Hello 3D Printed Dolly

Hello 3D Printed Dolly

[Ivan] likes to take time lapse videos. Using his 3D printer and a stepper motor he fashioned a rig that allows him to control the camera moving any direction on a smooth floor. The dolly has a tripod-compatible mounting plate and scooter wheels. An Arduino runs the thing and a […]

Arduino Vs. Arduino: Arduino Won

Arduino Vs. Arduino: Arduino Won

  For the last two years, Arduino LLC (the arduino.cc, Massimo one) and Arduino SRL (the arduino.org, Musto one) have been locked in battle over the ownership of the Arduino trademark. That fight is finally over. Announced at the New York Maker Faire today, “Arduino” will now go to Arduino […]

Cellular Automata Explorer

Cellular Automata Explorer

  Well all know cellular automata from Conway’s Game of Life which simulates cellular evolution using rules based on the state of all eight adjacent cells. [Gavin] has been having fun playing with elementary cellular automata in his spare time. Unlike Conway’s Game, elementary automata uses just the left and […]

Electronic Message In a Bottle

Electronic Message In a Bottle

  We remember going to grandfather’s garage. There he would be, his tobacco pipe clenched between his teeth, wisps of smoke trailing into the air around him as he focused, bent over another of his creations. Inside of a simple glass bottle was something impossible. Carefully, ever so carefully, he […]

The Arduino Sleeps with the Fishes

The Arduino Sleeps with the Fishes

  [Eric Dirgahayu] wanted to explore underwater with some sensors and cameras. First, he needed a platform to carry them. That led to his Arduino-controlled swimming fish. The fish is made from PVC and some waterproof servos. From the video (see below) it isn’t clear how much control the fish […]

Arduino Sketch: The Next Generation

Arduino Sketch: The Next Generation

  What was your first Arduino program? Probably an LED blinker — that seems to be the “hello world” of microcontrolllers. You probably moved on to things a little more complicated pretty quickly. At some point, things get harder because the Arduino lacks an operating system. There are operating systems […]

Arduino Detects Pants on Fire

Arduino Detects Pants on Fire

  Hard as it is to imagine, lie detectors have been sold as children’s toys for a number of years. A simple battery-operated device clipped to your fingers and would show the conductivity of your skin. The concept — which is probably not very reliable — observers that lying causes […]
