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…
Made by Origin Robotics, the open-source Arduino-based robot is a successor to the company’s previously-released Origibot. Like that model, it’s equipped with an included Android tablet, and can be remotely-controlled via an iOS/Android/Windows/Mac web app from anywhere in the world with internet access. You get two-way audio and video in addition to full control of the…
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…
Kodak and Smart International have collaborated on a professional, dual extrusion Kodak Portrait 3D Printer that runs a Linux-based 3DprinterOS on a Raspberry Pi 3 board. The $3,500 device is designed for engineering, design, and education professionals. The 3D printer features a five-inch color touchscreen with Kodak branding and can be accessed over Wi-Fi, Ethernet…
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…
If you find soldering enjoyable and relaxing, this is likely a good project for you. To create his clock, the maker Electronoobs has soldered LED filaments onto a steel wire frame. I’ve made some “nixie” tubes. These are actually 7 segments displays made with filament LEDs but placed in a plastic bottle so it will have…
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…
TrussFormer is the outcome of a research performed by Hasso Plattner Institute in Germany and the U.S. which have been working on a way to turn empty bottles into kinetic art. TrussFormer program is an integrated end-to-end software solution that allows users to design and 3D print large-scale kinetic structures using plastic bottles. The structure can then…
Adrian Lindermann has just created his small yellow companion taking inspiration from Jibo. Twinky can respond to voice commands via a SpeakUp click module, along with pressure on its face/touchscreen. Control is provided by an Arduino Mega, and Twinky can interact with other devices using a Bluetooth module. The robot’s head can even turn in order to point…
