This project allows you draw in the air letters, symbols or other shapes – as you like. Controlled by the Arduino, the 7 simple leds blinking on and off – creating the illusion of floating text in the air. This combination of simple components with a unique program, allows to create  this instructable. Step 1: […]

A (not so) brief introduction. I’ve been working on a new robot called RoDI for a summer course at my Alma mater. RoDI is a low cost wireless robot to teach robotics and programming I started developing last year (reminder to self: I still need to post about it), but it wasn’t until a month ago that […]

I already have one project where arduino outputs audio signal to USB speakers via software 10-bits PWM.  In first, I was not satisfied with quality of sound generated via PWM. There are just not enough speed in arduino engine  to run PWM well.  For example for 20.000 Hz audio, PWM has to be at least 2 […]

Security system sensors such as motion detectors, reed switches, pressure mats, glass-break detectors, infra-red beams, and conductive film can be very handy for all sorts of things including home automation systems, interactive art installations – and sometimes even security systems! Almost all security system sensors provide a simple switched output that changes state based on […]

There’s a real beauty in long exposure photography.  Hours and days and weeks and months and even years can be condensed onto a single frame, and that frame will catalog the constants in our fast paced and forever changing lives.  However, the issue is that these photos can be difficult to capture using modern cameras.  […]

I was perusing Instructables one fine winter Saturday, when my 8 yo son came in and peered over my shoulder and saw this: http://www.instructables.com/id/RC-Lego-Car/ by sath02. My son is a huge fan of all things Lego, and loves robots and cars, and this was right up his alley. He immediately put it on his Christmas […]

Obstacle avoiding vehicle, continue in “3D Laser Range Finder” series ( project 1, project 2). The basic idea is the same, measuring distance using red laser pointers, CCD analog camera and Arduino UNO.  Modification was made in geometry.  Two lasers were set for “far field” obstacle detection, few meters in front of vehicle on left […]

Electronics work by interconnections. Normally, you’d think that a potential at one point on a wire is the same everywhere. However, that is (mostly) not the case and all kinds of aspects can pop up that make the potentials differ at different locations. Old-timers may remember connecting a printer to a computer and getting zapped […]

This is a instructable which is based on the Cube by Chr, ( http://www.instructables.com/id/Led-Cube-8x8x8/ ) by SuperTech-IT, ( http://www.instructables.com/id/CHRs-8X8X8-LED-Cu… ) and by das-labor.org, ( http://www.das-labor.org/wiki/Borg3d_Bauanleitung… ) but i think its better and easier. I started this Project without any skills from soldering toprogramming. First of all I apologize first for my poor English. Because of […]
