Thank you Johnvk for sharing your age and ambition. I get very frustrated with people who think they are too old to learn anything and have no curiosity. These are usually people who think they learned everything they possibly could by the time they got out of high school. They seem to be convinced it is not possible to attempt new things.I have been on a crusade to help people become more curious and encourage them to acquire new knowledge and to attempt new skills. You, sir, are an encouragement to me.

Fantastic! I've enjoyed these printable fabric ideas you've been doing.

I had planned to do one of these in the spring this year. Now it is the end of summer. Does it really matter what time of year you start? It seems like if there stuff is still growing then it should be fine, but I was concerned that if I start at the end of the growing cycle then it may be too late for this year. What do you think?

Oooh, that sounds great. You want to design it for us? Would be fun to print and fly alongside this one.

Well, that didn't last long. Maiden flight broke it up pretty badly. Ha!Good thing I have a 4'X8' sheet of foam board.

Actually nothing in the radio changes. You are building a transmitter to send the signal to an AM radio station.

This simply sends out an AM signal. As long as your car radio can receive AM, doing this project is fairly simple. There is no modification to the radio at all.

Arduino's with the robot screen printed onto them.

A great solution to a real problem. Fortunately our kids both learned quickly how to read an analog clock. They didn't know what the numbers meant, but they understood the picture that 6:00 made with the big and little hands. However, I think this is something I will have to keep in mind when wanting to do a simple light system in the future.

Thank you. This helps me add a USB joystick/button controller for a RetroPie installation.

I will see if she will let me post a picture of her and the dress.You do know that when we got married pictures were taken on thin plastic and printed on special paper? We didn't have digital cameras back then. I would have to find and scan a picture from the big day.

We weren't makers back then like we are now. I would have been much more involved in the building stuff for the wedding if we were getting married today. Maybe for our 50th anniversary we will make Arduino controlled laser lights.

This is fantastic! I loved seeing the process and reading about the reason you made the choices you did. My wife can attest that I'm pretty terrible at sewing (she is amazing at it), but I love to see how things are made. You documented your process very well.My mother-in-law and wife made the dress that my bride wore on our wedding day. (They did let me help do a few small items so I could say I had a hand in it). After 24 years of marriage I fondly look back at those months leading up to the wedding and remembering the excitement we shared getting ready for the big day.I wish you well in your continued sewing adventures (please share them with us), and in your marriage.

The PLA would be fine with the condensation. It will not absorb any moisture. The wood on the other hand might. Colors probably won't fade in the usability lifetime of the coasters unless stored outside in direct sunlight.The only real problem is that because these are hard plastic then they will be slippery when wet. Because it is a raised QR code the water will pool underneath and may not be so bad.

A bit of hot glue in any place that you think might be exposed to shorting with the shot is a good way to insulate things.

As always, a great project from you. I love your videos and projects. I rarely do your projects exactly, but you give such great ideas of what can be done. I find myself going back to them again and again when something comes up that I want to try.

I have always been told no, but that doesn't mean you can't try it. The reason the Pi/Linux is not the best choice is that they don't work in "real time." The Pi and the operating system can do many things at once. Therefore, it doesn't complete instructions sequentially without interruption from other operations. This causes problems for precision on your X and Y axis motors. In theory you can make it work, but it probably won't be accurate. Don't let that stop you from trying.

This is a great project for a class. Easy in conception but made up of more than just a couple of parts. I love the video at the end! Parts crashing. The sound is fantastic.

I would think of it like a bicycle. No, it is not safe until you learn to ride it. But once you do it can be as safe or as dangerous as the rider makes it.

Amazing project. Congratulations on having such a nice looking project in the end.People are asking about the cost. I think this is one of those projects you do not because it costs less than buying one, but because it is a way to learn how each one of these systems work and gives you the skills to build bigger, better and newer projects. This looks like it was done by a group of university students. As a class project this is great.

I recently fixed an Arduino Mega because of a blown voltage regulator (a few months ago). Thanks for putting up such a clear Instructable and video for others who may find themselves in the same situation. I hate seeing good stuff thrown away because people don't take the time to figure out what might be wrong.Great job.

I'm not inclined to do this project, but it gives some great ideas on how to work with servos and programming logic. I wasn't familiar with XOD before, but I will check it out now. Thanks!

Very well documented and understandable. Thanks. This gives me ideas for how to extend a project that I built a couple of years ago involving a Raspberry Pi and a clock that is WiFi controlled so that I can tell the lecturer when his time is up.

This was great. Thanks for writing it. I had my first attempt at DuPont cable crimping a couple of months ago. Eventually I got it to work well and I actually enjoy creating wires of just the right length. This guide would have helped back then. I am sure it will be a help to others in the future.

I was in a gas station yesterday that had a case of spinners they were trying to sell for $1 each. I wonder how long it will take to get rid of them? I thought about buying a bunch just so I could have the bearings.

Coat something with a protective material. Never heard of it either, but Google helped me out.

You may want to jump over to the comments at Raspberry Pi .org and introduce yourself. They did a nice write-up on their blog about your project. https://www.raspberrypi.org/blog/storm-glass/

That looks wonderful! Makes a huge difference. I'm glad it worked well for you.

Even if you splice the wires, this would be an upgrade that doesn't cost much but adds value to the car when you sell it.

Thanks for the info on the wire harness adapter. I never even thought that something like that would be available. Certainly easier than fabricating something from paper clips.For the strip lights on eBay I would look for something like this: 12V led strip white.For less than $10 (US) you can get 5 meters worth of lights.

I attribute the build to being able to get a Fresnel lens out of your neighbor's junk pile last week. :-)

Thanks for your input nanosec12. I will have to check into the idea that my power supply was getting overloaded. Thanks for the comment.

Thank you Swansong. It was a fun build.

The ones he links to in the materials list are 4000-4500K. I assume that is what he is using.
