Analog Devices Guess the G’s Contest

Analog Devices has a great little contest to guess the peak G-force of an Estes Big Daddy rocket.  They are using an accelerometer very similar to our ADXL335 breakout.  Pick one up, build the big daddy,  launch, and win yourself an iPad!

We placed our MEMS accelerometer into an Estes Big Daddy rocket and launched it! Here’s where you come in. Guess the peak gravitational force (G-force) on the rocket during liftoff. The person who picks closest to the actual value, without going over, wins an iPad! Fill in the short form, and submit your guess. In case of a tie, the person who submitted their guess first will win. You can only enter once, so give it your best guess!

ADXL335 – 5V ready triple-axis accelerometer (+-3g analog out). We’ve updated our favorite triple-axis accelerometer to now have an on-board 3.3V regulator – making it a perfect choice for interfacing with a 5V microcontroller such as the Arduino. This breakout comes with 3 analog outputs for X, Y and Z axis measurements on a 0.75″x0.75″ breakout board. The ADXL335 is the latest and greatest from Analog Devices, known for their exceptional quality MEMS devices. The VCC takes up to 5V in and regulates it to 3.3V with an output pin. The analog outputs are ratiometric: that means that 0g measurement output is always at half of the 3.3V output (1.65V), -3g is at 0v and 3g is at 3.3V with full scaling in between.
