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 […]

LaserPecker Pro-The Most Advanced Portable Engraver. Compact, Safe & Easy-to-use Laser Engraver LaserPecker recently announced a Pro version of their LaserPecker portable, affordable, compact laser engraver. Launched earlier this week on Kickstarter, the Laspecker Pro surpassed its modest funding goal of $10,000 in just 14 minutes and is currently approaching $200,000 with over three weeks left to

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

I enjoy creating sumo robots and am constantly searching for innovative sensors and materials to improve the speed and intelligence of my robots. I discovered the RPLIDAR A1, available for $99 on DFROBOT.com. I mentioned my interest in testing the sensor, and they offered me the opportunity to test it out. Once I obtained the

Laser harps are musical devices with laser beam “strings.” When the beam is blocked, a note is played by the instrument. Usually laser harps have the beams travel vertically in the shape of a fan or vertical lines. In this project, I built a laser harp with stacked laser beams that propagate horizontally. The beams

Meet Chartreuse! Chartreuse’s face follows you when you walk by. When she sees you, her eyes turn yellow and she gets a happy expression in her eyes. As you walk away, her eyes change to blue and she sadly turns away. Chartreuse is powered by an Arduino Uno, two servos, and a stepper motor and

For a course we followed at KTH in Sweden, we were assigned to create an artefact which could change shape. We made a fox shape artefact, supposed to remind you to take a break from work or studying. The general concept it that the fox will display breathing like motions. When you are starting to

Video games are great and all, but sometimes you just want the thrill of manipulating actual objects in addition to watching action on a screen. This must have been the reason why Nintendo’s Duck Hunt became so popular despite the simplicity of its gameplay. Prolific hacker [mircemk] similarly made a computer-plus-physical game called “Laser Shooter“,

*NOTE* THIS PROJECT IS DONE BY A GROUP OF STUDENTS FROM SINGAPORE POLYTECHNIC. Concept: Trigger gun when laser is blocked by intruding object. Note: Tilting is included for expandability but not used in this project. Skill Level: Basic soldering and basic metal works Things You Need: Toy Gun(Any will do, preferably a semi-auto) Continuous Rotation

This project uses an Arduino, a pair of speakers, and a laser pointer to create a laser projector able to trace out designs in a dark room. To power it, I’ve cannibalized a PC ATX power supply capable of delivering plenty of current for the speakers. Most of this project was directly adapted from the
