Introduction: LED Patchie
An LED Patchie is like an LED Throwie, but you can write your message with this object.
It is a acrylic glass, witch is illuminated by an LED. You can engrave something and tape it everywhere you want.
I don't know, if somebody has had allready the same idear. I like this projekt and it should take not more than fife minutes to finish it up.
It is inspired by the cool work of the Graffiti Research LabGraffiti Research Lab.
Step 1: Cut the Acrylic Glass
Nothing spezial. Just take a cutter knife and cut a piece of 10 x 4 cm out of the plate. I took a 2mm thick acrylic glass and cutted it four times on both sides. Than you can break it quiet easy.
Step 2: Drilling the Holes
Now take a 22mm driller and drill the hole for the battery. It schould be a 3V Battery (2032). Place it on one side of the plate. Next to this hole, drill the hole (10mm) for the led.
It should even be possible to place two LEDs in the plate, if the light is not enough for you.
Step 3: Placing the Components
Take the LED (I took a ultrabright green one.) and put it into the 10mm hole, the legs facing to the battery hole. If you're done, put the battery in the 22mm hole. The long leg of the led schould be on the + Side of the battery. Now tape some electrical tape to fix the legs of the led on the battery and to cover the led, that it want blind you.
Step 4: Engrave Your Message
Now it's time to finish the project. Take what ever you want to engrave something into the plate. I tooked a Dremel, but a cutter knife, a soldering iron or something to etch, will work as well.
Now your done. Take the LED Patchie with your message and place it somewhere. You can tape it or build magnets into it. Hope you have fun with it.
Update: Pixelrider says in the comments:
The fun part is that you don't have to engrave your message - simply write it with a marker pen - especially those UV-sensitive - and use blue/UV LED ;)
I think, that is a gread idea because, it makes it more easy.
