This little wonder of electromechanical engineering came from inside a laser diode sled of an HP CT10L Bluray drive I’ve opened some time ago. The device on the picture consists of several parts, all easily fitting on a dime coin: a bipolar stepper motor with lead screw, a linear stage, a lens, and even an […]

*NOTE* THIS PROJECT IS DONE BY A GROUP OF STUDENTS FROM SINGAPORE POLYTECHNIC. Telemetry – Solar Cells Our project is using Arduino with the ZigBee to transmit and receive data from the solar cell. Data will be shown in the LCD and the software called “X-CTU”. Components used: 1 Arduino Uno 1 ZigBee Shield (Transmitter) […]

Last year my Wife and I started a new tradition of building a Gingerbread house for Christmas. We had a few nicely decorated houses last year, and I wanted to do a little more this year. Adding LEDs makes everything better, so that is exactly what I did! This instructable will show you how to […]

Today we’ll expand Arduino’s digital resources thanks to an I2C bus equipped shield and we’ll allow the management of the board via a bluetooth connection RN-42 through an Android systems. All Arduino boards feature a number of digital I/Os. For the simplest projects, such resources are usually more than sufficient, but in those where they […]

Part 1 – Test Circuit and Test Code Introduction Getting your Arduino to transmit via the radio initially may seem daunting but its actually pretty simple. Please freely substitute the word “Arduino” for any micro-controller you wish to use. The example below works for 5V and 3.3V micro-controllers. Please read this : This may be […]

Hi All! I have wanted to do something fun with my bedroom for a while now and the Make it  Glow challenge provided me with a reason to do so. A few months ago I acquired a strand of GE-35 Color Effects lights and owing to the inherent dangers of controlling wall voltages, the strand […]

Everyone has USB gadgets.  It’s pretty much a fact of life.  Another fact of life is that these USB gadgets also continually run out of power when you most need them.  No need to fear, solar power is here!  Ditch those crazy wall adaptors, throw out the laptop, and start making your own solar charger! […]

This circuit will take a light reading then display a number between zero and 99. Step 1: Parts you will need Major Components in Project To make the 0-99 LED display you will need… ~ photo resister ~ Arduino ~ 9 different wires ~ 2 seven segment led displays ~ bread board ~ staples ~ […]

Combine three inexpensive LED matrix display panels, an Ardweeny microcontroller and a standard PS/2 computer keyboard into your own go-anywhere, instantly updatable 768-pixel digital message board. The code can hold up to six lines of text with a maximum of 100 characters each. Pressing a key on the keyboard gets you to input mode. Use […]

I’ve reached the point where I need to think how I’m going to control the motor & linear actuator for my solar tracker. Things to consider – Must be able to go forwards and backwards – so that makes 4 channels, 2 for each motor. Must be able to provide enough power to drive the […]
