Nice Projects. This falls right into my expectations for a paradigm shift similar to pre-PC days. So much activity bringing down the cost of maker tools. Self regenerative tools even. You can use these new tools to help reproduce even better ones, taking down the cost of creating to unbeleivable lows.
For those of you old enough, you may remember being amazed that a 286 Clone PC in the early 80's was only $2000. It was mind boggling low. That would be about $3-4 K in today's dollars. Now you can get a decent desktop for $500 about $250 in 1980's dollars.
Truly amazing, Thanks for the links.
