hauska projekti. ite väsäilin joskus X vuotta sitten moisen vanhasta segatesta. Ja myöhemmin tehty toinen kehitysversio oli rakennettu kotelotuulettimesta. Pikku vinkkinä, siinä on vääntöä enemmän kuin kiintolevyssä.

Harkitsin tuuletintakin mutta tuo tuntui geekimmältä versiolta. Tuuletin olis parempi myös siinä että kyseessä on normaali-, eikä askelmoottori jolloin hommasta sais yksinkertaisemman ja jopa säädettävän.

Ehkäpä etsin jonkun ylitehoisen Deltan seuraavaksi ja askartelen siitä jotain :)

well.. Moder told that he had done both HDD-grinder and later verison based on a fan motor. HDD-motors are steppers so they are harder to control than normal DC-motors. Moder also told fan motors have more torgue than HDD-ones which is pretty obvious.

Sattu olemaan tänään täällä atk-liikkeen perällä huoltohuoneessa hieman tylsähköä ja sattui löytymään rikkinäinen kovalevy. (ylläri?)

Huvikseni katselin metku.netiä ja huomasin HDD Grinder artikkelin ja olihan se pakko kokeilla.

Aivan mieletöntä :D

Ehkä laitan videomateriaalia jossain vaiheessa jakoon :)

EDIT: Tässä osoite videoon: http://kiksu.headplug.com/hiomakone.wmv

Hyvin teroitteli ruuvimeisseleitä :)

Nimim. töissäkin voi olla hauskaa!

Synkroni moottoreitahan nuo. Vanhemmissa SCSI-sirkkeleissä on vähän isommat piirit niin niiden jalkoja voisi saada helpommin kaivettua ylös piirilevyltä. Sillon vois onnistua se nopeuden säätely.

i just tried this mod, but with a "quantum bigfoot" drive, it had a small capacity, so is useless to me, and as its a 5.25" drive logically it must have more powah.

however, after about 5 seconds, the thing spins down, is there a way to stop this? or have i just trashed a hard drive for no reason?

thanks in advance!

Ouchie. I actually had that prob with my version too but not quite as bad.. I think there might be a pin in the ide-connector to help the drive to spin constantly without slowing down but using it is easier said than done.

i think i have just found a solution! (kinda)

if you short the two rightmost (your right, looking at the connector face on) pins on the ide connector (yes, i did find this out by randomly shorting pins) with a jumper, while it is spinning, it will not spin down.

however, if you place the jumper on there before you power up the drive, nothing will happen.

however once the drive has spun down, if you connect the jumper, remove it, and then re connect it, it will stay on, creating a sort of switch indipendent of the power supply.

now i just have to find some sort of switch that will go "connect, disconnect, connect" when turned on :roll: any ideas?
