I've started doing gold plating again and was getting frustrated at having 3 different kitchen timers on the go, so I built a single unit to cover them all.
I'm already working on Version 2 which will have a bigger screen and will include the option to cut the power to a tank when the timer finishes. Oh, and a different notification tone!
Finally, if you're one of the people who watched my brush plating wand video, thank you! It sat for ages with very few views and then suddenly a few thousand - which is nothing in the grand scheme of things, but brilliant to me!
