    GP2X Leading By Inappropriate Examples?

    Sorry, not sure what you mean by that? It's likely it will tolerate at least 5V, but be careful because there are some devices that wont. I'm more worried that there may be other things inside the GP2X that are not connected through the DC-DC converter, so they would see the actual input voltage.

    GP2X Leading By Inappropriate Examples?

    Normally it would just waste heat and melt your GP2X! :lol: But the device I linked to is a switching regulator (aka a DC-DC converter) which draws a given power to match it's output power. By upping the voltage supplied to it (up to 40V in the case of that particular one) you can reduce the...

    GP2X Leading By Inappropriate Examples?

    Yeah, I know what you wanted to do. :D I think everyone's tried it at some time. It will work. You can stick two batteries of more or less equal charge state together and they will power the device. It wont last twice as long though, and if you keep doing it one of the batteries will...

    Issue With Batteries...

    Any contamination of the battery connectors will result in degraded performance at the sort of current drain the GP2X has. You should make a point of keeping it all very clean and ensure strong springy contacts. - Avoid touching the metal parts of the battery or battery contacts when changing...

    Sandisk Ultra Ii Sd Cards - Which Are Ok To Use?

    Do you have a pointer to a list of which card readers have that chipset?

    GP2X Leading By Inappropriate Examples?

    You don't! You may damage your batteries. At best, you could use some ballast resistors or diodes, but this will be wasteful and still poor practise. Since Squidge points out that there's a constant-power regulator (DC-DC switching converter), the best solution here is more volts. That means...

    GP2X Leading By Inappropriate Examples?

    Hm, perhaps you have answered my original points indirectly here! I'm no Linux or ARM guru, but from those three statements, it seems possible that the CPU is using around 90mA, and any savings from idle-waiting etc. will be unlikely to create any greater benefit. Two cores at 90mA, 40mA...

    GP2X Leading By Inappropriate Examples?

    It's a shame the buttons didn't get an interrupt considering the target applications here, but as you state, a periodic poll is probably acceptable since the code would likely be doing other things at a fairly high rate that the button would be pressed in response to. On a 200MHz processor...

    GP2X Leading By Inappropriate Examples?

    That's the actual SDL code? Bit of a downer. :angry: Although it is doing a Delay() (which may or may not idle to CPU - it technically could/should) and will therefore reduce battery consumption, it is unfortunately going to mean WaitEvent() doesn't return immediately an event happens. By...

    Sandisk Ultra Ii Sd Cards - Which Are Ok To Use?

    Does anybody know if the GP2X can take advantage of the 66X, 133X, 150X etc. cards extra speed? There's only a point in buying a fast one if a bog-standard one performs worse. The 2GB Sandisk Extreme III seems a popular choice online right now. (AKA many places haven't got stock! :lol: )

    GP2X Leading By Inappropriate Examples?

    Well it's usually a bad idea for your first forum post to be contentious, but I'm going to anyway! :P I hope people will take this seriously and discuss the subject in the constructive manner intended. :ph34r: For some time I've been following the GP2X scene and am on the verge of buying...
