Introduction: Easy, Low Cost LED Bracelet!!!!!!!
For this Instructable I will be showing how to make an awsome and easy L.E.D. bracelet made with stuff you probebly have in your house!!!
Step 1: Tools and Supplies
You will be needing the following tools:
X-acto knife (a box knife will do just fine)
Needle nosed pliers
And you will be needing these supplies:
6-10 L.E.D.'s depending on the size of wrist (the color of your choice)
Ample amount of 1/4'' I.D. (inside diameter) vinly tubing
One button or switch
One AAAA battery (yes i said AAAA for a reason)
Step 2: Aquiring the AAAA Batteries
Now you could go out and spend around $5 alone just for the AAAA battery or you could get them from a regular 9v battery
The first step would be to start opening the case of the 9v battery.
After you get it open you will find 6 AAAA batteries. Thats what we will be using to power our bracelet
Sorry for the blurry pics
Step 3: Making the Strand of LEDS's
Now to start making the bracelet.
First you're going to want to cut just enough tubing to go around the largest part of your hand
Now set that to the side and lets start working on the LED's
we are going to run them inline like they are in the diagram checking to make sure they are conected properly by testing the strand every time you add a light
You're gonna want to make a strand the is about an inch and a half (1 1/2") shorter than the tubing
(I ended up using around 8 in my strand)
After the strand is done solder 1 long wire onto each lead of the LED (at least as long as your tubing) then put a piece of tabe between the 2 leads to keep from shorting
Step 4: Finishing the Bracelet
so now you need to feed the wires on the strand of LED's through the tube and pull the LED's through with the wires where there is about 3/4" of empty space in the tube
Now cut the negative side of wire with about 2 inches of it sticking out
solder that end to the switch
then solder a 1" piece to the other terminal of the switch
once your done with that
i took a piece of the metal contacts that were holding the batteries together in the 9v and bent it to make a L shape with a bend on the back to hold it in place inside the tube
now do the same thing on the other side with the positive terminal and NO button
slide the positive end of the battery in the positive side and the negative in the negative
mount the switch and tape the battery in so it doesnt came apart
We have a be nice policy.
Please be positive and constructive.
