Default Re: Web shooter shop class - Part 2

To answer spectacular23's questions from the formula thread, I used a solenoid, the spinerette, and some solid pieces of tubing. Basically, the formula is constantly shooting into the spinnerette, building pressure in it. However, when equilibrium has been formed between the small solenoid compartment and the larger canister, the shooting inwards will stop, keeping the formula in stasis until I shoot. When the solenoid opens, it goes into a small piece of solid tubing. That solid tubing connects to flexible tubing, which connects to a small piece of solid tubing, which contains the solenoid. The solenoid is controlled by a relay which is controlled by a microcontroller.
The solenoid, on the entry side of the formula, has a needle which pushes in a spring-loaded valve on the canister when it is screwed in.
