Re: Powering a 10V-36V amp with the GPIO

You could use the Pi to drive a relay (or use the pi to drive a transistor to drive the relay, not sure if the pi can provide enough current for most relays) which could control another power supply for the amp. You could still have that power supply inside whatever your pi is in, so you'd only have...

Re: Running RPi Headless using wifi?

If you set up the wifi so it automatically connects (I can't remember it's name, but I used the GUI programme included now with raspbian, run startx and it'll be on the desktop) then you can happily connect to it so long as you know it's IP. I couldn't be bothered to fight with working out how to se...

Re: Controlling RBPi from windows PC

Java or Python (or anything else platform independent) and sockets would do what you want fairly easily. Simple client-server socket, write your own protocol and then make your server side of the application do whatever you want.

For most boards this is true. But not for all.
Then surely that's a faulty board and should be returned and replaced?

Re: What is the aim of this project and it is really open ?

Will there be a WiFi option? Not in the first version, though you can add a dongle. ARM Linux WiFi support can be a bit patchy; there’s a list of tested dongles on the wiki. => one need a powered hub on rev 1 most likely, unless one modifies the board and loses its warranty. Small point here - quit...

Re: Wii Homebrew + Raspberry Pi

Pretty sure the Wii uses a PowerPC. I doubt all the libraries required to run a Wii application (not know anything about Wii homebrew) would be easy to make available on Linux anyway.

I don't think the Pi is anywhere near fast enough to run an emulator of the Wii.

Could you not just set only the Pi to use OpenDNS's servers? Rest of network would be unaffected.

Can you also point out the bad practice of setting all RPi using a distribution to a single dns server.

Re: JavaScript and GERT API

Javascript is purely client side, you'd need to use something like AJAX or more simple POST requests to the pi running something (ASP would do), which could then interface with the board.
