6:32 Initial idea of the device

Paperclick is an IOT device for tracking activities in a very easy way. By tapping on the display it will update the current date & time which the device gets from an NTP server. So you'll ever know when you did a task the last time. Additionally it could do other WiFi based tasks like updating an online sheet with the timestamps the device was tapped.
Paperclick is based on the ESP32-C3 RISC-V processor. Additionally the board is equipped with a LiPo charger, a WS2812 LED and two user buttons on the sides. The battery monitoring as well as the latching circuit is optimized compared to my other IOT devices, which results in a current consumption of just 140nA in idle state.
