The Etch-A-Sketch was a toy that demanded mastery. Some grew capable of creating masterful artworks, while others struggled to do more than a jumbled mess of angry, angular lines. The inherent limitations of being able to only draw a singular, connected line are all part of the fun, of course, and [gatoninja236] recreated that in a […]

The Quadrivium EnsembleBot project is a mashup between old school musical instruments and the modern MIDI controlled world. Built by a small team over several years, these hand crafted instruments look and sound really nice. The electronics side of things is taken care of with a pile of Arduinos and off-the-shelf modules, but that doesn’t mean the
THE QUADRIVIUM ENSEMBLEBOT IS A LABOUR OF LOVE Continue Reading
Arduino enthusiasts interested in creating a changeable RGB LED matrix might be interested in the new Pixie Chroma displays created specifically for the Arduino platform by the engineers and develop and team over at Lixie Labs. Features of the Pixie Chroma displays include Quad Mode and Shortcodes enabling you to quickly create scrolling messages in
Pixie Chroma mini Arduino LED matrix displays from $45 Continue Reading
The Arduino is a powerful platform for interfacing with the real world, but it isn’t without limits. One of those hard limits, even for the Arduino MEGA, is a finite number of pins that the microcontroller can use to interface with the real world. If you’re looking to extend the platform’s reach in one of

[Daniel Dakhno] kept ending up in a situation where the ability to read the status of, or control a few digital IO pins with minimal effort, would be terribly useful. Not wanting to keep compiling code, for such simple needs, they instead used a nRF51-based module as a physical interface and produced a general purpose

A few months back, I posted an Instructable on my Raspberry Pi movie player tucked into a VHS cassette. Since then, I have built several for friends and family, and have simplified the process. Using a Raspberry Pi v3, we no longer need a USB hub and no longer need to remove the GPIO. This tutorial requires

a simple 3 buttons on-off with pic12f629. it’s written with MikroC Step 1: The Code… start the code with ”int”———————————————————- int x0,x1,y0,y1,z0,z1; ////// with this the GPIO outputs could stay on or off void main() { GPIO = 0x00; ////// all outputs are 0 CMCON = 0x07; ////// Disable CMCON PORT TRISIO = 0b00111000; //////

We’re all pretty well-acquainted with the obstacle avoiding robot. These little inventions use a proximity sensor to detect an object in front of the robot, then circumvent the object accordingly. Brown Dog Gadgets’ little robot really caught our eye, mostly because it’s kind of cute. This little robot combines a few LEGO pieces, Arduino, and Brown Dog
MAYBE ONE OF THE MOST ADORABLE OBSTACLE AVOIDING ROBOTS YOU’VE SEEN Continue Reading
Singapore-based startup Kobol has successfully launched its open-spec “Helios4” NAS (network-attached storage) SBC and fanned system. In May 2017, Kobol tried to launch the open-spec Helios4 SBC and fan-equipped system for NAS on Kickstarter. Though a total of 337 backers helped to raise $74K for the Helios4, Kobol fell short of its $110K funding goal. The Helios4 NAS SBC
