Servo tester MOD upgrade for Mike B

10th October 2025

Mike B’s new project requires a few servos, the tester wasn’t functioning properly so said id have a look as well as check on the mini servo he had.

I 3D printed off a slightly modified housing, his tester circuit board differs from my version so the hole positions didn’t match up properly.

I had already made myself a version for testing on my bench, plugging in to a 12v power supply. The voltage regulator was adjusted down to 6v max for testing and a digital voltage gauge was installed.
