LED Hour Glass: In this article I describe how we made an hour glass with leds as the sand. We were always interested in making something that visually flows like sand and decided to use an hour glass to start. The movement is not completely fluid given the…

Laser cutters require quite a lot of power and laser tubes need active water cooling, which means you need a coolant reservoir and a water pump. You also need an exhaust fan to remove smoke, which will reduce the laser's efficacy. Add in a computer, positioning…

One of virtual reality’s largest unsolved challenges is allowing players to interact with a virtual environment beyond just video and audio. This is why a team of researchers from National Chengchi University in Taiwan came up with the FingerX project as…

Before the advent of digital cameras, people used film to capture their most cherished memories. And nowadays, there is a rush to convert them into a digital format before they inevitably degrade and become unrecognizable. Film slides in particular have a…

Virtual reality technology is advancing quickly and today’s headsets provide a very immersive visual and auditory experience. But they neglect the other senses. Haptic feedback, via vibration motors in controllers, is the only common technique for imparting…

Back in August 2021, mechatronics engineer ‘engineer2you’ had the idea to create a fun CNC plotter that easily mounts to a pair of points along a wall and traverses across the surface to draw on it, essentially becoming a self-contained mural-making robot. The…

Omni wheels, sometimes referred to by the trademarked Mecanum name, are special wheels lined with rollers. Thanks to the orientation of the rollers, a vehicle equipped with four omni wheels (each driven independently) can move in any direction by vectoring…

The aphorism that “they don’t build them like they used to” is especially true of the consumer electronics industry. Most manufacturers today design their product to last only a few years — or with outright planned obsolescence. But mid-century stereo consoles…

Nipkow displays are a special kind of persistence-of-vision device in that they use a spiral of tiny cutouts on a large spinning disk along with a single point of color generation to make an image. Maker Mac70 has come up with his own 3D-printed version,…

When trying to imagine a new way of interacting with either a video game or even another person remotely, being able to feel both temperature and touch sensations isn’t what most people would have in mind. However, thanks to some very interesting research…

Stephen Gidge and his roommate have a poorly-lit flight of stairs in their home. That isn't a big deal during the day, but it is a recipe for late night tumbles. They could have setup some nightlights or installed a new hall light, but they were both experienced…

Omni wheels are fantastic because they let a vehicle drive forward, backward, left, right, and rotate — all without a steering mechanism. There are only two catches: all four omni wheels must be driven and omni wheels don’t handle rough terrain or obstacles…

In theory, a Pirani gauge is a very simple device for measuring the pressure of a gas within a container, as it consists of a heated metal wire that loses heat as the pressure increases internally. With this value now known, the electrical resistance can…

Back in early 2020, Samsung demonstrated their Ballie robot concept at CES, and although it never got off the ground, it inspired Derek Lieber to create his own version of a gyroscopically stabilized robot that moves with a pair of hemispherical “wheels”…
