Earthquakes are such a challenge in engineering: unpredictable both in time and intensity. But I love this solution of base isolation because it’s so intuitive. It’s something my five-year-old would come up with: just put a suspension system on a building.

🚆Watch The Logistics of X: https://nebula.tv/thelogisticsofx?ref=practical-engineering

Errata:
3:47 Wind sock is in the wrong direction!
9:05 The graphic and voiceover could have explained this more clearly. Tire width goes into estimating pass-to-coverage ratio in pavement design to estimate load repetitions. For rigid pavements, it&apos;s measured at the surface. For flexible pavements, it&apos;s measured at the top of the subgrade. For rigid pavement, the fatigue concern is maximum tensile stress at the bottom of the PCC slab. That bottom stress is governed mainly by slab bending mechanics and load position. A small lateral shift can change the critical bottom stress a lot, so the “near-maximum response” region doesn’t expand the same way it does with a flexible pavement.

Some of the construction techniques and engineering requirements for runways that you don’t really notice when you’re a passenger looking through the window

Engineering is a balancing act; we need structures that are both strong and safe, but also affordable, easy to occupy, and maybe even architecturally pleasing. Using knowledge gained from tests like this helps us get a clearer definition of the edges of the problem we’re solving.

Huge thanks to Dr. Dan Cox and his team of researchers at Oregon State University for inviting us to film this test. Check them out here: https://engineering.oregonstate.edu/wave-lab

I don&apos;t have any good answers to any of this, but I think it&apos;s worth discussing nonetheless. My heart goes out to the victims and their families who were affected by this flood.

      <video:description>The saga of Auburn Dam and Foresthill Bridge

Auburn Dam left a lot of scars, both on the physical landscape and the political one. But it also left this bridge that became more than just an out-of-place oddity. In a sense, it’s become a monument to the end of an era in US major public works projects, and, hopefully, a tribute to the caution and care that will shape the next one.

The story of mine subsidence is the story of so many things in engineering - addressing the difficulties we used to just ignore. This is a real issue that causes real damages today, but it’s also an issue that a lot of people put a great deal of thought, effort, and ultimately resources into so that we can strike a balance between protection against damage to property and the environment and obtaining the resources that we all depend on.

There are enormous benefits to be had using nuclear materials in many areas of science, engineering, and medicine. But there are enormous costs as well, many of which we might not be aware of if we don’t make it a habit to read obscure government investigation reports.

      <video:title>This Bridge’s Bizarre Design Nearly Caused It To Collapse</video:title>
      <video:description>The wild story of Washington Bridge in Providence, Rhode Island.

@CaseyJones-Engineer coverage: https://www.youtube.com/playlist?list=PLZVX8Mc53RWce9eZHdDPj9FoMA_v0cmmP

Just like engineers design structures to be ductile, to fail with grace and warning, we want and need projects like this to happen in an orderly fashion. We should be able to recognize when replacement is necessary, plan ahead for the project, do a good job informing the public, and execute the job on a timeline that doesn’t require panic, chaos, and emergency contracts. The Washington Bridge is a perfect case study in why that’s so important.

      <video:description>Errata: At 14:14, the bridge shown is the Danube City Bridge in Vienna, not the Ed Hendler Bridge in Washington. Sorry for the mistake!

I don’t think there’s a better example in history where all the various factors of a technical problem converged into a singular solution in this way. I love cable-stayed bridges. Happy Valentine&apos;s Day!

      <video:description>Bridges for animals

Errata: Several people have pointed out crossings that are larger than the Wallis Annenberg bridge will be. I should have said &quot;largest of its kind,&quot; meaning true bridges.

The reasons we’re willing to invest so much into wildlife crossings aren’t as obvious as you might think, and there are some really interesting technical challenges when you’re designing infrastructure for animals.

      <video:description>Following the dollars from your bill through the grid

The grid is not only mechanically and electrically complicated; it’s financially complicated, too. We don’t really participate in all that complexity - we just pay our bill at the end of every month. But it does affect us in big ways, so I think it’s important at least to understand the basics.

