Progress has been slow on revision 2 of the TOS Tricorder. I have been working on the software, particularly the plugins for the sensors. I am currently working on the I2C sensors. I have 2 of the 8 sensors coded but found an issue with detecting the I2C devices in the init method without getting the I2C bus into a stuck state. I finally figured out this issue this morning and updated the Raspberry Pi forum post were I found the original code that I used. If you are interested, you may check out the post at https://www.raspberrypi.org/forums/viewtopic.php?f=32&t=114401.
Another quick note, I found the lambda function in Python. I may put this to some good use. I had to do something similar but found a way around it as I never stumbled on this gem. In many ways, I wish I stuck to C++ for this project but it is good to get to know yet another language.
