Solar Panel Lighting Kits
How can I power a 5volt WiFi repeater with a 12volt Car Solar Panel?
I want to extend my WiFi so I can sit at my pond and surf the net while fishing, However its around a corner and below a hill. SO I was thinking of having a repeater connected to two cantennas. I have a car 12 volt Solar Panel, it has an LED light that pulses when it sends electricity to the car cigarette lighter. It can be found at harbor frei&ht. I also have some 12 volt batteries that go into backup UPS. Any Ideas how I would hook up the repeater to the batteries, and convert the 12 volts to the needed 5? The repeater would need one amp. I can solder and have a very basic understanding of electronics. I’d love a kit or something. I would put the repeater and the batteries in some sort of container to protect from rain. Anyways, thanks ahead.
I have some old pc power supplies, I wonder if I can strip what I need from them since, they have 3, 5 and 12 volt dc out. hmm.. Thanks
UPDATE: I found a decent instructable that show how. Thanks everyone.
You can buy a voltage regulator that will do what you want with a very simple circuit. Here’s an example:

Sounds like a fun project. Good luck!
