rebuild old cpap
I have a couple of very old Respironic Legacy cpap machines that do nothing but monitor time used on the machines. I was just thinking, would it be possible to remove the original controller and using an Uno mega controller with sd card reader/writer remake the device into something usable in todays world.
I know there or engineers on this board.
Not sure what to look for in sensors for such a controller but sound like might be do able. Daughters boyfriend has health issues and has never had or can afford a sleep study.
Thinking that pressure sensors must be in the units for device to work, just data not being recorded. Uno can provide signals to run motor. Respironics works off of 12vdc and would be nice to have BiPap machine capabilities out of some old equipment.
Am I off my rocker?

Might be better to look for a newer machine on Craigslist. More features, more control.
Note: I'm an epidemiologist, not a medical provider.

Sounds perfect for Sheldon, Raj, Howard and Leonard.

The one detail you left off your post is "why"? I've seen you rip code and do some pretty amazing things already, so I don't doubt you can, but can't imagine a good reason for doing this. Now, I have taken old CPAP hose and and a fan to to distribute cold air in a kegerator to the tap...now that's an important project, and has provided cold taps to keep beer from foaming. I will support your crazy project, but it needs to fulfill some frivolous or entertaining purpose.

My personal feeling is that it would be more appropriate to just use the machine as a backup once the boyfriend has an Apap and has figured out his best 95%. It is his health that is at issue.
