DIY Wireless Pool Thermometer

When we visited my parents last summer, they were talking about the idea of having a pool thermometer that they could read from inside. There are various options on the market already but none of them met their criteria. I went home thinking this could be an interesting project and Christmas gift.

While I’ve done electronics projects before, I feel like very much of a newbie and there was a ton of learning involved in the project. My first challenge was learning how to read temperatures with a sensor that would be submerged all the time. Some research led me to the DS18B20 waterproof temperature sensor and I found a nice tutorial about using it with Arduino. I bought a couple official ones from Adafruit even though there are cheaper versions on Amazon. I only needed one for the project but I figured there was a good potential for me to screw one up. I had some ESP8266 boards left over from the LED panel project and that seemed like a good fit for this project. The boards are only a couple bucks and they have WiFi built in. With a little breadboard action, I was able to see the temperatures from the debugging output of the board.

The next step was to somehow publish that data. There are endless options, but to keep things simple, I started with Adafruit IO. It’s free for the small amount of data that I’d be sending and there were good tutorials about using it with the ESP8266 boards. That was quite simple to set up and before I knew it, I had a temperature sensor that sent data to a website!

I was going to explore ordering a custom breadboard and I did start down that path but I got a bit overwhelmed trying to find all my specific parts in the tool. My circuit wasn’t very complicated, so I ended up just using some perf board and manually soldering the components in place.

I wanted to make it easy to replace all the individual components so I ended up using connectors in quite a few places. I put a headphone jack on the end of the temperature probe and it plugs into a jack in the box. Then the box jack has another wire that plugs into the board.

Before I could figure out the box situation, I needed to figure out how to get power to it and that ended up taking me a lot of time. I landed on a power socket that’s meant for RVs connected to a buck converter to bring the 120v down to 5v. It was bulky but I made it easier by removing the long cable and plug on the power socket.

That just left the box and for that I opened up Fusion 360 to make a custom box that I would 3D print. It had all the holes in just the right places, the lid fits snugly, and all the screws are countersunk. The only problem was that the standoffs I built in for the ESP8266 were too tall/thin and they broke but ultimately it’s not a big deal.

I was nervous about whether the WiFi signal would reach from their pool, but thankfully they don’t have any competing WiFi traffic in the area and it worked fine! I got Dad set up with the development environment so he could make changes to the code, and he had an idea to make the probe wire much longer and keep the box in the pool house. There are endless possibilities since I’ve basically handed him a prototype and walked away, but hopefully it will work at least for a little while! I’m expecting it to take a couple more iterations to work through bugs and maybe we’ll build nicer software for it, but at this point, I’m kind of amazed that it actually worked.

Monarch Money – 1 Year Review

It’s been over a year since I moved away from the dying Mint.com to Monarch Money to keep track of our finances. As with any tool like this, it takes a while to get everything hooked up and configured nicely, but now that it’s there, I really like it. My favorite part so far is the automated rules that do a great job of figuring out how I like to categorize our expenses. Now my periodic trips into the tool are more about reviewing the line items instead of manually categorizing them all. All that categorization is especially nice at the end of the year to look back and see where our money has been going and decide if that seems reasonable or not.

My only complaint is that it does not hook up to our Thrivent.com accounts, but I believe that’s a problem on Thrivent’s end. They were flaky with their connection to Mint as well.

If you don’t have a good way to keep track of where your money is going, I think you could do a lot worse than using Monarch Money. This isn’t a paid advertisement or anything, but I do have a referral code you can use that gets you a free month and then I get a month for free as well.

Christmas in Indiana

Living thousands of miles from where I grew up, it’s amazing to me how often we’re able to get back there. My parents were gracious enough to host the whole gang for Christmas yet again. There was a tiny bit of snow when we arrived and then it warmed up making travel simple. We made good use of the clear roads by heading down to see my 94-year-old Grandpa. Other than that, we had a couple church services, board games, good food, a chocolate factory with bison and dinosaurs, and a pile o’ presents. And oh yeah, Luke brought a giant 1.3 gallon beer to go with Dad’s craft beer sampler pack mountain.

