Massimo Banzi presented at TEDGlobal: "open source and the makers movement" is the revolution that is going on. "You don’t need anyone’s permission to make something great." and "we don't have 5 years to become electronic engieers, we have 1 month". Arduino is an amazing platform to start and build devices and Massimo summarize 7 years in an exciting 15 minutes…Continue

On this tutorial, we will show how to use the Cellular Shield with Arduino. This shield can make and receive phone calls, send and receive SMS messages and transfer data. To use this shield, you will need a SIM card.
First, we will show how to send and receive SMS. Let's take a look at the…Continue
Greetings to Garagelab! My name is Garrett and I'm posting here today because the TokyoHackerspace is moving to a new location and is selling Chumby Hackerboards to cover the cost at a heavily discounted price. A while back, Safecast picked up a case of Chumby HackerBoards, which they intended to use in crowd sourced radiation monitoring across northern Japan. Design constraints changed, and so Safecast was left holding onto the Chumbys.
Fast forward 6…Continue

Blair Neal created an analog 3D display using Crayola Glow Books. Each frame is draw with a glow pen on one plastic panel. When the panel is illuminated, the draw appears. So, controlling the LEDs with an Arduino Mega, he could control what will appear on the "screen".

On this article, we will talk about the memory types that we can found in microcontrollers like ATMegas, PICs and 8051s. Usually, available memory varies depending on the microcontroller manufacturer and model. Here we will explain the most common memory types: RAM (Random Access Memory), ROM (Read-Only Memory) e…Continue

Here is and clever use of new technology to bring to real reel recordings:
Using a slightly modified Square mag stripe reader, an RCA MODEL SRT-403 Tape Recorder, an iPod Touch, and requisite audio software, maker Evan Long got a modern digital media player to record and play back an obsolete paper reel-to-reel format from the late 1940s.

This project could be the first Arduino powered satellite. And they are open an opportunity, so anybody can join and run his own experiments.
ArduSat is a miniature cubic satellite, measuring 10 cm along each edge and weighing about 1 kg. Onboard it will have a suite of 25+ sensors, including three cameras, a Geiger counter, spectrometer, magnetometer and more (check out the FAQ below for a full list). The sensors are connected to a bank of…

On this tutorial, we will show how to declare an array of arrays. Sometimes you need to dynamically choose which array to use, so it's better to have an array of arrays.
The theory is you can have an array of any type. A char array will store char values, a int array, int values, and so on. Then, you can have and char* array, which is an array of pointers to char variables. Behind the scenes, any array is a pointer to the first variable in the array. For example, an "…Continue

This volumetric display really shows a lot of potential. And it has just the right balance of simplicity and ingenuity. The rig is being developed by [Michel David] and involves a screen shaped like a helix, and a laser which shines through an optical filter disk.
The moving parts of the device are mounted on the same shaft, which is spun by a belt system…
