Introduction: $1 Extension Cord
Why to buy, when you can make your own extension cord at your home at a price of less than a dollar.
Warning: Make sure you have good knowledge of electricity and how it works before making this product. I have used denim which is not a fire-resistant fabric because I wanted it for mobile phone charging purpose only. If you want to run high power consuming electrical equipment, such as- hair drier, Iron, washing machine, vacuum cleaner, pc etc, you should avoid denim because it might catch fire during spark or when the electric load is high.
- Plug with cable
- Four Plug-Socket
- Insulated Copper PVC Cable
- Rejected denim jeans
- Fevicol or any synthetic resin glue
PVC corrugated sheet
Trace plug-socket profile on cardboard. Maintain a gap of minimum 25 mm to create more room for plugs.
Cut a piece of denim which is large enough to wrap the whole assembly as shown here
Paste cardboard using Fevicol or using any synthetic resin glue behind the piece of denim and make cut-outs to insert plug-sockets and switches. After cut-outs are made secure all the plug sockets and switches using nut-bolts as shown in the video.
For wiring and making the circuit work follow the diagram. Make sure Negative and Positive terminals are not touching each other. Wherever wire covering is gone while striping, cover or mask it properly using electrical insulation tape to avoid any short circuit.
Only when wiring is done and circuit is working you can proceed to this step. Place a piece of cardboard above all the wiring and start closing it from all the sides as shown in the video. Let it dry for 5 hours. Stitch both the openings using nylon thread.
Cut PVC corrugated sheet as per length and width of overall extension cord and insert it in such a way that it should act as a barrier between denim and circuit. By doing so you will avoid any damages or fire catching to denim due to heat and spark generated by the circuit.
We have a be nice policy.
