The From Shadows team requested a large countdown timer to count 2 hours, I offered a full 99 minutes instead to save myself an extra digit but I think this giant RGB seven segment display fulfils the brief well. I opted not to use a real time clock chip because it only drifted a few seconds over the two hour period which is close enough. The illumination is provided with WS2812 LED strips and the controller is the ESP8266 so if I desperately wanted accurate timing I could always implement an NTP server and connect to the local wifi. Again, I wish I'd taken more photos of this project in action but I may well get another chance if I build another one for our local ninja warrior training gym .
