Zener Diode Checker
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.
