Tablet Tracker - ESP32 Based

I designed a device for tracking when I last took my tablet as I have a dreadful memory. The device runs on an ESP32 C3 with a standard 0.96" 128x64 I2C OLED Display. The battery was harvested from a disposable vape but is a standard 13300 400mAh lithium cell. This is charged over USB C via a TP4056 module. I swapped out the R3 resistor on the 4056 for a 5.6k one to slow down charging thus prolonging cell life however you can exclude this step if you don't care about that. I also de-soldered the power LED on the C3 to improve battery life. The battery should be good for a few months as the ESP is put in deep sleep mode but I'm still testing this.

All in all the component cost is >£10 from sites like eBay ect.
