Thank you so much for sharing the build with us. I was in the market for used oxygen concentrators but this one device puts out three times the amount of one of the medical devices.
Nice demonstration. I think I will build one myself, soon! ;) DIN is short for German Institute for Standards. Sometimes (wrongly) used as German Industry Standards.
yes trying to learn how to build and thought you guys had a supplier to suggest so we can build this high output machine, especially the Zenolite granules which are costly!
Wait a darned minute 9.97 for a three dollar brass elbow and $140 for simple adapters? crazy pricing and where is the one key ingredient the zeolite absorbent that makes it all work? I dont see a complete kit package and few views and following. Just learning here and Im seeing incredible detail here and yet the overview is missing. 15 LPM at 98 % is awesome but what about humidity filtering and renewal times for the absorbent compound that makes it all work, for a while until it becomes saturated..
Can 12v valves and fan be used? Of course that requires some changes to wiring and higher wattage power supply. Question is though, will the unit function with lower voltage valves? Or, is there a particular reason for the 110V valves? Thanks!
Blood Oxy sensors are basically the same thing they clip on your finger for a few seconds when you see your doctor. Pretty sure its a light(Ive only seen red or green for blood oxys ;probably illuminates blood better[research says two are used]) transistor wired to a microcontroller programmed to read differences in oxygen levels based on the colors that it "sees". Transmissive pulse oximetry is what its called.
@@buildthis2324 I have a general understanding of the tech, I am trying to find the plans they have for actually achieving this. They describe it as an IOT device with blood O2 sensitivity but don't actual describe any way to do this.
@@briancook8077 You might check the GitHub page under OxiKit and I think the answer is with an Espressif ESP32 control board for using Bluetooth. That is just a guess because they uploaded some code for the ESP32.
Hi.. Thanks for your wonderful tutorial and detailed explanation. I have used the code to load the Audrino .. this is version 2 I guess. First 3 relays are working fine but 4th relay which is supposed to run the fan is not operating. Can you please clear this problem? What could be wrong?
I am not sure why did they even put the fan control in the code, that fan is basically cooling the heat exchanger and can be left permanently "ON" for continuous cooling as long as the system runs. Rest you can ask the maker further if that is something that really matters.
