New youtube of magnet/coil "perpetual motion"

[Starcross42]

However, I would like to see details about the coil idea you had. If I understand the concept, it is good. Won't work in the fashion portrayed - for a few reasons but it may be a solution for other ideas.

I am still working my way around the site and have not been able to locate the original thread on the LEGO perpetual motion.  Sorry.
At any rate, there was a post on the first page from someone who linked to the exact coil, schematic, and a picture of the 'perpetual motion' pendulum toy that was the source of my coils.  That is exactly what I used, including the battery.  The coil was exactly the one pictured in my video.  Less than a day after posting my video one of your members revealed its secrets.  I was impressed.

The coil works pretty much the way I describe it.  The magnet swings into the coil.  A small amount of current opens the base of a transistor.  This shoots a jolt of electricity from the 9v battery into the coil creating a repelling magnetic field, pushing the magnet back out again.  The toy has a pendulum motion so the KE is turned into GPE, the pendulum stops, and the cycle begins on the other side.  I had seen a perpetual motion device at the Toronto Science Museum back in the '80s and I identified some black 'blocks' as part of a rotating wheel.  I suspect that they had a similar coil/battery system in these blocks that 'powered' the device, but they also had some nice distractors. 

As my initial motivation dealt with Back EMF I tried to come up with a way that it could be used as an unbalanced force in a system.  That was the evolution of my device.  I have not taken a coil apart so I can't give you a winding ratio, but the toys are easy to find.  There is a source from China called dealextreme.com that has a plethora of toys.  Actually, they have some very small versions that are driven by solar cells.  Light shines on it and it swings back and forth all day.

Hope that helps.

Hey YOU

Welcome in the cave of lions.

Still getting my feet wet.  No lions yet.  I'll keep my back to the wall.

When I ordered materials for a class set (500+) I was informed by the company that a security check is being run for orders over a certain amount.  That a limit was being placed on orders for ball bearings and that they were becoming more difficult to purchase.  As that was my only experience, I forwarded the information.  Thanks for your interest.

this story from the guy that banned me for not buying your story of the student who spun himself to death trying to go back in time to prevent 9/11  

You're selling a few ball bearings to people, not 500+ so even if your story is true, it doesn't make sense.  gee, wonder why there isn't a background check for buying boxes of nails, they're used in IED's too... Cartons of BBs... nope... just walk into walmart... 

So now that you've had the information for a while that they're not hard to find, I see you've changed your video to reflect the truth.  Oh, I guess not, why is that?  Integrity?

You can buy them from Ace and most hardware stores no questions asked.  Industrial supply stores are also an option. 

Or ebay, this is just from one seller: http://search.ebay.com/_W0QQsassZtoolsupply

Hello Padawan

Great video. What is the magnet configuration you have used there ? Is it something that's common knowledge ? I hope so.


Can anyone shed any light on that for me ?


thanks.

That was my post BTW. I figured that was the one you used and enjoyed watching most blow over it. That coil was by a fellow HAM.
