Step 4: Making a Hand-Crank Generator

Picture of Making a Hand-Crank Generator
Step 1: Remove the battery from the cordless drill and look up inside.  You should see 2 terminals where the battery provides power to the drill.

Step 2: Use the aluminum foil to fashion make-shift wires that connect to the terminals.  (Salvaged copper wire is even better if you can find some).

Step 3: Secure your drill to a surface like a piece of 2"x4" with the trigger pressed "on".  I used plenty of yarn to hold it down tight.  

Note:  The trigger needs to be on, and the torque setting at it's highest.

Step 4: Insert the mixing beater into the drill chuck and make sure it's tightened so the beater won't come out.

Step 5: Add the salad fork through the mixing beater to act as a crank handle, and hook up your charger cable.  Hook the red wire to the positive lead, and the black wire to the negative lead.

Note: Polarity DOES matter!  If your battery isn't charging, you've probably got the polarity reversed.  You can either switch the cables, or set your drill to reverse and crank the opposite direction.  This will reverse the polarity you generate and should fix the problem.
