Low-Cost USB Oscilloscope

[malc-c]

Here is a very simple one I found that uses a 18F4550.

They also have some more complex models as well but this one includes everything and its free.

OK downloaded the exe, browsed the files etc... but there is no scematic. It states on the website

Project of digital storage oscilloscope, hardware is just PIC18F4550 and few passive components.

Browsing the site there is an updated miniscope2 which shows a PCB which has a bit more than a few descrete components but the chips look too small to be a 18F4550 (assuming its a 40 pin device)



Do you still have the schematic and can you post it here or provide a link to where it can be downloaded from ?

EDIT - just re-read the bit about the ver2 -Based on AT91SAM7S64 microcontroller. - Doh !
