Solar Power Monitor
Not technically a clock, this was commissioned by a company called Primrose Solar to display how many MW/h of electricity are produced from their Solar farms in the UK. Looks 1930's on the outside and inside is bang up to date with WiFi and embedded tech.
It has 9 of the very large IN-18 tubes, lit with RGB led lighting and they are controlled by a Raspberry Pi. What looks like a dial pointer, is actually a second hand from a regular wall clock! It is driven via a servo motor controlled by the Raspberry Pi, and can be programmed to indicate voltage / current etc.
I am not limited to just making timepieces - I'll have a go at anything! This was an interesting project for me to work on, and still involves a lot of the processes and steps required to make a clock.
