2025 WELS Synod Convention

The church I attend is part of a national church body called the Wisconsin Evangelical Lutheran Synod. Why? There are things that are difficult for individual churches to do such as sending out missionaries and training new pastors, teachers, and staff ministers. So we band together to do those kinds of projects as well help keep each other teaching directly what the Bible says. Every two years, the synod holds a convention with delegates from around the country to review our current status and make plans for the future.

This is the 175th anniversary of our synod. It started so small and there were many times where we were on the verge of heading down a bad path, but ultimately, our truth did not bend around popular culture and our beliefs have remained consistent regardless of what is trending.

From that humble beginning we have now spread out around the world. I was on a committee that was focused on gathering information from our mission board so I got extra insight into the amazing work being done around the world. The international Christian community is exploding in places you might expect, but also in places that would shock you. (Some of those places can’t be reported since it would put lives in danger.) Inside the US, we are working to plant 100 new missions within 10 years and also to strengthen/restart 75 of our existing ministries. We’re two years into that plan and it’s going well, but as costs rise, it makes the work more challenging. Regardless of where the missionaries were located, they had incredible stories to share about how the gospel works in individual hearts.

The convention was held in New Ulm, MN at Martin Luther College. That’s the same place Tyla and I have been visiting to work with their leadership on some ideas. It’s a special place because every one of our pastors, teachers, and staff ministers goes through that school and receives the same solid, doctrinal education. (Pastors continue on for another four years at seminary.) It’s fun being there when the students are on campus, but it was also interesting this time to be there with ~400 other delegates. Many extra people came to the opening worship service and it was a treat to hear 800 people singing together. Breaks and meals were full of interesting conversations and when meetings finally ended late in the evenings, there was social time with drinks from Schell’s Brewing. The cool beer was a welcome freshment because it was in the low to mid 90s with extreme humidity. I was so thankful that I skipped the free lodging in the dorms and got a room at a hotel. The AC (and privacy) were very welcome.

It was a little weird being on campus without Tyla, but she and I will be back there in a couple months for another meeting. I did enjoy seeing familiar faces from the campus staff and meeting new ones as well. I got a tour of some of their tech services too and hope to continue that conversation in the future.

It was four very long days but I’m so happy that I could attend. Since we have so many churches and there are so few delegates, it’s a rare opportunity that a church gets to send someone. This could very well have been a once in a lifetime opportunity for me, but the memories of this convention will last that long.

Summer in Indiana 2025

I’m thankful for how often we get back to Indiana given how far away we live. Summer is a fun time for us to visit since Dad and Mom have a pool and that is a big hit with the family.

Our trip this year included:

  • A visit to the South Bend Chocolate Factory where Elijah got to chat with the owner who gave him a free shark tooth from their dinosaur museum.
  • A walk along the St. Joseph River in the evening to see their light display.
  • Visiting with Grandpa, Aunt Laura, and Mari
  • Rafting down the Eastrace Waterway
  • Exploring the beach, lighthouse, and carousel in St. Joseph
  • Roasting marshmallows over the firepit
  • Target practice with Elijah stepping up to his first experience with a .410

And all of that was interspersed with lots of conversation, swimming, and delicious food. Thank you Dad and Mom for hosting all of us!

EGO Mower Review

After replacing most of my yard equipment with EGO tools, I had hoped to wait a while to replace my push mower, but that hope didn’t pan out. After 14 years, the deck was finally rusting through and eventually it fell apart while I was mowing.

But after having so many surprise/extra bills this year, I thought this would be a good opportunity to be responsible and also teach Elijah that we can fix stuff instead of throwing it away. I ordered a new deck for about $120. That eventually arrived and Elijah and I headed to the garage for what should have been a simple replacement except… there were a few bolts that were complete unrecognizable lumps of rust. I messed around for a long time trying to figure out how to get them out, etc and by the time I started adding more replacement parts to the bill, it just didn’t make sense anymore.

Thankfully I was smart enough to order the replacement deck from WalMart so the return was very easy. And doubly thankfully, EGO was having a huge sale on exactly the push mower that I had picked out. I ended up with the LM2130SP. It normally ships with a 7.5Ah battery and a rapid charger and costs $749. But with the sale, I got it for $599 and that included a free 5Ah battery.

I brought it home to mow for the first time and see how many batteries I really needed. I went through the whole routine: edging, string trimming, mowing, and blowing. I did that all with a single 5Ah battery! At this point I had a 2.5, two 5’s, and a 7.5. So I headed back to the store and returned my free 5Ah battery (on the receipt it prorated the savings across the multiple items) and in the end, I got that $749 mower for $386. (All prices are without tax.) A new version of the cheapo gas mower that I was replacing was $350 so I felt like this was a fantastic deal!

