AVR transistor tester build

Monday, January 23rd, 2012

Mick received his boards for the AVR transistor tester (machine translation) and was quick to assemble them. His board was designed to the exact dimensions of a 2X16 LCD screen. He did have some issues with the silk screen, but all in all we think his boards are awesome. Via...

Teensy 2.0 based transistor tester

Friday, December 30th, 2011

Wingnut decided to port the AVR transistor tester to his Teensy 2.0 board. The transistor tester is a tool for identifying and measuring common discrete semiconductors and passive devices. I decided to port the component tester (freely using Google Translate to get some sense of the comments) as my first...

Arhi’s transitor tester built into a case

Tuesday, December 27th, 2011

[embed][/embed] Arhi built a transistor tester, a tool that recognizes and measures most common semiconductors. We've been following this project closely for the past week or so. After building a perf-board version, he made this version to put in a case. Check out the video of it in operation above....

Transistor tester breadboard build

Friday, December 16th, 2011

Arhi had some free time so he decided to test out the transistor tester. He built it on a breadboard, and quickly got it running. I was waiting for some app to compile for past few hours so I breadboarded this baby. Works like a charm :D ... I had...
