Wooden Puzzle Book Will Twist and Dazzle Your Brain

Posted on by

In what might be one of the coolest applications of laser cutting, joinery, puzzles, writing, and bookbinding, [Brady Whitney] has created the Codex Silenda — a literal puzzle book of magnificent proportions.

[Whitney] had originally conceived the idea of the Codex for his senior thesis research project at Iowa State University, and the result is something for almost everyone. On each of the Codex’s five pages lies a mechanical puzzle that must be solved to progress to the next, while an accompanying text weaves a story as you do so. These intricate pages were designed in SolidWorks and painstakingly assembled …read more

Complex, Beautiful Device is Limited to Text-speak and Cat Pictures (WTF, LOL)

Posted on by

Beautifully documented, modular, and completely open-source, this split flap display project by [JON-A-TRON] uses 3D printing, laser cutting and engraving, and parts anyone can find online to make a device that looks as sharp as it is brilliantly designed. Also, it appears to be a commentary on our modern culture since this beautifully engineered, highly complex device is limited to communicating via three-letter combos and cat pictures (or cat video, if you hold the button down!) As [JON-A-TRON] puts it, “Why use high-resolution, multi-functional devices when you can get back to your industrial revolution roots?” Video is embedded below. …read more

R/C Hot Rod Built Completely From Scratch

Posted on by

[ossum]’s R/C hot rod shows what’s possible when a talented hacker takes full advantage of all the modern resources available to them. The results are stunning.

[ossum] had a stack of Amazon and Shapeways credits lying around after winning a few competitions. He had this dream of building an R/C car for a while, and decided now was the time. After ordering all the needed parts from Amazon, he made an extremely nice model of the car in Fusion 360. The CAD model is a great learning resource. If you want to learn how to use reference photos, parts, and …read more

Hackaday Prize Entry: Invisible

Posted on by

[Kate Reed] found a quote by a homeless that said “No one sees us”, which led her to exploring what it actually means to be invisible — and if we actually choose to be invisible by hiding away our emotions, sexual preference, race or income. She realized that too often, we choose to only see what we want to see, rendering all the rest invisible by looking away. Her public art campaign and Hackaday Prize entry “Invisible” aims to increase social awareness and strengthening the community by making hidden thoughts, feelings and needs visible.

Inspired by the artist [Jin Young …read more

Low Cost Optics Bench Project – Now with Lasercut Optics

Posted on by

[PWalsh] has a clever idea for learning and experimenting with basic optics: instead of using actual lenses, he’s using clear pieces of laser-cut acrylic cut into lens profiles instead. They are much easier to make, mount, adjust, and handle while still bending light in the same basic ways. It allows for simple hands-on experimentation with plenty of visual feedback – perfect for beginners.

This idea is part of [PWalsh]’s low-cost optics bench project, which uses laser-cut plastic to create adjustable optics bench components. We’ve covered this project before, but [PWalsh] expanded the idea with the concept of these simple laser-cut …read more

Simple Robot Arm With Steppers Has Pleasingly Smooth Motion

Posted on by

The usual go-to when building a simple robot arm is the ever-pervasive hobby servo. However, these devices are not precise, and are typically jerky and unreliable. They have their advantages, but if strength is not needed a stepper motor would provide much better motion in the same price range.

Those are the lines along which [Bajdi] was thinking when he forked the Mearm project, and adapted it for small stepper motors. First he tried printing out the servo version on thingiverse. It worked, but the parts were not ideal for 3D printing, and he didn’t like the movement.

So he …read more
