I just would like to share with you a device that I made. It is a syringe pump. Often during the night, our nose becomes dry, so we can use a humidifier. It works but has its limits. So I have designed this syringe pump in order to inject physiologic serum into the nasal cavities all night. You can set the quantity injected and the time between each injection. Ant that's it.I made a GitHub to share with you all you need to make your one syringe pump (3d parts, links to mechanical and electronic parts, electronic schematic, and code).https://github.com/aurerum/OpenSourceSyringePump

I use it for one month and it helps me to sleep, it is not a huge improvement but it is a welcome one. So, what do you think about this?
