A circular saw is a must-have tool for anyone who wants to do even basic woodworking. But getting clean, straight cuts is a skill that takes practice to develop. To automate the process in order to perform clean cuts every time with zero effort, Red Tie Projects created this self-guided circular saw. This is exactly […]
These days, everyone seems to turn to robots for automating tasks in the physical world. But robots are often clumsy and unreliable — not to mention expensive. Trains, on the other hand, are famous for their reliability. With that in mind, YouTuber James Whomsley designed a model train railway to bring coffee from his kitchen […]
AI-generated art is all the rage right now, thanks to widespread sharing on social media. The appeal is obvious: anyone can utilize an online service to create a unique (and often hilarious) piece of art based on a simple prompt. To display that art, one can utilize a high-quality printer or a digital photo frame. […]
Sometimes you get a hankering for a snack, but there is no snack within arm’s reach. Such a situation is a tragedy and exactly what we built society and technology to avoid. To prevent this frankly appalling possibility, Michael Rigsby made Snacky, which is a snack-dispensing system that lets Amazon Astro robots deliver snacks to […]
There are three types of motors that makers typically consider: stepper motors, servo motors, and DC motors (either brushed or brushless). Stepper motors are great when you need high precision and torque, but tend to have jerky movement. DC motors work well for high speed movement that doesn’t need any rotational accuracy. Servo motors are […]
While we adults don’t experience them often, school kids practice fire drills on a regular basis. Those drills are important for safety, but kids don’t take them seriously. At most, they see the drills as a way to get a break from their lessons for a short time. But what if they could actually see […]
Biometric identification and authentication is big business. As an example, consider Apple’s Face ID technology, which has made strong smartphone security both user friendly and readily available. But Face ID requires substantial hardware and computational power to work, which makes it ill-suited for applications where cost is a major concern. To fill that gap in […]
If you frequent driving ranges, you’ve probably seen a machine (often attached to the front of an armored golf cart) designed to pick up golf balls. Because a driving range can easily fill up with thousands of golf balls an hour, such machines are necessary. After noticing that nobody wanted to pick up the ping […]
Take a moment to think about some of your favorite electronic music DJs. How many of them wear some sort of a helmet or mask? You can probably think of at least a few. For whatever reason, DJs like their privacy. Daniel Aagentah was tasked with making a sci-fi film prop helmet and decided to […]
Most modern digital cameras are perfectly capable of capturing photos of the stars. But many of them have trouble collecting the small amount of light available in a short amount of time, which means that you need to leave the shutter open for 30 seconds or more to get a decent exposure. That presents a […]
