Homemade Air Filtration

Many years ago, I duct taped an air filter to a box fan and hung it from the ceiling above my workshop area in the garage. It’s cheap, but it was so effective that I ended up having another one that I move around the shop when I’m doing a particularly dusty task. (Note that it is a bit of a fire hazard to purposely draw some dust right into your fan motor so use at your own risk. The filter doesn’t catch it all.)

That has worked great for years but it’s a pain when I change the filter because it’s hard to get the old tape off and then the new tape doesn’t want to stick to the dusty fan. After thinking about ways that I could model and 3D print some kind of clip, I realized that others had surely solved the problem before. Sure enough, I found a great model online that included the ability to easily resize the clip to fit my specific fan and filter. After a little trial and error, I got it sized just right and the clips are awesome! This is so much better than the old tape approach. I did have one of the clips break when my mobile version of this fell over so I might reprint these to be a bit thicker.

Doom Scrolling Thoughts

I recognize that this is a loosely supported hot take, but you know how we look back at smoking in the early/mid 1900s and wonder how they could have done that to themselves? In 30 years, I think we might look back at social media like that.

I’ve been chewing on this for a while and it’s one of the main reasons why I stopped using social media in general but more specifically, I avoid any app with an infinite scroll. That mind-numbing flick, flick, flick feels like the exact opposite of what we’re told about how to decrease the risk of cognitive decline (Alzheimer’s, dementia, etc.). Much of the research into those diseases is inconclusive at this point and then I realize it’s another big leap to say that doom scrolling makes it worse. But it seems illogical that repeatedly losing track of time while scrolling through 10 second videos is going to strengthen your cognitive abilities. Smoking one cigarette doesn’t give you lung cancer and flicking through videos on the toilet one time isn’t going to rot your brain, but what does prolonged and repeated infinite scrolling do to you?

This is going to take the scientific community a long time to study, but there are already papers available that link doomscrolling to poor memory, shorter attention spans, impaired decision making, and cognitive overload. In kids, it has been linked to increased rates of anxiety and depression. Links are one thing, but is it correlative or causal? This is harder to figure out but there is evidence for doom scrolling being causal. There are some studies that survey how people feel and perform after being exposed as well as fMRI studies showing craving reactions and abnormal prefrontal cortex activity. There are also strong causal links between doom scrolling and increased stress (cortisol) levels which has major known negative effects on long term health. At the same time, technology can massively improve your mental health when used correctly. There is a difference between passive scrolling and active, intentional use.

“All in moderation” is a motto I support, but after setting up an app on my phone that tracked my screen time, I realized that I’m not able to do infinite scrolling in moderation. I’d rather err on not using it at all.

75,000 Mile Update

Welcome to another Tesla Tuesday!

It has been 8 months since the last post in this series, but that’s certainly a case of “no news is good news.” We continue to love the car and pile on the miles. And, knock on wood, we still have a grand total of 0 service visits. No recalls, no warranty service. Nothing. The only service money I’ve spent on the car are one set of tires, a few sets of wiper blades, and windshield washer fluid.

Since we announced our plans to move to Minnesota, I’ve gotten some questions about what we’ll do with the car. The current plan is that we’ll still be driving it. While there are certainly fewer Teslas in Minnesota than Washington, it’s still a great car. I would imagine there are fewer superchargers, but the only time I care about those is when I go on road trips. The number of chargers within 100 miles of my house is pretty irrelevant. And yes, the car is fantastic in the cold weather. (In November of last year, Tesla accounted for 31.2% of all sales in Norway.)

All that being said, I expect to be over 100,000 miles by that point. If you remember my original math, that was my predicted “break even” cost point versus the Ford Escape we would have purchased instead. In reality, we’re on track to hit that point sooner since gas is more expensive than I planned for. So if we get that far before selling or having a major problem, that’s a win in my book. How long will the car last? I don’t know. Maintenance costs are very low but the battery does degrade. We’re currently around 85% of our original capacity. For daily driving, it makes no difference but on a long road trip this could translate into an extra charging stop. I think that 85% number is a bit below average but it’s still well within normal bounds and the packs are warrantied up to 120k.

Trading for a refreshed Model Y is tempting though. The list of small new features has piled up over the years and I wonder if we should take advantage of the strong used Tesla market in this area before we move. But that brings in questions about higher sales tax and registration costs here too.

