“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- This SpaceX fan created a levitating Starship lampAlthough you might not be able to build or house your own SpaceX Starship, YouTuber “Embrace Racing” has created a levitating lamp model that will be much more attainable for non-multi-billionaires. The lamp’s landing pad features an Arduino Nano inside, which is used with WS2812 LEDs to simulate the smoke plume of the rocket through a 3D-printed […]
- AAScan is an open source, Arduino-powered 3D scanner that uses your phone3D scanners are amazing tools that literally let you turn everyday things into three-dimensional computer models. As seen on Reddit, if you want to make one yourself — using little more than a spare Android phone, Arduino, stepper motor, and 3D-printed parts — the AAScan by QLRO could be an excellent option. The device spins an […]
- A DIY digital readout for your wood latheSmall wood lathes don’t typically come with an RPM readout, so after obtaining such a machine several months ago, engineer Zach — also known as ‘byte sized’ — decided to build his own custom display. The device uses a Nano for control, along with a Hall effect sensor to pick up on four magnets attached […]
- arduino-cli 0.8.0 is here!Our dev team is grateful for the high quality contributions that the project is receiving, and is working hard to collect all the lovely feedback we have received to shape the Arduino CLI into the best tool possible for the community! Highlights of our latest release include: Resource usage improvements Better libraries handling Bug fixing […]
- Arduino 1.8.12 is out!Today, we are excited to announce the arrival of the Arduino IDE 1.8.12. Wow! Another release just after two weeks, you ask? Well, we fixed some serious bugs related to the compiler, and more importantly, we had to take a step back with respect to the transition to the new Java Virtual Machine from OpenJDK. […]
- This retro-looking rotary cellphone is free of modern-day distractionsWhat we carry today in our pockets is nominally called a “phone,” but more often than not we’re using it to do various other computing tasks. Justine Haupt, however, wanted an actual phone that “goes as far from having a touchscreen as [she could] imagine.” What she came up with is a rotary cellphone that’s not […]
- Mechanical 7-segment display made with micro servos and an Arduino MegaFlip displays are an interesting piece of technology, physically moving segments into place that stay put until other information is needed. Michael Klements has been especially fascinated by these devices, and after inspiration from another project, he decided to craft his own. His version utilizes 14 micro servos to flip segments into a visible position, […]
- The ZT-2020 is a portable SunVox synthSunVox synth software allows you to create electronic music on a wide variety of platforms. Now, with his ZT-2020 project — which resembles a miniature arcade game — YouTuber “fascinating earthbound objects” has a dedicated input scheme. This cabinet prominently features a wide array of buttons, a directional input from a PlayStation controller, and 16 […]
- This joystick-controlled machine draws light trails using a laserLasers are awesome. Glow-in-the-dark surfaces are, too. As seen here, Justin and Brett were able to combine the two into an excellent drawing machine made from scrap materials and discarded wood. Their device uses a pair of gearmotors under Arduino control to actuate a rack-and-pinion gantry system over a canvas painted with phosphorescent powder. A […]
- Carve 2.5D shapes out of foam with this Arduino-controlled hot wire cutterYou may have a 3D printer or other “digital” tools like a laser engraver or CNC router, but what if you want to work with Styrofoam? As How To Mechatronics demonstrates in his latest project, many of the same techniques used there can be implemented to make your own Arduino-powered hot wire cutter. This build […]
