Time: Dependant on type of lamp or base you have/ decide to create but generally they take me somewhere between 6-8 hours, a great weekend project.
Cost: Dependant on materials, the base costs me $100 to make at a metal shop. If I go with CF lights it will cost less than $10.00. In this project I will be using LED strips because my cousin wanted one where the color changes . You can get LED strip kits for about 50 bucks.
Skills needed: Basic soldering and electronics will be an asset. Welding if you choose to make your own base.
One of the most difficult parts of this project will be making a sturdy enough base so that it cant be knocked over easily (they are very heavy...). The ones I had came with a stand that was wallmounted at one point but I didn't want to use heavy hardware to attach them to the wall. I made a shorter lighter version and 2 taller "fullsize" versions that use some heavy steel. As for the rest of the project there is basic soldering for the lighting, cleaning, and getting everything to fit! if you have a key already you can skip the step where you disable the lock cylinders. The cylinders need to be disabled so you can easily access the bulbs if they need replacing and you can also get to the money compartment where I like to stash all of the wiring. It can also be a fancy hidden compartment!
