Write problem/project Goal
To make a device that is capable of cracking the code of a combination lock.

My First Task
Explore methods to attach the solenoid to the lock.

Summary of actual work over first weekend
I attempted to find a way to attach the solenoid to the bottom of the lock using a three pronged hook.

Week1 Narrative
I attempted to attach the solenoid to the bottom of the lock so the lockpick would be more practical in a real world situation because if the lock was attached to something it would be difficult, if not impossible, to pull the arm up.

My Second Task
Explore methods for attaching the solenoid to the arm of the lock and find possible solutions to increase friction on the knob.

Summary of actual work over second weekend
I first attempted to use fishing line to tie the solenoid to the arm of the lock. I also used zip ties to accomplish the same task.

Week2 Narrative
The knots tied in the fishing line tended to slip, but the zip ties proved to be much stronger. Also, forcing the knob into position seems to hold it in place.

My Third task
Hook the switch up to the arduino and mount the solenoid to a piece of wood.

Summary of actual work over third weekend
I replaced the zip ties with an "S" hook.

Week3 Narrative
I found a suitable sized "S" hook to replace the zip ties. The hook is more durable and can be used multiple times.
