First, a DC-DC converter that raises the voltage is and same thing as using an invertor (DC to AC) and then a rectifier (AC to DC). It just does it all in one package. You can't raise a DC voltage directly. You have to convert it to AC, run it through a tranformer to raise the AC voltage and then convert it back into DC. Whether this will allow or generate noise into the system depends on the converter just the same as some inverters are 'noisier' than others.

Second, if the Gamecube does run on 12V you still maybe should not hook it to the car directly. If the gamecube is rated (should be written near the plug) for a wide voltage range of say 11V to 16V then you should be ok. Otherwise you need to install a regulator to keep a more consistent voltage level the device can deal with. Unlike the DC-DC converter above, a regulator cannot increase voltage it can only keep it from going above a certain level so if your car's voltage ever dips below the voltage regulator setting then the output of the regulator will go down with it. That means you could still possibly "brown-out" the gamecube.

 

Where are you going to place the monitor? I assume your going to mount a touchscreen if you plan on installing a computer?

 

Granted, but there is a big difference between a DC-DC converter (ok, so DC-AC-AC-DC) and converting 12VDC to 240VAC 50HZ (Aus specs) and then back to DC using the original plug pack in two separate units. The inefficiencies and noise are just horrendous not to mention the bulk and wiring. That was my objection to using a mains AC inverter.

 

It's possible. Not sure how many Aus guys would want it though.

 

ok.. so with all this conjecture, what's a brother to do?

i could just modify a joytech in car power adapter?

 

I don't think there is any conjecture just discussion about technicalities.

A decent DC-DC converter is the best option and the P1900 unit is the pick of the bunch for Mac Minis and additional 12V units.

One thing I am interested in though is a 12V gell cell battery back up so fluctuations in voltage don't crash the PC. I note the P1900 has an additional 12V input. I wonder if this is intended for a backup?

 

Far as the gamecube is concerned they make automotive power adaptors that plug right in to the game cube from the power socket in your car.

You could always cut and hardwire this.

 

nice one hahn. just picked one up off ebay for $3.

aus- i think a backup battery is a great idea.. i would love to run the gear direct off the second battery and charge it off the main.

would that impede at all on the main batteries function?
