Can't seem to get enough of your teaching, I have watched this video maybe 10 times already, but it is not enough, I have ordered the items I need to build it. Will build it then let you know the out come of it. Thank you so much for these videos.
I know what you mean, I love being in my workplace as well. Little jealous on all your knowledge and equipment tho....... But that’s why I’ll keep watching your videos. Huib
Your setup looks so much more professional than mine. I originally thought mine was going around 5000rpm when i maxed out the bearing, but after watching this and hearing what yours sounded like running at 5000, im starting to think its more like 15000 or so (i still have no method of measurement) because mine sounds like a dremel at maximum speed. Im really looking forward to the arduino tachometer even though i have no arduino experience. I think im going to try making a more efficient version next because my current setup using ~35 turns of 16awg magnet wire draws about ~30 amps constantly so i use a massive 15x25cm heatsink on the mosfet so i can run it for more than 10 seconds. My plan is to make the more efficient version run for at least a week on a couple of AA batteries at very low rpm. I think it might be fun to have it just constantly spinning on my desk
It sounds like you could be at 15,000 RPM! Keep us posted on your experiments and I'll make sure I follow through on the tachometer - there are some notes on it on the web page right now but I need to do a video. dave
Hi Dave, I am going to order Pro Mini - ATMEGA 328P - 5V 16Mhz - Compatible Board, but I don't see a socket to hook up to the computer to download your program.
Ralph - you need a USB to serial adapter like this www.amazon.com/HiLetgo-FT232RL-Converter-Adapter-Breakout/dp/B00IJXZQ7C/ref=sr_1_5?crid=3RAGW666O7CKA&keywords=pro+mini+serial+usb&qid=1661003595&sprefix=pro+mini+serial+usb%2Caps%2C72&sr=8-5 dave

I've found that my fidget spinners turn into a pipe bomb at just over 5400 rpm. I use a program called SimpleDyno (google it) for my rc cars and it's fairly easy to adapt it to this. So far I've hit .8 HP @ 5400 rpm, then I shut it down. I use red bones skate bearings because the stock bearings are trash. If you try this I strongly advise building a plexiglass shield as I have had 2 of the plastic housings break apart and those magnets fly out like bullets.. heh

You are quite welcome, Ralph - enjoy!

I was inspired after watching your video , and tried it out myself and thanks it worked.
That is great news - thanks for letting me know!!!!!
I would also like to see you build an axial motor with full explanation: looking forward to see it in the near future
Great videos Dave

Hi Dave, I love the project! Very informative and fun. Thank you! I look forward to any more projects you think of.
I enjoy you videos. I'm a teacher and will try to duplicate some of your work in class. I think students will like it.
That is great! Please let me know how it goes.
thanks
dave
I just love your lab! Great video as always👍
Thank you, Huib - I spend many enjoyable hours working in the lab......

Hi Dave, found one with a usb. NANO V3.0 Development Board - Clone Compatible Model. Thanks
Já tenho meu spinner na época kkkkk
Sir, could you possibly make fidget spinner Bedini motor ? Would love to see how it works out and if it's possible to charge battery with it.

Try using 3 coils connected in series. You could easily expand your setup while trippeling the acceleration force.
Interesting idea - May give it a try - thanks!

No dinamometro que chega quantos quilômetros?
I think I'm going to use this information to try to make and electric powered longboard. Will keep updates of process
Please do keep us informed, Anthony - good luck!
dave
Really cool 😎
Awesome.
Can you recommend a simple brushless motor build for my STEM class?
Patrick - I don't know of any kits but there surely isn't a much simpler way to build one than what I have shown. Give it a try!
dave
I am using one coil at 12VDC getting 700RPM I dont use h-bridge, powered coil via High Side Switch
Good work, Mangesh - thanks for letting us know
dave
Is 10000 rpms next?
Didn't you say in one of you videos that you taught at a high school?? If so what was the highschool

@@DaveBodnar thanks for replying, I don't live near Pittsburgh, but I heard about it. and I'm in the 8th
Spinner com som parece um gol ap turbo na alta kkk

Coloca Hondata VTEC no spinner
Well then. That was interesting.
Coloca ele no dinamometro
