One of the killer apps of 3D printers is the ability to make custom gears, transmissions, and mechanisms. But there’s a learning curve. If you haven’t 3D printed your own gearbox or automaton, here’s a great reason to take the plunge. This morning Hackaday launched the 3D Printed Gears, Pulleys, and Cams contest, a challenge to make stuff move using 3D-printed mechanisms.
Adding movement to a project brings it to life. Often times we see projects where moving parts are connected directly to a server or other motor, but you can do a lot more interesting things by adding some …read more
Circuits are beautiful in their own way, and a circuit sculpture takes that abstract beauty and makes it into a purposeful art form. Can you use the wires of the circuits themselves as the structure of a sculpture, and tell a story with the use and placement of every component? Anyone can exercise their inner artist using this medium and we loved seeing so many people give it a try. Today we announce the top winners and celebrate four score of entries in the Hackaday Circuit Sculpture Contest.
Let’s take a look at twelve outstanding projects that caught (and held) …read more
Drop what you’re doing and get thee to thy workshop. This is the last weekend of the Hackaday Circuit Sculpture Contest, the perfect chance for you to exercise the creative hacker within by building something artistic using stuff you already have on hand.
The concept is simple: build a sculpture where the electronic circuit is the sculpture. Wire the components up in a way that shows off that wiring, and uses it as the structure of the art piece. Seven top finishers will win prizes, but really we want to see everyone give this a try because the results are …read more
Entries into the Circuit Sculpture Contest tend to be pretty minimalist by nature, and this LED candle by [Amal Mathew] is a perfect example. The idea here was to recreate the slim and uncomplicated nature of a real candle but with a digital twist, and we think he’s pulled it off nicely with a bare minimum part count and exaggerated wire length that gives it the look of a thin pillar candle.
To give the LED a fading effect, [Amal] uses a ATtiny85 programmed with the Arduino IDE. His code uses the
analogWrite() in a loop to gradually increase and …read more
[Paul Gallagher] has spent years separating his tasks into carefully measured out blocks, a method of time management known as the Pomodoro Technique. If that’s not enough proof that he’s considerably more organized and structured than the average hacker, you only need to take a look at this gorgeous Pomodoro Timer he’s entered into the Circuit Sculpture Contest. Just don’t be surprised if you suddenly feel like your own time management skills aren’t cutting it.
While [Paul] has traditionally just kept mental note of the hour-long blocks of time be breaks his work into, he thought it was about time …read more
Dexter, an open-source, high-precision, trainable robotic arm has just been named the Grand Prize winner of the 2018 Hackaday Prize. The award for claiming the top place in this nine-month global engineering initiative is $50,000. Four other top winners were also named during this evening’s Hackaday Prize Ceremony, held during the Hackaday Superconference in Pasadena, California.
This year’s Hackaday Prize featured challenges with five different themes. Entrants were asked to show their greatest Open Hardware Design, to build a Robotics Module, to design a Power Harvesting Module, to envision a Human Computer Interface, or to invent a new Musical Instrument. …read more
We were contacted by [morbo] to let us know about a project on the AdaCore blog that concerns programming a PicoRV32 RISC-V softcore with Ada. The softcore itself runs on a Lattice ICE40LP8K-based TinyFPGA-BX FPGA board, which we have covered in the past.
The blog post describes how to use the Community edition of the GNAT Ada compiler to set up the development environment, before implementing a simple example project that controls a strip of WS28212b RGB LED modules. There are two push buttons changing the animation and brightness of the lights.
The source can be found at the author’s …read more
Cardboard is one of the easiest ways to build something physical, far easier than the 3D printing and laser cutting we usually write about here. So when Nintendo released their Labo line of cardboard accessories, it doesn’t take a genius to predict the official product would be followed by a ton of user creations. Nintendo were smart enough to provide not only an internet forum for this creativity to gather, they also hold contests to highlight some of the best works.
The most impressive projects in the winner’s circle combined the one-of-a-kind cardboard creations with custom software written using Toy-Con …read more
