How to make a remote control on / off switch

AI Thread Summary
To create a remote control on/off switch for a string of low-voltage LEDs, users suggest repurposing existing devices like a cheap remote-controlled car or a remote dimmer switch. Hacking an R/C car is highlighted as a simple and effective solution, avoiding the complexities of building a circuit from scratch. Participants emphasize the importance of being cautious in public spaces to prevent unintended activations. The discussion reveals a preference for practical, accessible methods over more complicated DIY approaches. Overall, repurposing existing technology is seen as a viable route for achieving the desired remote control functionality.

Hi all,

I would like to make a simple remote control on / off switch. It is for a string of LV leds. 12 V and 0.24 amp running from a battery supply.

I would simply like remote switch instead of a toggle so no one else can fiddle with it.

Can anyone help me, I have been scouring the internet but can find little advice...

Thanks,

John

Once I needed a remote controlled circuit, and I bought a $2.99 R/C car and hacked it. It was way easier than making one from scratch. Just avoid parks and place with kids or be prepared for many undesired triggerings.
 
Hi Sakha,
This is a very good idea. I had been thinking about pulling apart a remote dimmer switch for interior lighting. Your way sounds more fun.

Thread 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...

Thread 'EMF (Electromagnetic Field) & EHS (Electromagnetic Hyper Sensitivity)'

Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
