Hi,
Hope you are doing fine!
In this verge of oxygen deficiency the country is facing ,a project like this is very much needed,I am an electronics hobbyist and ,I have been trying to develop my own concentrator using electrolysis of water ,I have no idea about its concentration,but I sure can research on the topic,rest of the electronics are simple circuitary which can be managed within a day,The challenge is the concentrator, Provided time I may be able to make it happen, In reality oxygen concentrator costs much due to the use of super costly materials for higher purity of oxygen,This cheaper alternative may/maynot work, (THE PRICE CAN BE BOUGHT SERIOUSLY DOWN IF YOU ARE PLANNING TO MAKE A MINI OXYGEN CONCENTRATOR like a bottle of oygen)?
If you are interested in working with me lets meet on chat
Yours Sincerely,
Suryasaradhi
