My apologies, all.
If building a diy ventilator helps you cope with this hideous situation, by all means do so.
It beats the hell out of doing nothing.
The US Gummint tried to do something similar. https://www.nytimes.com/2020/03/29/business/coronavirus-us-ventilator-shortage.html

They failed but not for practical reasons.

But do be careful out there.
