CNC milling is expensive, messy, and requires a lot of technical knowledge, which is why we all want the ability to 3D print metal. But while technologies like SLS metal printing do exist, they are generally out of reach of hobbyists. Fortunately, there is a secret third option: investment casting. Formlabs makes casting resins specifically […]
There’s a handful of things we truly need in order to live, and food and water comfortably make the list. Unfortunately, our water and food sources are not always safe. Throughout the world — even in developed countries — pollution, climate change, and poor management are damaging our access to clean water and food. And […]
One of the primary goals of wearable technology is to provide the user with capabilities and data that exceed their current abilities. And for motion, this has traditionally existed in the form of electrical muscle stimulation (EMS), where current is applied via electrodes to muscles, or as external motors and gearing that forcefully manipulate limbs. […]
A lot of newer cars have a really nifty feature called “proximity unlock,” which automatically unlocks the doors when the driver approaches while carrying their key fob. When paired with a push-to-start ignition switch, the driver never has to take their keys out of their pocket. But Nick’s 2004 Subaru STI is too old to […]
For the visually impaired community, most of their interactions on mobile phones are confined to text-to-speech (TTS) interfaces that read portions of the screen aloud. Refreshable braille displays also exist as a tactile means of communication, but their prices can get close to $15,000, putting them out of reach for most people. This is why Instructables […]
The Nano 33 BLE is one of our most popular boards, and for good reason. It’s small and 3.3-V-compatible; it comes with an embedded nine-axis IMU featuring accelerometer, gyroscope and magnetometer; it has a powerful processor; it offers a powerful Bluetooth® Low Energy module with an internal antenna that can be used to transmit data […]
In the past, DIY tech enthusiasts faced limitations when it came to creating small and intricate projects. However, the introduction of technologies like MicroPython and tiny microcontroller boards such as the Arduino Nano revolutionized the field. This enabled makers to build genuinely projects like wearables, miniature robotics, and ultra-thin gadgets, ushering in a new era […]
Building a capable robot is only half of the battle. To take advantage of that robot, you’ll need a good way to control it. When it makes sense, you can pre-program movements. But when you want to control a robot in real time, you need a suitable controller. Conventional joysticks and gamepads don’t translate well […]
Light painting is a photography trick that exploits a camera’s shutter. To ensure proper exposure in different lighting conditions, cameras have variable shutter speeds. If the subject is well-lit, then the shutter may only remain open for ten or so milliseconds. But if the subject is very dark, then a photographer may choose to leave […]
Long before Nicolas Cage ever portrayed the character on the silver screen, Ghost Rider appealed to an edgier subsect of Marvel’s audience. We won’t do a deep dive into the character(s) and their Faustian deals, but suffice it to say that Ghost Rider is a human man who turns into a flaming skeleton that rides […]
