Reconstructing schematic from two layer PCB
(1/3) > >>
bigmac:
So... i've got myself into a bit of a project.
Quick story.
I bought an electric car, a Kewet El-Jet 4 from 1995. Not working. Turned out it had the wrong type of computer installed.
So.. I sourced another El-Jet 4 in order to get the computer.

My plan is to copy the computer.

so i ripped the computer out, photographed it, documented all of the parts, desoldered, scanned, retraced in sprint layout....

but now i'm kinda stuck. I can export gerbers from Sprint layout, but to where? What would be the best route here? (pun intended) thank you
mc172:
Why do you need the schematic in order to make a copy? If you've copied the layout and know all of the component values, that's all you need.
Rerouter:
kicad can import the gerbers and allow you to edit them, and I suspect rebuild into a schematic + project, I just have not used it in this manner before,
digsys:
If you have all the board details, why not source a spare board or two off ebay / alibaba / aliexpress etc etc
I've found heaps of rare boards for various project I do, rarely failed to find one. Or do you intend to mass produce them?
mikerj:
Easy-PC can apparently do this, though it's a pretty expensive licence for a hobbyist.

If he's also reverse engineering the firmware then a schematic is going to be pretty essential to understand the operation of the board and debug it.