Another big disincentive to sell is that Tesla recently discontinued the inclusion of “Autopilot” on their new cars in an apparent effort to get more people to pay $99/month to subscribe to Full Self-Driving. I LOVE the Autopilot feature on our car and I would guess that at least half the miles I drive are with that feature enabled. I use it just about any time that I have cruise control enabled. The main differences between FSD and Autopilot is that FSD will change lanes on the highway, stop at intersections, make exits/turns to follow your path, etc. Autopilot is more like a cruise control that adds “stay on this road until I tell you differently” and it works all the time on any road or pretty much any weather condition. We’ll see if that decision sticks or not. A lot probably depends on which number is bigger: 1) the additional revenue from people adding FSD or 2) the loss in sales revenue from people who won’t buy the car without that feature.

So for now, there are no changes to the plan. We love the car and I’m happy with the way the cost numbers are working out.

Guest Bathroom Renovation

If you’ve been upstairs in our house, you’ve probably visited our pale yellow bathroom. Our main bathroom was originally yellow too, but we had that remodeled back in 2013. After living in this house for ~14 years and saying I was going to remodel our guest bathroom for about that long, we decided it was time to hire someone.

I wasn’t looking forward to the search because contractors out here are very busy and very expensive. Everyone seems to want their project to get a million likes on social media. We just wanted to get rid of the yellow. Here was our specific task list:

  • Remove yellow marble shower surround
  • Remove countertop, vanity, mirror, light fixture, and medicine cabinet
  • Remove yellow flooring
  • Replace the shower valve to a modern pressure balancing valve
  • Tile the shower walls
  • Install a new pre-built vanity, mirror, and light fixture
  • Install an LVT floor

If you’re into home improvement, you can probably see why I kept thinking I would do this. It would be hard and I would have to learn things, but it’s not impossible. When I chatted with the first contractor to get a ballpark estimate, I had more motivation to do myself. They said this type of project is usually $60,000-80,000. WHAT?!

A couple weeks before I was ready to dive in, some friends from church turned me onto their contractor. They said he was very reasonably priced, was willing to let the homeowner buy materials and do some of the work, etc. His quote was MUCH more reasonable and we quickly agreed to a deal.

My end of the project was buying all the supplies: tile, flooring, vanity, lighting, plumbing fixtures, etc. We used the same line of faucets and fixtures that we used in the main bathroom so that part of the decision was easy. We were going with a basic white, rectangular tile so that was pretty easy. Finding a vanity was a lot of clicking but I finally found a ~60″ wide, single sink, white vanity that was very well-built out of solid wood and I found a lighting fixture that was wide enough to not look goofy. The flooring was probably the hardest part. We had a big stack of samples in the house before we finally found one we liked that also happened to be in stock. Everything arrived at the house by the time we needed it except for the flooring which got installed about 15 minutes after I picked it up and brought it home. That one was a little too close for comfort.

I was shocked at how fast the contractors worked. Within two hours of showing up at the house to start the project they had fully protected all the flooring up to the bathroom and demolished the entire bathroom. By the end of that first day they even had the backerboard in place so they could start tile on day two. It’s awesome to watch people work with confidence and skill. For home improvement projects, I’m lucky if I have one of those and I rarely have both.

Since the original bid felt so good to us and because the company also had a major painting business, we tacked on having them paint the stairwell. It has needed to be patched and painted since we moved in but climbing up two stories on stairs did not seem fun. They also repaired and painted the whole front door wall and trim. It looks amazing!

I’ve been asked why we remodeled this when we know we’re moving. It’s mostly so that we don’t have a yellow bathroom in our real estate listing. While our house is far from fancy/modern for this area, that bathroom was especially unusual. Hopefully this new bathroom will keep a few more people flipping through the pictures in our listing.

From Batteries To Plugs

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!

Automatic Cat Feeder Improvements

We are blessed to have quite a few people who can help take care of our cats while we are gone, but when we are gone for less than 48 hours, it seems like overkill to coordinate that and take time out of their day. We have an automatic cat feeder which works pretty well, but it only takes one failure to lose a lot of trust in it.

When we were in Yellowstone last summer, we had planned to only have Megan come over every 2 days and just use the automatic feeder. But one of the first nights, I checked our cameras (yes we have a camera in the cat room) and it looked like the feeder was jammed. I don’t know why the cats weren’t eating it but something was clearly wrong, so not only did we then need Megan over there every day, but she also had to make a late evening run over to our house to immediately fix the situation. (Thank you Megan!) Ultimately I think the problem was that the divider chute didn’t meet up with the bowls well but there might also have been an issue with the food not having enough room to drop out of the machine and onto the chute.

