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?December 16, 2020 at 11:12 pm #9281
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!December 16, 2020 at 11:12 pm #9282
[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.December 16, 2020 at 11:12 pm #9283
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)?December 16, 2020 at 11:12 pm #9284
Not to my knowledge, Brent. Do you think there is potential for a similar DIY approach here?December 16, 2020 at 11:12 pm #9285
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.December 16, 2020 at 11:12 pm #9286
Interesting … know any suppliers willing to sell the silicone test tubes in quantities of less than 1000?December 16, 2020 at 11:12 pm #9287
It would be interesting to find out how they manage to push the electronics into the silicone nipple.December 16, 2020 at 11:12 pm #9288
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.
