Introduction: Trousers That Charge Your Phone
So we take close to 1000 steps per day without counting my physical activities that i usually have and if you are a regular cyclists like me that too counts. So what if we could somehow harness that electricity to charge stuff. SO this is an instructable where i tried to do something of this sort. This all started when a few of us were thinking out about an Eco friendly project a teacher had asked us to make we were yelling out all sort of weird ideas and somebody yelled out "pants that could charge your phone when you run". So that was the idea we stuck to and everything fell together and we made this.
Step 1: Basics
So the basic idea of this is that using electricity to charge something rechargeable. The main problem is from where to get the electricity. So what i thought about was attach a motor in each knee joint area of the trousers and a motor in each thigh joint of the trousers. So you might be knowing if you spin the motor's axle manually you get electricity from the wires attached to the motors. so that electricity get stored in a battery and from the battery you can charge your electronic device by plugging it in.
Step 2: Parts
for this project you will be needing :
- 4 dc motors (i got mine from old toys)
-1 rechargeable battery with its USB charger cable
-1 USB adapter (i used one from an old wall adapter)
-electronic device that you need to charge with its USB cable
-and obviously a pair of trousers (i used some old trainers)
i didn't have to buy anything, but if you have to buy them all together (apart from the electronic device) it would cost you under 2 bucks.
Step 3: The Hinge for Spinning the Motor
i used a cardboard disk and attached another rectangular piece to it and attached it to the motor with a screw but you would want to attach the hinge after attaching the motor to the trousers. The rectangular piece of cardboard that goes for the knee joint should be slightly smaller than the size of your shin an dthe one that goes for your thigh should be slightly smaller than your thigh.
Step 4: Attaching the Motor to Your Trousers
First what you could do is check in exactly which areas your legs are bending mark those areas and make sure the disks attached to the motor are right on top of those areas. I attached motors to my knee joints and to my thigh joints.
and i stitched my motors on but you could try some other ideas and i stitch that rectangular piece of cardboard somewhere in the middle of my shin.
Step 5: Circuit
the circuit is very simple the four motors will be attached to each other in parallel and the two ends will be connected to the USB charger of the battery. when the battery is fully charged you will have to unplug it and attach it to an USB adapter which will connect into your electronic device.
Step 6: After Charging Battery
after charging the battery you have to unplug it from your charging cord and attach it to your USB adapter. attach your electronic device and boom it should start charging. SO say bye bye to wall adapters and plug points this is the future but think about the further future you wouldn't have to look like a complete cyborg nor would you have to carry battery and adapters in your pockets and maybe you could attach these things into your jaw the exact same thing and you could charge your phone while talking this is the future everybody think big get ideas and make stuff even though they might not work.
And please send me better ideas in the comments and if you find a more efficient way to make this work please do and share the ideas with me.
Thank you everybody
