YouTuber “Peterbiglab” wanted an input for his DIY color-changing lamp, but didn’t want to use buttons or even have it detect claps, so he decided to make it respond to touch. Instead of using a capacitive sensor or force-sensitive resistor, he placed a microphone inside his lamp to hear inputs. An op-amp was also included […]
Mech-Dickel Robotics has designed a beautiful quadruped robot dubbed mechDOG, which utilizes a dozen servos for motion. This gives each leg three degrees of freedom, allowing the cat-sized beast to travel a meter in 8.46 seconds. While it won’t break any speed records, creating a walking motion on this sort of unstable platform is an impressive […]
As many of us are stuck at home these days due to COVID-19, Harrison McIntyre decided to do something fun and “make it rain candy.” What he came up with was a build that uses a flywheel to launch M&M’s — speed regulated using magnets and a Hall effect sensor, and aimed with a few […]
When working with Styrofoam, a conventional CNC machine like a router or laser cutter just won’t do. However, as shown in Michael Rechtin’s excellent video below, a hot wire can carve foam like butter, creating custom wings for RC aircraft or whatever else you can dream up. Rechtin’s build uses a double gantry system to […]
We’ll certainly remember this year, with many of us learning how to adapt and live a safe life-style under the pandemic. As many countries begin to initiate a relaxation of restrictions and we are starting to be able to leave our houses, arrange shifts to get into work (still observing safety measures), we might find […]
With many years of practice and discipline, you too can improve your basketball skills. Or you could just choose to play with Shane Wighton’s automated backboard that sinks nearly any shot that you take. The setup uses a Microsoft Kinect, along with a Windows-based computer to calculate the inbound ball’s trajectory. On approach it passes data to […]
As a fun weekend project at home, Arnaud Atchimon and his son came up with a DIY laser blaster game comprised of a 3D-printed shooter and target setup. Both devices are controlled by an Arduino Nano, and when the gun is powered up, you can either have 10 shots on target before a reload delay […]
As Niklas Roy puts it, “Currently, times are weird.” It’s hard to argue with his sentiment and in order to add a bit more positivity to the world, or at least the area near his Berlin workshop, he created an interactive pen plotter for his window. The idea is that while he didn’t know exactly […]
In order to stop the spread of COVID-19, many of us are wearing face masks when outside of our homes. While this can be effective, these coverings can be hot, inhibit breathing, and certainly make eating and drinking a bit difficult. What if they could instead be applied only when others are around? Chen the […]
Typing with your thumbs on a smartphone has become an everyday activity for many, but what if you could enter text by simply tapping on your index fingers? With BiTipText, that may soon be a reality. The researchers’ prototype consists of an interactive skin overlay made out of flexible PCB material, allowing an Arduino Uno and MPR121 sensor […]
