I was recently given a new, relatively expensive (~$900), mountain bike and would like to ride it to and from campus every day.

I have a good U-lock with an auxiliary cable for locking the front tire. It will only be locked, properly, outside the building where I have classes from about 8:00 AM to 5:00 PM (this is a relatively high traffic area). Outside of those times it is locked inside my apartment.

The bike is registered with campus and the local P.D. and has my name etched on most of the components.

1) Is there anything else (besides not riding it) that I can do to keep the bike and/or components from being stolen?

2) With just the things I have now how safe should it be?

I am on the University of Colorado at Boulder campus.

Thank you in advance.

I have a DC power supply that has controllable voltage between 0-100 V. I need to generate 40 kHz alternating voltage at about 3 V (the frequency and voltage have a tolerance of 10% on either side). This voltage can either be sinusoidal or square, it does not matter for my application. If it is difficult or expensive to convert DC all I need is the alternating voltage so how can I do that?

My budget is around $150.
