September 28th 2023: I can't make the linear actuator move precisely
Log from Automatic Moving Cricket Wicket
It was dumb to use a DC motor for this project. I should have just ponied up the resources for a high speed stepper. My plan was to attach a rotary encoder to the DC motor to accurately measure the number of rotations. This is not easy....First, I tried...

Log from All About Laptop Keyboard Reuse
A laptop keyboard is a diode-less key matrix. Its keys are distributed in a way that you can press the most important key combinations at once, despite the lack of diodes - to the point where some rows only contain one or two keys. Often, there's also...
