Magnetic spooks??(12 posts)

Magnetic spooks??Peter E

are there anyway to make spooks permanent magnetic? That could be a way to get rid of the magnet used to the cycle-computer. When it also seems to be such a problem to attach a magnet to the aero-spooks this cuold work well. any ideas??

(at least those observed at halloween) didn't seem to have any magnetic orientation whatsoever.
If you are, perhaps, referring to SPOKES, keep in mind that they are usually made of STAINLESS steel, which is generally non-magnetic.

I'm not sure, but I don't think that you can permanently magnetize stainless steel... a preferred spoke material... nor titanium or aluminium... let alone wheels with composite spokes...

Also, magnetizing a spoke would probably limit your sensor placement options a bit... there'd only be spot on said spoke where it would be close enough to induce through the sensor yet not hit the fork...

And, it's not too difficult to find magnets to fit a wide variety of spoke designs as well as specialty units (ala Ksyrium, SPOX and XAERO).

It's an idea... but in general, attaching a magnet (and the associated weight (since your magnet should be opposite your valve stem)) to spokes is not that big a deal (there are a lot of specialty adhesives out there for special applications... you just have to look beyond traditional cycling sources)...

We abide.

Quite so, also magnets have poles, one at each end. Thus the magnetic field of the north end of the spoke would be inside the tyre. And I have never come across a S/S magnet.

How about a hollow spoke with a wire running to an embedded micropulser, powered by a miniture hub dynamo?

How about a laser bar code reader. Tire manufacturers could bar code the casing with size info. The computer would self calibrate to the tire size.

The laser could be powered by a big magnet attached to the spokes.

I was thinking of generators in the brake hoods.

How about a solar panel incorporated into the helmet?

Why not run the power for the magnetic pulse generating magnetic pulse driven pulse magnet bar-code reader with a small wheel running on the ground, almost like a dynamo. It could be mounted next to the rearwheel, thus eliminating the need to unclip at lights. In fact, if it was the same diameter as the front wheel, the sensor could be mounted there, thus eliminating the whole spoke/magnet problem. Then, if it were steerable, we could dispense with the whole front wheel altogether, thus saving weight, and, as it's the front of the bike that causes the major part of turbulance/drag, this would make the bike much faster too. However, we could then gear up the size of the DYNO-WHEEL (tm) to compensate, thus giving a "true" normal bike reading.

When the redneck comes by to brush your arm, your magnetic spokes will pull you into him. You could end up stuck to the side of the vehicle!

And don't ride next to a steel bike. On the other hand, drafting behind a steel bike was never easier.

centers around the use of the word "spooks."
