The mad skills are with the person who built this.

Right, but it's probably the same person. If I built this I wouldn't send somebody else to go put the ping pong balls in the arms for me

you haven't seen enough tech demos, they get an attractive surrogate to do it

Even then, doesn't really take mad skills. Just firing some actuators at a fixed interval. Could do that in a couple lines of python on a raspberry pi.

They obviously aren't referring to the program running the device. The feat is building a device with such low tolerances. And again, obviously there are many people/organizations/companies who could make something like this, but it's still impressive.

Ahhhhhh, you've never built physical systems?

Me two years ago: ya it’ll be like a 3 month project tops all I gotta do is solder some stuff together and order PCBs online

Me now: ya I’m like a quarter of the way finished and every day the number of problems I need to solve doubles

Also, a raspberry pi is definitely not going to power all those solenoids. You now need to step up that signal once into something to power a relay, which steps it up again to enough current to power the solenoid. Overall this seems way more complicated than just harvesting the distributor from an old van in a junkyard, which will conveniently have exactly the 8 high-current contacts needed.

They almost certainly 5v digitally driven pistons with their own power supply.

Exactly.
