Final Assembly today
We started with the installation of the Plexiglas sides, zip tying them to the PVC frame and along the back to the Reflextix. Cutting holes in the Plexiglas was super-fast, and using a heavy duty 3 hole punch. No problems with cracking the Pexiglas and when the protective sheeting was removed, the sides are nicely transparent, providing viewing of the internal working of the Food Computer
The rest of the components went together quite smoothly. We’re going to wait on our final taping of the side, top and bottom edges to be sure that everything is working correctly.
Two issues we discussed as we finished construction:
- We should have placed the bottom layer of Reflectix inside the bottom plywood to prevent the wood getting wet. We’ll use a tray or some of the extra Reflectix to cover the bottom if needed.
- Due to our environment, we expect that we will want to create some sort of cover for the electronic components on the top of the Food Computer to protect it from both dust and wandering hands of some of our patrons. We talked about using shoe boxes with ventilation slots cut in the ends (at least temporarily.) If these seem to work, we can get some similarly sized plastic boxes and cut slots in those.
Hooked up and restarted the Pi, but no temp or humidity data is registering. Going to have a radio guy take a look at our solder on the sensor to check it’s solidity.
Also noted that the date is wrong, so will investigate how to reset that too.
Radio guy resoldered the pins to the sensor. This didn’t correct the sensor data issue. Is there another way to test the sensor (or camera) input? At this point i’m not sure we’re getting any input from these devices at all.
Date and Time continue to be incorrect, despite resetting them several times.
Tried installing the ntpdate program suggested here: https://atinkerersblog.wordpress.com/2014/01/15/updating-the-system-time-on-a-raspberry-pi/
but got a permissions error and was hesitant to do anything more.
Further reading indicates it may be a problem with our wifi network: https://www.raspberrypi.org/forums/viewtopic.php?t=13313
