You’re right, but I don’t want to solder 2k wires to things. Last time I “professionally” reverse engineered a board we sent it out to get a CT scan of it, and got delivered a self executing program which contained a point cloud of data and an interface to extract surfaces, adjust the histogram (to make features visible) etc.
I’d take a handful of automated probes in a 3D printer chassis, and some vision/registration/classical computer vision algorithms.
This type of thing already exists but I’d rather have an open source one.
- bsder 3y ago> This type of thing already exists but I’d rather have an open source one Is it possible to make an open-source X-ray machine to do this kind of CT scan? It really seems like it ought to be, but I don't know enough about the source and the CCD detectors to think about how to assemble it.
- ooterness 3y agoWell, step one would be to reverse-engineer an existing CT scanner. But to do that, you'd need a CT scan of the boards in the CT scanner...
- bsder 3y agoNot really. The big question is how to get an X-ray source with enough energy to penetrate metals and a detector with enough resolution. Everything else can be cheap.
- CamperBob2 3y agoCan't find it at the moment, but someone did in fact create a passable homebrew CT scanner based on a small Faxitron medical-specimen X-ray machine of the sort that can be commonly found on eBay. Edit: found it ( http://www.rtftechnologies.org/physics/faxitron-DX50-CT-scan.html http://www.rtftechnologies.org/physics/faxitron-DX50-CT-scan... ) These machines are good for up to 8-10 layers of 1-oz copper.
- analognoise 3y agoI mean, we buy them and start learning? Famous last words: how hard could it be?
