Batteryless Dynamo on Bedini

The batteryless dynamo in this video was purchased from freelights.co.uk
And they are wicked...
They are so cool... I havent fitted them to my tricycle ;)

A bit misleading...

The Bike light device that was purchased is "batteryless"... however the bedini motor has a power source.

So it is simple induction.

[waterboost]

I agree...but... the interesting thing here is that it illustrates how much cheaper (efficiency wise) it is to modulate an existing magnetic field, rather than create a new one. It doesnt slow the bedini when positioned after the ferrite rods inside the bedini coils...

[MattBlytheTheOne]

so did you fit your bike with one?

[waterboost]

Yes, I did and it still works ;)

Shame I dont ride it much...

Just got mine yesterday, took it apart ( got to be careful there are VERY fine wires inside had to resolder mine ) But I have ordered some 1 inch neo spheres, Can't Wait till they get here :)

[waterboost]

Yeh.. the wires are like hairs... I did a panic and put it back together before I broke them :)

How big is the standard ball? Is it neo? What do you think? Cool?

[simulanics]

@waterboost ferrite would not work...soft iron or soldering rods work... a ferrite rod would absorb the magnetic field rather than generate one.....

[MrThair58]

we can not see any thing.

[grokker]

magnets, how do they work?

[lazyray304]

dont you have a table???

[Joeviocoe]

Right, there are no losses do to friction or inertia.
