OK, just to start this out, this may be a really crazy idea, but we wouldn't get anywhere in this hobby without them. I'm trying to do my part.
Hold on to your desk....
Dual deployment without any pyro or regulated items whatsoever.
Well, my problem that started this whole thing was that us NAR Jr. L1 people can't use black powder and ematches because they are regulated, and we are obviously not 18 or older. This got me thinking to Air Command Water Rockets who I recalled had a non-pyro method of deployment.
They made a video (here) which I thought would be a good reference point. Everything seems straightforward but...( and I'm looking at you, robotics or R/C hobbyists)
a. I don't have a timer like the one in the video and...
b. I don't know much about servos. Well, a little, but I'm still fuzzy on some of the basics.
So, right now, I'm trying to find a way to get a similar assembly without spending too much money. My current (loose) plan is to purchase a servo, a servo controller, and an altimeter. I plan on connecting the output of the altimeter to the input in the controller, which will trigger the servo motor to turn.
So, a few questions to ANYONE whom knows much about servos in general.
a) How can I hook up a servo to a deployment charge? I know that they have a special cable, so should I separate the power and the ground cables from a connector, so I can still disconnect it and program it?
b) Once a motor is programmed to work at the right speed for the deployment charge, does it stay programmed in that way after you disconnect the power? Basically, would I need a special servo controller inside the rocket in order for the servo to work properly?
c) Lastly, would you allow a 14-17 year old to do this dual deployment with a high powered rocket?
Note: I know that there probably many other young'uns like myself who would be interested in this, and many other people as well, so I plan on documenting my tests and my new knowledge acquired with this form of deployment. One of my personal greatest disappointments with the NAR's system is that I can't do dual deployment. I'd like to help as many other people as possible.
Also: I plan on only using this for the main deployment, I'd only use motor ejection for a drogue. If this turns out to be reliable, I might consider using a full dual deploy system with this.
Thank you so much for your time and replies in advance.
