Around the 2010s there was a surge in projects that aimed to publish open (and often made for being easily manufactured by hobbyists) hadware designs. There were project in virtually every domain (cars, lab hardware, satellites, etc). We had amazing projects like OpenPCR, OSE, etc. The movement did not exactly disappear, but a look through most of the project of that time show most of time slowly declining, with still alive (in name at least) but getting minimal amount and not making much progress. I expected much more given the amount of enthusiasm back then. Can anyone explain to me why the movement underdelivered so much ? And I'm currently seeing a spike of open hardware projects these days: do you belive we are seeing a comeback ?
