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 ESP32C3 RISCV 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.
