I built a simple Zener diode tester using a 9V battery, an MT3608 boost converter, a small on/off switch, and a 1kΩ resistor connected to two multimeter probes. This device can measure the breakdown voltage of Zener diodes, determine the appropriate voltage to light up different colors of LEDs, and even test SMD LEDs in energy-saving bulbs by identifying the voltage required to power them up!
