Knock off nunchucks and an import ESC
EDIT - I pretty much talked myself into the nunchucks and will report back someday about how they work. I am a bit more concerned about the ESC as it has the potential to cause a lot of damage if it fails.
Anyone used any of the knock offs?
OTC locally, the "real" nunchucks are around $20 and the knock offs are around $10. On eBay, I find ones like this which is $4 delivered! And here is a really odd twist - ordering from Asia is about the only way to retain any kind of warranty if you crack the case or cut the wires (I may do both). My experience has been that when you order something that is under $10 from the HK and China sellers who have a good rating, they just send another when there is a problem. If I buy local, crack it open (inspired by this) and get nothing on I2C, I will be stuck with it. But I would not want to get one (actually probably 2) unless it seems likely I will have no trouble. We have a Wii, so I would actually go a couple of rounds with one of the kids to test before opening one. An accellerometer, joystick and buttons all mounted and communicating for $4 delivered from overseas? That is just insane...
EDIT - Speaking of insane, another item I am thinking about is this brushed motor ESC. $4 + less than $4 shipping? If I didn't even use it to control a motor, the 5v regulated by its BEC would be useful in a lot of projects. A word of warning though - this was designed for a plane and significant airflow for cooling is expected. People cut them open and use heat transferring adhesive to attach cooling fins to the FETs with success, but if you sealed this up without cooling it could burn.
