This logger uses a micro SD card to read parameters and log details. It automatically creates a new folder with the values as soon as the power is connected.
We found out that motor rpm disturbs the readout of the sensor values and designed a software that takes an average value. This works.
In our setup we use the following parts:
Parts from:
www.sparkfun.comLogomatic V2 micro SD card logger. Power parallel to ESC. XYZ to port 123, UI on port 7-8. Next to port 7 and 8 there is a ground connection; this allows you to solder a servo lead connector directly to the logger.
AttoPilot sensor board for measuring voltage and current. This allows you to calculate power and consumption. This board is soldered directly to the ESC input wires. The leads are put through the PCB directly into the male and female 4mm connector.
www.pololu.comMMA7260QT XYZ-axis accelerometer, glued with double sided tape to the back of the logger.
The pdf gives all the details of the software modification made.
The picture shows my sensor timer, the logger with the sensor taped to the back and the attopilot shunt in the feed line of the speedcontroller.
