(Referencing the recently demonstrated $300 build): $300 Food Computer
In response to the questions:
(1) I am mirroring the project exactly except for a wooden frame.
(2) Some familiarity with python, first time working with Pi/arduino/sensor type tech stuff. Have soldered larger wires before.
(3) The si7021 is failing when I run the test script as well as the validation UI script.
Test script reads:
Failure to get temperature, no sensor found; check pins and sensor
2017-08-30 03:40:54, si7921-top, Failure, temperature, ,Sensor not found
“comment”: “Sensor not found”,
“timestamp”: “2017-08-30 03:40:54”,
Test si7021 reads:
Test SI7021 Sensor
Traceback (most recent call last):

Below are pics of my poor soldering skills (could this be the issue?), and the wiring back to the Pi. Will take better pictures tomorrow if it helps, my apologies. I also noticed now that you all built this in St. Louis, which happens to be where I’m from as well, small world!
