TraID the automated transistor type and pinout identifier

Nifty

Matseng put together a nifty tool that can quickly identify both the transistor type, and the correct pin out.  We posted a method earlier on how to determine these characteristics manually, but where’s the fun in that ?  Part of his self set goal of making a Project A Week, this is his 22nd week project.

His design uses a PIC16LF1503 microcontroller and is powered by a CR2032 coin cell battery.  It uses LEDs and silk-screen markings to show you the output.  On the PCB there are holes for common transistor configurations such as to-92, to-18 and to-220 that you can insert to be identified.  The part is given a voltage in different configurations and read back using the PIC’s ADC.

Source code and schematic are provided on his post to the Dangerous Prototype’s forums.
