Folks, I tried out the RS-232 9 pin connector. It is leaky as hell. Try this (at home). Take a 9 pin connector and suck at it. If you can feel the air rush into your mouth, you know it leaky. Get to

Well, good to have a group for this. - Today I've been testing the ic drivers, since I have some parts them at the office and I had some spare time. I'm attaching the schematic I've been using. I had

From my experiences in building cave radios most connectors leak like this. The idea to pass the wiring through a hole ( with grommet) and seal sounds like the most effective low cost option. Regards

I was referred to this by KP, the anesthesist. https://interestingengineering.com/watch-this-3d-printed-adaptor-transform-snorkeling-mask-into-ventilator

thanks for running those tests!? good information!! gordon

Draft of layout with connectors Bob? KD8CGH

I mentioned using an Ardunio shield to drive the valve. One class of these boards uses the L293D driver chip, which is rated at 600 ma per a channel on the 4 channel device, with a maximum voltage of

Dear friends Yes most commercial connectors will leak. I have designed several medical /products for defence. I could help Please let me know how many pin connector do you need? Also trying to seal it

I'm working on the three passive valves (Anti-Asphyxia, Over-Pressure, PEEP). The approach is to 3D print parts that are attached to 1" PVS pipe Ts. I think that the pressure sensor should also be

I suggest that the pressure sensor be mounted in a 1" PVC T with a threaded leg using a threaded cap. The sensor can be mounted in the cap and wires brought out through a hole easily drilled in the

Ashar -- what about gluing a connector to the top of the sensor chip?? ?Then we coud just use a thin tube to go to the airway circuit, which is the NORM in anesthesia and intensitve unit care.?

That will be useful for people who merely need increased oxygen concentration due to SHUNT in their lungs induced by the pneumonia. But there are much easier ways to do it that are routinely used in

thanks, great idea!

thanks!? ?I think I saw someone testing this type shield here somewhere. Gordon

These are such good ideas tht i contacted the mechanical engineer in the University of Florida group, DAVE LIZDAS and recommended that he join here to see what is being done.? ?The two of you think
