I've been wanting to make a cloud lamp for ages at Three Ways and there are a tonne of tutorials online if you want to follow one of them. I wanted to have a remote control for mine but didn't really want to bother with decoding IR or RF signals whilst trying to do lighting animations. I have used those key fob remote controlled relay modules before, but its massive overkill to control an Arduino pin. I spent a long time looking for a remote module that could control 5V pin logic and sure enough found one that is made by Adafruit, but unfortunately it is on 315MHz which is illegal to use in the UK. Seeing as it is the military channel I didn't want to mess with that really and couldn't find any UK options until I found this amazingly retro thing!
I found it on the 'Flux Workshop' eBay shop for £5.29 which is great for the time and extra hardware it saved me. I have not tested it extensively yet, but it seems to do what I want it to, is on 433MHz which is UK friendly and is the only option besides rolling my own apparently.
Anyway, we now have a way of selecting between 4 presets remotely so I can hang the cloud out of reach, which is good because it would be shredded in seconds!
I'm not sure what I am gong to do about dusting yet...
