remote controlled light - revisited Answered

Hello, Instructibles gang….

I originally posted a similar question over the weekend, and then got some feedback telling me that there wasn’t enough information to bring in worthwhile responses. My intention wasn’t to be secretive.  Rather, it’s a project that’s still in the planning stage and there aren’t yet many specifics. But I think I can still flesh it out a little bit, and hopefully gather some more specific suggestions.

I’m planning a sort of a scavenger hunt thing coming up in October. Most of the stops/stations will be fairly straightforward “orienteering”-type scenarios: “20 paces at 250 degrees,” “north to the hollow stump,” that sort of thing. But I still want to mix it up a little bit. One of the ideas that’s swimming around in my noodle is that, at one stop, folks will be told to “push the button.” It will be dark, so they’ll have to hunt for the “button”… basically a doorbell… and maybe secured to a tree (in such a way as not to harm the tree). When they press the button, a light will be illuminated at a short distance, leading them to their next stop. I know that I could easily do a simple circuit with actual wire, but it would be far nicer to achieve the same result wirelessly… and even though I’m not very electronics-savvy, I imagine it would also reduce the problem of resistance in the circuit. This only needs to operate over a relatively short distance… almost certainly less than 100 feet… probably much less. And while it must be able to operate out of doors (a woodland trail in a rural/suburban park) it only needs to last for a few hours. An LED… or maybe a chirping sound effect… something that would draw seekers from one spot to another.

Thanks for any suggestions. And please let me know if more information is needed.

off the shelf solutions: wireless battery powered doorbell. If you like, hack into the chime, and do somethin else with that voltage. Or wireless control for 110v light, fan, etc (available at walgreen, iirc)

holy cats,that's brilliant! I was planning a scouting trip to Lowe's but i hadn't even thought of wireless doorbells...even though we have them at work! Thanks!!!

heheh. sometimes it takes weeks to think of the laziest option. Sometimes it is the other fella that thinks of it.

If you were planning on a "wireless" approach, I'd suggest some sort of infrared detector circuit. They aren't terribly complicated or expensive (especially compared to radio transceiver tech).

It would only work well at night, of course--but that fits with your target indicator (light). The "transmitter" could be a simple as off-the-shelf IR flashlights (via ebay, etc) with a matching emission frequency.

Awesome! I'm sure I'll have some follow up questions on that. Thanks!!!
