Zener Diode Checker

By on May 4, 2009

Remember few month ago there was a photo of me posting with a guy from Iran in a Hotel? For your information i went to the hotel to deliver a Blue Ring Tester for him. Recently he emailed me about his success in  building the zener diode checker and have fully tested the checker and i was glad that he allows me to share the photo with my blog readers. Below is the photo of his zener diode checker. If you would like to have this zener diode checker circuit please sign up at http://www.electronicrepairguide.com/electronic-repair-newsletter.html to get one and read other repair articles as well.
