Hello All,
Here I have tried to run the hard disk with IC 555 and IC 4017 and motor controller IC L293D
The idea is simple ,
Hard disk motor requires 3 shifted pulses to run.You can get information about the stepper motor and running machanism in some other article of instructible.
Requirement
- 1 nos ,salvaged hard disk motor
- 1 nos ,555 IC
- 1 nos ,4017 IC
- 1 nos ,L293D IC
- 4-5 nos ,LEDs (optional) I used then just as a indicator
- 1 nos , 100 K Pot
- 4-5 nos ,1 K resistances
- 1 nos, 1uF capacitor
- 5 v Supply (I modified the mobile charger else you can use 9 V battery )

In screenshot is the Hard disk Motor , I connected 3 different color wires to identify.
1- Red is 1st pulse
2 - Green is 2 nd
3 - Black is provided with 3 rd pulse

I was initially thought of using Arduino for same purpose but then I wanted to minimize the risk using an expensive chip and also dont want to use arduino to just rotate the motor ;)
I thought of using IC 555 to supply the pulses and using the night rider circuit to supply 3 shifted pulses to motor.
Circuit diagram is attached
Here is the working video,
