Update: Contactless Device to stop nighttime dry mouth (build log)
Hi guys,
last time i shared the first 3d printed version of a device I built to help a close friend with dry mouth during radiation treatment.
the feedback and all of your comments made me very happy so i promised an update and here it is.
I went to china to source components and trying to move away from a 3d printed iteration. met some cool redditors who reached out after my last post but i have not yet decided to sign any commitments just yet.
how i adressed everyones main concern (hygiene): i switched from 3d printing to aluminum, switched to a borosilicate water reservoir and decided to rework the PCB to keep pumping the water in a circle in order to not leave any zones that the uv-c can‘t reach.
difficulties i faced are mainly the PCB at the moment, to get the pressure of the pump right and make everything steplessly adjustable AND i wasn‘t aware that there’s golden week in china so unfortunately i am not able to keep building here now so everything will take some more time but stay with me please.
i know it‘s not the update i wanted to share but i still wanted to show the progress and ask for your input again and of course if anyone wants to join my journey you‘re more than welcome.
Thanks everyone for your time let me know if you like the new design
