Processing – interface on steroids

Everyone who become interested, will, rather sooner than later, stumble on the name Processing. Processing is the software on which Arduino IDE is based. But, it isn’t the only common thing. At first – what is the Processing? It’s a programming language (under an open source license) with IDE environment created for the people involved […]

SelFly – from the space by glider

SelFly is an interesting (IMO) project of an autonomic (with autopilot) glider which will, elevated to a high altitude (about 30 km) with a weather balloon return home on its own. Good base for further experiments. All the more I was glad it’s Polish, domestic production :) . I hope the entire project will succeed. […]

Have you got any Cray soft in your drawer?

Chris Fenton, an electronics engineer living in NYC is making various DIY projects in his free time, such as notebook based on Picaxe uC (v1 and v2). These project aren’t always very sensible :), because who really needs this notebook, but have pretty high educational value. While reading article about 2-stage light gas gun (for […]

Magic glove

From time to time, in Arduino world there comes up a project, which is simply breathtaking. Everyone likes something different, but this thing is really sensible. At first glance you may think – another glove for VR or controlling some console. Not exactly… This is automatic sign language translator. Thanks to an accelerometer and flex […]

Galvanic isolation: optocouplers

For sure, you have heard the term galvanic isolation many times. In brief, it’s about separating the source of signal from the microcontroler in order to prevent it from unwanted and dangerous voltage spikes, while allowing to read the signal. Such a separation is provided by optocouplers. The optocoupler contains in common package both infrared […]

I2C in a slightly different way

In Arduino IDE there is Wire library available, supporting I2C protocol (you can read about it on Arduino pages, in irreplaceable Playground section). Todd Kurt wrote on his blog that he will make the code of a new library for I2C – SoftI2CMaster accesible through various projects related to BlinkM. How it differs from Wire? […]

Arduino Bluetooth on Ubuntu

Arduino Bluetooth – Arduino without USB port, with Bluetooth module instead. Ideal solution if wireless communication with Arduino is needed. At first – some differences to an ordinary Arduino Duemilanove. Arduino BT is based on ATmega168, so we have a little less memory at disposal. There is no USB port, so we have to power […]
