RF SPST switch

you are not trying to build an IED, are you?

i

Arg! I had to look that acronym up in google. :-)

No, i'm not. I want a switch to power up a small LED light when I approach the tent or my car in the dark. :-)

Maybe activate some circuitry when i come home, have to think more about that part. That's why one of the requirements was two to three walls of range.

Although, I admit, the application of this kind of switch could be very broad. :-/

Oh, yes, and I asked for an on/off switch. Not just on. :-)

You know how to build one?

Viktor

If you have anything like Radio Shack in your country, you could just buy a transmitter/receiver pair. I got a set once for about US$15.00, with a transmitter like a key fob, and the receiver used the exact same injection-molded plastic case as a coffee timer, but without the big knob on the front. ;-)

Good Luck! Rich

There is something like Radio Shack...

I know that it's possible to buy remote for mains power switch, dunno if there is a battery operated one.

But I'd rather buy the components myself and build it myself. And would probably pay less that way. :-/

:-)

Hello Viktor,

Years ago I have seen a camping lantern that came with an RF remote (!). Blew my mind, couldn't believe it, couldn't imagine why on earth they designed that. It was bought at a regular camping store.

You wouldn't pay less, and, given the way you described your skill level, it is likely wouldn't be able to build it yourself anyway. Get the Radio Shack or equivalent device. Or modify a cheap R/C setup to light the LED. Radio Shack sells something called a Zip-Zap - a small R/C car - that might be a good candidate. Maybe your Radio Shack equivalent sells something similar.

Oh, c'mon, give me a break.

I managed to build this:

and this:

and some other stuff that's not on the web.

Leave it to me to decide what I can and what I cannot, thank you.

Now, if you have something that could help me, I would be grateful.

Viktor

Why do people have motion sensors activated lights in their back and front yards?

My guess is so they could see their path and door when they approach, maybe where to stuck the key etc. What do you think?

Viktor

Security. They come on when someone enters an area they are not supposed to. The fact that they light your way is just an extra benefit.

Hello Viktor,

Not really. They think it increases security, and to some extent maybe it does. But you'd have to discount all those nights where everybody woke up "hooo, there's got to be a bad guy out there..." after the sensor was tripped by a bat or a cat.

Seems everything is remote controlled these days. Some day even our foxes will probably demand cable TV and a remote...

Hello Viktor,

One more idea just came to mind: Remote doorbells. We have one and the receiver in the bell operates from four D cells. They are in there since more than five years and still fine. These bells are cheap, about $20 in hardware stores (US). I don't know what it would be in your country (Hungary?). Maybe you can find a schematic on the web if you really want to build your own but unless you have most parts already there it's probably going to cost you more.

The transmitters for these bells can be either of two things: A little box hooked up to the primary bell and thus low voltage AC powered (that's what we have) or a small transmitter with a coin cell (that's what you'd probably want).

I was at the bank today, and in the next line was a guy with a mini-telephone attached to his ear.

All I can think of when I see those people apparently talking to themselves, is a strip in MAD Magazine, back in the '60's, when "transistor radios" were becoming so popular that kids of all ages were holding them up to their ear while walking down the street, so they could listen to their favorite station. In the strip, the author predicted that eventually, the human ear would evolve to hold the radio in place, so they could listen to the radio with hands-free!

Odd, how prophetic satire can be sometimes. ;-)

Cheers! Rich

Check out the remote control at

It's pretty much exactly what you want, with a few options. Not a kit, but if I were looking for a simple remote control device, I'd definitely buy this.

Cheers!!!!

They call it PMS because Mad Cow Disease was already taken.

Ok, apologies if I misunderstood your description of your skill level.

Well, I already did, but you didn't like it. So I'll try again with something different:

You may be able to use the transmitter & receiver they offer, without the encoder and decoder. You decide.

Ed

Well, that is an option. I'll have to check out what they have.

Viktor

Mmm! Now this is nice! Thanks! :)

But the size is a bit more than I would like. Well, I'll have to figure something out.

Thanks again,

Viktor

Croatia.

Thanks for suggestions.