We haven’t used it since then but we have a coule more quick trips coming up so I decided to improve it. Through a LOT of trial and error in Fusion 360 and lots of 3D prints, I eventually designed a new attachment for the dispenser which not only shouldn’t jam as easily, but it is the perfect height for the bowls we like to use, it holds the bowls securely in place so they don’t slide away from the feeder, and it holds a piece of cardboard between the bowls so that one cat doesn’t get intimidated by the other. It even has a little hook on the back that fits into a spot on the feeder to securely hold it in place.

I learned Fusion 360 through Bob Claggett’s awesome Fusion For Makers class, but this was the most complex design I’ve ever attempted and I had to learn a lot along the way. I was 20 versions into my first attempt before I trashed it and started a new one that ended up at 15 versions. But now I have a super custom solution that should work great! I’ve run a lot of cat food through it to verify my solution and so far so good.

Fusion 360 is very intimidating, and I have a long way to go, but I’m slowly getting to the point where I can bring more complex ideas to life. Being able to model anything and then print it out is amazing!

If for some reason, you want this specific model, it is posted on printables.com.

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!

Lego Masters

Our family loves the Lego Masters TV shows. If you’ve never seen it, it’s a reality show that features about 8-ish teams that compete each week to build according to a theme. A judge picks the winners and losers and sometimes people get eliminated. The concept isn’t rocket science but the execution of it can be great.

Multiple countries have their own versions of it. The US version is ok, but honestly, if you’re just getting started, I recommend going through the Australia version. The host, Hamish Blake, is fantastic, and the judge, Brickman, has tons of knowledge and insight. I think the contestants in these shows are better as well.

If you really want to start with the cream of the crop, watch Season 5 which is a competition of some of the best teams from previous seasons. You’ll miss a bit not having their back story, but the quality of the builds is unbelievable. The only downside to starting here is that I don’t think any season from any country lives up to this one.

The Australia episodes are a bit difficult for us to watch in the US but we’ve been able to find them on Tubi for free with ads. I avoid ads whenever humanly possible, so the fact that we watch this show even with ads says a lot.

Big News

Did you have a nice break for Christmas and New Years? Are you settled back in yet? Ok good, because we have big news: we are moving to Minnesota. (See? That title wasn’t click-bait!) It won’t happen right away though. We are planning this for the summer of 2027.

I realize that it’s going to be difficult for anyone else to understand the full picture of why we’re doing this, and honestly, that’s ok. We’re confident that this is a good move for our family. Some of the reasons are private of course, but here are some of the big ones:

  • In the summer of 2027, Elijah will be done with 8th grade. We’ve spent a lot of time researching high schools around here.
    • Our national church body operates a great high school down in the Tacoma area. We’d love to send Elijah there, but it would mean 5+ hours of commuting every day. If we moved closer, I’d still be within the radius where I’m required to commute to work at least 3 days a week starting in February so that’s unattractive too.
    • We’ve been through (literally) every Christian private school in the area and they were all rejected for adding/subtracting from the Bible. The current school we attend isn’t perfect either but it was close enough that we were comfortable working with Elijah as he went through it, but we couldn’t even find that situation for high schools.
    • We looked at non-religious private schools and mainly rejected those for cost. It’s not uncommon to find tuition prices north of $40,000/year.
    • Our public high school is very good, and this was our top choice if we didn’t move.
  • There are three great high schools in Minnesota that are affiliated with our national church body: West, St. Croix, and Minnesota Valley. We’ll be exploring those options more to figure out exactly where we want to land. Elijah has also lightly expressed interest in attending Martin Luther College so this will put him in touch with other high school kids thinking about that career path and also put us closer to the college if he does go there. If he chooses something else, there are plenty of other good schools to pick from (or we could always move again.)
  • In the big scheme of things, I don’t think we’d be called homesteaders, but we certainly want more land with room to have a big garden, an outbuilding or two, and maybe some animals. We currently own 1/6th of an acre and the bare land is valued at $700,000. That’s something like $4.2 million/acre if you could even find an acre of land to buy. We’ve always talked about moving further away from Seattle and Bellevue to spread out a little.
  • Tyla and I both grew up in the Midwest and furthermore, Tyla grew up southeast of Minneapolis. We feel at home in wide open spaces and empty two-lane roads. Contrast that with the view from our back yard where we can see 16 houses and endless traffic we sit in at all hours of the day on any day of the week. We are generally quick to say we love this area, but those feelings don’t always align with the current reality. The population has exploded in the last 20 years. That’s great for our property value, but bad for our comfort level.

