Intro: DIY Cheap IR Reflector for a Remote Control
This is a really easy hack for a remote control that can boost its signal power by creating a reflector behind the IR Emmiter. And it Definitely works. Now I can actually Use the controller. I got the idea for this when I was thinking about a way to increase its power. I was about to go down to Radio Shack to buy a second IR Transmitter, but then I realized that it would be much simpler to just put a mirror like device to focus the beam, instead of adding the extra emmiter to strengthen it.
Step 1: Materials Needed
1. The Victim Remote
2. Aluminum or Tin Foil
4. Opening Tool
The Opening tool can vary for different remotes. My old Sony remote only need a chisel to pry it open, because it had no screws and such.
Step 2: Take Out the Batteries
Take out the batteries. I forgot to do this step in the beginning. You have Got to do this step. lol. It's kinda important.
Step 3: Opening the Remote
As stated previously, opening the remote can vary. In my case, it just took a little coaxing with a chisel to open.
Step 4: Observe the Installation Site
Now we look for a good way to attach the reflector behind the IR Emmiter. In this case, we can just attach it to the plastic on the top half of the remote.
Step 5: Insulate the IR Emmiter
Since we're going to use aluminum foil, we need to cover the IR Emmiter's wires so that it does not accidentally affect the circuit, rendering the remote useless. An ironic conclusion if that be the case.
Step 6: Making the Reflector
The reflector is is made of a folded aluminum foil peice. Folding and size of the tin foil will also depend on the remote size.
Step 7: Mounting the Reflector
Taping the reflector to the remote does the trick.
Step 8: Re-Sealing the Remote
Now we put the remote back. Make sure all the parts are in their proper places, and squeeze! Be wary of the aluminum foil though.
Step 9: All Done!
Now you can use your new found Power-Mote. Do some quick tests with it to see if its working, and you're done!
