Thanks for all the help we received with the Sonoran Science Academy-Broadway and BASIS Tucson TARC Teams at Desert Heat. Neither qualified for nationals, but it was their first year and they learned a whole lot. they now know what it takes to make it to nationals. I highly recommend SARA members to get involved, mentor, help start teams or anything you can do with TARC. It is a great experience.
We will be bringing teams from both BASIS Tucson and Sonoran Science Academy-Broadway rocketry clubs to Desert Heat 2012. Both teams will be attempting some official TARC 2012 flights.
Hi Folks, I placed a DH 2012 Poster and flyers in my Chiropratic's office. He has had a dozen+ enquires. I suggested a sponsorship banner $ 50 to $100, or/both a rocket with his logo including the motor cost, same price range. After DH he would display the rocket, with SARA courtsey note, with flyers. I can expand the offer, if others help building rockets.
I got the SubZero and Firerball, both by Leading Edge, (that's what happens when I don't tell my wife which one to get me for Christmas!) and the circuit and components are fairly straight forward. The LED is a 1 watt one from SuperBrightLEDs.com. The nosecones flash quite brightly. I also got the paralite for my scratch-built night rocket. Desert heat ought to be fun!
I launched my swing wing rocket this past Sunday and have posted the onboard video, along with a few stills, on YouTube. The wing is deployed by the altimeter at apogee and after flying it via RC down to a couple hundred feet, I command the parachute deployment to bring it down gently... Into a tree.

Swing-Wing Rocket Flight
Rocket launched on a G-64W Aerotech motor flys to 990 ft, deploys wing and is radio controlled down to a point where the parachutes are deployed.
I got to demo a ParaLite at Plaster Blaster this year. It is a system for lighting up your parachute from underneath upon deployment. It was quite effective and made it very easy to find the rocket (and to chase it as it was dragged along by the wind). It is a bit pricey but worth considering. Home brew designs might be worth experimenting with.
If you or someone you know works in Retail, the VERY BEST lighting circuits I have found come from store displays. They run for months on a tiny battery, and they are Very Bright! I'll be finishing a 18-LED rocket shortly running on 1 of these -- all night blinkage on a couple of flat lithium batteries.
For the DIY types (most of us I dare say) there are some simple schematics out there for wiring up LEDs and making them blink with simple 555 timer chips. I've built a couple of the commercial night kits and can share some of my lessons learned there too.
