    Micro-update

    Here are some pics of what we're up to in the hackerspace! Currently rebuilding the kit and setting up a test system for these centrifugal pumps, which are magnetically driven and all-polypropylene (no rotating seal). Currently setting up the power electronics to try to do speed/flowrate control/ramping.

        @kirk

        This design of pump connection is very common in the industrial-catering machine-design industry. 😁

        This would be a source of reasonably-priced pumps, that are designed to be maintained.

          That's great! Do you have a link to one or know where we could procure one to test?
