Punching accelerometers

Shortly after finishing his Makiwara punching bag, [Abieneman] wired and programmed an Arduino to an accelerometer to find out just how much acceleration (and with some math, force) is behind his punches. The project is simple and would be quick to reproduce for your own measuring and experiments: all that he used included an Arduino, accelerometer (with A/D converter), LED displays (and shift register). We were a little disappointed to learn of how much static the accelerometer produced, so measuring things such as impulse, energy, and pretty much anything not kinematic is nullified. But it makes us wonder, how much static would be in say, a Wii Remote punching bag?
