Arduino Round Segment NeoPixel Clock Digital clocks are one of the most popular Arduino projects, and most of them use traditional seven-segment displays to show the time. While these displays are simple and reliable, they usually have the same familiar rectangular shape and monochrome appearance. When I decided to build a new digital clock for my room, I wanted to create something that worked like a seven-… |

Someone Turned 4 Trashed Laptops Into a Private ChatGPT That Got Faster With One Laptop Removed Maker Joe C-J has repurposed four discarded Lenovo ThinkPad L380 laptops into a working, self-hosted AI computing cluster, capable of running large language models entirely offline. Each of the four motherboards was stripped from its laptop chassis and mounted into a custom 3D-printed frame, designed in Fusion and reprinted to accommodate a fourth node after an earlier three-node version… |

Jurassic Park's Legendary Dinosaur Input Device Recreated Using Modern Technology Long before today's advanced motion capture systems became commonplace, Industrial Light & Magic (ILM) developed an ingenious hardware solution known as the Dinosaur Input Device (DID) for Jurassic Park. Instead of animating dinosaurs frame by frame with a mouse, animators manipulated a physical dinosaur puppet embedded with magnetic rotary encoders at every… |

How to Build an Interactive Robotic Arm using PIC Microcontroller? Robotic arms are widely used in industrial automation, research, and educational projects. Building and controlling one is a great way to learn the fundamentals of embedded systems, motion control, and robotics. In this project, we will design and build a 4-degree-of-freedom (4-DOF) robotic arm controlled… |

Moody Mush: DIY Interactive Mushroom Robot That Follows Your Touch Moody Mush is an interactive, mushroom‑shaped robot built by SayaNIGHT. It has three modes of operation. In Mode 1, it functions as a desk lamp; the LEDs and cap (the head portion) are controlled with an IR remote. In Mode 2, the LED colors are adjustable with the same remote, but the robot also reacts to touch. Different movements and sounds occur depending on the type of touch (a short touch… |

Repurposing a Wear OS Smartwatch as a Smart Gear Shift Display A DIY maker has repurposed an old smartwatch into a custom gear knob with an integrated display. Instead of letting the aging smartwatch collect dust, the project reuses its display, sensors, and processing hardware inside a 3D-printed gear shifter housing. The result is a unique modification that displays the vehicle's current gear position directly on the gear lever itself. What I… |

Arduino Obstacle-Avoiding Robot Rebuilt 7 Times Larger A Youtube channel named UncleStem has taken DIY robotics to a completely new level by building a giant obstacle-avoiding robot powered by a fully functional oversized Arduino Uno. The project recreates a classic Arduino obstacle avoidance robot at seven times the original size while still maintaining real working electronics inside. From giant DC motors and oversized jumper wires to a massive… |
