From Home and Local Store: Cardboard, connecting wires and an old USB cable.

Step 3: Prepare the Motor

  1. Cut a piece of thin Cardboard of about 1.5cm x 1.5cm.
  2. Using Hot Glue, Paste the cardboard piece on the DC motor.
  3. Paste a toggle switch at the centre of the cardboard as can be seen in the attached images.
  4. Cut a USB cable from the end opposite to the USB plug.
  5. Identify the power wires out of 4 wires in the USB cable (generally of black and red colour) and also, identify the data wires.
  6. Cut both the data wires as we will only be using the power wires in the USB cable.
Note: You can also identify the wires using a multimeter (in conductance mode) as the PIN 1 and PIN 4 are the power pins on a USB port.

Step 4: Make Connections

  1. Connect a wire from the USB cable to the toggle switch.
  2. Connect another wire from USB cable to a motor terminal.
  3. Connect a IN4007 rectifier diode in forward bias between the remaining motor terminal and the toggle switch.
  4. Attach the Mini Drill chuck on the motor shaft and tight all the screws using the provided Allen Key.

Note: In order to protect the USB port from the back EMF (Electromotive Force) of motor, it is important to connect a rectifier diode to the motor terminal.

Step 5: Test Mini USB Drill

  1. Insert the drill bit of required size in the mini drill chuck.
  2. Connect a mobile powerbank (or a mobile charger) as a power source.
  3. Our mini USB drill is ready to use.
