A shift register is all you need to build an Arduino Nano-based retro computer
Reading Time: 2 minutesIf you’ve ever tried to produce an analog video signal with an Arduino, then you know that it isn’t easy. That’s a bit counterintuitive if you think of analog video as “old” and assume that generating an analog video signal would be trivial with our powerful modern hardware. But there are many…

A three-year journey to build a reaction wheel
Reading Time: 2 minutesHow do unstable things stay upright? True passive balancing is very difficult and isn’t dynamic, so it doesn’t help when there is movement. Active balancing is all about inertia and this is how a tightrope walker can traverse a chasm by making small adjustments with a long pole. This is the same…

Don’t ignore single-axis joysticks
Reading Time: 2 minutesWhen you hear the word “joystick,” you probably think of the standard dual-axis joysticks that we see on video game controllers. As the name implies, those move and provide signals for two axes (X and Y). But there is no reason that a joystick needs two axes and, in fact, that may…

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. A ceiling fan’s bearing needs to allow for smooth rotational motion with as little friction as possible, while completely constraining movement in every other axis.…
