Build you own voice-controlled robot car! Alexa analyzes your speech and sends data to a server which computes them. Then data are sent bach to Raspberry Pi Zero which gives commands to a Micro:bit board.

The Glowtie is a light-up bowtie! It clips onto the top button of your dress shirt and can display any number of colors and animations. When you turn the Glowtie on, the onboard ESP8266 hosts an AP network that you can connect to with your phone to control the lights. The Glowtie is based on the ESP-12F…
Usually there are two ways to look forward to buy a Raspberry Pi: first, think about a strange thing to make, and then go to the website; or second, buy the Raspberry Pi board having no idea of what you are going to do with it. Usually, I buy things and only after that I…
How To Mechatronics has come up with a bender that not only twists wire left and right, but can rotate to create three-dimensional shapes. The 3d wire bending machine is powered by an Arduino Nano, which controls three stepper motors for wire manipulation via DRV8825 driver boards. A servo motor is also implemented in order…
Here’s a complete writeup of what happened yesterday 3/10 at Rome Maker Faire. Overall it was a great show with I think more than 1000 attendees (during weekday, in Italy, it’s pretty huge) attended an overcrowded Palazzo dei Congressi in Rome’s EUR, the neighborhood that is the best expression of Fascist era architecture. In this…
Converting 3D modeling files to STL can be problematic. Additionally, 3D printing often lays bare file errors such as nonmanifold issues, flipped vertices, holes in the mesh and intersecting objects. Meshes for 3D printing need to be watertight and manifold. A free cloud-based STL and 3MF file fixing is MakePrintable by Mixed Dimensions. MakePrintable is…
Mike’s Robot Dog is an Arduino-powered robotic pet with a lot of 3d printed parts and features four servo-driven legs, with two-axis shoulder movement, as well as an articulated knee joint. It’s capable of picking itself up off the ground, and can then walk using a slow side-to-side gait. To make the dog move, power…
