Modifying a hard drive to spin at 51000 rpm

It would be interesting to make a remote-controlled airplane with a hard drive motor.
ESC:
amzn.to/3ejpBjL
Power Supply:
amzn.to/3x8tLnb
Function Generator:
amzn.to/3n7bQIK

So this is how an SSD work? "Super Sonic Drive" :P

[@Jsino_6651]

Lol

[@Team_Reaper.]

Solid state drive lmao

[@JB-mk4ry]

Be careful lol... Those things will do decent damage if the platter breaks apart and becomes shrapnel.

[@TannerTech]

Yeah, I had safety glasses on. That probably would not be enough to stop all the shrapnel though haha

[@lennyvalentin6485]

@@TannerTech You had safety glasses over your mouth, throat, stomach, d--k, crown jewels...? >:) High velocity shrapnel is EVIL. Especially plastic, as it tends to splinter into tiny fragments (due to brittleness/low strength) and is hard to find during exploratory surgery as it won't show up on a metal detector or such instruments. I'd suggest a decent sheet of plywood inbetween you and crazy-a-- experiment, or at least not direct line-of-sight. ;)

[@TatsuZZmage]

Oh boy oh boy, are we gonna see a "Rapid Unscheduled Disassembly"?

[@apieceoffabric294]

The minute that thing shatters when it's flung off, my man is gonna get turned into swiss cheese lmao.

[@ItsMePhiliph]

lol, that weird sound at the end was... kinda scary, but for the jokes could be interpreted as plane engine failure and eventually crash on a mountain :D

[@marwi16a53]

Usual hard drives for home users spin at 7200RPM, energy saving drives at 5400RPM. But you have a server drive, those spin at 10000RPM, and yours is even the fastest at 15000RPM

[@thegeforce6625]

the hard drive your messing with spins at 15,000rpm normally, those 15k drives have 2.5" platters in a 3.5" case for heat, turbulance, and access time reasons.

[@treasuretotrash2067]

If you were to replace the bearing do you think it could reach maybe 70,000 rpm? :P

[@TannerTech]

Perhaps. I also probably could have if I had a larger power supply and a better ESC.

[@BoBaH_BoBaHoB]

72k RPM will be good.

[@MyHandleIsGood]

But how fast is the read and write speed?

[@gabri41200]

at this speed it cannot be read or write

[@TannerTech]

True

[@alpogant1071]

if you can't afford SSD:

[@TannerTech]

Haha, true! get those high data speeds and limited lifespans

[@phonotical]

You maybe need some longer leads so you can experiment at a safer distance 😂 putting a cover over things is a nice idea if you don't like the thought of metal shattering and launching itself into you

[@NerdlabsSci]

Cool project! nice job tanner:D

[@Muzzaymann2260]

Thanks for the help, but how much power supply you are using at that crazy speed.

[@Omari1125]

How to get SSD read and write speeds on a mechanical harddrive.🧐

[@aunabreslingaming3279]

My God that is literally vacuum level you bet your bottom dollar that is a 1980 server room at its finest

[@yuk1c]

hdd overclocking

[@arbiteras]

If it was stabilized to work normally, it would be faster than ssd, right?

[@bhxlegend]

No never ssd literally pull and push electrons to read and write no mechanical drives can do that plus just to run it at 50k rpm you'll need somewhere around 4amps so not worth it 😂

[@ghostrider-be9ek]

holy christ, you should be no where near that thing, ESPECIALLY on the plane on rotation

[@davidledoux1736]

"Wow! That thing is loud." Lol! You should have measured the decibel levels, as well.

[@TannerTech]

Yeah, haha. My mic didn't do it justice. It sounded about as loud as a blender

[@davidledoux1736]

@@TannerTech Very cool video. Thanks for sharing it with the world!

[@sharonbraselton4302]

bkenders not too luod like cincred ßinc bim just loder thr normal bit not terbal

[@phonotical]

I'd like to have seen it in actual operation, reading and writing, but with the speed being entirely manual

[@TannerTech]

I would as well, although I do not think that would work as it would have to sync it's reading with the rotations of the disk. The circuit would not know the speed under manual control.

[@bhxlegend]

Where you are not uploading from last 2 years? Can we get a free esc from hard drive motherboard itself that was used to run the hdd motor when it was working?

[@rav_6602]

You should hit up electro boom for a fancy oscilloscope

[@TannerTech]

Good idea! I found this one in the trash and fixed it up. I commented on electroboom's channel to win a scope once, but did not win it.

[@JB-mk4ry]

@@TannerTech Medhi definitely has an "in" with Keysight. IIRC he's on reddit somewhat frequently, maybe hit him up for a collaboration?

[@_a_v_j]

That would be EPIC to see them talk.

[@ericgulseth74]

@@TannerTech Where do you find oscilloscopes in the trash?

[@Phamy3410]

Imagine if you make it so fast it needs oil and goes faster than ram

[@computeraidedworld1148]

What about slowly increasing the speed of a working drive that is reading and writing. To see how long it actually works till it doesn't like the speed.

[@TannerTech]

That would be interesting to see. Maybe I need to go grab another hard drive haha

[@Athisproductions]

do you think you could put a prop on it?

[@JohnUsp]

Would be nice if you try to read the data.

[@chaudry123]

Wow

[@davestech6357]

Normally the esc works 0 to 5v to change the speed. Did you just connect the generator to the center wire and ground?

[@TannerTech]

The ESC uses a PWM signal that switches between 0 and 5 volts 100 times per second. The ratio of the time it is at 5 volts and the time it is at 0 volts(duty cycle) determines speed.

[@TannerTech]

I connected the hard drive motor to the 3 wires. It doesn't matter which ones
