   Do you have any old hard drives laying around?
A particularly good one is a Seagate 9 gig SCSI drive. The magnets I got out of those will break your thumbnail if it is between them when they come together. (spoken from experience, Ouch!)

PS REALLY old hard drives just have stepper motors, and the full height SCSI's are not neos.

I don't think rusty has said but the tri-gate magnets & spheres he appears to be using are from a common toy magnetic erector set you can buy in any toy shop - can't remember the name right now - fine for POP I would say.

@ Chap

I have a gamut from 2X height full width 2G fast, to 9 & 18G SCA-ultra-wide-ultraSCSI.

But what is the form factor?
If it's like the mu-metal backed crescent shape with a pole on either end, I'm not sure it'll serve for repel or attract.

Hmmmmmmmmm....that has me thinking of tri-gates.
Hmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmm...............



Guess i have 2 experiments to do tomorrow.

Hi Rusty/Graham,

I was wondering if you had tried differing sizes/strengths for the tri-gate/roller assem.

Like 6 -  3cmx.5cm for the gate and 2cm x .25cm roller, or vice versa?

Bigger trigate/smaller roller = more velocity?
Bigger roller/smaller trigate = less velocity?


Just curious as I'd (for expenditures sake) like to use the smallest gates/biggest roller combo I can get away with for the combo wheel.

Trigate lift tests are still not done, but should be tomorrow when I get my car back from the shop for a brake job.

THAT was fun trying to explain what that extra stuff under the hood was for, but he's interested and would like to offer it (HHO enhancement) to customers if I can prove I get even just 10% better mileage with a 50/50 profit split.

Take care Rusty/Graham

Hi Exx
I did try smaller magnets with same size roller and same size steelball, I was getting the same results from that, I also try bigger Trigates with the same size roller, if I can remember the force was less or not as strong because the distance the roller was from the back of the gate.
The back of the gate is where most of the flux reacts thats why I have the shields at the back.
One thing off subject I find it better to shield magnets by deflecting the field so if I want to take the repel away comming in I would place a magnet behind the main magnet so the flux from that magnet is attracted to the magnet behind and not trying to reach out to the magnet comming towards it.

Hi Fletcher
There Geomags mate and yes I have said.

PS Geomags and other toy mag sets are good for experiments but the Trigate will work with any cylinder magnets, the Geomags have a steelbar connecting two magnets at each end others have an air gap instead of a steel bar so there not as strong, I had some of those cheaper ones so I cut them to get the two small magnets out and used the small magnets for my smaller Trigate test.
