Experimental Zener diode tester

Dilshan has published a new build: Automatic Zener diode tester is capable of identifying Zener diodes up to 27.5V. Apart from that, it can be used to recognize leads of the diodes/Zeners and detect damaged diodes. This tester is designed using well-known ICs such as MC34063 and PIC16F88. This unit provides approximately 5% to 15% […]
