Resistive load, constant-current power supplies, and a 3D printed desk lamp

Dr. Scott M. Baker published a new build: In this video, I build a 3D Printed Desk lamp. The basic design came from Thingiverse, but I repurposed my LM2576 Constant-Current design to serve as a dimmer.  It all started when I found an interesting lamp on thingiverse, which used 75mm air hose segments from another […]

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. […]

An open source 3D Scanner made with Raspberry Pi

Boris Landoni from Open Electronics writes about a new open source 3D Scanner made with Raspberry Pi: This being said, we may move on to talk about our 3D scan approach, that consists in using a linear laser, that is, one capable of drawing a vertical line having a constant luminous intensity, and in shooting the images that […]

More Delta printer upgrades: WiFi and silence!

David Crocker has been working on his Delta 3D printer project: After performing this upgrade, the printer is much quieter than before. This is because of the change from x16 microstepping on the Duet with A4982 drivers, to interpolated x256 microstepping on the Duet WiFi with TMC2660 drivers. The noisiest component is now the 40mm electronics […]

3D BRD viewer, a free tool to visualize CadSoft EAGLE PCB designs in 3D

Peter of Cytec BG writes, “My idea was for pcb designers to be able to quickly, whithout too much hassle, check their board for correct footprints (especially for connectors) and collisions between components. Currently one can change soldermask colors, silkscreen layers, move and rotate components around, change component models and import step files.” For more details visit […]

Simple 3D gesture control IC by Microchip

Microchip simplifies 3D gesture IC: Housed in an easy-to-manufacture SSOP28 package, the MGC3030 expands the use of highly sought after 3D gesture control features to high-volume cost-sensitive applications such as toys, audio and lighting. The simplicity of gesture-detection integration offered by the MGC3030 is also achieved through the company’s free, downloadable AUREA Graphical User Interface […]

Jan Henrik wrote this Instructable detailing the build of his DIY lens flare creating filter, with 3D printed parts: In this project i want to show you how you can build yourself a “Lens-Flare-Filter” for your DSLR or Digitalcamera! With the filter you can easy create a cinnematic look on your pictures and Videos, wthout spending much money on […]

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 […]

An open source, $2000, metal 3-D printer

Open-source metal 3-D printer: This paper reports on the development of a <$2000 open-source metal 3-D printer. The metal 3-D printer is controlled with an open-source micro-controller and is a combination of a low-cost commercial gas-metal arc welder and a derivative of the Rostock, a deltabot RepRap. The bill of materials, electrical and mechanical design […]

ZofzPCB 3D gerber viewer update

Zofz posted an update on his ZofzPCB gerber viewer we posted previously: ZofzPCB Gerber Viewer takes the Gerber file data from your CAD/CAM files along with a little additional information and transforms it into a 3D image with colours used to differentiate nets, customisable stackup dimensions and an Autopilot function that lets you sit back and enjoy the […]

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 […]

UV resin based mUVe 1 3D Printer source files released

UV resin based mUVe 3D Printer releases source files: The mUVe 1 3D Printer, an open UV resin based 3D printer was successfully funded on indiegogo back in April. As estimated, the first Ultimate kit was shipped out on Jun.20. Last weekend the team has completed building and shipping all of the Ultimate kits. Meanwhile […]

LaserOrigami: Laser-cutting 3D objects

Researchers at Germany’s Hasso Plattner Institute have developed an amazing new Laser cutting 3D objects, the LaserOrigami: LaserOrigami is a rapid prototyping system that produces 3D objects using a laser cutter. LaserOrigami is substantially faster than traditional 3D fabrication techniques such as 3D printing and unlike traditional laser cutting the resulting 3D objects require no […]
