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 |

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? |

Easy-PC can apparently do this, though it's a pretty expensive licence for a hobbyist. --- Quote from: mc172 on January 03, 2020, 10:57:18 am ---Why do you need the schematic in order to make a copy?
