The Price Of Legos

Yes, I know the plural of Lego is Lego, but in my world, the plural is Legos. Deal with it. The other way sounds too pretentious. It’s like calling that fancy sports car a “Porsch-uhhhhh.”

Now that we’ve got that out of the way, let’s talk about the price of Lego pieces (see what I did there?) There are entire websites devoted to the economics of Lego sets. One good example is brickpicker.com. There are also some great breakdowns of the average price per piece by year and also by Lego genre. My parents will notice that when they were buying me lots of Legos, prices were coming down from their peak of $0.40/piece. Note that these numbers DO account for inflation. Today, a good rule of thumb is $0.10/piece is a good deal. Some sets can still be quite a bit more than this.

When you’re buying used Legos at a garage sale or thrift store, it’s probably easier to think in terms of weight. Advice varies a bit here, but in general if you shoot for $5-7/pound, you’re getting a pretty good deal.

Tyla shops at our local thrift stores pretty regularly to find clothes and toys for Elijah. I went with her once and was excited to see a small bag of Legos for sale. Ever since then, she’s been on the lookout and has had some small scores. Last week she sent me a photo of an entire wall of bags of Legos! We had a hard time deciding how much was “too much”, but it was such a good deal, we didn’t want to miss out. She ended up grabbing twenty bags for about $75.

The total haul weighed in at 14.5 pounds which puts us at $5.17/pound. I counted out a sample of the bricks, weighed the sample and then estimated that she bought about 5500 pieces for a price of 1.4 cents/piece.

The only way this wasn’t a good deal was if Elijah doesn’t like to play with Legos. But even if that happens, we could sell this for a profit. Combined with my Legos that are still in Indiana, he’s going to have an incredible amount of building options at his fingertips!

Individual Contributor

At work we have two career tracks: management and individual contributor (IC). It’s a pretty nice setup because you can switch back and forth at will, and the compensation is the same on both tracks. So theoretically you can be an IC that makes as much money as the CEO. You can decide whether your definition of success means climbing the management ladder or becoming a technology expert.

I started my career here as an IC and then moved into the management track about two years later. Now, six years after that, I’m bouncing back over to the IC track. It’s a change that I’ve been pondering for a while, and I jumped on a good opportunity when it appeared. This is really the first big voluntary change that I’ve made at this company so there is a bit of trepidation, but overall, I’m not going that far. I’ll still be working on the Power BI offering, but I won’t be as specifically involved with Power Query. My new role focuses around helping each of the Power BI teams give the best customer experience possible, specifically by giving them the data they need to react to issues with the service and tracking overall metrics to report our service health and usage. It gets me into a lot of big data, data scientist work. It’s new to me, but that’s what keeps work interesting and challenging.

Yard Project Update 4

While it might not look that much different than a week or two ago, we’re crossing some major work items off the list. The drainage is completely done and covered up. We dug trenches for irrigation, laid the pipes, installed the heads, and filled in the trenches. All that’s left there is hooking up the controller. We even installed a bit of sod along the driveway. I think we’re going to sod the back yard instead of seeding. It’s a pretty small area so the cost isn’t huge, and it will get us a nice result sooner. Don and Logan stopped by to help me set three more fence posts along the wall.

The biggest remaining puzzle piece is the fence. I’m hitting that hard now and hope to make good progress over the weekend if the weather cooperates.

We are 227 hours into this project and doing pretty well with the budget. It’s a ton of work but it’s fun to see it start coming together. My life right now is pretty much wake up, go to work, come home, work in the yard until 9 or 10, go to bed. Tyla has been great putting in extra hours to take care of Elijah when I’d normally be helping out! We’re both eager for the project to be done so things can return to “normal” and we can enjoy the fruits of our labor. I’m able to list out the remaining work in quite a bit of detail which means that we’re getting closer to the end. At least it’s measurable with a pretty high confidence rate.

Throwback Thursday – 1985 Cat

During one of our school devotions in kindergarten (or maybe 1st grade?), Miss Loescher covered Matthew 7:7-11. My childhood brain interpreted the lesson as “I can get anything if I just ask for it!” To test this out, I went home and asked my parents if we could get a cat. They immediately replied, “Yes.” I was stunned. It worked! How far would this go? “Can we get two cats?” “Yes.” WOW! It turns out they had already been talking about this so I just had good timing, but at the time I was pretty amazed at how applicable that particular Bible devotion was to my life.

