There was a time when an intercom was simply a pair of boxes with speakers joined by a couple of wires, with an audio amplifier somewhere in the mix. But intercoms have like everything else joined the digital age, so those two wires now carry a load of other functionality as digital signalling. [Aaron Christophel] […]

Building a future where robots work alongside humans relies heavily on soft robotics. Typically this means there will be an air compressor or a hydraulic system nearby, taking up precious space. But it doesn’t have to. Engineers at the UC-San Diego Jacobs School have created a soft robotics system that uses electricity to control flexible actuators,
ELECTRICITY MAKES SOFT ROBOTICS MORE LIKE US MEATBAGS Continue Reading
Makers developers and small businesses may be interested in a new Wi-Fi enabled e-paper display that will soon be launching via the Crowd Supply website offering a display that can be programmed using the Arduino IDE and is based on the ESP32. “A powerful, Wi-Fi enabled ESP32 microcontroller makes this six-inch e-paper display – recycled from a
Inkplate 6 WiFI enabled e-paper display Continue Reading
When one thinks of the Arduino Uno, one thinks of a capable 8-bit microcontroller platform that nonetheless doesn’t set the world alight with its performance. Unlike more modern parts like the ESP32, it has just a single core and no real multitasking abilities. But what if one wanted to run many threads on an Uno

Retired scientist [Mark Howe] spent the last couple months making an animatronic movie featuring his LEGO lunar lander in a video recreation of the Apollo 11 moon landing (also embedded below). [Mark] is not only the producer, but serves as the technical director, set designer, and cameraman as well. He designed and 3D-printed a custom special effects

[Andrew] wonders why the SerialUSB() function on the Cortex M3-based Arduino Due is so much faster than Serial() on the Uno or Nano, and shares his observations in this short video. He sets up an experiment with a simple sketch on both boards and uses Wireshark to evaluate the results. Data is sent in the USB packets in groups of
ARDUINO SERIAL VS SERIALUSB Continue Reading
FPGA guru [Max Maxfield] recently took a look at the XLR8 (pronounced accelerate) board from a company called Alorium. On the surface, it looks like another Arduino UNO clone. But instead of a CPU, it contains an Intel MAX10 FPGA that runs a softcore AVR processor. Of course, that’s only part of the story. If the board was
ARDUINO AND FPGA DONE DIFFERENTLY Continue Reading
If you are looking forward to the official Arduino Day live stream you will be pleased to know that it will start on March 27th at 4pm CET on Arduino’s online channels. “Everything’s in place and ready for the global celebration of Arduino’s sweet sixteenth birthday, including some amazing interviews, demos and talks” explains the

Tiny OLED displays are an absolute must-have in the modern parts bin, so what better way to show your allegiance to the maker movement than with a pair of Arduino-compatible OLED glasses? Created by Arduboy mastermind [Kevin Bates], these digital spectacles might not help you see any better — in fact, you’ll see a bit worse
THE FUTURE’S SO BRIGHT, YOU GOTTA WEAR ARDUGLASSES Continue Reading
Since the ESP8266 came on the scene a few years ago and revolutionized the way microcontrollers communicate with other devices, incremental progress on this chip has occurred at a relatively even pace. First there was the realization that code could be run on the chip itself. Next the ESP32 was released which built more on