I’ve only mowed a couple times with the new mower but I’m happy with it. It is self-propelled though my yard isn’t big enough for that to matter. Plus, this mower is so light! It’s also incredibly quiet to the point where you can easily carry on a conversation with somebody while it’s running. An added benefit that I hadn’t considered was how it doesn’t care what orientation it’s in. With a gas mower, you have to be carefully which way you tip it, but with this one, I just finish mowing, flip it over and blow out the grass. I even saw some people who would fold it up and store it on end in their shed!

I picked this model because theoretically it has more torque than my old mower did. I currently have no concerns about having enough battery power to easily get all my work done on my small yard, but we’ll see how it goes when the grass is really growing quickly and I’m a few days late in mowing.

I’m now at the point where the only gas engines I own are the pressure washer, generator, and truck.

And as for that old gas mower? Elijah and I took the engine as far apart as we could so I could explain the four strokes of the engine, let him feel the valves moving as the crankshaft turned, etc so we did get some education out of it.

A Coaster Journey

I’ve always been intrigued by wood inlays on the CNC. I’ve tried a few times in the past but I could neve get the precision I needed to make it happen. For Christmas, I received a BitSetter for my CNC which lets me change bits in the middle of the job and zero the height of the new bit to exactly the same as the previous one. When doing inlays, you need to first use a regular bit with a flat end to carve out the big areas and then you use a “v bit” to make the angled sides. If those two bits aren’t zeroed exactly the same, you won’t end up with a precise piece. After that you have to cut the plug to fit into it going through the same bit change process.

I chose to use the Martin Luther College logo since Tyla and I have been doing some much work with them and because it seemed like a good medium-detail goal to shoot for. And I’ve been shooting for that goal for months and months. Granted this is very much a start/stop project as I try to find 30 minutes here and there throughout the week or on the weekend to make progress.

I learned so many things along the way. This post would be absurdly long if I wrote it all out in detail but here is a quick summary of the learnings and improvements I made in the process:

  • Holding the work pieces down is difficult when making coasters. Pretty early on, I made a jig out of MDF that would perfectly hold the coaster but still have finger holes on the outside so I could extract the coaster.
  • The jig worked well but the coasters would spin so then I started cutting my coaster blanks with a little nub that fit into one of the finger holes so that it wouldn’t spin. I could easily cut that off at the end.
  • I messed around with different angles of bits: 60, 30, and 11. The sharpest bit didn’t work because the remaining slivers of wood were too fragile. The 60 degree bit was ok, but ultimately I liked the 30 degree best because it let me cut deeper even in areas of fine detail.
  • To remove any inconsistencies, I would spend time running a program to face each piece before cutting it to make sure it was perfectly level.
  • You have to glue EVERYTHING when you’re putting the plug into the base. I would use a tiny brush to carefully get glue everywhere on both faces but going fast so the glue didn’t start to set up.
  • I thought of various ways to remove the extra part of the plug, but eventually I just put it back on the CNC in my jig and let the CNC cut it off.
  • Glue would inevitably seep into the fibers in the top of the wood so I expanded my cut path just a tiny bit. Since I was make an angled cut, this meant I could remove the top couple hundredths of the coaster to perfectly remove any extra glue marks.

I had about 12 steps to the process of making a single coaster and it took me hours to complete one. And in the end… I could never get it good enough to satisfy me. There were always some little gaps between various parts of the logo. I tried using brown glue to make the gaps less obvious and I tried filling them with superglue and then jamming sawdust into the cracks. The superglue trick got me the closest but it’s still not something I’m proud of. So I did something I rarely do: I gave up on it. For now. Below you can see all of my numerous attempts as well as a solo shot of the closest I could get.

But I didn’t totally give up. I decided to scale back my dreams and instead of inlaying one type of wood into another, I would pour tinted epoxy resin into the logo that I had carved out. Despite being the first time I had ever worked with epoxy, this was almost an instant success! Not only did it look amazing but it also took me only about a third of the time (except for the 24 hours of cure time.)

There were still learnings to go through with the epoxy like dealing with bubbles that come to the surface as it cures, figuring out how the walnut soaks up extra epoxy around the logo pocket, keeping sawdust out as it cures, etc, but those were much simpler and I’m very happy with the result. I was even able to switch the logo and get a decent coaster on my first attempt.

After working on this so long, I’m kind of stuck in this mindset so I think I’m going to make a bigger jig and try to batch some of these out. They will make nice gifts and I’m sure I’ll experiment with other woods and other logos. I’m also interested to try doing a multi color pour. That would involve cutting part of the logo, pouring a color, cutting another part of the logo, pouring another color, etc. It feels a little silly to spend so much of my year on this one project, but I’ll keep going as long as I’m enjoying it.

