Anche quest’anno Arduino partecipa a Robotica – mentre non partecipa Makersitaly! – e ha scelto il mezzo della stampante termica in controtendenza con i mille volantini, flyer, cataloghi, allegati, biglietti da visita e tutta la montagna di carta che avrete nelle tasche alla fine dei tre giorni – giovedì venerdì e sabato – della manifestazione.

Step 1: Check the materials you need. Below is the list of stuff you need to make it: 1. Arduino I used an Arduino Pro Mini 3.3V. You also need USB-Serial tether to program it. 2. A battery box I used a AA x 4 battery box with power line wires. 3. Breadborad I used […]

I came across these Force Sensitive Resistors. I like them a lot and I wanted to do something with them, may be making them more usesable than standing on the breadboard. Few months ago, I created the pocket-sized  RevIO – Arduino Compatible and having fun with it since then. While playing with these two, I decided […]

Analog channels A2 to A5 on an Arduino Uno are used to measure four different voltages. The measured voltages are displayed on a 16 character by 2 line LCD. The four channel Arduino multimeter can measure four independent DC voltages that can each be in the range of 0 to 50V. Voltages are displayed with […]

As per an assignment in my digital multi-media class, I’ve combined two Arduino-related tutorials into a functional object! The result is a pair of infinity mirrors that flash red and blue depending on minute fluctuations in ambient temperature. This is my first experience with Arduino, and my first attempt at building an electronic device from […]

Linear Tech is aiming at high-impedance sensor transimpedance amplifiers with an op-amp that requires only 3fA of bias current (typical at 25°C) while offering 500MHz gain bandwidth product. Potential applications for the chip, called LTC6268, include interfacing ADCs to reverse leakage (linear) mode photodiodes. 20kΩ transimpedance gain is available at 65MHz, and 499kΩ with 11MHz […]

************************************************************************** Major updates – A much better enclosure for this clock has been designed – check out http://www.instructables.com/id/The-Wordclock-Grew-Up/ ************************************************************************** Last month I wanted to build a special gift for my beautiful wife, Megan.  She has a teaching background in English, so what better present to make for her than a clock that uses language to […]

The games market may well dwarf the music and movie industries combined in global revenue and new-release games offer lighting effects and texture detail that make you forget you’re in a game and not a movie. But there’s always something that tugs us back to retro gaming – the blocky graphics corny 8-bit sound and […]

I have a “through the Looking Glasses” idea of making another version of  Palm Arduino. Since this design derived from Palm Arduino, I will called it Palm Arduino II. This Palm Arduino, the Second, will be the combination of Palm Arduino and Portable 5V Voltage Regulator. So that everything is staying together closely in the same package! […]

I frequent a blog called hackaday.com which featured a project by “Nikolai”, it was a 10cm LED ball that used shift registers. It seems like a really fun project to attempt but the cost of having the boards made & not having any experience sending eagle drawings to fab shops initially kept me from starting.  […]
