This year we received a gift of some battery powered ceramic Christmas tree decorations. (I’m not sure if this is the exact model, but it’s very similar.) They have a built-in timer that turns them on for 8 hours and then off for 16 hours. It’s very rudimentary, but it worked… for a few days. Each tree takes 3 AAA’s and we’d have to swap them out every few days.
After the Christmas season, I decided to convert them to plug power. I’ve done this type of thing before, but I’m not super confident in my abilities yet so I decided to purchase some parts to make life a little simpler instead of doing it from random scraps around the house. I bought a 4.5V power supply with three barrel plugs coming out if it and everything had white cords. I also bought power jacks that were the same size as the plugs and came with wires already connected.
From that point, I was able to figure out exactly where to connect the new wires. I did this with the continuity tester on my multimeter. This helped me figure out what was the start and end of the battery tray. I plugged in the power supply, connected to one of the jacks, touched the wires to the correct battery terminals and voila! Light! From there, soldering the wires onto the terminals wasn’t too difficult.
The trick was that without major surgery to the trees (or using a different connection), I wasn’t able to fit the jack into the footprint of the tree. And since the trees spend the rest of the year in styrofoam holders, I couldn’t modify the size of the tree. So the plan was to have those wires and jacks soldered in place but then the base would be removable.
I turned to Fusion 360 and modeled a base that is about 3/4″ tall and has a lip that surrounds the base of the tree. There’s a cutout in the bottom to feed the wires out to a hole for the jack. Since Fusion 360 is parametric, I was able to just adjust some parameters for each of the three trees and print out three different sizes. That worked but my initial design was a pure cone shape. It looked a little awkward, so I made the edges of the bottom wavy like snow and that improved things dramatically.
Thankfully the trees still work after this adventure and I’m excited to set them up next year. They will get plugged into the same setup and go on/off with the timer that controls the rest of the village. No more batteries to swap!
















Peak Craft Beer?
I rarely mention “drinking beer” as one of my hobbies, but I thoroughly enjoy trying new beers. My Untappd app tells me I’ve had well over 1500 unique beers. The Pacific Northwest is one of the best places in the world for craft beer, but lately, I’ve felt like maybe the fervor is dying down a bit.
I thought maybe some of it was just that my favorite brewery, Good Brewing Co, has effectively closed. The Sultan location still exists, but as far as I know, it was sold to new owners and no longer brews any of its own beer. Bummer!
But it’s more than just Good Brewing. When I visit Total Wine, the enormous selection of craft beer packs and singles has been reduced to a glimmer of its former glory. At Safeway, the craft beer section has been mostly replaced by cider and even more beer from the big/national breweries.
Expanding the scope, the picture doesn’t get better. Craft beer declined in 5% after a 4% decline in 2024. More breweries closed (434) than opened (268).
Craft beer isn’t dead, but it’s not expanding like it was before. Get out there and support your local brewery!
