Led Tester With Brightness Control

After some weeks without any free time for new projects, i give you my new led tester with brightness control.

From time to time i need to test some leds and before i had a battery with a resistor hanging on to teste them.

This is by far the worst solution to have on my workbench.

Therefore i decided to make this led tester to include in my workbench’s tools and it is capable of changing the brightness and connect bicolor leds. [via]
