We don’t really know what to say. This Skeeball cabinet is built entirely from Knex. It works exactly how you’d expect Skeeball to work. You plug in quarter and it dispenses balls and keeps score. [Shadowman39] worked on the build for more than a year. Everything that went into it is a Knex part with [...]

[Alex] was tasked with a control design problem for a set of motors. The application called for the back of a truck to open up, some 3D scanning equipment to rise from its enclosure, and finally the equipment needed to rotate into place. All of this needed to happen with one flip of a switch, [...]

Twitter can be a great tool for keeping up to date with your favorite person/company/band/etc. You can find a Twitter client for just about anything that plugs in these days, but sometimes we find that we simply need a break from our computers and smart phones – even if just for a few minutes. What [...]

For several years, [Jim] has wanted to construct a fully-mechanical universal Turing machine. Without the help of any electronic circuits or electrical input, his goal was to build the machine using simple hand tools and scrap materials. If you are not familiar with the concept of a Turing machine, they are devices that manipulate symbols [...]

So you’re master of electrons; able to program multiple chip architectures without batting an eye. Good for you. The only problem is that blinking LEDs gets boring after a while and you’re going to want to do something else. Here’s a chance to expand on your physical construction skills. Make: Skill Set is sharing the [...]

As a proof of concept for his long term work in progress “The Pac-Machina” (an electro-mechanical reimagining of a Pac-Man cabinet), [Jonathan] needed some way to make a mechanical Pac-Man, flappy jaw and all. After working through a couple different design possibilities, he decided on an interesting setup which includes using a cog with only [...]

While this mechanical mustache isn’t made for a Halloween costume, it certainly looks like part of one. Copper clad, brass, cable, and a few other bits come together in a similar style to tension based hands; the piece is then worn much like a Mardi Gras mask. To complete the rustic “old tyme” look [John] [...]

This project explores the early days of television. Above you see a view from the back side of a mechanically scanning television. The black disk spins and the holes, aligned in a spiral pattern, create vertical scan lines for projected light to shine through. In this case, [Eckhard Etzold] is using red, green, and blue [...]