I’ve gotten in the habit of putting together a quick video recap of the trip. It’s probably not super interesting to anyone else, but we enjoy looking back at them.

And here are a few pictures from the trip as well:

2024 Year In Review

As I sit here staring at this blinking cursor trying to remember what happened in 2024, I’m thankful that I keep this website going. I don’t post every day like I used to, but it is nice to have a record of our trips, my projects, and other family events (with some nonsense posts in the mix of course too.) So let’s flip back through the posts and see what happened this year:

We usually try for one big (I guess that’s a relative term that varies by family) vacation per year, but this year had two because Tyla got to go on her AGE-REDATCED’th birthday adventure to Leaping Lamb Farm. We had been there in 2022 for the first time and Tyla immediately wanted to schedule a return visit so we booked spring break week this year. We had to wait a year and a half for the trip but it was worth it. There were baby lambs and baby goats hopping and falling all over the place.

I took a solo trip in May to the 2024 PacNW Men’s Retreat and promptly returned home with food poisoning. Not only was that a horrible experience but I was really bummed to miss Pastor Dave Scharf’s talks. Little did I know I’d run into him later in the year… (Also, I’m happy to say that the restaurant that got me sick is now permanently closed. There appeared to be some serious health code violations, and I should have just walked away.)

We took a quick day trip down to Portland to see a professional disc golf tournament. It was such a fun day for all of us that we already have a tournament on our calendar for 2025. It’s a small sport but big enough that the pros are mind-bogglingly good. It was amazing to see in person what they’re capable of instead of just watching it on TV. Elijah also got to watch his disc golf teacher play and then got to take a picture with her on the first tee!

Pretty much every summer we try to make it back to my parents’ house in Indiana for some pool fun. They surprised us this year by installing a diving board and it got a lot of use! Given how far away we live, I’m thankful that Elijah gets to spend so much time there and get a little taste of what it was like where I grew up.

Our “official” big vacation was a cruise to Alaska. This was the third cruise for Tyla and me, and we knew Elijah was excited to see Alaska, but when we told him it was a cruise, it was a hard sell. He really didn’t want to go. Ask him what he thinks about cruises now! I’m thankful he kept an open mind, and he has now done a complete 180. It wasn’t nearly as relaxing as our previous cruises, but it was fun to experience it through his eyes.

We squeezed in one more quick family trip to Moses Lake in central Washington so we could drive up to the Grand Coulee Dam. We wanted to show it to Elijah and we were also able to snag a couple more counties as we try to color in the entire map of Washington counties. I think we’d all agree that the highlight of that trip was our ride on the tiny Keller Ferry. Our cars have been on a lot of boats, but never one that small!

As you may have noticed, pretty much all our trips involve all three of us, but in October, Tyla and I took our own trip out to New Ulm, MN for a weekend at Martin Luther College. We’re getting more involved with supporting the school and were involved in some meetings. A huge thank you goes to Megan for staying at the house and watching Elijah!

Then finally, this year we spent Christmas in Indiana. Two trips to Indiana in one year! I know it’s a lot of work for my parents to host us all, but we really appreciate being able to spend Christmas with everyone.

At home, I felt like I had a lot less free time to do projects. I’m not sure if that’s because I was a lot busier with my volunteer work at church or because I was lazier in the evenings. It’s probably a combination of both. My woodworking Instagram account does remind me that there were quite a few projects even though none of them were huge. I made a walnut trash can with some interesting angles, a keepsake box made with wood from an old cross with Elijah’s school logo on the lid, a walnut tissue box holder, a coat rack, a kids bakery sign, a cat bed, and an updated silverware tray. There are some big projects underway now but those will probably land in 2025. And while it’s not woodworking, I replaced the rotten wood backsplash in our kitchen with tile. It was my first time doing tile and it makes me smile every time I do the dishes because I’m not staring at something I need to fix.

