Spaaaaaaaaace
summary
Claims concrete numbers like 29.6 megajoules per kilogram to reach orbital sideways speed and ~17,000 miles per hour for low Earth orbit, notes equatorial launch saves ~1,000 mph, and compares the Apollo guidance computer to an iPhone 5s with a specific multiplier. Describes built hardware and experiments: a prototype lunar miner and an on-orbit experiment, plus a Kerbal/HTTP-enabled part and a Ruby PID controller that actually hovers at 150 meters with minor lateral drift, code hosted on GitLab.
