Fixing a PM5132 function generator with the Part Ninja

JanW has used the Part Ninja to rescue a PM5132 function generator: Today I put the Part Ninja to good use, it came in handy when I was troubleshooting an old Philips PM5132 function generator. While I was working on a project I wanted to take a break and switched the signal gen off, later […]

Part Ninja built on perfboard

JanW built a Part Ninja on perfboard. He used a DIP cased microcontroller and through hole parts. He also replaced the 2.5V voltage reference with the similarly specced  LM385-2.5. The connections were made with enamelled copper wire AWG 28. The lacquer is burned off by tinning it with a very hot soldering iron (400 ° […]

Transistor tester powerd from 2 AA batteries

Ferdinand added a dc/dc converter circuit to the transistor tester, allowing it to be powered from 2 AA batteries instead of a single 9volt. This project is similar to our Part Ninja, it’s designed to test various electronic components like transistors, diodes, resistors, etc, and display their pin out and basic specifications. I built my […]

Part Ninja semiconductor tester demo firmware available

A demo firmware for the Part Ninja is available in the forum. The Part Ninja detects they key properties of semiconductors. It can identify transistors, FETs, resistors, diodes, capacitors, and thier pinouts. It also makes a rough estimate of key values like current gain (hFE) for BJT transistors, or the gate threshold voltage for FETs. […]

3D Model: Part Ninja v1a

Our latest 3D model is the Part Ninja electronic component testing tool. It identifies electronic components like transistors and FETs, determines the pinout, and measures basic specifications. Several SMD footprints are included so surface mount parts can be tested too. Check out our tutorial on how to build 3D models from Cadsoft Eagle board files, […]
