Velocity measurement
Measuring velocity with a few resistors and a laptop-pc as data-sampler.
Airkannon build by Peter Madsen at Mothership.
We wanted to measure the velocity of the projectiles we where shooting.
How to do this with simple means?
- Resistors hooked up cleverly (Thanks to Christian Ravn)
- A 3v power supply
- Thin wires to be torn by the projectile
- A laptop for data sampling, using the sound-input and a recording program
-
- Velocity-measuring. Front end. Projectile enters here
-
- Pipe used to arrange the wires
-
- back end of pipe. Exit of projectile.
