Unfinished business

The idea with this was to eliminate the need for rubbing by shaking the lens case for 12 hours every day. This wasn't possible with motors because any consumer motor would quickly burn out. Direct drive magnets banging on it were extremely noisy. Only a floating magnet could do the job.

After using noisy impacting magnets for 2 years, the need to continue this project resurfaced with R.H.II sleeping over.

The original idea was to levitate the contact lens case 1" below the magnet and shake it up and down over a 1" distance. Found the magnet required to do that would have to be enourmous.

1 year later, broke down and made a suspended version. Here is the latest prototype. Only weeks of continuous use will show if it's powerful enough. Then we can build a pretty version. Insufficient agitation makes the lenses uncomfortable over time.

Now a movie of the latest agitator prototype.

Oh, man. That is quite the project. I guess you're wearing RGPs?

Is rubbing them every day really that bad...?
