samchurchill Posted April 29, 2018 Share Posted April 29, 2018 Hi all, I'm looking for a wireless way of triggering a battery-powered LED sign (just some LEDs in the shape of a word) and wondered if any of you can recommend anything for this. Ideally it would just be a simple hand-held device like a garage remote. The range only needs to be about 10m, but through around 10 rows of people standing up. In case you're interested, it's for reminding occasional speakers of mic technique once they're on stage, even after they've been reminded by the stage crew! Thanks, Sam Link to comment Share on other sites More sharing options...
timsabre Posted April 29, 2018 Share Posted April 29, 2018 Look on ebay, there's loads of radio controlled relay boards.For examplehttps://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.co.uk%2Fulk%2Fitm%2F282560031588 Link to comment Share on other sites More sharing options...

beware Posted April 30, 2018 Share Posted April 30, 2018 Similar to a traffic light system. Run it down XLR with a switch at control. Link to comment Share on other sites More sharing options...
samchurchill Posted April 30, 2018 Author Share Posted April 30, 2018 Thanks everyone. I think I'm going to try something like @timsabre suggested - just couldn't find them as I didn't know what to search for! Thanks again Link to comment Share on other sites More sharing options...

adam2 Posted May 10, 2018 Share Posted May 10, 2018 Yes, look on fleabay for "12 volt wireless switch" mains voltage units are also available, but I consider 12 volts to be safer for this sort of thing. Although primarily "line of sight" they will work with modest obstructions in the way. Get one with a very generous claimed range, remembering that this is probably in Chinese meters. I have one, used to switch on additional external lights from indoors, I don't think that the exact unit that I have is still available, but fleabay is full of broadly similar units.