At the pound, Rachel and I each got to pick out a cat. After we had picked them out, we were told that we had picked two cats from the same litter. Rachel named hers Slinky and I named mine Buttercup. I know Rachel’s was named after the toy, but I don’t know how I came up with Buttercup. I would like to think it was a Princess Bride reference, but that movie hadn’t come out yet and I hadn’t read the book.

Those cats lived to be pretty old. I was in college before either one of them died. That’s pretty amazing considering how much time they spent out in the woods hunting and being hunted.

Also, that’s an awesome belt buckle.

Tips For Building A Fence

I am far from an expert on fence building so after reading a bunch of articles on the web and enlisting some help, I built one wall of my fence before starting on the rest of it. This turned out to be a good decision because I could make all my mistakes on a smaller scale and then move more quickly on the rest of the fence. Here are some of the tips I picked up along the way:

  • I used 10ft pressure treated 4x4s. You can get away with shorter posts but you have to be really careful about the depth of your hole. I prefer to leave them long and then saw off the tops at the very end of the project.
  • Set the corner posts first. This allows you to string a line between them and make sure the interior posts are all perfectly aligned.
  • Once you’ve determined where your posts sit (roughly every 8 feet), dig a hole that is roughly 10” in diameter and 3 feet deep. Dig so that the post will be centered in the hole once it’s lined up with the string.
  • Put a few inches of pea gravel or clear aggregate at the bottom.
  • You’ll need two people to line up the post. Attach a cheap 8ft piece of wood to the post, pound a stake in the ground and then screw the wood to the stake while holding the post perfectly straight in that direction (use a 4ft level.) Repeat for the other direction. Do this all the way down the line.
  • Mix your concrete and pour it in being sure to push the concrete around the post and work out any bubbles. Let them dry for at least a day before continuing.
  • I bought pressure treated wood for the rails, but you can probably get away with something else if you want to save money.
  • String two lines between your corner posts at the height of each rail. The bottom rail is about a foot off the ground and the top rail is right at the top of your planks.
  • Make sure you get those rails level or you’ll have a goofy looking fence. I used a nail gun to attach the rails to the posts. I was able to do this step by myself because I screwed in a temporary board on the opposite post to hold the rail in roughly the right spot until I attached both sides.
  • Attach the planks. This is where a nail gun really comes in handy. I’m using a 15-gauge finish/trim nailer with 1-1/2-in. galvanized nails.
  • If your planks but up against trees or bushes, consider staining that side of the planks before installing them. Some sites recommend staining ALL of your boards before you install them but I’m not going that route.
  • Once everything is installed, let it sit for a week or two. The boards will dry out and shrink quite a bit. You should have installed the planks so they were tight against each other but after they dry, there will be 1/8-1/4” between them.
  • Stain! I won’t give any tips since I haven’t stained the fence yet, but my plan is to use a sprayer with a semi-transparent natural cedar color stain. I’ll have to rig up some tarps to avoid overspray in our tight quarters.

Yard Project Update 3

It’s hard to see a lot of change since the last update, but we’ve been working hard! The major accomplishments last week were installing French drains, installing downspout drains and getting the first part of the irrigation in the ground. That meant a LOT of trenching and some of it was through some incredibly compacted dirt. I took the day off Wednesday and spent a good portion of the day with a pick axe breaking through it. I was sore that night! It feels great to have this all in the ground and hidden away though. Our back yard should be significantly drier now. It had previously been a swamp any time it rained, but a majority of the water that falls on my property will now be piped away. And I’m very excited to have irrigation! Given the layout of the yard and the water lines, we actually started with the parts of the yard that need irrigation the least but that’s ok. We’ll get to the rest of it.

And I should also mention that Don came over three days last week to help me set fence posts. Thank you! We put cardboard tubes in behind the wall to hold back the rock and give us a place to set the posts. Those cardboard tubes started to fail a bit in the rains so Don helped me get them set. There are only three more posts to dig and set before I can start building most of the rest of the fence.

Our neighbors have been super nice during this project, and that’s a good thing since we feel a lot closer to them with this fence removed! They even asked Tim to come take a look at their back yard when he’s done. We had another neighbor stop by and ask for Tim’s card too. He does great work and people are noticing.

The next steps will be finishing the irrigation in the other half of the back yard, filling in all the trenches, setting those posts and then building the fence. The majority of the work is behind us but there’s still plenty to do.