Ike Kinswa State Park Camping

For many years, we have gone on a summer camping trip with Tyla’s family and the tradition continued this year. I don’t think most of us had heard of Ike Kinswa State Park before but we decided to give it a shot. It’s located northwest of Mt. St. Helens and southwest of Mt. Rainier.

We arrived on a Saturday and left on a Tuesday to try to avoid some traffic, and the traffic part worked well but it made booking difficult. State parks book up extremely quickly so you need to jump online right at 7am, 9 months in advance of the first day of your trip. Since our trip started Saturday, that meant that all the Thursday and Friday campers got first dibs. Thankfully we still found a couple pretty nice sites close together.

The park itself was nice. It sits on a reservoir behind one of two dams on the Cowlitz River. We spent Sunday driving around to explore the dams and play disc golf. On Monday we went up to Paradise Visitor Center on the south side of Rainer. Some of us took a short (but steep) hike up to Alta Vista. The trail almost had too much snow for us to make it but we did get to the top of the crest. The weather was perfectly clear and it was fun to point out the hikers going up to Camp Muir. I would love to do that hike with Elijah sometime.

All in all, it was a great trip. I dont’ know that we’ve had many trips with nicer weather. It was in the low to mid 80s during the day and cool enough at night to sleep easily. Thanks to Don and crew for getting the camper ready for this one trip each year and then putting it away again! It makes it a lot easier to do all the cooking and cleaning from the trailer.

Now we have a couple months before it’s time to figure out where to go next year…

EGO Equipment Review

When we bought this house, I purchased a simple push mower and a multi-head motor with string trimmer, edger, and blower attachments. That setup has served me well for 14 years and while they were showing their age, I didn’t have a strong reason to upgrade, and yet, here I am with new electric tools.

It all started when a friend who sells this stuff helped me get started with the EGO multi-head system. I ended up with the string trimmer, edger, and hedge trimmer attachments as well as a blower and an extra 5Ah battery to go with the 2.5 Ah battery that came with the multi-head unit. The gas mower remains for now, but I will eventually replace it with an EGO push mower.

The switchover to battery had been imminent anyway. My old motor was leaking more gas than it consumed and I knew I wouldn’t put the time into fixing it when I wanted to switch to battery powered tools anyway. As an added bonus, the blower is now easy enough for Elijah to use and he thinks it is fun so things stay much cleaner! I admit that these tools are also more fun for me to use too so I’m doing a better job of keeping up with all the edging and trimming around our yard.

It took a little thinking about where I was going to fit these tools in my limited shed space since they hang a bit differently than my previous tools. I was happy to find a robust 3D printing community around the EGO tools so I was able to print a holder for the main unit along with holders for the batteries and blower.

These tools still aren’t cheap but it’s helpful that the major investment of the battery can be shared among all the tools. I’m also excited by the inverters that they sell, especially the 3000w model. I hope that some day they will come out with a 240v inverter which I could use instead of our gas generator to power our house for short bursts of time and then save the gas generator for multi-day outages.

Best of YouTube

It’s time for another “Best of YouTube” post! I haven’t done one of these in about 9 months but I do keep notes that whole time on the ones that I think might be worthy. These are the three that have bubbled to the top.

Donut Media started the list last time and this time we start with the heart and soul of Donut (Jeremiah and Zach) who left to start the Big Time channel. They have an amazing deep dive into what it takes to become a MotoGP racer. If you like F1, you might love MotoGP. The tech level and story lines are just as strong, but the racing is even closer and higher stakes. This video gives you a good idea of the incredible lifelong dedication that it takes to race at the highest level.

I love trying different craft beers and I recently logged my 1500th distinct beer on Untappd. The How to Make Everything channel has a long series of videos walking through history and learning how things were made. This video dives into four types of beer and why they are historically important. I feel like I know a lot about beer but there was still a lot of great content in this video.

It’s hard to communicate what it feels like to be a software engineer, especially in my role where I’m reviewing other people’s designs and providing feedback about what might go wrong or how a different solution might be better. People call it “thinking outside the box” but it’s more like starting with “why does the box have to exist?” Mark Rober published a video on his Crunch Labs channel that did a good job of communicating the feeling of being an engineer.

As an aside, the build box subscriptions from Mark Rober’s Crunch Labs are fantastic. We’ve tried some others but this is one that I’m happy to keep paying for. Not only are the builds very high quality and educational, but he makes a special video for each one that gives a ~10 minute science lesson related to the build.

