How to replace the white LED from your keychain flashlight with a RGB LED.

Hi,
In this simple instructable I am going to teach you how to replace the white LED from your keychain flashlight with a RGB LED. A RGB LED is a red, green, blue LED combined into one LED. You can replace it with any color but I think RGB is the best of because it is always changing.

Step 1: Materials and Tools

Materials
10mm RGB self cycling LED-About 50 cents
The LED I have is a 10mm RGB self cycling LED. I bought these from Ebay (Top Bright)but you should be able to find else where. You have to make sure they are self cycling LEDs. This means the LEDs with cycle through all of the colors by them selves with out having to have an additional controller.
Keychain Light
The Key chain I am replacing is from Deal Extreme.com. Here is a link to the keychains. They are pretty cheap. Only $4.68 for 10.

If you want to buy the keychains and give me a referral credit that would be nice. Just click this link. Please don't consider this spam and don't feel obligated too click on it. Just trying to get some credit for my instructable. Thanks
Tools
Wire cutters or something capable of clipping the LEDs legs. I used my MAKE: Warranty Voider - Leatherman "Squirt" E4 (electronics version) Pocket multitool. (BTW this is the best Mulitool I have ever owned!!!)

Small Screw Driver-Any will work as long as it fits the screw.

Step 2: Disassemble the Light

The first thing you have to do is disassemble the keychain. It is pretty easy to do. Just remove the screws from the keychain on the back and pry it open.

im looking on ebay and im stuck on something.
what is the difference between cgi.ebay.com/20Pcs-5mm-RED-GREEN-BLUE-Slow-Flash-Rainbow-RGB-LED_W0QQitemZ250474721787QQcmdZViewItemQQptZLH_DefaultDomain_0

and http://cgi.ebay.com/10PCS-5mm-RGB-Ultra-Bright-ledCommon-Cathode_W0QQitemZ260570845284QQcmdZViewItemQQptZLH_DefaultDomain_0?hash=item3cab3b9064

do the second ones cycle through the colors too?

and im looking at 5mm bulbs because you said the 5mm ones work better, correct?

can dealextreme.com be trusted? 'cause the stuff is cheap on there.............
joejoerowley (author)  redon126 years ago
Sure. I have bought hundreds of dollars worth of stuff from them. It takes a while to ship but it is a good deal.
Good, 'cause my Radioshack days are OVER!!!
Good riddens ;)
remember, the stuff comes from Hong Kong, and shipping takes a while. if you only need 1 of something RS still might be best
Drop shipping seems to make it a bit quicker - if you don't know what i mean click on top sellers at the top of the website and "Drop Shipment and Gift Service (Removes DX logo from package)" should be the first one its one cent just add it to all of your orders and they should get through customs much quicker once they are actually sent (usually cuts a week or two off the shipping time for me :D)
Yes it certainly can, its a bloody awesome site dealextreme. The only problem is they can take a while to ship sometimes so don't be worried if your order takes a while to get to you.

I've bought a lot of stuff from them and only had one problem. I bought the more expensive led keychain and had to wait a couple a couple of weeks because they were back ordered.

So, the Done that you refer to in Step four is mine when I've completed the instructable? That's pretty cool.
joejoerowley (author)  mrmath6 years ago
Yes. It like a conclusion. Wraping things up.
That was my "nice" way of correcting your grammar. Your --> Belonging to you. As in this is your instructable. You're --> Short for you are, as in You're done.

Very nice. I have about 8 of those Photons in different colors and have always wanted an RGB one but those are expensive. Can't believe I never thought of this thanks!
joejoerowley (author)  Havok S146 years ago
Well I don't have photon brand ones. These ones are actually from deal extreme for about $5 dollars for 10. I actually have 5mm RGB LEDs now so it fits and works better which is nice. Thanks!

I hope you don't try to stalk me with one.....
joejoerowley (author)  Notbob6 years ago
No. I will stalk you with my 128 LED flashlight and green laser. Maybe I will bring a strobe light to make the effect even better. :)
I do like strobe lights.... How did you make this 128 LED flashlight flashlight?
joejoerowley (author)  Notbob6 years ago
I don't. I bought on deal extreme for $25. Here is a link!
Great job! This is super cool, I might buy a whole bunch of those RGB LED's and put them in stuff, those are super cool. Nice job!
joejoerowley (author)  GorillazMiko6 years ago
Yeah. I bought about 200 of them. I would recomend buying about 100 CR2032 Batteries too. The are a blast to play with.
