  • I fear there is no such system where this applies. The tech stack on any old netbook is so advanced and complex that there is nobody on this planet who fully understands it.

    Being theoretically able to read the code is certainly better than not being able to, but it’s not the same as having actually read and understood all the relevant code to the point where you can be somewhat confident that there’s no backdoor in it.

    (And even if someone had the time and mental capacity to do that, at some point when going through the stack you always hit a proprietary layer. Be that drivers, the bootloader, component firmware or the hardware itself.)













  • It’s called PEPit, and it can be found here: https://github.com/Dakkaron/PEPit

    Most of the documentation is in German, since my primary audience so far were people living close enough that I can hand them devices and I haven’t gotten around to translating everything to English. But I think it should be simple enough that auto-translation should be understandable.

    I’m not sure what to do about distribution other than just handing them out for free, having them sign waivers, and getting funding from a charity or similar organization.

    That’s what I have been doing so far. I “sold” a few of them for the price of the parts. I donated two to two different local hospitals to use with in-patients. I got a physiotherapy device company to donate money for a scientific study at one of the hospitals, where they will hand 30 devices to patients to keep them and measure how it improves their therapy experience. But so far that’s pretty much the end of the road.

    I’m already worrying about how I can even do the study without getting in trouble in regards to taxes and stuff.

    It would be really cool if someone else would start picking these up and making some for kids that need it.

    This is mainly made for kids with Cystic Fibrosis (like my kid, who was my original audience for the device), but I talked to a few people with broader experience in regards to lung conditions, and it would also work well for kids with Asthma (for RMT therapy) or people with COPD (for inhalation and PEP/RMT therapy). PEP is breathing out against resistance, RMT is breathing in against resistance.




  • Tbh, no. The device is realistically priced for a niche medical device with low number of units sold. Medical certification alone is around €500k. Development costs for a very custom device like this are also quite high. The price point isn’t crazy at all.

    At the same time, health insurances (even more so here in Europe than in the US) are pretty slow to pay for new technology, especially if the benefit isn’t immediately tangible.

    As in, “Will this reduce the need for further insurance spending by e.g. preventing hospital visits?” or “Will this allow a person who is on disability benefits to return to work?”
