Video 75 15,000 rpm with Jonny Davro Bedini motor ( see correction video )

Place a strip of reflective tape on the rattlesnake egg magnet and I got some accurate measurements of what we already know, this baby moves!!! Note I have since found a flaw in the way this was measured it is really about 15,000 rpm.

That is great to have numbers on this. That was really turning. Nice work.

@Pirate,

I adore your earth battery, where did you get carbon rods? You really got me thinking now that you got the Jonny magnet running on an earth battery. I am thinking why not a small water pump...... Also why not use a standard battery ( dead one ) as a super cap, there is tons more Farads in a battery over a super cap... Thanks for you kind words, but a bigger thanks to Jonny who gave this to us.

Awesome! If only there were some easily formed yet smooth-solidifying plastic to make an ideally curved "dance-floor" so it doesn't rub so much on barriers. This is good RPM to start looking at Thane C. Heins' Perepiteia setup ;)

I have been watching Thane C. Heins with great interest, I have the transformer ( a door bell transformer ) Just need to hook it up. I have been thinking about just what you said. In times past back in the 1800's they used these magnets on like skate board ramps ( like empty swimming pools)

WOW !!! ausome. hope your wearimg goggles ! great to see a measurement of this set up, thanks

[marthale7]

That is a very good suggestion. Normally I use a plastic container ( an old chocolate raisin container to run this experiment when I goto high rpms, however in this case I did not ( slaps my hand ). If I do more of these I will take your advice. Thank you for good old safety advice it does pay to be safe when doing these experiments.

It seems to me that all you should have to do is take the frequency measurement and multiply by 60 and that should give you the RPMs. Like, 240 Hz equals 240 RPS, equals 15,000 RPM.

Batteries are not the same as supercaps. I have more storage in my big supercap than my batteries and, they charge fully almost instantly where a battery takes a long time. Carbon rods came from a company called Airgas, a welding supply co. They are online too. These are gouging rods, not coated. 1" dia x 18" long, about $20. And yes, thanks to Jonnydavro for all of his work. Lidmotor uses a concave mirror to keep his mag. centered. Low friction and great shape.

Thank you,

Bill

@ introvertebrate HA! :-) I am sure others have been here before me that have had this speed, might not lived to tell about it ha :-) Love your web site!

Show off :P

400hz ^_^ not bad
