I built an RS232 cable from parts from RadioShack 25 years ago, with no soldering, just electrical tape. It’s surprisingly easy if you don’t need speed. Mine capped out at 1200 or 2400 baud. Was it good? No. Did it work? Absolutely.

The quick adjustments to tileable blueprints sound amazing. Such a great idea!

Somehow I thought the pipette on water to get an offshore pump (like how you can pipette on an ore field for a miner) was already a thing. That and the quick access to landfill will save so much time when designing nuclear plants.

The spidertron stuff sounds nice too, but they’re usually so late game that I haven’t minded the slightly clunky v1.1 status quo.
