Sorry to add to topic glut, but this seems something people would be interested in. It's briefly come up in the Nintendo conference thread, so I guess many skimming or avoiding that thread could miss it... maybe we even missed earlier discussion of the same fact. Anyway, BorkBork posted
I hadn't seen that. Interesting. The Wii Remote and Nunchuk attachment use an ADXL330 iMEMs accelerometer. Search for ADXL330 and there are quite a number of results.
This seems to be the main product site. It looks like on that page they can be purchased in bulk (1000-4999) for $5.45 apiece.
Has anyone noticed any press releases about the sensor bar?
To which I replied:Err is this document old?

Details about the controller.

Here's an article from late last year about the ADXL330. Here are the bits most interesting to us:The ADXL330 is a small, low power (200µA at 2V) 3-axis iMEMS® accelerometer complete with signal conditioned voltage outputs on a single monolithic IC. The product measures acceleration with a minimum full-scale range of ±3g. For tilt sensing applications it measures the static acceleration of gravity. It also measures dynamic acceleration resulting from motion, shock, or vibration. The ADXL330 is available in a small 4 mm × 4 mm × 1.45 mm, 16-lead, plastic LFCSP.

# Handsets
# Motion-Enabled Gaming Devices
# Disk Drive Protection Systems
# Sports and Health Devices
"This is the first three-axis motion sensor accelerometer and the first single-chip three-axis MEMS accelerometer with signal conditioning and circuitry together on the same chip," said Mack Lund, the company's product marketing manager for micromachined products. The chip's mechanical sensing structures allow it to offer low power in a small package while also providing stable performance over its temperature range, he said.
In addition, the device's low supply voltage, from 2.0 to 3.6V, benefits battery-powered applications, Lund said. "If users only need to use this for short periods of time or they want to duty-cycle it, they can get even lower power than best-in-class," he said. The device can turn on in 1 msec, take a measurement, and turn off again to save power, he said.

The ADXL330 is now sampling and costs less than $2 in high volume, according to the company. It is slated for volume production during the first quarter of next year.
