Breakout – Connect the web and the physical world

„Breakout is a prototyping tool for exploring the intersection of the web and the physical world. The popular Arduino platform and the Firmata protocol are leveraged to enable users to access physical input and output purely from javascript. This makes it easy for anyone familiar with javascript and basic web development to explore the possibilities of using physical I/O in their web applications. Furthermore, the Breakout framework includes a growing library of hardware abstractions such as buttons, leds, servo motors, accelerometers, gyros, etc enabling the user to easily interface with a range of sensors and actuators using just a few lines of javascript code.“

The author writes some books definitely worth reading !

Jaluino

Everyone heared about the Arduino for Atmel. Now it’s posible to work with the modern PIC and use a arduino like board, the Jaluino.

„JAL (Just Another Language, version 2) is an open source programming language built for programming PIC microcontrollers. If electronics is your thing, JAL is for you!“

the 1-Key-Keyboard project

„The idea for a 1-key keyboard comes from the need as an interaction designer to make “cheap, quick and dirty prototypes.” When creating a quick screen-based demo in e.g. Adobe Flash, a common way of quickly prototyping physical actions is to assign actions to certain key presses on a keyboard. In more advanced prototypes, physical hacks to the circuit board from a keyboard are also often used to interface custom buttons and switches with a computer.“

Anschluss ins Netz – AtMega32 mit Ethernet Board

Der Empfang von einigen Newslettern erweißt sich doch manchmal als sehr informativ. Gestern im Posteingang und hoffentlich bald in meinen Händen zum zusammenbauen und experimentieren, der Bausatz AVR-NEt-IO von Pollin für nur 19,95.

„Ethernet-Platine mit ATMega32 und Netzwerkcontroller ENC28J60. Die Platine verfügt über 8 digitale Ausgänge, 4 digitale und 4 ADC-Eingänge, welche alle über einen Netzwerkanschluss (TCP/IP) abgerufen bzw. geschaltet werden können.“

AVR Logic Analyzer

„In this article Frank Zhao details his project to make a Logic Analyzer with an ATMEGA168 microcontroller. This is the same microcontroller used in the popular Arduino platform so many of you should be able to make use of this project. The ATMEGA168 does the work of taking samples and works with Processing and Java to implement an nice user interface to the logic analyzer. Frank includes all the source code for both the firmware and the Processing programming language.“
