Minimal Aesthetic Clock Using Simple Motor Mechanism Minimal Aesthetic Clock Using Simple Motor Mechanism

Russian DIY creator AlexGyver has completed his latest “Challenge Accepted” project: a big, good-looking wall clock made using 24 small stepper motors called BKA30D-R5. These are the same kind of tiny motors you find inside car dashboards to move speedometer or fuel gauge needles. Each motor has two shafts, but he only uses one to control a custom pointer. With 24 of…

Simplified SmartKnob for makers and hobbyists. ESP32 Makes SmartKnob Simpler and Smarter

This is a simpler, more beginner friendly version of the original SmartKnob designed to make smart haptic controls easier to build and understand. By removing much of the complexity found in earlier designs, this version is easier to assemble and supports more motor options, making it an approachable project for hobbyists and first time builders alike.

Kokensha Tech redesigned the…

CARA: Rope-Driven Robot Dog Without Gears 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…

Interfacing TMC2209 with Arduino Interfacing TMC2209 Stepper Motor Driver with Arduino UNO – Basic Direction and Stepping Control

In this comprehensive TMC2209 Arduino tutorial, we'll walk through a complete example of how to interface a Bigtree Tech TMC2209 stepper motor driver with Arduino UNO for precise directional rotation and step control. This stepper motor driver guide is perfect for beginners looking to learn Arduino stepper motor control using digital signals to move motors…

Real-Life Rideable Transformer Robot Built This Transformer Robot Was Built to Be Ridden, Not Just Looked At

A maker built a real-life transformer robot that switches from a car to a robot, just like in the movies. The build is designed for someone to ride, much like a toy car. The robot uses Gimson Robotics 99.5:1 gearhead motors with additional 3D-printed two-stage gear reductions. Six motor assemblies power all leg joints.

It uses AS5047 magnetic encoders to track joint positions, allowing…

Hybrid Drone That Flies And Drives Seamlessly DUAWLFIN, A Drone That Can Both Fly and Drive Using the Same Motors

Researchers from UC Berkeley have developed a unique hybrid drone that both flies like a quadcopter and drives on the ground using the same motors. Unlike the average drone that needs separate motors or propellers to move on the ground, DUAWLFIN uses a clever mechanical system called a differential drivetrain to switch between flight and wheels. The spinning of propellers is not required while…

DIY One-Wheel Electric Board From Hoverboard Junk Hoverboard to DIY Electric Ride on One Wheel

A combination of an old hoverboard, a go-kart tire, and some clever engineering apparently gets you a functional one-wheel electric ride that rides like a snowboard both on and off the road. A DIY creator from the YouTube channel Well Done Tips took what he believes to be one of the most useless electric rides ever made and transformed it into a surprisingly cool custom one-wheel electric…

DIY Robotic Arm 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…

AI Pet Dog - Bao Bao, AI Pet Dog

I wanted to build a Pet Robot Dog for my daughter. She loves dogs and would love to have a pet dog. As I can't get her an actual dog so thought I will get her something to play.This robot dog responds to "Hi Bao" and "Hi Ping" for names (wakeup words).Below are the features of Bao

Face Recognition: Bao will detect registered faces…

3D Magnetic Resolver IC New 3D Magnetic Resolver IC with Triaxis Hall Technology Optimized for Robust Motor Design

Melexis has revealed the new AEC-Q100/ISO 26262 compliant pico-resolver MLX90381 that combines the advantages of a small outline and reliable analog outputs providing sine and cosine signals. This 3D magnetic pico-resolver with Triaxis Hall technology can be used for absolute rotary position sensing and, leveraging its low latency and fast response,…

Harmonic Distortion in Induction Motor How Harmonic Distortion Affects your Induction Motor Performance

Harmonic distortion has always been a problem for electrical engineers as it leads to heavy power loss in AC induction motors and transformers. These losses in AC induction motors leads to excessive heating, which happens because of additional copper losses and iron losses (eddy current and hysteresis losses) in the stator winding, rotor circuit, and rotor laminations. This…
