Re: Homebuilt '12V Camping Converter PSU' for Resmed Airsense 10

TheSnoringMan- I should have written this reply a long time ago. Just wanted to say Thanks for all your information and replies about the converter. I have followed your plan and built it using a old laptop brick cable. It is working fine. I did put a scope on the resistor and saw the 'sweep' you ta...

D.H. Is that a DC -> DC converter you saw on amazon? Or maybe just the AC brick? I've seen those for about that price. TheSnoringMan Hmmm, a 'sweep'. I can understand a voltage sense with no load and then a voltage sense with cpap load. But as 'sweep', something like tracking a curve (an A/D and all...

Re: Homebuilt '12V Converter' for Resmed Airsense 10

TheSnoringMan, thanks for your posting of the 12V converter. I was thinking about playing with a converter design also. Could you do me a favor and measure the voltage drop across the 2.7K resistor when attach to the cpap? If I come up with another working design, I'll let you know. P.S. Laughed out...
