Mid-term project proposals and LED flashlight circuit

here are my 5 initial ideas for the mid term project:

machine for breaking wood - (not pictured = piezo microphones attached to the base of each 1x1 to pick up the sounds of the wood cracking and bending).

Also, Im pretty sure I can find a relatively cheap "wench" or "bait-and-tackle" on craigs list (i.e. the kind that go on the front of trucks).  then I would simply need to get various sizes of pulley's and extend a drive shaft off of the 'wench' for each of them.    EASY!

 This idea I do not like.  I like an aspect of it--that of submerging video electronics into mineral oil-which does not conduct electricity (giving the appearance of being submerged underwater).

like that, but not for this sort of kinetic project.

 I do like this idea, but also perhaps not for this project...  a summer project/collaboration with another film student (for i do not work in film proper).

 I like the top idea of this one, I was looking at gears at science and surplus this weekend (not a whole lot of selection).  I would almost rather just cut cogs out of wood for this instead of using plastic or metal gears.   Im pretty sure that would be do-able (allowing time for trial and errors of course).


the  bottom idea I like, but... nah.  a little risky attaching metal worm-screws near the yoke of a TV.... lots of voltage... could arc.  forget it.

here is what the circuit layout of my RGB LED flashlight turned out.  I could have made it more compact, but this allows enough space to actually adjust the RGB pots, and also hit the button (not pictured...  this is actually a scan from my printer, I can't seem to find my digital camera, sorry).  The flashlight works great except for the 'red' pot---it jumps a bit, so Im going to replace it eventually.

I think Im going to give this to my fellow film grad Elizabeth, she just made a beautiful film of just shining LED's onto film in the dark room.  She might want to screw around with this adjustable one?  we shall see.
