    The winners of the 2020 Hackaday Prize were announced a little while back – the winner was the BYTE – a hands free pointing device interface controlled by the mouth.

    The design uses a silicone adult pacifier nipple to cover the sensor, and a flat ethernet cable to connect to the USB interface.

    A single build is approximately $141, but it can be produced at quantity for closer to $20.

    Is this something that would be useful to you or someone you know?

    That’s really cool!

    The design uses adult-sized pacifier nipple to enclose the electronics which is brilliant! I think these (nipples) may be used with many other hands-free controllers.

    THANKS for sharing!

    [Silicone test tubes](https://www.graylinemedical.com/products/sarstedt-test-tube-silicone-45ml-12x75mm-non-sterile-1000-ca62557015) could be another option if you need something longer than the pacifier. Silicone pipette bulbs are shorter but come in different shapes.

    Does MMC have any contact with university researchers working on [soft geometric dielectric elastomer switches for soft robotics](https://www.spiedigitallibrary.org/conference-proceedings-of-spie/10966/109661M/Soft-geometric-dielectric-elastomer-switches-for-soft-robotics-Conference-Presentation/10.1117/12.2515213.short)?

    Not to my knowledge, Brent. Do you think there is potential for a similar DIY approach here?

    The King Actuator build process appears to be reasonably DIY friendly. https://softroboticstoolkit.com/king-actuator By embedding electrical components before casting, someone could potentially use the King process for a switch instead of an actuator. The challenge would be protecting the electrical components from the solvent used to dissolve the inserts.

    Dale at Maker Works designed and built a CNC hot wire cutter for making intricately shaped foam pinewood derby cars. It could easily cut the foam inserts.

    Interesting … know any suppliers willing to sell the silicone test tubes in quantities of less than 1000?

    It would be interesting to find out how they manage to push the electronics into the silicone nipple.

    This is described somewhere, but I can’t remember where. Either on Hackaday or perhaps on one of the video linked from there. As I recall, they use a tool that is inserted into the nipple and then pried open to stretch the silicon enough to insert the electronics.
