 MISC - AMSAT CubeSatSims
- The orange one made from PCB's is sold. Still have one.
I have 2 CubeSateSims from AMSAT. One was from a kit and the other was built using PCBs from AMSAT. I sourced the parts and printed the frames for that one. They were fun to experiment with, but I'm getting away from satellite work right now so these need to go to someone who will use them. The kits are currently listed for $550 on the AMSAT website, when they are available. Mine are $300 each, shipped. Paypal, Zelle, check, money order.
