I was fed up losing contests one by one. I made this project to participate in Duct Tape Challenge.
This is the duct tape flip flops which can light up in the dark to see the ground.
In this instructable I have improved my Photos as I have read somewhere to improve photos to win a contest.
Step 1: Gather Materials
1. Thermocol Sheet
2. Duct Tape
3. BC548 Transistor
6. Button Cell
8. 1k Resistor
9. A Flip Flop
Step 2: Something About Duct Tape
Duct tape or Duck tape is widely used all over the world to adhere. It has Low Density Polymer(LDP), and some other polymers.
Its Uses are:
1. It is used for insulation
2. Used to Adhere
3. Used to adhere at high temperature
4. Duct tape was used in MARK Project for protection from Grizzly.
5. It is also used By NASA For space Research Work.
Step 3: Creating Base
Take a slipper and cut the thermocol sheet of two layers as shown in figure.
Make a hole exactly by comparing original footwear of your size.
Step 4: Creating Joule Thief
Firstly Make a Toroid winding two wires around Ferrite bead.
Follow the circuit diagram and your Joule thief is ready.
It can work on the voltage less than 0.135v.
Step 5: Ready With Your Joule Thief!
Dont solder LED on PCB and attach it externally.
Note: Do use Switch as shown in figure as I did not mentioned it in Circuit Diagram!
Step 6: Assembling It on Footwears
Attach the circuit below the low pressure area of your Palm. So not more pressure is exerted to circuit and Toroid.
Assemble the components as shown in the image with a duct tape.
Step 7: Add the Second Layer of Sandwich
Add the second layer of thermocol and adhere it with Duct tape.
Also adhere switch in the position as shown in the image.
You can on.off the switch as per your need.
Add straps of footwear with the twisted Duct tape in the hole.
Step 8: Walk in Dark
Now you are done with your See in Dark Flip Flop.
