NSFW Machines

This channel has a engineering focus on DIY milkers, thrusters, pumps, vibrators (SCI style). Builds, materials lists, and code is slowly rolling out. 

It is incredibly important to acknowledge people who've put so much of their own time into building and sharing. When I started  machineyourself.com was the first place that gave incredible detail on the transmission, converting rotation motion from the motor to linear motion for thrusting. 

Above all was the Shagmatic by a man named Spencer. I didn't find this resource until I was already a few years in. But it was many years ahead of any machine on the market. It was able to change the position and length of the stroke while running. It has an amazing transmission using rollers. The control, again, was so far advanced. It's being used here: https://bulletprosthetics.com/
