Secret Scotland

If it's secret, and in Scotland…

When Christmas lights go rogue

After the recent silly story the media decided to make some mileage out of, I couldn’t really leave this little gem out.

Especially after noting I had withdrawn from this game after the cheap Chinese microcontroller based stuff started to make my hand-crafted offerings look sad and ‘simple’.

While I know a lot of cheapest and nastiest stuff which can’t pass UK/EU safety rules, having looked at quite a lot of the design of the LED controllers and some pretty ingenious wiring/control systems they use, there’s a lot of clever ideas in those systems.

Some of them can take a lot of thought to ‘reverse engineer’ to see just how they work.

I’m not sure what impresses me more – what can be done with microcontrollers that have as few as 16 pins (or even 8, or less), or how anyone manages to plough the manual for such things, which can run to dozens, or even hundreds of pages to describe all the goodies hidden inside, and to access/control them.

I saw one reviewer comment on one that was selling for the equivalent of 3 p!
