generator, with the R component supplied by the pot in the joystick.
Hardware or software would time the width of the pulse, and report
that to the user program.

There are some that use your sound capture card

It would be helpful for some of my electronic projects to have a simple
oscilloscope, and I'm thinking the easiest thing there would be to have
some
sort of ADC that could be picked up and displayed by some Windows
software.
I've seen various commercial products to do this, but they tend to be
much
faster than I need (100 MHz) and much more than I want to spend ($200+).

I don't even need sophisticated software, I'm perfectly happy (for now
at
least) with a system that dropped its results into a text file that I
could
import into Excel when I wanted to see pretty graphs.

Has anybody seen such a beast?

Thanks!
Chris
