Helping Hands for Cheap. Spinning Light Toy. As a young child, I was mesmerized by the spinning light toys in Disney world. I wondered how they worked and I was never allowed to buy one. Now, years later I decided I would make my own LED spinning toy that does the same thing as the ones in Disney world, but it costs much less and it has much brighter lights. Here is a link to the spinning light toys sold in Disney world: The idea to make this came when I saw my little brothers friend bring home a light spinning toy from Disney world. My little brother was pretty jealous and was dissapointed when his friend didn't let him try it. I knew I had to try to build him one, and I began brainstorming and drawing diagrams to figure out how it would work.
I was inspired to make this because... - I had many LEDs from solar garden lights and I wanted to use them. - I wanted to surprise my little brother with something nice. Electrostatic Turbine. Static electricity is high voltage (HV) at low current. That unexpected ZAP! Occurring when you walk across a carpet and touch a metal object demonstrates HV conduction by ionized air particles. Ion wind turbines use electrostatic forces acting between these particles to produce mechanical movement. I decided to go green by making this desk-top project from mostly dollar-store hardware; re-purposed plastic, cardboard and aluminum disposables from my kitchen recycling bin as well as some curbside junk from the neighbors next door.
The turbine uses foil electrodes that encircle a plastic, tubular rotor. Each electrode has a sharp edge that sprays a stream of positive or negative ions on the rotor's surface. Many sources of static electricity --from old CRT screens that "crackle and pop" when powered up, to room air ionizers -- will spin a reasonably well constructed turbine. Paper Claw 2.0. I was featured on HackaDay! Link: I was featured on Make Blog! Link: I made a paper claw a few months ago on instructables, and that design wasn't very good, it was small, it had rubber bands on it so the outside didn't look too great and it couldn't pick stuff up. I knew that I could make it better, the way of how it moved and was put together was not created until then, and I so far haven't seen any claws that use a design like this.
This claw is based loosely off that design by that it has the same way how it is held together, every thing else is different and better. This new design is bigger, it can now pick stuff up,and it uses a different way of making the claw open and close, so there is no external parts except the claw segments. The first 5 people to make it will win a patch! Here is the video: Well, anyways, to the instructable!
