When you help your bumbling Uncle Gadget with all kinds of missions, you definitely need a watch that can do it all. Penny’s video watch from Inspector Gadget has a ton of features including video communication with Brain and Chief Quimby, a laser, a magnet, a flashlight, a sonar signal, and much more. To round out her …

As the name implies, a linear stepper is linear a variation of the rotary stepper motor design, radially cut and laid out flat. It is similar to the rotary version in operation and performance, and it typically runs as an open-loop system with the ability to provide high resolution at high speeds and accelerations. As …
For the last ten to fifteen years, optical drives have been fading out of existence. There’s little reason to have them around anymore unless you are serious about archiving data or unconvinced that streaming platforms will always be around. While there are some niche uses for them still, we’re seeing more and more get repurposed …
Arduino Laser Turret, Overview: In this project, I will demonstrate how to create an Arduino laser turret using servo motors and a two-axis joystick. I will provide the necessary code and a circuit diagram, accompanied by a detailed explanation of the project. This will enable anyone to successfully build the laser turret without encountering any …

Almost inevitably, when I try to climb the same route I’ll forget exactly what sequence of holds they used and end up following a slightly different path. Even when I remember exactly which course to follow, I’ll still wonder whether I’m doing it as quickly as the previous climber. Yes, I know that skill in …
For British kids of a certain age, their first experience of a computer was very likely to have been in front of a Sinclair ZX81. The lesser-known predecessor to the wildly-successful ZX Spectrum, it came in at under £100 and sported a Z80 processor and a whopping 1k of memory. In the long tradition of …

To extract information from QR codes and use a Barcode & QR Code HAT and a Raspberry Pi Pico. Description To extract information from QR codes and (even create your own barcode & QR Code using Python), use a Barcode & QR Code HAT and a Raspberry Pi Pico. What Are QR Codes and How Do They Work? …
In search for a compact and reliable LiDAR solution, researchers from Yokohama National University in Japan have developed a waveguide-based photonic chip that takes a laser beam as an input and steers light beams over a wide range of selectable angles, without involving any moving parts, not even MEMS. by Julien Happich @ eenewseurope.com Their results …

This Frankenstein Laser Cutter was built out of an old scanner and printer. The whole thing evolved around the instructable of Groover and his ‘Pocket Laser Engraver’. This is a Making-Of. Although a lot, if not everything, of the mechnical construction requires ingenuity I tried to document the complete build process as much as I …
Hello! This is the cheapest and easiest way to make a two-dimensional laser show projector. It uses just one pivoting mirror, powered by the focusing mechanism from a CD or other optical drive. They said it couldn’t be done, but Ljudmila‘s skunkworks GRL research facility delivers anyway! 😉 This design was first discovered in 2006 …
