Hello,
I have been thinking about this lately and with readily available Arduino board and three-axis accelerometer boards I would think that It would be possible to get this done for around $30-$40.
What I am interested in is a unit that would only record the three-axis accelerometer data, no deployment or anything else, just recording. I have seen you tube videos where they connect
the ADXL345 three-axis accelerometer (or 9 df IMU etc.) to an Arduino board. However, I would need a stand alone memory chip to record data and the software (e.g. after turned on it
won't start record until 2G for at least 0.5 seconds or something like that when rocket is on pad). I also think the Arduino board can be stripped to only keep the necessary components like
the main chip and some interfaces (USB port) etc. All powered by a 2S Lipo or so. Any ideas and thoughts are appreciated.
I think there was an article in Sport Rocketry some time ago about some similar unit.
