The Lenco-MD turntable rethinks the classic concept of the turntable, making quality audio equipment accessible and customizable. Lenco-MD is the result of a partnership between the Swiss hi-fi audio manufacturer Lenco, the Dutch 3D printer manufacturer RepRapUniverse, and the Qeske knowledge-sharing community. It’s a modular kit that you build yourself from Lenco components and 3D-printed parts….
If you are searching for a perfect project for New Year’s Eve, maybe it’s just the thing. Cortex 2 is a great piece of engineering with some fascinating development and it was built up on the basis of Cortex 1: entirely 3D printed, the first rocket flew well, but the parachute failed to deploy mainly due to…
If you have access to a 3D printer together with a swimming pool new may be interested in a new Raspberry Pi project to create a 3D printed floating speaker. “My goal/inspiration for this project was to have a speaker that floats around like a buoy in the sea. Throw it in your pool or…
Why do you should buy an electric screwdriver when you can build it by yourself? The DIY electric screwdriver is fitted with a 9 g Micro server which has been modified for continuous rotation and connected to an Arduino Nano. The build uses a small thumb joystick for proportional control, and can accommodate a small hand driver…
Katrina Nguyen is currently a Biomedical Engineering graduate student at Carnegie Mellon University studying motor neuroscience research. Katrina designed an open source automated feeding system that aims to help researchers better monitor the daily intake of laboratory animals: it is called FED (Feeding Experimentation Device). FED utilizes open-source software and hardware. The system dispenses a…
Researchers Alec Peery and Dušan Sorma at Ohio University have been exploring a mechanical keyboard concept with a 3D-printed dampener built in, to avoid typing injuries. In fact the average computer user applies two to seven times the necessary force needed to activate a keyboard’s keys, slamming them down, then experiencing a sudden stop. So…
Using an array of 72 40kHz ultrasonic transducers to form standing waves of low and high pressure, the maker Julius Kramer has just created a 3d-printed acoustic levitator. 36 each are placed in the top and bottom shells of the device’s chassis. What’s interesting about Kramer’s build is that he does a great job illustrating how it works,…
Mug-O-Matic is a 3-axis drawing robot that can customize coffee mugs. It uses markers to draw anything you want on a coffee mug via manual controls, calculated algorithms, or even g-code. The mug can be washed clean with warm soapy water or the drawing can be made permanent by baking it in the oven. In its…
Instructables user MusaW has recently released a detailed guide to create a four leg (quadruped) robot using SG90 servo with servo driver and all controlled using WIFI Web server via smartphone browser: the total cost of the robot, including electronics and 3D printed components, is around US $55. There is a lot of NodeMCU variant in…
The maker Nikodem Bartnik has just created a 3d printed CNC machine that’s able to cut MDF and acrylic and can engrave aluminum. As for how well this CNC machine works, it’s pretty good. With the Gcode to cut an 80mm diameter circle out of MDF, this machine managed to cut a circle that was 80.02 mm…
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…
Desktop SLS 3D printing company Sinterit has introduced a new powdered material for desktop SLS 3D printers: PA11 Onyx. PA11 Onyx is a lightweight bioplastic made from plant-based resources. PA11 provides higher heat and chemical resistance than its relative of Nylon 12. Additionally, in Sinterit’s case, PA11 has the flexibility of 3D printing on the desktop. The…