Weekend in Spokane

Sometimes we try to squeeze in a quick random weekend vacation, but there are so many great options, how do we decide what to do? To help with this, we kind of fell into the odd goal of trying to touch every county in Washington with our electric vehicle. The bar is very low. We just have to drive through it and while I try to limit the times we just drive in/out of a county to say we were there, it’s ok if that’s what happens. We invented the challenge so we can invent the rules and we can change them later if we want to!

We’ve been doing this for a while so the counties are getting harder to hit. For this trip, we targeted the northeast corner of the state. There are some really interesting spots in that area. For example, Crawford State Park has an amazing cave system that I would like to explore. But when you try to cram a bunch of stuff into a quick weekend trip and group a couple counties together, it gets tougher.

The itinerary for this trip was that we would drive to Spokane on Friday evening. Saturday we would do a counterclockwise loop north and west of Spokane and then Sunday we would drive back. And of course, we would stay at a Best Western Plus which Elijah thinks is the best hotel chain in the whole world. That status got a bit of a blemish when we pulled up and found out that their pool was closed for repairs!

I chose the Liberty Lake hotel because it was right across the street from a Tesla service center and Supercharger. That was very convenient and made staying there worth it even with the hotel being on the east side of Spokane.

  • Our tour started with driving north to Pend Oreille County Park. The park had a disc golf course but it wasn’t very well kept so we decided not to play and continued heading west.
  • Our next stop was breakfast-all-day at Hunters Holy Grub. We had a seat next to a window with a very active hummingbird feeder which Elijah and I enjoyed watching while Tyla pet the dog that was trying to sleep on the couch.
  • Our main stop for the day was Fort Spokane. I didn’t expect it to be super impressive (and it wasn’t) but to make things a little more interesting, I had AI create a ~15 minute podcast about the history of the fort. This ended up being incredibly interesting and provided great context as we walked through the museum and old buildings. I uploaded the podcast to YouTube with a static image if you are interested in hearing what it created for us.
  • On our way back through Spokane, we stopped at Riverfront Park where we tried the gondola over the falls (not worth it) and visited the trash goat (obviously worth it.)
  • Dinner was at the delicious No-Li Brewhouse

Our whirlwind tour of those counties was fun but our trip wasn’t over because on Sunday, we were invited to a graduation party on the Olympic Peninsula (west of our house.) We didn’t want to miss the opportunity to connect with old friends so we made the drive back home, past our house, and over to the party.

By the time we were done, we had traveled 989 miles. It was probably too much driving but we crammed a lot in and collected 5 new counties along the way. Below is a map of our route as well as an image showing the counties we have hit in total.

We have touched red counties with the Tesla. Blue counties are only with the truck.

Leavenworth Chocolate Tour

A couple weeks after Mother’s Day, Tyla finally got her Mother’s Day present. Elijah and I put together our own “chocolate tour” of Leavenworth. There are so many shops there but we used to go to the same one or two every time. But before hitting the sweets, we made a couple other stops.

The first was for the new-ish alpine coaster. Each car on the track holds one (or possibly two) people and you have a hand brake. The brake is not necessary and will annoy the people behind you, but it exists and a lot of people use it. The track is built onto a steep hillside right as you come into town from the west side. There are various YouTube videos if you want to see what the ride looks like, but in general, we all give it the thumbs up, at least to experience once. If you’re a fan of rollercoasters, the thrill level is pretty low, but if you’re a nervous rider, this is good because you can control your speed. It’s worth a visit.

Next we had lunch at Blewitt Brewing. We hadn’t been there before but we enjoyed our pizzas and I enjoyed some beers. They don’t necessarily do flights of beer, but they sell 5oz pours and you can get however many of those you like. I logged (via Untappd) my 1500th different kind of beer there!

Then finally it was time for the chocolate tour! Here are the places we went:

I won’t review them all individually, but it was a blast! It was so fun to explore business and buildings that we don’t normally go in and some of these will definitely get a second visit. This was especially good timing because Rocky Mountain Chocolates used to be our favorite stop by default, but the “Leavenworth Chocolate” business that replaced it is so bad I can’t imagine they will still be there next year. I’m glad we have great alternatives.

Happy Mother’s Day, Tyla!

AI Video Generation

Do you remember when Dall-E came out and people were amazed that you could generate a picture of a tomato driving a tractor? Those images were amazing at the time but already seem ancient in terms of quality and capability. That was only 4 years ago and now we’re well into examples of convincing AI generated video! Google Veo 3 is the latest video generation tool to make waves. Seeing is believing and while there are many examples floating around, I appreciated this video’s overview of what Veo 3 is an is not capable of.

As with all things AI, you have to remember that however you judge the quality today, it will be unimaginably better in 6-12 months.
