Next step in my current electronics project, after idea and schematics, is prototyping. Here is working prototype assembled on breadboard using lab equipment (like power supply etc). In top-left corner is zero-level cross detector, it converts any periodic signal with amplitude from 1 to 5V into square signal with 0 to 5V amplitude, pretty much digital one.
In bottom right corner Atmel’s ATTiny 2313 that measures frequency of this signal and shows it on display.
All of old. Nothing else ever. Ever tried. Ever failed. No matter. Try again. Fail again. Fail better.
Hard drive on on of our client’s server went bad so we replaced it. Being curious, I teared it apart just see what’s inside. This is top view before operation. It needed torques not regular screwdriver.
