1. Introduction & Background Theory 1.1 Objective The objective of this project is to research, analyze, design, fully implement, and program an Arduino Uno microcontroller board to achieve PI control of the output power of a laser diode. Laser diodes require variable current sources for operation, as the current must be adjusted to maintain linear

A laser security alarm stands out as a highly effective system designed to detect any object or individual’s presence. Within a designated room, multiple laser beams are often employed. Reflective mirrors are commonly utilized to create a laser grid. When any object intersects these beams, triggering contact with the laser, the alarm system activates instantly.

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

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

This instructable will show you how to construct a laser tripwire that can twitter and grab an image from a webcam, as well as execute any command you can put in a bash script. This instructable is actually quite simple and is even suitable as a beginner arduino project. It requires a GNU/linux (or possibly Mac) operating

Maker Alessandro Grossi sent us this great DIY build for a 3D scanner built using a laser, a DSLR, and an Arduino controller. Allesandro is a Mechanical Engineer, holding a Ph.D. in product design. His day job involves helping designers and manufacturing firms develop and optimize products by means of FEM analisys and Computational fluid

We are a generation that love sound and light – can’t do without them really. Our most preferred time of day is night, or what we would call evening. We are particularly well acquainted with technology; doesn’t hurt these days. Our prerequisite for everything is that it be ‘cool’. Put it all together and in

This is a simple arduino based project that consists of a laser tripwire that, when triggered, will begin a countdown sequence on red, orange and green LEDs. I designed this to be an easy project for someone learning how arduinos work (like me). This is my first instructable so please bare with me 🙂 (I’ll
Laser Triggered Countdown Continue Reading
In this tutorial you will learn how to make your own 4 ft by 4 ft, Arduino controlled, 3 watt laser engraver / cutter (for thin materials) for around 300$. The main thing that separates this tutorial from other laser engraver tutorials on here is the roughly 42 x 42 inch cutting/engraving area. This project