I think the biggest change for me personally this year was mostly dropping off of social media. I still post my finished woodworking projects to Instagram and I post for our church Facebook and Instagram accounts, but I have broken the habit of doomscrolling and it feels amazing! I removed the Instagram icon from my phone’s home screen and left that spot blank. It was shocking and scary how many times I would pull out my phone and click that spot. That just reinforced my desire to stop. I set a rule for myself that I would only go through what the people I follow had posted once per week on Friday nights, but now I find myself going multiple weeks before I remember to check in. This feels much healthier and certainly removed a lot of pointless screen time from my day.

To combat the relentless acceleration of the calendar and ever-dwindling free time, I’m trying to be even more intentional with my time. Making task lists for each day, removing wastes like social media, and trying to schedule family activities on a regular basis are all helping. There’s also the problem of having too much stuff to cram into a week, but I haven’t figured that one out yet. There’s always next year!

Wrapped

Lots of websites are doing these “Wrapped” style emails where they show statistics about your usage of their service. Here’s a sampling of mine:

Spotify

I listen to a lot of Spotify while I’m working and I found myself listening to a playlist of Christian radio songs that I listened to in the ~90’s. You can listen to it here (no subscription needed if you’re ok with ads.) That combined with our reading of the Wingfeather Saga got me into listening to a lot of Andrew Peterson music.

  • Listened for 51,049 minutes
  • Play 4,898 songs
  • Listened to 1,249 artists
  • Top songs (mostly because these are two of my favorite albums)
    • FFH – One of These Days
    • FFH – Big Fish
    • Caedmon’s Call – Thankful
    • FFH – Power In His blood
    • Caedmon’s Call – Table for Two
  • Top artists
    • Andrew Peterson
    • Third Day
    • George Strait
    • The Arcadian Wild
    • Josh Turner

Pocket Casts

This one was less interesting to me because I already know which podcasts I listen to regularly, but here it is anyway:

  • 23 different shows and 403 total episodes
  • 12 days, 17 hours, 5 minutes of listening
  • Top podcasts
    • Stuff You Should Know
    • Making It
    • Cordkills
    • No Dumb Questions
    • Wood Talk

Duolingo

I started doing Duolingo in 2020 as a way to make good use of the time I previously spent commuting and I’m still doing it every day.

  • Completed 2217 lessons earning 96,226 XP over 3201 minutes
  • Current streak is at 1529 days

Goodreads

There are so many books that I’d like to read that I really enjoy using Goodreads to keep track of them all. My Kindle syncs with my Goodreads account but given how old my Kindle is, it crashes every couple weeks and prematurely marks books as completed so I don’t put much confidence in the things like the number of days that it takes me to read a book.

  • 31 books read, 9827 pages read
  • Most common book read: Percy Jackson and the Olympians
  • Least common book read: Taboo (Read this!)
  • Highest rated book read: The Wingfeather Saga: The Warden and the Wolf King

UDisc

I played less disc golf than last year, but here are my stats.

  • Steps: 42,300
  • Holes played: 141
  • Total throws: 465
  • Distance thrown: 7 miles
  • Courses played: 6

Trakt

I use Trakt to keep track of all the movies and TV shows that I watch. It’s great for hopping around between shows and remembering our show progress as we add and remove various streaming services.

  • Elijah and I watched 121 episodes of Mythbusters
  • The show Tyla and I watched the most episodes of was The Chosen.
  • The show we all watched the most episodes of together was The Wingfeather Saga.

Untappd

I track all my beers and have fun seeing how many different ones I can experience.

  • I tried 112 new beers from 64 breweries covering 31 different styles.

Merry Christmas

LUKE 2

THE BIRTH OF JESUS

1 In those days Caesar Augustus issued a decree that a census should be taken of the entire Roman world. 2 (This was the first census that took place while Quirinius was governor of Syria.) 3 And everyone went to their own town to register.

4 So Joseph also went up from the town of Nazareth in Galilee to Judea, to Bethlehem the town of David, because he belonged to the house and line of David. 5 He went there to register with Mary, who was pledged to be married to him and was expecting a child. 6 While they were there, the time came for the baby to be born, 7 and she gave birth to her firstborn, a son. She wrapped him in cloths and placed him in a manger, because there was no guest room available for them.

