SAN MATEO, Calif. – Massimo Banzi launched a $69 board that aims to plug do-it-yourself-ers into the cloud. The Yun is the first of a family of low cost, low power Arduino cards that run Linux and Wi-Fi, surfing the trend toward the Internet of Things. Yun, named for the Chinese word for cloud, aims …
Currently revising the design to reduce weight and have bigger wing chord base on advise from DIY drones with slightly shorter wings. AUW 1521 Grams Wing loading 14.83 oz/ft² power to weight 270 Watts per Kg should perform much better than Yellow plane one. I’m changing from the D4023-850 Out Runner Motor to a higher kv TurnigyL3010C-1300kv Tests show significant improvement in static thrust …

By: Alex Danovich, President San Francisco Circuits We live in an exciting time where we see a resurgence in electronics as a hobby. Mass production has wiped out a generation or two of kids learning to build radios from scratch with their mom or dad. In the good old days, not sure when, you had …
In the last part of my tutorial about the A4988 driver, I’m going to explain how to build a controller to adjust speed and rotation direction of a stepper motor. Schematics I used the same setup introduced in a previous post: an Arduino Uno; a LCD Keypad shield; a Pololu A4988 driver mounted on a breadboard; a NEMA17 stepper …
Ci aspetta un week end intenso: mentre Davide e Pitusso tengono il workshop base di Arduino a Matera, a Venezia (presso H-farm ) si tiene il secondo codemotion di quest’anno, che vedrà il nostro Cristian Maglie raccontare l’Arduino Due e il cammino che abbiamo intrapreso per realizzarla. Arduino sponsorizza anche l’Hackaton sulle emergenze, offrendo 10 Arduino …

This Arduino based autonomous robot is named « Line Follower Organ », « Orgue Suiveur de Ligne » in its maiden language. What’s new with this instrument is that it moves along its partition in order to play …
Brazo robot dibujante V2. (Monstruosidad tecnológica) Los resultados del brazo robot dibujante anterior no tuvieron una gran resolución. Mi idea inicial era hacer que pudiera escribir y eso resultaba impossible. Esto se debía principal mente a que cada paso de los motores paso a paso que uso es de 0.9° (400 pasos / rev). Cada …