Indiana Trip Recap

There have been a few posts that mentioned our trip to Indiana, but I haven’t talked about the overall trip yet. We went back over Memorial Day weekend so that Dad, Luke and I could attend the Indy 500. Tyla and I were unsure how Elijah would handle the flight, but he did really well. We got a direct flight into Midway and then Mom and Dad picked us up so that we’d only have one flight to get through. It wasn’t as easy as our trip at Christmas, but we couldn’t have asked for much more from a one year old who just wants to walk and crawl everywhere.

The weather was pretty nice so we spent quite a bit of time outside going on walks or just pushing Elijah around in a little car that belongs to his cousin David. That thing was a huge hit! Luke, Rachel and David were there for the weekend and Grandpa and Lynnette came for a day too. Since it’s rare to have everyone together, Mom organized a family photo.

It was a nice trip and a good vacation. We relaxed a lot, visited some fun places, and spent a lot of time with my family.

The Psychology Of Perfection

While very often I believe that “done is better than perfect”, trap shooting is not one of those times. Don, Logan and I headed to the range for the first time in about nine months. I generally hit around 18-20 out of 25 and my best round ever was 23. I thought I’d be pretty rusty, but on my first round I just kept hitting them. I was able to stay pretty calm until I got to the last position of 5 clays. 20 in a row. Wow. Just a few more. As I hit, one, two, three, and then four of them my nerves really started to take over. I had 24 in a row, already setting a personal best, and I was now one trigger pull away from the elusive perfect round. It’s not as difficult as bowling a 300, but it’s still pretty rare. You get a badge from the gun range and the envy of your fellow shooters. All those thoughts were swirling through my head. I tried to clear them out, take some deep breaths, focus on just one more shot like I had been doing all morning. I called “PULL!”, the clay flew out and I thought “Oh good, an easy one!” I moved the gun along the flight path pulled the trigger and… instantly knew it was wrong. I’m pretty sure I led it too much and the clay sailed to the ground unharmed. 24 out of 25. A great score, but it was obvious to everyone that I choked under the pressure.

As with many other sports, once you figure out the mechanics, trap shooting is mostly a mental activity. Can you stay focused? Can you keep your nerves in check? Can you get into the zone and let your body do it’s job? It’s a very interesting challenge because the only way I’ve found to get better is to train and be in that situation. Faking it works to some extent (pretending you have a prefect run even if you’ve already missed) but it’s not the same. The pressure is getting easier over time and that’s what keeps me going. I used to freak out when I was close to getting 20/25 and now I am almost blasé about it if I’ve already missed one.

Will I get to 25? I know I can do it, but I wouldn’t be surprised if it takes a few more great runs to get me there so I can conquer these nerves.

Weight Loss Data

Yesterday I wrote about the process of losing weight, but I only alluded to data sets. Let’s dig in! My data sources were the Fitbit API (for both number of steps and weight) and some weather history which I’ll explain later. This all came into through Power Query.

First of all, here is a chart showing my weight over time and then which days of the week. I usually gained weight on Sundays (our days to get together with family), Tuesdays (taco day in the café at work) and Fridays (the day we sometimes go out to eat.)

Next up are some charts showing the number of steps I took each day. The chart on the left shows how often I took a certain number of steps. The chart on the right shows the total number of steps each month. Note that we’re only halfway through June so that bar is shorter.

I fully expected to see a correlation between the number of steps I took on a given day and the amount of weight that I lost. Nope. Here’s a scatter plot showing no correlation. I think that walking is good for weight loss if you’re very overweight and you don’t move much. But there’s a point where walking is just too efficient to do much additional good.

I then started looking for other possible data correlation. Maybe the number of steps that I took was related to the temperature? Nope.

We’re in a wet part of the country so maybe the amount of rain we get in a day dictates how many steps I take? Not really. My really big days have happened when it doesn’t rain, but just because it’s dry doesn’t mean I’ll walk a lot.

In the end, I took all the various data points and ran them through Excels correlation algorithm. Nothing came out showing any real correlation. The biggest one was one of the charts you see above: the bigger the high temperature, the more steps I take, and even that was only a 0.48 correlation. That’s skewed quite a bit too because I’ve been doing a LOT more yard work lately and it has been warmer.

Even though I didn’t find a scientific way to lose weight, I did learn lots of things that AREN’T related and that’s interesting too!
