HDD as a motor.

[myposbussie]

I would say you need at least 8 AA batteries because an HDD normally gets 12v.

I have no idea what you are building but I will search on google sounds interesting.

I would love to see your final product and how you did it.


Cheers

This was the coolest and craziest idea I've heard this week.
Can't help though, sry. Good luck with it

My problem is solved I found a motor from a toy car (doh could have used one in the first place) But now I have this HDD motor lieing around.. Anyideas what to do with it? Oh and btw the vehicle I was planning to build is under 10 grams REALLY light in my opnion haha BALSA WOOD FTW. For all you that are googling what i'm talking about. Its a out of school activity called Science Olympiad, Event Battery Buggy .

Hey Keyreaper,

I found your thread really interesting and went to work.

I found a code that can make a stepper motor work from a printer port but now I need a "Borland Turbo Pascal compiler" Can you maybe help?

The code is:
Software to control Motors connected via a Disk Drive
Logic PCB to an IBM-PC Parallel Printer Port
The program assumes this cable design
program stepit; { Borland Turbo Pascal for MS-DOS }

uses crt;

const OUTREG = $378;
INREG = OUTREG + 1;

ALLOFF = $FF; { 1111 1111 }

NDS0 = $E0; { 1110 0000 }
NDS1 = $D0; { 1101 0000 }
NDS2 = $B0; { 1011 0000 }
NDS3 = $70; { 0111 0000 }

NMOTOROFF = $08; { 0000 1000 }
NMOTORON = $00; { 0000 0000 }

CLOCKWISE = $00; { 0000 0000 }
ANTICLOCK = $02; { 0000 0010 }

NOSTEP = $01; { 0000 0001 }
STEP = $00; { 0000 0000 }

procedure delay;
var i: integer;
begin
for i := 1 to 10000 do { nothing }
end;

begin { main }
ClrScr;

writeln;
writeln('***** Ian''s amazing motors *****');
writeln;

port[OUTREG] := ALLOFF;

write('All OFF to start with ');
readln;

write('Stepper Motor only - Clockwise ');

repeat
port[OUTREG] := NDS1 + NMOTOROFF + CLOCKWISE + NOSTEP;
delay;
port[OUTREG] := NDS1 + NMOTOROFF + CLOCKWISE + STEP;
delay
until keypressed;
port[OUTREG] := NDS1 + NMOTOROFF + CLOCKWISE + NOSTEP;
readln;

write('Stepper Motor only - AntiClockwise ');
repeat
port[OUTREG] := NDS1 + NMOTOROFF + ANTICLOCK + NOSTEP;
delay;
port[OUTREG] := NDS1 + NMOTOROFF + ANTICLOCK + STEP;
delay
until keypressed;
port[OUTREG] := NDS1 + NMOTOROFF + ANTICLOCK + NOSTEP;
readln;

write('Servo Motor only ');
port[OUTREG] := NDS1 + NMOTORON + NOSTEP;
repeat { just sit there } until keypressed; readln;
port[OUTREG] := NDS1 + NMOTOROFF + NOSTEP;

write('Stepper Motor and Servo Motor ');

repeat
port[OUTREG] := NDS1 + NMOTORON + CLOCKWISE + NOSTEP;
delay;
port[OUTREG] := NDS1 + NMOTORON + CLOCKWISE + STEP;
delay
until keypressed;
port[OUTREG] := NDS1 + NMOTORON + CLOCKWISE + NOSTEP;
readln;

port[OUTREG] := ALLOFF;

write('That''s all, folks ! ');
readln
end.


Any help will be helpfull.

ANGLE GRINDERS ARE DANGEROUS do not play with em u can cut ur hands off with it

Maybe if you're a spastic?

They're not that hard to operate safely!

Thread should be closed anyway as its been resolved....
Shame mods shame lolol.
As for the angle grinder although funny its not possible. You would need 240 volt not 24 guys and gals.
I think the original idea would have actually worked. Prob not real well but i think it would have and loved the idea.
Would have ran on 12 volts just fine and spooled quick as lol. Would have been a rocket had it been light enough. What 0 - 7200 rpm in a sec lolol.
