LED 5-Minute Dot Clock
Made with either stained or painted wood and 3D printed dots, this clock is accurate to 5 minutes, as it updated every 5 minutes. There's no need to keep checking the time every minute, 5 minutes is good enough. Plus, most things are scheduled to 5 minutes anyway.
This code for this clock has been developed completely in house using a Raspberry Pi Pico and Arduino. It runs on 5v, so you can plug in the usb cable to any 5v wall brick or outlet and it should work fine. it can also run on battery power for a short time depending on the capacity. In testing, it survived about 24 hours on 3 AA batteries. Currently, there are three standard colors, but custom configurations can be made as always through requests.
