Remove the battery from the drill, and place it aside. This won't be used for this project, but you may wish to save it in case you ever wish to use the drill again. On the wire leads that connect the drill to the battery, identify the positive and negative wires. If in doubt, check the markings on the battery, or test the charged battery using the voltmeter to determine which terminal is positive and negative. Now, connect wires to the positive and negative leads.
Connect the opposite ends of the positive and negative leads to the car cigarette-lighter plug-in Dell Latitude C840 AC Adapter. This will give you a 12v outlet to plug any DC device into. Install a 10 amp diode between the drill and the outlet. This acts like a one-way valve to prevent the drill from attempting to use the laptop's battery power to spin itself. You may also wish to wire your voltmeter in serial with the flow of Dell Latitude C840 AC Adapter power to measure how much electricity your cranking is producing.
Plug your DC to Dell Latitude C840 AC Adapter into the cigarette lighter outlet. This will provide a normal, household style, 120v electrical outlet to plug small appliances into. Any other device that has a 12v power outlet such as a cell phone charger can also be hooked up to the cigarette lighter outlet, avoiding the need for an inverter.

Things You'll Need:
Any 12v power drill
Old-fashioned hand drill
DC to AC inverter rated at 120 watts or more
10 amp diode
Voltmeter
Car cigarette-lighter plug-in
