For the ESP’s Next ESP Trick…
It is a pretty stale dad joke to tell someone you have ESP when you mean you have an ESP8266 or ESP32 in your hand. However, [Naufil Metkar] uses an ESP device to pretend — via a magic trick — that he does have ESP. The trick requires a bit of 3D printing, an MPU6050 gyro sensor, and a lot of showmanship.
We hate to spoil an illusion, but you can probably figure it out from the list of things you need. The die has a gyro in it and uses a small ESP module to transmit its current orientation out to a display. There is a small reed switch that lets you turn off the device with a magnet. Without it, the battery dies quickly.
The receiver is another, larger ESP8266 and as a proof of concept, it only outputs the coordinates from the die via a serial port. To really make this a winner magic trick, you should probably have it beam the top-most die face to your smartwatch or something clever like that. So there is a bit more work to do.
Frivolous? Sure. But still fun. Building something like this into a better-looking die with wireless charging could probably make a product you could sell in the magic stores. As it is, though, it would be a neat project to do with a kid or just for the fun of it.
