or
- Uses synchronous rectification technology, has high conversion efficiency and stable performance; The input should be at least 3V higher than output.
- With potentiometer on the bottom, which allows you adjust the accuracy with the mini screw, but ensures you won't easily change its setting when mounted.
- Fully sealed, outer enclosure acts as a heat sink, specially made to be waterproof, anti-shock, anti-humidity and dust-proof, more durable.
- With reversed-connection protection, over-current protection, over-heating protection and over-voltage protection, hence is safe to use.
- Perfect for electronic hobby project, wide application, you can use it on radio, Car Audio, LED display, motor, cell phone, etc.

Hi,
I looked into this for a while and came up with a solution I think is pretty good.
I bought this antenna. It can be removed from it's mount so you don't have an antenna constantly sitting on your dash. I then run a 10 ft usb extension cable through the floor of my van back to a raspberry pi I have hard wired into my distribution panel using one of these. The pi has another cheap 150mbps dongle connected which I use to talk with all my devices. Basically I shell into the pi, connect to an open wifi source, then the pi acts as a router/repeater which all my devices connect to. The antenna works just fine on it's own if you only want to connect one device, but my bf and I both like to be able to work from our respective computers.
Hope that helps.
EDIT: for added fun write a little shell script that tries commonly used passwords on locked connections :)
Wrong sub... but, why not use something designed to do this?
True. I honestly don't know much. The only build ive done has used pwm fans.
If you have resistors lying around you can use a voltage divider circuit. This is basicly two resistors that drop the voltage. Watch this in 2x speed.
You could also buy a linear regulator for cheap but these arent very efficient. Link
The most efficent way to do it would be to buy a buck converter. Something like this.

I just found this on Amazon. Would putting this between the panel and the devices help? Or should I just throw away the dream of powering these devices for cheap and save up for a battery and charge controller?