There are definitely things we’ll miss around here. We have friends and family close by and there are few places in the country more beautiful than this area. The temperatures are mild, and our summers are incredible. We’re moving to a flat land of snowy winters, sweaty summers, and bugs. But, as cheesy as it sounds, home is wherever the three of us are. I’m hopeful that we’ll grow even closer together during this experience as we tackle this challenge together. And it’s also comforting knowing that wherever we land, there will be a church home waiting for us.

What about work? This is still a big question mark and could throw a wrench into our plans, but I can do my job from anywhere. I will need to get approval to work fully remote and talk to HR about the compensation changes that will come with moving to an area with a lower cost of living, but I’m hopeful that will all go smoothly. While there is an office in the Minneapolis area, I don’t expect I’d ever need to go there since nobody else on my team lives there.

Why are we announcing this now? In a blog post? We don’t know how to do this. This has been something we’ve been praying about for months. We decided we would go through Christmas and New Years like normal and then tell everyone at once so there were no secrets or groups of people with mismatched information. We wanted to get the news out so that we can start sharing this part of our lives.

There are many details left to discover over the coming year and a half. The first big step will be a trip to visit all three of those potential high schools. The hope is that all three feel like a good fit for different reasons, but we’ll take our learnings from that and see what real estate looks like. I can already tell you that when I property search around those areas, I have my search set to “No HOA” and “> 2 acres” and that turns up a lot of options that seem to fit the style we are looking for. We’ll see how those dreams play out.

I imagine that a lot of friends and family reading this will have a lot of questions. We’re happy to chat about it but please know that a lot of the answers will be “I don’t know yet.” We feel like this is the right move, but there are a lot of specifics to work out.

AI Coding Update

Let’s take a quick minute to update where we are at with AI in my daily job. It’s changing so quickly that it’s hard to organize my thoughts around it.

Over the last year (and even the last 6 months), AI coding agents have gone from “overhyped party trick” to “fundamental necessity”. A lot of that comes from advancements in models (Claude Opus 4.5 is my current favorite) but it also comes from us learning better ways to interact with the models. There’s still too much hype, but my personal daily reality has been permanently altered by these new capabilities. At this point, coding without AI feels as unthinkable as coding without StackOverflow or a search engine did last year.

Stepping back for a moment, it’s good to note that Large Language Models (LLMs) are a great fit for software development. If you think about training a model on the English language, it’s a mess because there are so many different styles and rules and unwritten rules and colloquialisms, etc. But with code, there the languages are strictly defined and there are intense levels of documentation for every piece of every language. This gives the AI agent a very well-defined playground to do your bidding.

What really pushed this tech over the edge for me was learning to start by having it generate documentation about the work it was going to do. I’d explain the requirements, have it generate a plan, and then iterate on that plan document until I was happy with it. Then I’d have the agent tackle pieces of the plan, step by step, verifying its progress along the way.

I can’t tell you how much faster I’m able to get projects done! There have been two giant projects floating around in the back of my mind for years at work, but I could never justify the time to do them. Not only did I get them both done in just a few weeks, but I did it in my spare time at work without slowing down the rest of my job. My output is skyrocketing and it feels like I have a new superpower.

I have no idea where this is going or how it’s going to change our jobs in the future, but I don’t think it will be too long before I’ll move up the “AI management” ladder. Instead of directly commanding one agent at a time, I can imagine telling a “manager agent” what I want and then letting it create its own agents to do different parts of the job and make sure they’re all still heading toward the goal. That’s potentially another order of magnitude increase in my output. After nearly 20 years at the company, I have a very long backlog of ideas to try, but now I’m wondering if that list is long enough. I can churn through ideas so quickly now and see which ones pan out.

“Will AI take coding jobs” is a common question but my answer is that if your job is typing in code, then yes, you’re in trouble. But if your job is seeing things that can be improved and solving problems, then this is an incredible tool amplify your impact. In that case, AI won’t take your job, but someone who knows how to use AI more effectively than you might.
