My project this winter break is to get our Wii copy of LEGO Rock Band some controllers again. We sold the original ones years ago because they were gigantic, so any replacements need to be small and easily stored.

right now, it requires some kind of binary desktop app to configure the firmware,

## Drum controller
The first decision to make was ## Step 3: Drum controller
finger drumming vs hitting things
with sticks: we decided sticks
would be more fun.
The second decision was There are a lot of options that could work as a drum controller,
MIDI vs destructive conversion. including "finger drums" like the Akai MPD218,
Conversion looked cheaper and easier, full drum kits like the Alesis Nitro Mesh,
so we went that way. drum pads like the Alesis SamplePad,
or options to build my own kit with piezos.
A few factors went into the decision:
1. We wanted something you hit with sticks.
Hitting things with sticks requires big movements,
which will result in funnier situations during the game.
2. We wanted something that was easy to hook up.
The devices with MIDI output would require at least a translation device,
the USB MIDI devices would need the translation device to plug into power.
If possible, we want the "rock bands drums" to just plug in to the hub,
and that's all.
3. Since nobody's built anything like this before,
we wanted to start cheap.
