All you'll need to do this project is:
1. One (or two) old free standing speakers, the bigger the better. Preferably in good aesthetic condition, preferably broken, and preferably free (I gave myself a $20 spending limit for mine).
2. A hand saw
3. Some hinges
4. A claw hammer or crowbar
5. Some paint
6. Planks of wood (to make shelves)
7. Screwdriver or a power drill
8. Roughly 2.5 liters of pure, unadulterated gumption. Feel free to replace with true grit.
I also used a rotary tool, but I'm sure you could pull this project off without one.
