Just saw that there's a similar (commercial) device: This doesn't connect as an extension to the Wiimote but directly to the Wii via USB. Seems to simulate the Rock Band drums. Interesting approach, too, especially as the Rock Band drums support cymbals and velocity sensing. Cannot be used for playing GHWT though...by drayde - Hardware
Check out this page: It's a library for implementing the Wiimote<->extension protocol using AVR microcontrollers. On the bottom of the page you find information on how the encryption works. I plan to use the library for making a DIY extension that allows you to connect a MIDI drum it and pretends to be a Guitar Hero World Tour drums controller. See this threadby drayde - Hardware
Oh yes, I found something very useful. This guy build a drum controller that connects to the Wii remote: As it comes with source code it shouldn't be too hard to modify it to a MIDI drum controller. Awesome!by drayde - Hardware
Thanks DrLucky for your input. This guy has a project called X2Wii, which converts signal from a N64/Snes/Nes controller for using with the Wii. I first thought it contains things useful for my project idea, but it turns out that it emulates a Gamecube controller to be used with the Wii. Unfortunately this is not helpful...by drayde - Hardware
Hi all! There is this idea in my head: Wouldn't it be possible (and not too hard) to create some some piece of electronics that takes MIDI commands from a E-drum kit and convert that so it emulates a Guitar Hero World Tour drum kit? In other words it would allow you to use a proper MIDI drum kit to use for Guitar Hero or Rock Band. If I am not mistaken, the GT WT drum kit is a extensby drayde - Hardware
