Build a powerful backlight, LED strip and zener tester!
Let's build an excellent LED backlight tester and LED strips, which also tests and identifies the zener voltage of any diode, etc. Generating voltages close to 300V! A detailed assembly, with schematic and component list, all simple and easy to find. Very useful on the repair bench and projects. More details in this Youtube video:
