We’re using the 43oh to control 12V solenoids supplied from a Dangerous Prototypes ATX breakout, and the Adafruit flow meter is feeding back position data to the 43oh. Surprisingly IT WORKS! For more build deets visit the blog
Check out the video after the break.
He should provide more specs about that cylinder – if we assume that cylinder is 6cm diameter then we get roughly 14.1ccm volume per 5mm stroke (that’s what he could achieve). Now that does sound impressive until you realize that for a 1.5 cm diameter the same 14.1ccm translates to 8cm of stroke. Though sticktion would make it more of a problem for smaller diam. cylinders so it’s going to get worse.
It might be a better idea to investigate Hall effect sensors instead. Try ss495b
Thanks for the tip.
3″ diameter. sticktivity is an issue, but I still got a few trick up my sleeve.
