Settlers of Catan is a staple for boardgaming aficionados. Some fans like to express themselves by building a custom set of their own, and [Maclsk] is no different. Enter 3D Catan! The models for the various pieces were designed in Blender, a great open source 3D modelling program. They were then printed on an Anycubic i3 […]
The only thing limiting the range on any electric vehicle isn’t really battery technology, but cost. Customers don’t want to pay more money for an electric car or van that does essentially the same thing as one with an internal combustion engine. This in turn limits the amount of batteries manufacturers put in their cars. […]
3D printed lithophanes are great, if a bit monochromatic. [Thomas Brooks] (with help from [Jason Prius]) changed all that with a tool for creating color lithophanes but there’s a catch: you’ll need a printer capable of creating multi-color prints to do it. A video (embedded below) begins with an intro but walks through the entire process […]
I find that if I’m trying to make a point with a student or a colleague about a circuit, sometimes the Falstad online simulator is worth a few thousand words. You can draw the circuit, play with the values, and even see the current flow in an intuitive way as well as make traditional measurements. […]
Are your aluminum extrusions too straight? The Crimson Axlef*cker can help you out. It’s a remarkable 3D printed, 4-stage, 125:1 reduction gearbox driven by a brushless motor. Designer [jlittle988] decided to test an early prototype to destruction and while he was expecting something to break, he didn’t expect it to twist the 2020 aluminum extrusion […]
On August 8th, an experimental nuclear device exploded at a military test facility in Nyonoksa, Russia. Thirty kilometers away, radiation levels in the city of Severodvinsk reportedly peaked at twenty times normal levels for the span of a few hours. Rumors began circulating about the severity of the event, and conflicting reports regarding forced evacuations […]
The Coanda effect is an aerodynamic principle regarding the way fluids tend to flow along curved surfaces. This can be used to direct a flow, and [Tom Stanton] wanted to try out its application on a quadcopter. (Video embedded below.) The project began by firing up the 3D printer, which made experimenting with a variety […]
Planning a game of Hacker Jeopardy at your next meetup? You’re going to want some proper buzzers to complete the experience, but why buy when you can build? [Flute Systems] has released an open source DIY game buzzer system based on the Arduino that will help instantly elevate your game. Certainly beats just yelling across […]
You’d think that something made out of glass and epoxy would transmit a decent amount of light. Unfortunately for [Jeremy Ruhland], it turns out that FR4 is not great light pipe material, at least in one dimension. The backstory on this has to do with #badgelife, where it has become popular to reverse mount SMD […]
Product recalls are one of those things that most people don’t pay attention to until things get really bad. If it’s serious enough for somebody to get hurt or even die, then the media will pick it up, but most of the time they simply pass by in silence. In fact, there’s a decent chance that […]
