“Gentem”…. ói nós aí de novo! Tá chegando a hora de exercer a obrigação cívica de procurar uma urna e votar. Digo obrigação e não direito de votar, em razão
Coisas do Arduino- Vintage LED display prototype revived with ArduinoPatrick Hickey has been collecting retro LED indicators and displays for decades, and his rarest item is an HP 5082-7002—a 5×7 dot matrix LED display in a beautiful gold and (possibly) sapphire enclosure. This device is so rare, in fact, that he believes it to be a prototype, somehow relegated to eBay for gold salvage. […]
- 1980s plotting device turned into a handheld whiteboard toolWriting on a whiteboard isn’t an easy task for many people, including instructor ‘Kenyer,’ whose lettering can be on display for a semester or more. Rather than accept his imperfect penmanship, he modified a 1980s-era Rotring NC-Scriber—originally meant for mechanical drawing use—to do this for him. His project runs on an Arduino Uno and motor […]
- Simulating a flip clock on an Arduino-driven LCD screenAlthough flip clocks may be extremely interesting electromechanical devices, with rolling flaps to show what time it is, they’re also fairly complicated if you want to build one yourself. Mark Wilson, however, took a different approach with his project, simulating the output on a 320×240 LCD display. The clock is powered by an Arduino Uno […]
- This thermochromic 7-segment display colorfully shows the temp and humidityInstead of controlling his temperature and humidity display directly, maker mosivers did things a bit differently, driving the temperature of each segment with a Peltier element, or thermoelectric cooler (TEC), to change its color. Each segment is made out of a thermochromic material, cycling from a black off state to a greenish hue when on, […]
- Horizontal laser harp is like none you’ve ever seen beforeApparently not content with a traditional laser harp, Jonathan Bumstead set out to take things in a different direction. What he came up with is a device whose laser strings are arranged horizontally, and loop though its boxy structure for an amazing audiovisual effect. The aptly named Upright Laser Harp is divided up into six […]
- LED matrix made touch sensitive with infrared controlIf you’d like to integrate touch functionality to your LED project, then tuenhidiy may have just the thing for you. The setup uses 16 pairs of IR emitter and receivers arranged down the length of a bi-color 16×32 matrix to tell when one has inserted a finger or other object into an area. When sensed, […]
- Automating a chop saw with ArduinoYouTuber “Absorber Of Light” needed to cut thousands of tiny aluminum pieces with a chop saw, and after paying someone to do this for him, decided to instead automate the process. His system is controlled by an Arduino Uno, and moves strips of aluminum under the saw using stepper motor and threaded rod assembly—a sort […]
- Toy piano converted into a self-playing instrumentUpon obtaining a small toy piano, Måns Jonasson went to work “Arduinoizing” it with 30 solenoids to hammer out tunes. A MIDI shield is used to pipe commands from a computer to the Arduino Mega that’s used for control, and after experimenting with discreet wiring and electronics for each of the solenoids, he switched to […]
- Create Agent – Windows installer tampering while preserving Authenticode signatureArduino Create Agent is a plug-in that was designed to help Arduino users connect their devices to the Arduino Create platform. The plug-in lets your browser communicate with your device’s serial port from a web application. We chose Bitrock’s InstallBuilder, a powerful and easy to use cross-platform installer creation tool, for generating the Arduino Create […]
- Reviving an old CNC router with ArduinoMakerspace i3Detroit was the recent recipient of a free yet non-functioning CNC router. While out of commission when received, the device’s mechanical components and motors appeared to be in operational condition, plus it had a large work surface. The decision was made to get the CNC up and running for now, with the eventual goal of […]
