Tons of questions, this is incredibly cool! Can you discuss:
1.) How you compensate for anode consumption/geometry changes over the lifetime of the anode. For instance, does the center get worn away or do you try to uniformly use each "pixel".
2.) More details on anode "pixel" geometry and minimum feature size.
3.) Can you talk about the development process? Did you have in situ measurement, or post build analysis of the part and anode.
I would imagine resolution mostly comes down size of electrode and how close you can get that to the substrate and grow the deposit in a controlled fashion. Mine were 25um. As for wearing out the electrode; madden's paper probably has some information. I would expect the wear to be similar to the oxygen side of electrolysis (water).
Rejection of neighboring HDD vibe disturbances is already an issue, so fascinating to see what their control approach is. In my limited experience, mechanical HDD control is near top of the game for electromechanical positioning.
At least they know what all the heads are doing so could design them to cooperate or model/predict the disturbances pretty well, unlike for external vibrations from neighbouring disks.
Agreed re: mechanical HDDs being engineering marvels. The positioning performance at the price/manf volumes is really incredible.
As the poster below mentions, neighboring actuator coupling/disturbance rejection is very much a performance consideration (even between neighboring HDDs) and then to package all that additional complexity into the same form factor is really something.
It'll be interesting to see if this sticks around, or the added complexity makes it short lived.
this is definitely not intentional and is probably some combination of me doing a bad job of setting up webrtc, people having spotty internet, and people messing with the site.
I like Boston Dynamics' Stretch as a general solution, but given the sheer volume of standard loading docks/trailers, optimizing loading speed and density with a specialized solution feels (ooof) right.