      <video:title>1.5 Years of Heavy Construction in 1.5 Hours</video:title>
      <video:description>By popular request, we combined the Practical Construction series into a single video. This was originally released in 2023 in a series of 5 episodes as an experiment in long-duration, on-location production. It was a lot of work, but a ton of fun, and I&apos;m really proud of the result. I hope you enjoy it!

Huge thanks to our project partners!

There’s a lot changing in the construction industry, and a lot of growth in the need for materials like sand and gravel. But I don’t think it’s fair to say the world is running out of those materials. We’re just more aware of all the costs involved in procuring them, and hopefully taking more account for how they affect our future and the environment.

      <video:title>When Infrastructure Gets Hacked</video:title>
      <video:description>A few interesting stories about digital security for infrastructure

Digital systems interact with every aspect of our daily lives and basic needs: water, electricity, sanitation, public health, transportation, and more can all be seriously disrupted by someone or some group, anywhere in the world, if we let our guard down. With great computer power comes great computer responsibility. And just because many of these industrial control systems are only used or understood by a small number of people, security through obscurity just isn’t realistic anymore.

Of course, we have a lot of room for improvement in how we think about and manage solid waste in this world. Landfills seem like an environmental blight, but really, properly designed ones play a huge role in making sure waste products don’t end up in our soil or air or water.

      <video:description>The 1937 New London School Explosion

Correction: Tyler is west of New London, not east.

Natural gas is one of the most important resources on the planet right now. It’s driven countless innovations that benefit nearly everyone in a huge variety of ways. And so, even if you had never heard of New London, Texas before now, you can feel fairly confident that, all these decades later, you’ve also benefited in some way from the hard lessons learned there in 1937.

Thanks to Michael Wereschagin for sharing his expertise and research for this story. Check out his book on the New London School explosion here: https://wereschagin.com/about

      <video:title>This Bridge Should Have Been Closed Years Before It Collapsed</video:title>
      <video:description>Why Fern Hollow Bridge collapsed

This is a crazy case study of how common sense can fall through the cracks of strained budgets and rigid oversight from federal, state, and city staff. And the lessons that came out of it aren’t just relevant to people who work on bridges. It&apos;s a story of how numerous small mistakes by individuals can collectively lead to a tragedy.

      <video:description>See some cool bridges, learn some new words!

Errata: At 9:25, Edmonton is in Alberta, not Saskatchewan.

Without listing every bridge, there’s no true way to list every type of bridge. There’s too much nuance, creativity, and mixing and matching designs. But that’s part of the joy of paying attention to bridges. Once you understand the basics, you can start to puzzle out the more interesting details.

All of our lives benefit in some way from this enormous control over Earth’s freshwater resources. But those benefits come at a cost, and the price isn’t just the dollars we’ve spent on the infrastructure but also the impacts dams have on the environment. This kind of balancing act is really at the heart of what a lot of engineering is all about.

Welcome to my shop. Today we&apos;ll be designing and building nine different ball bearing launching catapults. Why? Other than being a lot of fun, the catapults are the perfect vehicle to show you all of my major tools, how they work, and why I have them. I had fun making these, I hope you enjoy them too.

Approximately 999,999,998 people have asked me to send my unpickable lock to the Lock Picking Lawyer. I decided to do you one better - I&apos;m sending the Lock Picking Lawyer TWO unpickable locks with different designs. It will be interesting to see if he can pick them, if so, we&apos;ll fix those issues to make them even stronger.

When I was offered the opportunity to beta test an upcoming robotic arm from Tormach, I knew exactly what I wanted to do with it. CNC chainsaws baybeeeeee. Aside from being fundamentally awesome, it is a very interesting software problem. Since I didn&apos;t have to build the arm I was able to focus the project and the video on the software challenges of making something like this work. Thank goodness I didn&apos;t have to build the arm because the software almost killed me. I can imagine all kinds of next steps for this creation like machining textures with the chainsaw or cutting topiaries. I hope you like it!

