Looking for a radio actuated switch thing... - RC-Monster Forums

lincpimp · **Looking for a radio actuated switch thing... -** 12.18.2008, 05:14 PM

Here is what I am looking for. Something that I can plug directly into the receiver and use it to switch my led lighting on and off via the 3rd channel. It would be nice if it has a pos and neg output, with either switched, but preferably the pos wire.

Anything like this exist? Does not have to be able to hand a ton of power, I am only using 6 leds total.

That'll be $10 please....

That's nice. Too bad it uses a mechanical relay rather than a solid-state solution...

Something like this: http://www3.towerhobbies.com/cgi-bin...?&I=LXCJD6&P=0

Kinda large, but maybe could be taken apart and repackaged...

Must you crap on everything I do?...

A bit big, but I do like the solid state electrics...

Nice, but I think we have a winner below...

Not quite, but you put me in the correct place, check this out: http://www.robotmarketplace.com/products/0-DGSW5.html

Perfect to do what I need, plus I can use it for 2 different light setups, like general running lights, and a set of top lights for the roll bar. I can setup the 3rd channel of my m11 to do a 3 position setup, or just use the knob on the m8 to do it. So i can run the running lights by themselves or all at once. Quite gangster... Much better than what I came up with:

It's what I do! I did say it was nice, didn't I? It sure is a heck of a lot smaller than the one I posted. For low current loads like LEDs, I'm sure a relay will be fine. There. Happy now!

Thats more like it....

I wonder if you could add extra LEDs in parallel- given the low currents, I think its do-able...

BrianG · 12.18.2008, 06:56 PM

lol, that's pretty funny! But it got the job done right?

Yeah, I will do... I really like the dual switch I linked to. I just need to find 5 white leds that have the correct resistors for use with 5v... Any ideas where to get those pre-assembled? I would rather not have to solder all of that up, and I have no idea what resistors to use...

White LEDs drop around 3.5v each, and you typically run LEDs at 20-25mA of current. So, (6v-3.5v)/0.02 = 125ohms. Resistors from 120ohm (21mA) to 150 ohms (17mA) will be perfect. Each one will need one of these resistors.

Space is a big issue with this project. I have to fit the led control box, ubec, and whatever switch I use in a small tupperware that I have here, 1.75"x1.75"x1"... Had to custom make it to fit under the hood of the high lift...

I will order the Dual 2.5a RC Switch from robot marketplace and let you guys know how it does...

Man you are useful Brian, if only you lived closer I could bribe you and have you make all of this stuff... Would the resistor go on the neg wire? And how do you tell polarity of the led, is one of the "legs" longer than the other?

1) Doesn't matter.

Hahaha, brilliant. I had thought about a microswitch and servo combo, but thats a nifty unit you built there; zipties- man's new best friend
