This large-format laser cutter was built from scratch for just $700

From blog.arduino.cc 2 months ago in Platforms Stores

When stuck between a cheaper yet small laser cutter and splurging on a much larger one, Owen Schafer decided instead to just build one himself. The project started with Schafer sourcing a 40W CO2 laser, which differs from a diode laser in that it uses gas heated with 16,000 volts to produce a...

Reading analog gauges with the Nicla Vision

From blog.arduino.cc 2 days ago in Platforms Stores

Analog instruments are everywhere and used to measure pressure, temperature, power levels, and much more. Due to the advent of digital sensors, many of these became quickly obsolete, leaving the remaining ones to require either conversions to a digital format...

This snake robot is large enough to ride upon

From blog.arduino.cc 2 days ago in Platforms Stores

If a robot is rideable, is it still a robot or is it a vehicle? We would argue that if it rolls on standard automobile-style wheels or even tank tracks, it is a vehicle. But James Bruton’s eight-wheeled robot snake...

A wearable, waterproof, wireless human-machine interface

From blog.arduino.cc 6 days ago in Platforms Stores

“Human-machine interface” (HMI) is a general term that describes any physical input or output hardware that people can use to interface with systems (like computers) and vice versa. That very broad definition usually applies to computer input devices like keyboards...

Affordable CAT scan machine built with an Arduino

From blog.arduino.cc 6 days ago in Platforms Stores

A CT (computed tomography), or CAT (computed axial tomography), scan is a type of medical imaging technique in which multiple X-ray “slices” come together to form a pseudo-3D model. CT scanners are the kinds of medical equipment that are so...

Building a DIY laser modem

From blog.arduino.cc 7 days ago in Platforms Stores

All digital communication ultimately comes down to transmitting ones and zeroes, but there are many ways to achieve that. One can encode that binary data as modulation in a radio signal or simply pulse electricity through a wire. But one...

This high-precision AC meter handles inductive loads

From blog.arduino.cc 1 week ago in Platforms Stores

AC (alternating current) meters are useful tools for measuring power draw. One might use an AC meter to monitor the power consumption of their devices and appliances with the goal of lowering their energy bill. Makers in particular can benefit...

Over-engineered robotic scalp scratcher knows all the moves

From blog.arduino.cc 2 weeks ago in Platforms Stores

Those cheap wire-arm head massagers are great at giving your scalp a nice, relaxing rub. But they’re handheld implements that force the user to either manipulate the massager themselves or talk a partner into performing the task. David McDaid decided...

LEGO-firing turret targets tender tootsies

From blog.arduino.cc 2 weeks ago in Platforms Stores

Stepping on LEGO bricks is a meme for a reason: it really @#$%&! hurts. LEGO brick design is ingenious, but the engineers did not consider the ramifications of their minimalist construction system. We’ve seen people do crazy things for Internet...

Reducing automotive fuel consumption with an Arduino

From blog.arduino.cc 2 weeks ago in Platforms Stores

Every car sold in the last few decades is equipped with an engine control unit, or ECU for short. Its job is to control nearly every aspect about the vehicle’s performance by reading various sensors and acting upon those inputs...

This air cleaner activates when it hears shop tools running

From blog.arduino.cc 2 weeks ago in Platforms Stores

Air cleaners are indispensable appliances in shop environments. Fine sawdust in the air can, for example, cause a variety of respiratory ailments in woodworkers. Even if the tool itself has a vacuum collection system, dust will fill the air. But...
