Here’s a really cool DIY that shows you how to make a tilt measuring inclinometer. I do highly like how Nicholas Kwan didn’t use an accelerometer but used cheaper, basic circuit parts. This could be the “alternative” way to put an accelerometer function in your projects without spending much money but with a LM555 timer chip.
The idea behind this was to design a capacitor using a petri-dish and aluminum foil covering half the petri-dish and using water as the dielectric. Beca
