After I had a poweroutage during a thunderstorm, I decided to see what i could do to make a simple UPS for both my Meteobridge and my Blitzortung-station. I came up with a simple, low-cost solution with a Raspberry Pi extension module: StromPi, produced by JOY-IT. h[url]ttps://www.joy-it.net/strompi/[/url]
I connected a battery holder with 4 1,5 v C-cells to the "wide-range power connection", with accepts everything from 6-36V DC. Connected the power supply to the "IN" USB-B connector, and the Meteobridge to the "OUT" connector. Now when I disconnect the power supply the system keeps running perfectly :D When the powersypply is connected the green LED lights. When the main power is off, and the system runs on battery power the LED turns blue.
Price of the Strom-Pi and battery holder is below € 25,00
I thought I'd share it with you, maybe it is helpful to someone!
