DAISY CHAINED SEVEN SEGMENT ART DISPLAY
Posted on: 15 Jun 2026
This seven segment art display makes use of a 81 seven segment red common cathode LED displays. The LEDs are arranged onto 100x100mm boards that each contain an Arduino Nano and 9 seven segment displays, daisy chained through three-pin headers located on the sides of the boards. The pins (power, ground, and serial) provide the signals necessary […]
HANG TEN WITH HELP FROM THE SURF WINDOW
Posted on: 15 Jun 2026
Unless you live in a special, unique place like Hawaii or Costa Rica it’s unlikely you’ll be able to surf every day. It’s not easy to plan surf sessions or even surf trips to most locations because the weather conditions will need to be just right. Not only the wave height (swell) but also the […]
BEAT THE STREETS WITH THIS TEXT SPRAYING ROBOT
Posted on: 15 Jun 2026
In the midst of striking for climate change awareness, you may need some extra hands. That’s what [Anred Zynch] thought when they built Strettexter, the text-spraying writing robot that sprays onto streets. The machine is loaded with 8 spray cans placed into a wooden box (a stop line with a wooden ledge to prevent the cans […]
COLLAPSE OS, AN OS FOR WHEN THE UNTHINKABLE HAPPENS
Posted on: 15 Jun 2026
Decades of post-apocalyptic Hollywood movies have taught us that once all the trappings of our civilisation have been stripped away, it’s going to be kinda cool. We’re all going to wear slightly dusty looking 1980s motorcycling gear, and we’re going to drive really cool cars. Except of course Mad Max is fantasy, and the reality is likely to be […]
REVERSE ENGINEERING A TWO-WIRE INTERCOM
Posted on: 15 Jun 2026
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] […]
ELECTRICITY MAKES SOFT ROBOTICS MORE LIKE US MEATBAGS
Posted on: 15 Jun 2026
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, […]
Inkplate 6 WiFI enabled e-paper display
Posted on: 15 Jun 2026
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 […]
RUNNING 57 THREADS AT ONCE ON THE ARDUINO UNO
Posted on: 15 Jun 2026
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 […]
Lightpipe 7-Segment Display
Posted on: 15 Jun 2026
What if I told you that you could build a display out of shoe laces!? Well that is exactly what I’ve done! Building your own seven segment display is nothing new, it’s a very common Arduino project, but I had an idea for this one so I said I’d give it a go, and I […]
IoT Split-flap Weather Forecast Powered by XOD
Posted on: 15 Jun 2026
Hi everyone! In this instructable, I tell you how to make split-flap display and show the current weather conditions on it. Also how to fetch the weather information from the Web using Wi-Fi and API. I am a fan of the XOD visual programming environment. With the 0.22.0 version, XOD entered the Internet of things. So […]
