In this instructable I will show you how you can make your own Atting programming shield for the arduino and then use the arduino as a programmer. Usually If you don’t have a shield you can do a breadboard version to program the ATtiny. (Step1) But here I’ll show you how to program it and […]

You might remember my first set of lights that I put on my dad’s skates. Well those weren’t bright enough and they were a lot of work because I didn’t know how to make PCBs. In this i’ble I’ll cover how to make your own custom PCBs in under an hour! Keep in mind, if […]

This Design Idea shows a way to drive low-power electronic circuits using a single 1.5V cell. The design is based on a free-running oscillator that drives a flyback transformer to  generate a controllable higher voltage. It can be used to power analog circuitry, microcontrollers, and any other light loads. The power circuit was designed, simulated, […]

The Arduino team is now shipping their latest creation – the Leonardo. It is the first Arduino to use Atmel’s ATmegaXU4 series chip with built-in USB. This change is big and it has big benefits. In addition to the built-in USB, it offers more digital and analog pins. This step by step  guide gives you […]

Project Goal The goal of this project is to create a low resolution display of graphical art that interacts with people who are handling it. My basic idea is to create such a “magic box” with a LED matrix on one side. It should be small enough that it can be held by hands. Also, […]

The Birth of RoboDolly The conception of the RoboDolly can be traced back to my senior year of high school.  This aluminum ornament evolved from housing a few flashing lights to displaying a fully handmade LED matrix.  The final product was awarded to my robotics programming mentor; it now sits on his desk and gleams […]

Infrared headphones can be used for listening to music or television cordlessly. The headphones utilize a transmitter that connects with audio cables to the audio source, such as a home entertainment center. The transmitter utilizes light-emitting diodes (LEDs) to direct a focused beam of invisible pulsating light towards a receiver built into the headphone set. […]

This Instructables is about upgrading a plush toy to give it the ability to sing when baby presses its belly. Most importantly : it will not play a stupid pre-recorded music, but actually sing mommy’s songs, with mommy’s voice ! This project started with two goals in mind: customizing a nice gift for my baby, […]

In the past five weeks, we have considered and built three projects, ranging from: optical sensing, electromyography (EMG), and galvanic skin response detection. Initially, our project was using an optical sensor and EMG to detect finger movement for applications, such as: playing piano and Morse code. However, after completing the hardware, due to issues with […]

I found a pressure sensor matrix that we could adapt to a pressure sensor patch on the stomach of the women in labor on this webpage (see below). It gives instructions how to build a pressure sensor by using two pieces of cloth and conductive thread! If I understand it right, you just have to […]