8 And there were shepherds living out in the fields nearby, keeping watch over their flocks at night. 9 An angel of the Lord appeared to them, and the glory of the Lord shone around them, and they were terrified. 10 But the angel said to them, “Do not be afraid. I bring you good news that will cause great joy for all the people. 11 Today in the town of David a Savior has been born to you; he is the Messiah, the Lord. 12 This will be a sign to you: You will find a baby wrapped in cloths and lying in a manger.”

13 Suddenly a great company of the heavenly host appeared with the angel, praising God and saying,

14 “Glory to God in the highest heaven,
and on earth peace to those on whom his favor rests.”

15 When the angels had left them and gone into heaven, the shepherds said to one another, “Let’s go to Bethlehem and see this thing that has happened, which the Lord has told us about.”

16 So they hurried off and found Mary and Joseph, and the baby, who was lying in the manger. 17 When they had seen him, they spread the word concerning what had been told them about this child, 18 and all who heard it were amazed at what the shepherds said to them. 19 But Mary treasured up all these things and pondered them in her heart. 20 The shepherds returned, glorifying and praising God for all the things they had heard and seen, which were just as they had been told.

Buy Another EV?

In December, EV and hybrid vehicle sales hit another record (this happens regularly because the numbers keep growing.) 8.9% of all vehicles sold in the use were battery electric and 10.6% were hybrids. EV skeptics sometimes will brush aside those numbers saying that people are dumb once but won’t be fooled twice. But check out this study of over 23,000 EV owners which states that 92% of battery electric vehicle (BEV) owners would buy another one and 4% would switch to a plug-in hybrid. Now, I take that with a grain of salt given that this group specifically exists to promote EV ownership, but we can at least take away that maybe there are a lot of people who really do love their EV and would not want to go back to a gas engine.

I often think about this for our situation. We’ve already put 55,000 miles on our Model Y in just 2.5 years of ownership and it is a perfect fit for our situation. In these posts, I repeatedly refer to making the switch because it was going to save us money over a Ford Escape. I do not mean to imply that it would automatically save everyone money over a Ford Escape, but in OUR situation, it’s a great fit. I would definitely replace it with another EV and it would probably be another Model Y. The price has come down since we bought it so the math is even easier. The only difference is that if we replace it after our son moves out then I might consider downsizing to a Model 3 instead of the Model Y, but we’ll probably want to replace it before then anyway given the 20,000+ miles/year that we’re putting on it.

But we also own an F150. Would I replace that with an EV if it died? Probably not. It is still nice to keep one foot in the gas world. We drive it very infrequently and only use it when the other person is already using the car or when we need the utility of the truck. But it’s still nice to know that we could use it if the EV wouldn’t quite work yet. For example, we’re planning a trip to Yellowstone, and it has been nearly impossible to find a convenient AirBNB with a good charging setup. I’d have to rely on the supercharger right outside the park. With the amount of driving we’ll be doing in that giant park, that might still be a place where we prefer to have the truck with us.

I suppose the skeptics would disagree, but I believe that the EV scenario is only going to get smoother and simpler from here on out. We intend to keep that truck for a very long time so maybe in 10 years the pro/con list will look a little different, but as of right now, we’re already in the “yes, we’d replace our BEV with another BEV” camp.

Silverware Drawer

I don’t remember how long ago it was, but many years back I built a custom silverware organizer to fit inside of our drawer. I did it in solid walnut and box-jointed the edges. It has worked well and it makes me happy every time I grab a utensil.

Fast forward to more recent times and we bought new silverware. We went through a lot of options before finally landing on this set and everything was great about it except that the knives were just a tad bit too long for the organizer.

After just ignoring it for too long, I finally took action. The organizer originally had dadoes to hold all the slots in place but thankfully I hadn’t glued those in place. I took out the dividers, sort of filled in some of the dadoes as best I could, made new dividers that were the right size, and then glued and nailed them into place. It was a bit tricky to align everything without the dadoes and there were some mistakes that make me question how long this will stay together, but so far so good! I just repeated the original finish of rattle can lacquer.
