For example. My fridge is starting to have some issues. It wants to keep freezing everything in the fridge. It dials the temperature setting all the way up and we don’t know why. I’ve taken the fridge apart as best as I can the last time we defrosted it just to wiggle all the wiring connections.
I wanted to really see what was going on with the fridge. I grabbed a Raspberry Pi Zero W and a couple of 1 wire digital thermometers and put together a Fridge monitoring system in a couple of hours. I can now see what happens with my fridge. It does a defrost sequence and comes out of it cold, freezing up the fridge.
A quick dashboard configuration, and I now have a view of the current temperature and a graph of the temperature history.
Add a couple of more nodes and I now get email notifications when the fridge is too cold. Another node, and the Google Home announces the too-cold temperature.
My fridge now complains that it is cold.
How epic is that? Under $20 worth of parts to give my fridge a voice.
Over the last few weeks, my front door has gotten a little blue.
I think it turned out pretty good. My wife picked out the color, I just applied the paint. I don't think she realized that I am going to get some white letters for above the door and label the door "Police call box".
Having seen all the kids and junk I've crammed inside, it is indeed bigger on the inside than it would appear.
I bought a bundle of fifteen 1x2s for $12. There are some pretty twisted, gnarly looking boards in the bundle. My dad taught me how to selectively cut with the twists and kinks in mind so the project turns out in the end. I've only 1 wonky spot I am not happy about. I used 3/4 of the bundle of wood with only a dozen of so 6 inch scraps left over.
It's built with tools my wife has gotten me over the last couple of birthdays. I love tools.
