Late last year, [matseng] set up an interesting challenge for himself: design a new PCB every week, send it off to a fab house, and build a new project. It’s a grueling endeavor, but some of these projects are actually very useful and cool. One of the best so far is the TraId – a board that identifies a transistor type and pinout with a nice LED interface.
This build was partly inspired by Dangerous Prototypes’ Part Ninja, a board that determines the pinouts and values of transistors, resistors, caps, and diodes. The TraId is a much more cut down version usable only for transistors, displaying the orientation of the pins and type of transistor on a set of 8 LEDs.
Although the design is very sparse, we could imagine something like this being very useful in a hackerspace, lab, or anywhere else the gremlins of chaos come to reorganize parts drawers. If you’d like to build your own, all the required files are up on the gits.
