content: You're going to get ripped a new one not being bothered to export an image. Lots of folks here don't have Eagle installed and won't be bothered to just to help you.I'm a nice guy, so...Edit: forgot to change background color to white.

content: This is probably that well-known component tester designed by Karl-Heinz Kübbeler. Here you can find the firmware.http://www.avrtester.tode.cz/index.php?p=firmwareAuthor's web:http://www.mikrocontroller.net/articles/AVR_TransistortesterHere is a main thread.https://www.eevblog.com/forum/testgear/$20-lcr-esr-transistor-checker-project/360/

content: That LM339 PWM circuit is IMHO rather useless. The backlight level can be set to maximum always.

content: That circuit looks very familiar ;-) You'll find the source code athttp://www.mikrocontroller.net/svnbrowser/transistortester/Software/('trunk' is the current k-firmware under development and 'Markus' contains the m-firmwares).

content: Quote from: Hydrawerk on April 23, 2014, 06:36:55 pmIt's nice to be able to set the backlight based on your environment. But you're not forced to build the tester with the PWM circuitry if you don't like it ;-)
