Intro: Mini USB Laser Light Saber
This is how to make a small usb light saber. Since the new Star Wars came out I decided to make this.
Step 1: Get What You Need
What you need is-
A USB with wire ( I used an iPhone charger)
One laser diode
A button switch
Step 2: Cut the USB Wire
Their are two wires that you don't need because they don't transport electricity. I taped them to the side.
Step 3: Get the Laser Diode
This is a laser diode from a laser pointer and I put two wires on the positive and negative leads. I then taped it together.
Step 4: Attach the Button
I attached one wire of the switch to one wire on the laser.
Step 5: Now With the Two Wires You Are Left With Attach Them to a Long Wire
Attach the two wires to the two wires on the longer wire. U don't need to longer wire and u could just attach them straight to the usb.
Step 6: Then You Just Attach the Other Side of the Wire to the Two Wires on the Usb Like Shown in the Picture
Remember You don't need the extra wire if u don't have it.
Step 7: Tape the Two Wires So They Don't Touch and Cause a Short.
Step 8: Tape the Wires on the Other Side Like You Did With the Wires Near the USB Part.
Step 9: Now Tape All the Wires Onto the Diode So U Don't Have Wires Sticking Out Everywhere
Leave the switch out so u can tape that on the front.
Step 10: Now Tape the Switch on the Front
Step 11: Tape the Straw on the Front of the Laser Diode
Step 12: I Wrapped Electrical Tape Around It to Give It a Better Look
Step 13: The Final Product Should Look Like This.
Remember you don't need the extra wire I put in. It would be a bit smaller without it.
Step 14: Its Done
When u hold it and press the button down the light saber should turn on. It's red so I guess I'm on the dark side. Have fun :)
