You can make a ballistic pendulum for almost nothing. Shoot the pendulum, measure how far it swings, do some maths and out pops your muzzle velocity.

Not to be a pain, but you could at least out some links to help with those equations...

One thing that may work, mythbusters once used stick-on accelerometers. You can buy them for cheap, in large numbers and different levels of resistance. You could put a piece of wood and put some on it, then shoot it. That might work. Hope i helped!