An automatic pool playing robot - how hard could it be? Turns out harder than I thought. It took me quite a while to work through all the difficulties of this project but when it all finally came together is so worth it. To my surprise the most interesting aspect of this project is using the cue to play real games of pool over the internet. Let me know if you think twitch plays billiards would be worthwhile...</video:description>

It was time to take another pass on the hair cutting robot. The new robot is bigger, better, way more reliable and travel friendly. I tried to cut MatPats hair (live) then my brothers hair and then my own. For some reason I&apos;m compelled to improve the pattern carving functionality even though I have zero desire to actually use it....

One final thing - if you know of any actual problems that could use a better solution please leave a comment. One of my goals is to make a portion of my projects attempts at solving legitimately useful problems and I would love to have a good list of them. Thanks!</video:description>

How hard could it be to make an unpickable lock? Turns out pretty flippin hard. After I recovering from the mental and physical turmoil of getting this thing made I called up a locksmith to see if they would be able to pick it. A fun time for all involved.</video:description>

I&apos;ve been wondering if I could turn my haircut robot into a pumpkin carving robot. Cutting hair and carving pumpkins isn&apos;t really that different if you think about it - both cut stuff off a roughly pumpkin sized spheroid. In this video I do just that and carve some pretty amazing pumpkins with it. This was a  bit of a sprint to get done - I can&apos;t wait until next year to make even more insane pumpkins with it!

The previous explosive bat was cool, but it wasn&apos;t setting any records. I set out to design a bat that could beat Babe Ruth&apos;s home run record of 575 feet. The engineering was intense but the results are spectacular. Aside from attempts on the record, you can also look forward to some awesome high speed footage of the bat in action and a special guest.

This video could not have been made without the help of Destin from Smarter Every Day. Not only did he provide the high speed camera, he also shared all his footage from testing the bat. He made a more in depth video on what happens when this this bat goes boom. Check it out!

Thousands have told me that anyone can easily miss my first automatic basketball hoop by missing the hoop entirely. That is a really good point and something that I can&apos;t let stand. In this video I show you how I devoted several weeks of my life to realizing a basketball hoop that makes your shot go in even if you totally miss the hoop.... it was a lot of fun, and quite a bit more challenging than I was anticipating. Hopefully you enjoy it :)

Although very fun, these videos are very time consuming and expensive. Please consider helping to support the development of these projects through my patreon at http://patreon.com/stuffmadehere

This project was really hard. It was a huge challenge to whittle the 450gigs of footage down into a video that shared my journey of designing and getting this machine working. I hope you enjoyed it :) If you are interested in helping to support me making more of these videos you can check out my Patreon at http://patreon.com/stuffmadehere. One question - would a podcast be interesting yes / no? I&apos;ve been considering that as an opportunity to share more details and whatnot that can&apos;t make it into my videos.</video:description>

I made a baseball bat that (pretty much) always hits home runs. It uses explosive charges to put an enormous amount of power into your swing. In this video I show how I designed it and all the unexpected trials and tribulations of getting something like this to work. It turned out to be really hard but the end result is so much fun I can&apos;t complain. I don&apos;t think it&apos;s possible to use this bat and not grin.

The possibilities for this kind machine are endless with the most interesting things being haircuts that are too hard for human hair cutters to achieve. Imagine a mathematically perfect fade from one side of your head to another. Or imagine if I added a trimmer to this and cutting perfect lithopane pattern into your hair.  I consider this the first generation machine and hope to build another to explore some of the crazier haircut concepts.  A colleague suggested adding a precision hair dying attachment and doing some crazy multi-color hair styles. I wouldn&apos;t say that&apos;s really &quot;my jam&quot; but I might try it in the name of science &amp; engineering. 

This isn&apos;t just limited to humans either. Imagine sticking a poodle in this or making a bigger one to create topiaries. Lots of fun ideas....

