Those Gadget Masters who have school age children may be interested in this one: the Arduino Science Kit Physics Lab. The package been designed to support “scientific exploration” for school kids between 11 and 14. Experiment with forces, motion, magnetism, and conductivity. Students will make their own hypothesis like real scientists, then check their assumptions, […]

LoRa is a useful technology if you need to send data a long way at low power levels. Leveraging this, [5Volt-Junkie] decided to build a small pager named the LoRaNicator. Those who love a detailed build log will enjoy this. The pager features everything up to and including the kitchen sink. A Cortex M0+ runs the

While robotic arms can handle a wide variety of tasks, the specific job at hand will have a major influence on the type of end effector used. For sorting ferromagnetic parts an electromagnet might be enough, while for more accurate location a mechanical gripper could be employed. If you’re working with particularly delicate objects or

Potentially, one of the great things about having a device connected to the network is that you can update it remotely. However, how do you make that happen? If you use the Arduino setup for the ESP8266 or ESP32, you might try [scottchiefbaker’s] library which promises to make the process easy. Adding it looks to be simple.

The development team at AZ Electronic have launched a new smart water valve this month aptly named the Trident, which comes complete with its own smartphone companion application allowing you to shut off your water from any location in the world. Check out the video below to learn more about the design, features and functionality of

It’s wasn’t so long ago that RC transmitters, at least ones worth owning, were expensive pieces of gear. Even more recently than that, the idea of an RC transmitter running an open source firmware would have been considered a pipe dream. Yet today buying cheap imported transmitters and flashing a community developed firmware (if it

Classix Philly One Oh Seven Nine is your home for Philly soul right at the top of the dial, and now you know why this writer isn’t allowed on the Hackaday podcast. That phrase, ‘top of the dial’ doesn’t mean much these days because we all have radios with a digital display and seek buttons.

Over the last few years, LED candles have become increasingly common; and for good reason. From a distance a decent LED candle is a pretty convincing facsimile for the real thing, providing a low flickering glow without that annoying risk of burning your house down. But there’s something to be said for the experience of a real
THIS SUPER REALISTIC LED CANDLE IS SMOKING HOT Continue Reading
Debugging tools are critical to quick and effective development. Without being able to peek under the hood at what’s really going on, it can be difficult to understand and solve problems. Those who live on the Arduino platform are probably well acquainted with using the serial port to debug, but it’s far from the only

Instructables member “Lingib” has created a awesome Arduino powered Omni Wheel CNC pen plotter, powered by an Arduino Uno and Bluetooth module allowing the system to receive commands via a linked smartphone or tablet. If you’re not familiar with omni-wheels the unique wheels only provide traction in the direction of rotation. Any oblique force causes the wheel
