Seven-segment displays are normally diminutive items, able to show info from a clock or other device, in a size that’s easily tucked away when not needed. Jegatheesan Soundarapandian’s single-digit display, however, is just the opposite standing at nearly seven feet tall. The project is constructed out of cardboard, with a PVC spine for extra strength. Inside, […]
One of the simplest ways to make a mobile robot involves differential steering, where two wheels move at different speeds as needed to turn and a ball caster keeps it from tipping over. The MrK_Blockvader is an excellent take on this type of bot — demonstrated in the first clip below — featuring a 3D-printed blocky chassis, […]
Colin Furze decided that he needed a potato cannon for his DIY screw tank, and after making a manually loaded version, he automated the process. What he came up with uses a pair of linear actuators to push the barrel forward under Arduino control, allowing a potato-projectile to drop into the device’s chamber assembly. After a […]
Programming an Arduino to do simple things like turn on an LED or read a sensor is easy enough via the official IDE. However, think back to your earliest experiences with this type of hardware. While rewarding, getting everything set up correctly was certainly more of a challenge, requiring research that you now likely take […]
Irene Wolf is the owner a Passap E6000, a computerized knitting machine which features pair of needle beds, and decided it was time to give it an upgrade. In particular, she wanted the ability to control its rear needle bed automatically in a similar manner to the way the front is normally operated for extra […]
You may have seen Mark Rober’s automated dartboard or Stuff Made Here’s backboard, which use advanced engineering to create apparatuses that ensure you “can’t miss.” Now that summer is in full swing, what about a robotic cornhole board? Michael Rechtin decided to take on this challenge using a webcam pointed at the sky for sensing and […]
What if you were to use the hands of a clock not as an individual display, but as part of an array that moves together to form digits? That’s the idea behind Clockception by “Made by Morgan,” which utilizes 48 servo motors to drive 24 clock-like faces in an 8×3 grid. The build uses an Arduino Nano […]
Overall computer volume control is important, but what if you want to get more granular, adjusting sound from various applications individually? Rather than going through a series of menus and on-screen sliders, Ruben Henares’ Maxmix lets you do this on the fly. Based on an Arduino Nano, the simple yet stylish knob takes input from […]
If you’ve ever left an online comment that you later regretted, this anti-troll bot will keep that from happening again by letting you know when you’re being a bit too harsh. The device — which was created by Andy of element14 Presents — intercepts raw keyboard inputs using a MKR Zero board and analyzes them […]
DIY camera sliders are a great way to get professional-looking video shots on an amateur budget, but few can compare to the quality of this project by “isaac879.” His device features a pan/tilt mechanism outlined in a previous video, but in the clip below he’s attaching it to a piece of aluminum extrusion to enable it […]
