I know there are no electronics in this project, yet, but its still pretty awesome(right?). I needed a pneumatic bearing press and I didn't want to spend the $3000 that they cost, so I built my own.
I had a pretty successful Kickstarter and I have 8000 fidget spinners to install bearings in. I know better than to try and do it manually. I would be hurting. This installing will help out a lot.
Im-press-ive work :-)
Might not be electronic, but it is using a AND gate for safety. Nice... :-)
