- You need
- CD drive, from old computer
-3 volt battery pack,
-3 volt momentary switch
- Insulated wire
Step 2: Un Screw the Case
Be careful, and SAVE THE SCREWS.
Step 3: Locate the Positive and Negative Terminals
On the circuit board, you will see 2 large solders, which are above what you may be able to see as the motor. This should be towards the front, where the CD comes out.
Step 4: Re-Melt Solder
With your soldering iron, re melt the solders, and insert wire into molten solder, one positive and one negative. Make sure that you strip each end BEFORE soldering. Also be sure that your wires are long enough to reach OUTSIDE of the case.
Step 5: Solder the switch
Solder one of the leads from the motor, directly onto the battery pack's lead. Making sure that the positive or negative cooresponds to that on the battery pack. IF YOU DO THIS WRONG IT WILL NOT OPEN. TEST TO MAKE SURE WHEN VOLTAGE IS APPLIED, THE TRAY OPENS. Solder the other lead, from the motor onto the switch, and the cooresponding lead from the battery pack to the other terminal on the switch.
Step 6: Attach the Circuit
Glue the switch as well as the battery pack to the side of the case as i have shown.
Step 7: Re Assemble
Re-assemble the drive with the screws from step 2.
