Nice! Too bad the USPTO granted someone a patent on this approach (7352340).

An optical mouse tracks relative movement, so error will accumulate over time. Also, if rotation of the mouse isn’t constrained somehow, there will be additional error. You can mitigate the second issue by using two optical mice, but I felt it was easier just to do absolute position tracking with a camera.

Why not using an optical mouse instead of a cam?

Comment on Physical Keygen: Duplicating House Keys on a 3D Printer by Anonymous

Very cool. Though that appears to have been a design show of a concept (a very nice one), printed on a high-end 3d printer. This is a working key printed by a MakerBot, which is an impressive feat.

I verified it works with bi-spy-wire. The pinout of the header is:
TDI TST RST GND

you can hook up the last 3 to a launchpad and run mspdebug. I’m working on getting the firmware off it (should be easy as mine is a MSP430G2111, with 1kb flash).

Just opened mine up, have a launchpad, so i’m going to see if the JTAG emulator on the launchpad will work with this chip. If it does, I will get the firmware and decompile, hopefully getting some info on how this thing works, since mine seems to have cut out the multiplexer for what looks like a few transistors.

Fantastic and thanks for sharing! Don’t have my 3d printer yet, but will be using this as soon as its done to visualize the object on the print bed before I start.

Thanks again!

I believe those tabs were spot welded to the cell.
