What if rotary encoder does not click

I have got a function generator and power supply for $30 total.

The generator works great, but power supply was kind of weird. It was only adjustable when I did it really, really slowly. Once I tried to go faster, it was jumping to 1 then back to 0 then to 1 then back to 0. Yes, it was usable in general, but for a impatient guy like me it was a torture.

So I took it apart. There was a rotary encoder that did not click. It was just rotating smoothly like a potentiometer. This is clearly not what rotary encoder supposed to do. I decided, that I will likely not be able to repair it because some tiny part is likely broken, so I should buy a new one on ebay. But I decided to check it out first, so I opened it. This is the top part.

Gear Tree

GearTree

Gears were designed (well, generated by a plug-in) in Inkscape and milled with CNC.

What is the purpose of this project?

Xenia needed it for school. No, not for science. It is for English writing, believe me or not.
