Creating custom 3D printed LED bar graphs

Glen Akins has a nice build log on his 3D printed LED bar graphs: While building my zombie containment unit, I decided I wanted some LED displays or bar graphs to complement the containment status video running on the smaller secondary video monitor. Some other containment units used LED air pressure gauges from eBay. I […]

Build your very own drink mixing robot

Yu Jiang Tham designed and built his own bartender robot named Bar Mixvah, that is available on Github: I built a robot that mixes drinks named Bar Mixvah.  It utilizes an Arduino microcontroller switching a series of pumps via transistors on the physical layer, and the MEAN stack (MongoDB, Express.js, Angular.js, Node.js) and jQuery for the […]

3D scanning like a pro

Saulius Lukse writes, “Almost any sensor yields more interesting results if mounted on a moving platform. It’s time to mount TOF LIDAR on two precision rotary stages arranged for pan and tilt operation. Rig provides real-time position data along with distance to an obstacle. Using simple math we can calculate position in Cartesian coordinate system. […]

3DRacers, a 3D printed indoor racing game based on Arduino

3DRacers, the open source 3D printed racing game that you control with a smartphone: 3DRacers are 3D printed race cars that you can customize for free with their online editor. Once you have downloaded and printed your design, the electronics are a snap. The 3DRacer team has created an Arduino compatible control board that fits […]

Simple electric imp temperature logger

Marcus Olsson of Slickstreamer made this simple electric imp temperature logger with 3D printed case: I build this temperature logger for my father as a christmas present so he can use his phone to view the temperature at home. The device is build from a electric imp, TMP102 temperature sensor, battery and a charger. It loggs […]

Hacking a 3D printer into a tattoo machine

Here’s a cool instructable for a 3D printer tattoo machine: In october 2013, a famous design school in Paris, ENSCI les Ateliers, hosted a workshop organised by the French Ministry of culture. The idea was to use images, videos and sound fallen in the national pubic domain and use them in a sort of “Mashup”. The event […]

Open Electronics: Contest 3Drag/K8200

Open Electronics is launching a new contest for people who bought the printer 3Drag or K8200: Thus here is this 3Drag Competition, reserved for those who possess a 3Drag or a Velleman K8200 3D printer (based on the same design). Nowadays it’s plenty of this machines: in fact, thanks to the collaboration with Velleman, the […]

Single chip provides 3D images inside the heart and blood vessels

Researchers at the Georgia Institute of Technology have developed a new medical imaging technology that provides 3D imaging from inside the heart and blood vessels: The device integrates ultrasound transducers with processing electronics on a single 1.4 millimeter silicon chip. On-chip processing of signals allows data from more than a hundred elements on the device to be […]

Spherebot reloaded: Customize your Xmas

Boris Landoni from Open Electronics has designed and built another Christmas project the Spherebot, an open-source robot to draw on spherical objects: Let’s create a plotter to decorate Christmas Tree balls with writing and drawings. This machine: a printer, or better to say a plotter, which will draw with a marker on spheres at will, derived from models […]

OpenReflex, the open source 3D Printed Camera

Bozardeux wrote this Instructable detailing his OpenReflex, the open source 3D Printed Camera: The OpenReflex is an Open-Source analog camera with a mirror viewfinder and an awesome finger activated mechanic shutter (running ~ 1/60°s). What’s more, it is compatible with any photographic lens. All the pieces are easily printable on any recent RepRap-like ABS 3D-printer […]
