I've begun experimenting with a nebulizer as a breathing apparatus. I think it might just work. I'll power it with a 12v battery hooked to a converter, then to the nebulizer.
I’ve built basically the same system using an aquarium compressor powered with a 7.5amph motorcycle battery, works fine for shallow diving, under $150.00
No joke, you need help, if you think so little of your life. PM me. I would give the info for you to put me on your life insurance policy as a beneficiary
