Building a dedicated 3D printer hot end controller with the Arduino UNO R4 WiFi
Reading Time: 2 minutes3D printers need to set their hot ends to a very specific temperatures suited to the filament material and keep them at those temperatures throughout the printing process. Most use PID (Proportional-Integral-Derivative) control for that purpose, which modulates power according to an algorithm that prioritizes stability and prevents feedback oscillations. But what…

Small PoV display uses CD drive motor for high-speed rotation
Reading Time: 2 minutesThe human brain and eyes are imperfect, so your visual perception has a limited “frame rate.” That is somewhere between 30 and 60 frames per second (fps). Most films are 24fps, which is part of the reason they don’t quite look like real life. Once you reach the upper limits of the human visual…

Channel your inner Bruce Lee with this DIY reflex coach
Reading Time: 2 minutesVideo games are popular because they provide a clear and reliable loop of effort and reward. If you smash the baddie, you get experience; get enough experience and you level up. But real life isn’t like that and there is little direct correlation between effort and reward, which is dissatisfying. Gamification techniques…

MiuraKit simplifies pneumatic robot design
Reading Time: 2 minutesSoft robotics is a challenging field, because it comes with all of the difficulties associated with conventional robotics and adds in the complexity of designing non-rigid bodies. That isn’t a trivial thing, as most CAD software doesn’t have the ability to simulate the flexibility of the material. You also have to understand how the…

This timer uses a rolling ball to count the seconds
Reading Time: 2 minutesBefore we had fancy digital clocks — or even spring-driven mechanical clocks — most methods for measuring short periods of time relied on gravity moving something in a consistent, repeatable way. Both water clocks and hour glasses work under that principle. But it isn’t very fun to watch grains of sand fall,…
