Hi, this is my first instructable and I hope to do more. This project was for ‘Creative Electronics’, a Beng Electronics Engineering 4th year module at the University of Málaga, School of Telecommunications. http://www.etsit.uma.es/ It’s a cnc using Arduino UNO R3 , GCode Sender and GRBL. The cnc is made of wood thanks to the […]
Hamburg Maker Meeting 2012, which took place last week and involved about 200 visitors and more than 20 exhibitors, has been a fantastic opportunity to meet and share experience regarding several topics, such as 3D printing, hacking, retro gaming and so on. At the Attraktor Makerspace, several projects have been presented and demonstrated by their

I needed a small, fast and reliable multi-voltage level translator (mainly for connecting ESP8266 boards to the Arduino, got tired of resistor networks pretty quickly) so I built a breakout board for TI’s LSF0204(D). Datasheet and info here. The LSF0204 is a nice little chip. It can translate up to 4 signals to and from the
LSF0204 breakout board: a bidirectional, multi-voltage level converter! Continue Reading
Come sapete stiamo portando un workshop di Arduino in giro per l’Italia. Siamo stati a Roma un po’ di tempo fa e ora é il turno di Matera. Sviluppo Basilicata, oltre ad avere sistemato parte dei Sassi trasformandoli in un incubatore di impresa, si é spesa per rendere il workshop possibile (avete capito bene, il

“Part Fill” Valve? Yes, Part Fill valves are widely used in Rainwater tanks. The valve will open once the water level in the tank has fallen to a low position, this allows the town mains water to enter the tank and, when the water level reaches the minimum level, the valve closes. This arrangement is
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.
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
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
Sub-picoamp input op-amp offers high gain bandwidth Continue Reading
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
Motor control is becoming the power industry’s fastest changing technology area. The reason for this is the requirement to improve energy efficiency from the millions of motors which are used in our homes, factories and cars. New developments in motor controller design, current sensing and control algorithms will be needed if new and more stringent
New energy efficiency rules will change motor control design Continue Reading
