Trains are great for hauling massive amounts of cargo from point A to point B, and occasionally, point C on weekends. But they’re not really known for climbing hills well, and anything vertical is right out. Regardless, [Can Altineller] knows what he wants and set to work, creating the 3D Printed Wall Train.
The first step was to get the train to stick to a vertical surface. This was achieved with the use of neodymium magnets in the train, which are attracted to laser-cut steel plates beneath the plastic tracks. The train itself consists of a custom 3D printed locomotive, outfitted with a motor and step-down gears that drive all four wheels. Said wheels are of a conical shape, and covered with rubber to provide enough grip to overcome gravity. The project is a progression from [Cal]’s earlier four-motor build.
The final result is a charming wall display, with the four-wheel drive train merrily tugging its carriages around the circular course ad infinitum. It’s a fun build, and we’d love to see similar techniques applied to a bigger layout. If this whets your appetite for model railroading, consider building your own turntable, or implementing some fancy sensors. Video after the break.

As you might expect from one of our most illustrious alumni, [Caleb Kraft] is a rather creative fellow. Over the years he’s created some absolutely phenomenal projects using CNC routers, 3D printers, laser cutters, and all the other cool toys the modern hacker has access to. But for his latest project, a celebration of the full Moon, he challenged himself to go low-tech. The Moon is something that anyone on Earth can look up and enjoy, so it seemed only fitting that this project should be as accessible to others as possible.
[Caleb] started this project by looking for high-resolution images of the Moon, which was easy enough. He was even able to find sign shops that were more than happy to print a giant version for him. Unfortunately, the prices he was quoted were equally gargantuan. To really be something that anyone could do, this project needed to not only be easy, but as affordable as possible. But where do you get a giant picture of the Moon for cheap?
He eventually found a source for Moon shower curtains (we told you he was creative), which fit the bill perfectly. [Caleb] says they aren’t nearly as detailed as the original images he found, but unless you’ve got your face pressed up against it you’ll never notice anyway. To make the round frame, he used PEX tubing from the hardware store and simply stapled the curtain directly to the soft plastic. The hardest part of the whole project is arguably getting the curtain flat and taut on the PEX ring.
Technically you could stop now and have a pretty slick piece of art to hang on your wall, but [Caleb] took the idea a bit farther and put a strip of RGB LEDs along the inside of the ring. The shower curtain material does a decent enough job of diffusing the light of the LEDs to make it look pretty good, though there’s certainly some room for improvement if you want to get a more even effect over the entire surface. While you’re at it, you might as well add in some additional electronics so the lighting matches the current phase of the real-life Moon.
On the other hand, if you’re willing to settle for a far more diminutive version of Luna and don’t mind using those highfalutin hacker tools that [Caleb] decided to avoid for the good of mankind, we’ve got a project you might be interested in.

Few things hit a hacker or maker harder than when a beloved tool goes to that Big Toolbox In The Sky. It can be hard to trash something that’s been with you through countless repairs and teardowns, made all the worse by the fact most employers don’t recognize “Tool Bereavement” as a valid reason to request time off. Maybe next time one of your trusty pieces of gear gives up the ghost, you can follow the example set by [usuallyplesent] and turn it into a piece of art to hang up on the shop wall.
The shop had gotten years of daily service out of this air powered angle die grinder (not bad for a $14 Harbor Freight tool), and he thought they should immortalize it in their waiting room by turning it into an interesting piece of art. After all, it’s not everyday that some folks see the insides of the sort of tools the more mechanically inclined of us may take for granted.
After taking the grinder apart and cleaning everything up, [usuallyplesent] decided to simplify things a bit by tossing out the assorted tiny components like seals and washers. By just focusing on the larger core components, the exploded view is cleaner and reminds us of a light saber cutaway.
Using a piece of scrap cardboard, [usuallyplesent] made templates for all of the major pieces of the grinder and used that to sketch out the placement and spacing on the white background. He then cut out each shape so the parts would be partially recessed into the board. This gives the effect that each piece was cut down the middle lengthwise but without all the hassle of actually cutting everything down the middle lengthwise.
We’ve previously seen similar displays made out of dissected consumer electronics, but there’s something rather personal about doing the same thing for a well-used tool. If any of our beloved readers feel inspired to enshrine a dead multimeter into a shadow box over the bench, be sure to let us know.
We love seeing how things work. Exploded views are like mechanical eye-candy to most engineers, so when [Chris’] Kindle Touch died, he decided to give it new life… on his wall.
Inspired by others, he decided to mount all the components of his Kindle onto a piece of plastic that he could hang up on his wall. As an electronics design engineer, he’s always looking for new ideas and ways to design and build circuits — what better way to inspire creativity than to see a real product blown apart? Does anyone remember reading [Stephen Biesty’s] Incredible Cross Sections or Incredible Explosions as a child?
The construction is quite simple, relying on mounting holes where possible to screw parts directly to the board, or by using heavy duty double-sided tape. After finishing the Kindle, [Chris] found an old iPod of his and decided to give it the same ritual.
