Introduction: Survival Power and Fire Aid Kit
Let me show you how to build a kit like this .
Step 1: What Do We Need ?
1:old power bank.
2:led head light.
3:heating wire 0.17mm thick and 50mm long that comes to 3.5 Ohm .
4:3d printed fire can .
5:Slide switch .
Step 2: Testing If We Can Make Anything Purn !!
And as you can see it worked at the end , you have to make sure that your power bank can provide
enough power to make the wire heats up.
Step 3: Almost Done
After 3d printing the box and the cover , extend the power bank level indicator PCB wires , glue the slide switch , soldering the VCC and Ground wires from the USB output pins connect the ground to LED ground and the VCC to the switch mddle pin to the LED via a variable resistor for current limiting it is time for testing :)
Step 4: Does It Work ?
Yes it does :)
Step 5: Final Look
We have a be nice policy.
Please be positive and constructive.
