Ceiling fan becomes a “spaceship” SCARA robot arm
Reading Time: 2 minutesWe all know how annoying a ceiling fan can be when it isn’t balanced well and that annoyance perfectly demonstrates the necessity of a good, sturdy bearing.

Autochef-9000 can cook an entire breakfast automatically
Reading Time: 2 minutesFans off Wallace and Gromit will all remember two things about the franchise: the sort of creepy — but mostly delightful — stop-motion animation and Wallace’s Rube Goldberg-esque inventions. YouTuber Gregulations was inspired by Wallace’s Autochef breakfast-cooking contraption and decided to build his own robot to prepare morning meals. Gregulations wanted his Autochef-9000 to…

This new game engine runs Manic Miner on an Arduino UNO
Reading Time: 2 minutesFor owners of Sinclair ZX Spectrum computers in the ‘80s, few games were more desirable than Matthew Smith’s Manic Miner. It is very much a classic and has official and unofficial ports available for just about every console and computer released since. There was even a port made for Microsoft’s Zune MP3…

Getting more realistic camera movements in VR with an Arduino
Reading Time: 2 minutesIn virtual reality, anything is possible, yet being able to accurately model things from the real-world in a digital space remains a huge challenge due to the lack of weight/feedback that would otherwise be present in physical objects. Inspired by working with digital cameras and the inherit imperfection they bring to their…

The Hardware-Oriented Microprocessor Simulator illustrates the inner workings of microcontrollers
Reading Time: 2 minutesDo you really understand what is happening within the mysterious black packaging of a microcontroller or microprocessor? Most people don’t — we just learn how to use them. That’s because they’re wildly complex circuits combining many different subsystems that are all abstracted away from the view of the user. To help students better understand…

Build a better spindle controller for your CNC mill
Reading Time: 2 minutesProper spindle speed control is necessary to get good CNC milling results. If your spindle speed is inconsistent, your speed and feed calculations will be wrong. That will lead to poor finishes and even broken end mills (and ruined parts) in extreme cases. But cheap CNC mills and routers often have insufficient…

Tabletop device teaches you the basics of sailing before hopping on board a real boat
Reading Time: 2 minutesSailing is a great way to get outdoors and explore the open waters, yet it can also pose some risks to the pilot and passengers if they are unfamiliar with how the boat handles under different wind conditions. As Kif Scheuer notes in his project write-up, traditional instruction relies on simple 2D illustrations,…

Affordable fixed-belt CNC plotter runs on Arduino
Reading Time: 2 minutesDesign paradigms are the norm in every industry and automated machine tools aren’t any different. Most 3D printers, for example, function in a similar way: each axis rides on rails, with belts pulled by fixed motors. Pen plotters tend to utilize similar kinematics. But sometimes we see builds that ignore established paradigms,…

This automated machine shuffles and deals cards so you don’t have to
Reading Time: 2 minutesShuffling and dealing is very serious business when you’re playing any card game that puts money on the line, like poker. Even when the stakes aren’t that high, poor shuffling or dealing can drive a family apart. If you’re tired of being criticized for your card-handling skills, maybe you should build this…

Transform your coffee table into a piece of kinetic sand art
Reading Time: 2 minutesLike most furniture, a coffee table should both look good and function well. To function well, a coffee table just needs a flat surface. But looking good is a lot more complicated and depends entirely on owner taste. If kinetic art is your thing, then you might consider building this automatic sand…

Desktop elevator provides a positive sensory experience for an autistic child
Reading Time: 2 minutesAutism often comes with a unique sensory experience that differs from that of most neurotypical people.
