Tonight's the night!
Alrighty then. Wicked bad storms supposed to be coming through. Dog is doped up with Zanex. I am about ready to go to bed. With the storms out there, I decided to go ahead and press the homemade DC CPAP UPS into service. This is not your Best Buy or Newegg UPS. I assembled it from a small radio power supply I cranked up to 14.5 V, a Super PowerGate from West Mountain Radio and a 12 V 35 AH battery. I have some fine tuning yet to do on cables (YAY! More stripping and Power Pole crimping! So much fun!), but it is functional in current state.
Not that I expect a big outage, but with storms, particularly big thunderstorms as we see in North Texas, often the power blinks for a minute or two. Usually just long enough for me to wake up real good (I roll over waking about 3 seconds after the CPAP goes dead - at that 60 second mark I am usually WIDE awake). Sometimes it lasts for 5-10 minutes before power comes back. Sometimes once it goes out and comes back up, but it will go out again one or two more times. I am thinking this usually has something to do with a transformer somewhere in the area getting popped or maybe even a structure at a local substation, followed by a kind of reset. But what do I know? My electrical engineering education consisted of spending the night at a Holiday Inn Express while traveling on business a few years back.
I intend for this to be a full time setup once I do some housekeeping an the aforementioned fine tuning to the cable configuration. Will hit ya back up afterwards.
