Can I use this power supply in my car?
Hi, I'm new to this stuff and I have a question. I have a little budget project here so I'm trying to use parts I have laying around :-)
I've got a "NEXTerminal" with a DC-DC power supply. The input voltage is said to be 12v, but I do not know how tolerant it is to lower or higher voltages.
I have figured out a way to keep the voltage from dropping to low - I'll connect a small motorcycle battery to my main one with a diode, and run the PSU from the smaller one. that way it will keep the CarPC power from dropping too low during cranking, and the small battery won't be able to power the accessories in my car. However, during normal alternator operation the voltage in my car gets as high as 14.5 volts, can I let my psu run off this without any adverse effects?
Also, perhaps someone has a good way to convert a signal from an analog push switch to a keyboard command without an expensive emulator?
