This item is an LED clock display designed to interface with (and power) the Raspberry Pi Zero or Zero W. It has a MAX6951 wired up to the SPI GPIO pins (for /dev/spidev0.0) and software is available for the Pi to display the current time with a granularity of a tenth of a second. The board has a 2.5mm jack for a 5 volt 2.5W power input, which powers both the pi and display. The pi can obtain accurate time from the Internet with NTP using whatever networking options you may wish (most convenient is the new Pi Zero W with built-in WiFi).
My GPS Clock is the inspiration for this item, but sometimes getting good Internet connectivity is easier than getting good GPS reception.
The clock optionally comes with a Raspberry Pi Zero W and/or an SD card. Other networking hardware is not included. The clock board comes with a female 40 pin GPIO header. If you add a Pi Zero W, then a corresponding male header will also be included. If you order your clock assembled, then this header will be soldered onto the Pi. If you order an SD card, it will be configured with PiBakery for your WiFi network (add a note to your order with the SSID and WPA passphrase) or Ethernet (Ethernet hardware not included). On its first boot, it will download and install the clock daemon, so Internet connectivity must be available.

I design and build small, useful electronic things. I started in 2013 after leasing an electric car and deciding that I could build my own charging station. Since then, I've gone on to design lots of things to fill particular needs.
The name of my store is partly a nod to Arduino's Italian roots, since Arduino got me into microcontroller engineering, and that led to everything else. I also like the image of Geppetto, working away in his workshop making little things that come to life.
