A binary clock using an ESP8266 board with some 74HC595 shift registers to drive LEDs. Uses NTP to get time over the network. Also has modes to show it's IP and ping-pong a led back and forth.
Built with an ESP32-C3 Mini, which I bought for 1.83 here
To run tests you need to have configured the platformIO native environment. See the platformIO guides for more detail.
After installation, run tests by navigating to native > advanced > test in the
platformIO sidebar.
The PCB and schematic do not include the LEDs. An 8-pin connector is offered, as well as a mounting hole for the LED ground. The intention is to use a piece of 2mm solid core copper to attach the LED ground to, with wires leading to an 8 pin connector which will plug into the PCB. The entire board can be powered via the ESP32's USB-C connector.
