  • Hillarity. Thank you for that, sir.

  • You can replace the motor on a peristaltic pump of this design, but the motor needs to turn continuously- so you’d need a stepper motor and not a servo. Second, to be able to pull liquid at all, the pump (dependent on the design) needs to keep a high RPM to sustain a vacuum in order to pull liquid at all, and to eliminate bubbles in the airway. This design:


    Watch the video, and think about replacing the human finger with a servo, stepper or solenoid. If you’re interested in that pump design, please comment back as I have the means to fabricate them for you (super, super inexpensive).

  • Dan- I’ve done research regarding brain-mapping kinematics (interpreting desired body movement through an EEG) working towards developing prosthesis controlled by thought. If you’re interested what I have to share, feel free to pm me at any time. With respect to fabrication, I have a commercial grade 3D printer as well as a CNC machine shop- both of which are at your disposal.

    This is not a solicitation and I expect nothing in return from you.

No public wish lists :(
