For the next ESP Trick from ESP…
It's a pretty corny 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 magic - that he has 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 find out from the list of things you need. The matrix contains a gyroscope and uses a small ESP module to transmit its current orientation to a display. There is a small reed switch that allows you to turn off the device with a magnet. Without it, the battery will drain quickly.
The receiver is another larger ESP8266 and as a proof of concept it only outputs the matrix coordinates through a serial port. To really make this a winning magic trick, you should probably have it pass the highest dice face to your smartwatch or something clever like that. So there is still a bit of work to do.
Frivole? Sure. But still fun. Building something like this into a better looking dice with wireless charging could probably make a product you could sell in magic shops. As it stands, though, it would be an interesting project to do with a kid or just for fun.
We thought about the LEDs on the face of the dice, but then realized that would really drain the battery. If you don't have enough dice, take a look at the electronic farkle.
