I'm interested in making the Deluminator from Harry Potter, but I'm new to all of this, so I'm not sure where to begin. The Deluminator is described as resembling a silver cigarette lighter. When you press the button on it, it turns off nearby lights and when you press it again, the light turns back on. I was wondering if there was a way I could do something similar with an LED light and a small remote control device.

I know it's a strange request, but if anyone could give me some suggestions on how to begin or direct me to any resources that might be helpful, I would really appreciate it. Thanks!

 

Just buy one of the cheap remote controllers they sell at Christmas for controlling wall outlets. They don't usually have an LED on them but I think it would be pretty easy to hack it so that the light comes on at the same time you press the button.

 

I'm definitely a Harry Potter fan and 50 years in electronics, but there ain't no such a thing in our world.
The remote control seems to be the only way. One person used a laser, but your aim has to be perfect and it won't look like magic if spectators can see the laser light.

So yeah, you're looking for a remote control as far as I can tell.
Accio deluminator!

 

This could be easily used I made it for a lamp and used my cellphone but it could be put in a small lighter like box and use buttons to turn off lamps remotely

Just use 2 esp one would be remote and one lamp controller

 

Bob Dobkin was at National in 1975 when he invented a Darkness Emitting Arsenide Diode but it never made it into production because of yield problems.

Recent progress is described in this news article is from 2015
Air Force reveals its new aircraft cloaking system uses dark-emitting diodes (DEDs)

And recently a demonstration appeared on YouTube.

They are currently in very limited production, are very expensive, and are only available to research institutions.

For years it has been believed that electric bulbs emitted light. However, recent information from Bell Labs has proven otherwise. Electric bulbs don't emit light, they suck dark.

This device is for 240V mains, but presumably 120V versions can be found.

Only trouble is that it will need a fairly large cigarette lighter to hide the remote control inside.
