Rechargeable ESP8266 Deauther + Hackerbox #26 Skull kit.

The “Wan Grenade” is Stefan Kremser’s amazing ESP8266 Deauther firmware with some code added to communicate over UART To the skull badge I built from Hackerbox #26. The badge operates as a separate thread for led and buzzer output.
Not particularly useful, but a good learning experience and a nice proof of concept for using the ATTINY85 as a UART slave.
