Servo

Servo

I have a small servo lying around in my partsbin. Bought it from dx.com a few years ago and when I stumbled on the subject of servo testers I was tempted to build just that, a servo tester.

 

I decided to build the servo tester as described in http://www.instructables.com/id/Simple-Servo-Tester/. It’s describing the build of the project that was designed by W9GFO. You can get a kit from Gadget Gangster.

There appears to be no eagle schematic or single sided board layout out there so I share mine.

I created a single sided board layout for it.

I used a 3 AA 4.5 Volt battery pack to power it and… that does not work.

Left it for a week giving it some thought and finally hooked it up to an adjustable power supply and gave it 6 Volt. There, it worked like a charm.

Mental note: when it say 4.8 Volt means that 4.5 Volt does not work. ๐Ÿ˜‰
