An aerospace engineering team at Cornell has an ongoing and already funded kickstarter for the Kicksat, which is a cube filled with 300 or more even smaller Sputnik-type "I only beep" ultra-mini satellites. Each person who contributed gets to name their little piece. It's a very cool engineering project that's been going on for 3 years, and looks really, really solid. Better yet, it's met its funding goals, so it's got great prospects. Go visit and see if you want to participate!
And, a person named Jaanus hunted up the writeup and spec for PCBSats, a super-tiny satellite 1/4th the size of a Cubesat, consisting of, basically, one circuit board + 2 solar cells + tape.
Jaanus's blog is worth reading for open space hardware fans in general, as his goal is to help find then share build/make techniques from other small satellite makers.
Until next week,
