Hard Drive Stepper Motor as Rotary Encoder

[Stoney3K]

Slap on a 7" vinyl and you've got a good DJ controller.

[pemigama]

:o nice

[pzero111]

ipod click wheel?



[fsigo]

I would love that as a digital volume controller.

[killerob666]

What is the point of that device?

[stan464]

@killerob666 Thoughts exactly.

[CSpannerz]

instructions to make? ^^,

[ffleurey]

@CSpannerz See the link in the description :-)

[fabiuh991]

will this work with arduino?

[ffleurey]

@fabiuh991 Yes, no problem, the controller I use is the same kind as on the arduino.

[ravenjoey44]

you should make it into a combination lock or a wheel of fortune game

[ffleurey]

@jose1791 Brushless motors and stepper motors are basically the same thing as far as I understand. Usually we call stepper motors brushless motors with a large number of poles which allow them to be controlled in "steps" (which is not really the case for the hard drive motor).

Nice Job :)

[2001v8244]

now make it play that back...



[Nomoreidsleft]

@2001v8244 Yes, then it would be like the Big Wheel on The Price is Right. They could pretty much stop it at any number they want. It's got a microcontroller on it too.

[AdjewareZ]

the iTouch 5gs

[bejius]

Ho waw, it looks like a dial from a spaceship, Im sure you're using pwm to fade the LED's rigth ? Personally I whould use it to make a cool dimmer for my bedroom ligth.

[ffleurey]

@bejius That's right, PWM it is :-)

[meinotherside1]

very nice!!

[chiptechsmith]

Excellent idea. The web link is still broken but I would like to see it.

[gamingSlasher]

The link you show goes to a page trying to scam you with virus checking.

[ffleurey]

oops, sorry about that, my web page has been hacked... It should be back now.

[poppinoncrackvideos]

Can I have one

[WiKKiDWidgets]

aha! I knew I was hanging on to those old HDD motors for something! Now I've found it. I bet this could evolve into a CNC machine Pendant... Hmmmm *evil grin*

Thanks ffleurey!

[msilveirabr]

@WiKKiDWidgets I totally agree! I have many of those too, the pendant was the second thing in my mind when I saw this video :)

[hootergirlsrhot]

sounds like the clicks on an ipod

[Nanovirus5995]

Cute device and all, but what does it do?

[hameeds01]

does this motor has feedback hall effect sensors ??

[macospat]

want!

[uploadJ]

Very cool; I looked at your circuit and code too; Very cool idea.

.

[etmax1]

looks more like a hard drive spindle motor which is a BLDC motor, not a stepper. BLDC motors have integral hall switches (usually)

[Streamtronics]

haha, this is cool xD

[onionofdeath]

That is cool!

[YoshiProgrammer]

Cool!



[LolitsDeformed]

maybe you use that in spin the bottle (or spin the harddrvie platter motor thing)

[pikachuthesquirtle]

get a life.

[mremgee]

that'd look soo nice as a combination lock for a safe!

[karlmonster]

how many steps are POSSIBLE ????

[SROCB]

hehe the new pionner cdj-400

[rajithaify]

wow that's neatly done. congrats!

[flow2fly]

Cool thing!

What was the harddrive you used?

[Twistx77]

GREAT Idea!

[Jonsei]

wow this is awesome! i'll build one as soon as i get a similiar opamp.!

[Pudersepp]

Neat!

[produKtNZ]

You could use this as an improv item to a game of spin the bottle :D

Awesome xD

[zlwilly]

That's one of the coolest little homemade hack-together's that I have ever seen. Kudos.

[ffleurey]

Thanks for your comments. I have posted some more details on how it works. See the link in the video description.

[fernandoae]

Estás usando los sensores de efecto Hall? o las bobinas y operacionales?

[guyshr5]

i want to know how u build this if u can re build and show here is youtube i be happy or jusy write how u build this tnx

[Fredasp]

very nice job!

How did you 'read' the position? Hall effect Sensor? or ADC in the terminals of the motor?

Post in somewere at least the way please?

thank you.

[RoxasKH56]

@Fredasp I doubt he read the position at all, it seems as if it could be stored easier.

Seeing as how there are 8 leds I guess each position could be made up by using a variable to store input from the motor. Now, this assumes that the motor were to give back input in degrees.

int R; // motor feed back.

Each position would be equal to (R%(360/8)).

Obviously, when the motor spins in a positive direction it will increment, and decrease in the opposite direction.

[solorstars]

nice just make a combination program chip and stuff like that to make an electronic safe

btw do you have the prints or diagram to make that i want to try making that :)

[30GB]

useless and yet so fun to play with lmao

[svofski]

Super-awesome! But this isn't really a stepper motor,but a brushless motor if I'm not mistaken. You made it work nevertheless, cool jog dial.

[PilotoMAF]

Does the led fade-out "effect" is due to motor indutance or you made it in your project ?

It might not work in high rpm. The led will not turn off ...

[AMVDawg]

If they could be bought I would buy one. It's so cool.

[laustend]

Amazing... would you be willing to sell plans to make this. I would LOVE to have this as a widget on my Desk to play with

[cheetawolf]

cool, its just like an ipod's touch wheel thing :P

[doggiedoc94]

Cool! I've been looking for ideas to use old drive motors for. Can you post more information?

[Ajjojm]

This is awesome!! I'd love to use something like this with an arduino.
