So rocketry is a very careful release of the magic smoke?

The windmill published is a a water pumper. it need all the blades for high torque and low speed of teh pump transmission. Also why APRS? Why not one of the low power single chip systems like ESP-Now (ESP-32) or a nordic nRF7002 (many Mcu) all have node red support

On the APRS question, mostly because I wanted to - same reason behind my choice to use LoRa for most of the telemetry. Sending data via APRS and LoRa was so that I could play with stuff on our licensed frequencies that I was interested in, that would leverage some existing ham radio infrastructure, and with the idea of a longer range component to the data/communications. If the goal is strictly communication back to the ground station, pretty much any wireless protocol could be used that is good for line of sight up to several thousand feet.

The 12 year-old kid and I loved the episode, becuase it perfectly capture the two hobbies we have fun tinkering around with. Thank you!

I was also very interested to hear abou tthe 1 nF capacitor fix for AM pickup on the OHIS installation. The OHIS inspired morse code keyer and power cable here frequently has issues with AM pickup. I'm going to give the capacitoros a try.
