Description

Arizona Near Space Research (ANSR), a 501(c)(3) organization that promotes science, technology, education and mathematics (STEM) through Amateur Radio and High-Altitude Balloons (ARHAB) has supported NASA Space Grant programs since 2001. ANSR has conducted nearly 65 high-altitude balloon flights reaching up to 117,127 feet, many carrying student payload projects. Many more exciting flights which YOU can participate in are currently being planned.
A successful ARHAB group uses a variety of skills. These include:
-- APRS (packet), DF, DX, GPS, TV receivers, transmitters and multiple antenna types;
-- electronic and mechanical design and fabrication;
-- digital design and programming;
-- weather and flight path prediction; and;
-- many other STEM related activities.
If you're ready to roll up your sleeves and have some real fun while honing these skills, please join us! Hands-on participation by interested radio amateurs, non-amateurs and STEM oriented educational/student group participation is especially welcome.
Our regular monthly meetings are teleconferenced on the third Monday at 7:30 PM (0230 UTC).
For call-list inclusion, ANSR members should contact Jack (Pres.) or Elijah (V.P.).

Be careful of Xenon strobe lamps. They operate with bias voltages of 300V or more, and use several KV ignition pulses. At low barometric pressures, voltages

The strobe is a great idea! I'll be sure to get one and attach it to the bottom of the payload. I can just imagine the reaction we will get if it comes down in
