Chinese electronic lego timer module
Added 2025-04-25 05:28:30 +0000 UTCI thought this was going to be an easy video to make, but it wasn't.
It took a LONG time to work out all the modes this unit has, test them and then basically write the entire English manual for the module in the description of the video! I had to remove some of the description because I hit the character limit!
It's quite a handy module though, even if it does have some issues with its power supply circuitry. The odd choice of an LM317 voltage regulator for 5V means that it will dissipate a lot of heat if the relay is on for any length of time while being powered from more than 12V.

Both are showing for me. It might be a country specific thing.

Very wild, the amount of programming in that little chip. Thanks for sharing this Big Clive! I came to the thought of use in hydroponic watering being like ten minutes on and 50 minutes off - repeat There's really a lot you could do with this. Maybe a one second quack noise followed by x number of minutes off to annoy room-mates. LOL
