DIY Underwater Jetpack: Shark vs 100 kg of Thrust Makers at the YouTube channel CPSdrone took on the challenge of trying to outswim a hungry shark. They pictured getting on the Aquadart 770 Extreme, which is supposed to go at a maximum speed of 25 km/h and saw themselves becoming lunch. On a mission to outperform this underwater sea scooter, they started with thrust testing motors in a water tank in their workshop. They tried the… |

CARA: A Rope-Driven Quadruped Robot Without Gears or Pulleys Over the past year, Aaed Musa built a robot dog called CARA, short for "Capstans Are Really Awesome". The design does not involve gears or pulleys like traditional ones. CARA uses something called capstan drives that move joints using ropes wrapped around rotating drums. This system has numerous advantages, such as zero backlash, high torque transparency, low inertia, low noise, and low cost… |

Renesas Launches RA2T1 MCUs for Single-Motor Applications Renesas Electronics Corporation has launched a new group of microcontrollers (MCUs) named RA2T1, tailored for systems that control a single motor. The group is based on the Arm Cortex-M23 processor, running at 64 MHz, and is meant for devices like fans, power tools, vacuum cleaners, refrigerators, printers, and hair dryers. They have a 3-channel sample and hold (S&H) function to measure… |

DIY Robotic Arm with Brushless DC Motors and Raspberry Pi JesseDarr’s new project is different from the usual DIY robotics project. He has made a robotic arm called dARM. It is a robotic arm with 6 degrees of freedom, and most of the parts are 3D printed. He has used brushless DC motors for its working rather than servo motors. These are the kind of motors you would usually find in more advanced machines, and they help the arm move more smoothly and… |

DIY Smart Arduino Based Vacuum Robot with Wi-Fi Control The maker, Rizwan's Ideas, made a video on DIY vacuum cleaner 3 years ago. A lot of people loved the original, but many wanted Wi-Fi and IoT features, so he decided to upgrade it with better tech and smarter controls. When he received the DIY Flexi Robot Car Kit from OSOYOO, it turned out to be the perfect base for his new and improved version. The kit comes with Arduino Mega,… |

A 3D-Printed Launcher That Shoots Around Corners In a recent project released the thisismax Youtube channel explores how the Magnus effect can be used to steer projectiles in the air using a custom-built, 3D-printed ball launcher. Inspired by DARPA’s EXACTO project, which developed guided bullets that could change direction mid-flight, this experiment takes a much simpler approach. Instead of complex electronics, it relies on BLDC drone… |

A DIY PCB Motor That Spins at 37000 RPM Carl Bugeja, a maker well-known in the DIY community for pushing the boundaries of PCB-based motors, has released his new PCB motor design, which is capable of surviving over 1.6 billion rotations. Built on years of prototyping and testing, this latest iteration combines efficiency, compactness, and durability, all within a printed circuit board design. What started as a rudimentary experiment… |