I got nerd sniped by a great comment in a previous video. The idea was to make some kind of device to let blind people perceive their surroundings. The specific suggestion was to make some kind of a vest. Ultimately I ended up making an iPad case that uses the sensors in the iPad to perceive the surroundings and communicates through tactile feedback via a special hand grip. It was a fun project and turned out pretty neat.

I wanted to see if I could make myself a better golfer by combining robotic engineering and golf. The result is a robotic club that senses your swing and corrects your shot for distance. It should be possible to correct for slice and hook with some hardware and software upgrades. It also has a cool mode where it can be any iron so no need to carry eleven clubs.

All hail our our robot overlords. I&apos;m looking forward to gen 2 and doing more science on how good a robot really can make you.

I wasn&apos;t totally satisfied with my previous basketball hoop so I made another try at the problem. This time with robots and computer vision! I designed and build this hoop from the ground up with the goal of tracking the ball and directing it into the hoop by tilting the backboard. It works pretty well. My old solid state hoop is old news. Long live our robot overlords. 

I wonder what V3 will look like...

I&apos;ve wondered if it is possible to make a basketball hoop where the ball always goes in. Imagine throwing a ball and if it hits the backboard it somehow gets directed into the hoop. Thanks to physics it isn&apos;t quite possible to make ALL possible shots go in though you can make a hoop where the ball goes in a lot more often. In this video I show how I wrote a program to calculate the optical backboard then machined and fabricated it. It worked out better than I was expected so I&apos;m really happy with it!

I recently acquired a Tormach 1100mx. I&apos;ve started to outgrow my existing mills and have been looking for a VMC that was feature rich but that I could also get into my basement. I show the rigging process of getting it into my basement, assembly, and then machining a tool holder for it. Also includes some 3D printing and plasma cutting. Finally I take the tool breakage detection and rigid tapping features for a test drive.

Several years ago I built a CNC machine. It&apos;s been having some flood coolant system issues so I decided to cut out the heart of the coolant system and build it stronger. In this video I show how I did that.

In this video I show more techniques for 3D printed sheet metal press forming tools. I improve over my previous designs by making a tool with a moving action as well as fixing a major design flaw. I also demonstrate a more complicated forming operation with many features made in one pressing.

Plasma cutting is incredibly useful. Paired with bending and welding it is often the fastest and cheapest way to build any kind of mechanical structure or enclosure. Results that might take a day on a 3D printer or on a CNC mill can be achieved in minutes on a plasma cutter. Not to mention the cost of sheet metal is a lot cheaper than 3D printer materials or billet for machining. I&apos;m constantly making folded and welded structures with my plasma cutter and every time I have the same problem. I will design a complicated folded part and then when I go to bend it I can&apos;t place the bends accurately. I&apos;ll spend a lot of time trying to measure them out but the plasma cutter can make any arbitrary shape which can make measuring difficult. 

To solve this problem I designed and built a pen plotter head for my plasma cutter. It allows me to first draw all of the bend lines then cut out the part. This gives me perfectly registered bend locations that make folding the parts really easy. 

This video details how I designed it and how it works.

When I was designing the downdraft for my plasma cutter I was concerned that it might eject too much metal dust out of my shop and into my driveway. It turns out that I was right and as I&apos;ve been cutting more I&apos;ve noticed a real uptick in accumulated metal on the ground. To address this problem I built a filtering system designed to remove the bigger particles from the exhaust. Since I&apos;m not concerned with smoke and really extremely fine vapor I was able to make a &quot;solid state&quot; filter that takes advantage of the inability of a heavy particle to follow a tight corner. It was inspired by cyclonic seperators on larger shop vacuum systems. From the testing that I&apos;ve done it seems to work quite well and I&apos;m pretty happy with the results.

      <video:title>Bending Steel With Plastic Tools</video:title>
      <video:description>I&apos;ve been wondering if 3D printed tools could possibly bend steel. It seemed possible unlikely. I designed and printed several tools which are used on a hydraulic press to bend and form steel sheet metal. This particular tool could be made by CNC machining the tools from metal but 3D printing it is much faster and easier.
