I know the board says not to repost if your post doesn't show up immediately, but I waited about an hour and my response never showed up, so apologies if this does double post.
I'm creating this for a hobby/game called geocaching. This is where seekers with GPS devices solve puzzle and seek out "treasures", which is usually a small box with trinkets in it. In this particular case I'm designing my own puzzle. In it seekers will be told to seek it at night, and bring along a common TV remote (I'm considering providing the remote, since some are RF work differently). When they get to that location they have to aim the remote randomly until it lights up an LED (preferably a very bright visible one) So what I need to design is a device that has 1 or multiple IR receivers (multiple for increased sensitivity, and incase it's hit from an odd angle), that when they get a signal from a remote, will light up 1 or multiple LEDs. I know I will need receiver(s) and LED(s) and some sort of power supply, but not sure what other components I'll need or how to integrate this all together. I'm pretty sure I can work out a weatherproof housing to contain it all in, but I need some sort of design blueprint or schematic on how to put together such a device. Thanks again!
