In an attempt to gain some electronics knowledge, I bought $30 worth of components and breadboards from Amazon, and built a 2-transistor LED flasher.

Wireless Charging Detector

I dropped my cell phone and cracked the screen, so I got a Google Pixel 6 and a wireless charging stand. I ended up looking up the “Qi” standard for these chargers. It seemed like the coils used to transfer energy weren’t particularly exotic in size, shape, material or manufacture, so I decided to try to receive some energy from the charging stand.
