I have managed to connect up the output of the LED controller to my oscilloscope. This is the non-Bluetooth version of the controller because it is still fully shrouded so it is much safer, but it should be the same as the same LEDs are plugged in. I was expecting to see a 50 Hz sine wave of some description, but instead, I discovered a 66V peak to peak square wave at 25 Hz, see photograph below. Apologies for the fuzziness of the photograph, I have not yet worked out how to transfer my oscillos ...
Whilst wandering around a local store after Christmas looking for reduced cost Christmas decorations and hence bargains - of which there were only a very small number this year, I noticed a Christmas Wonderland Bluetooth Transfer, for controlling a string of LEDs.

There was almost a complete lack of informati ...
Having become a little behind on the four week Open2Study Mobile Robot MOOC that I signed up near the beginning of November 2018 I decided to put some extra effort in and get ti finished.     I didn't quite manage to get 100% in every assessment as I couldn't bring myself to put the designer's test sequencing before safety, so even though I took the test three times I just kept getting one question wrong. Still, passed well enough to obtain my free downloadable certificate at some t ...

I thought of doing some post-graduate study which seemed to be at about the right level for what I wanted, but I didn't fancy a complete Masters or similar. I also wanted to be ab ...
