How to (programmatically) download a file with IOS (iPhone, iPad)
One of the most frequently asked features, when I develop iphone apps for my customers, is the download of files from a ftp server. Really I can do a full protocol implementation, but it's to expensive. Instead, while I... Read more
How to economize the used pins to manage bicolor leds on arduino (or other MCUs)
Yeah, sometimes the signals you can handle with Arduino (or others MCU) are not enough. But if you are using a bicolor led to see two different states of your system, you can play the following hack. This is... Read more
gigino: a low cost prototyping board based on the Arduino project
Finally the first release of "gigino", our low cost Arduino prototyping board, is out. Gigino is based on an ATMEGA328P-PU microcontroller produced by ATMEL. Really it isn't a mounted board, it is a kit. So you can take the... Read more
How to fade in/out a bicolor led using arduino (pwm)
First of all a few theory Bi-colour leds. A bi-colour LED has two LEDs wired in 'inverse parallel' (one forwards, one backwards) combined in one package with two leads. Only one of the LEDs can be lit at one... Read more A new developer board based on PIC18f27j53
In April 2011 I wrote about the PIC18F27J53 describing it like a monster for its capabilities, and I promise to build a development board with it. And now this board is here!!! The Pic18f27J53 has the following features: ... Read more
Our RM2012 (temperature and humidity sensor) has a great bug, we are going to solve it in a while.

Building a custom kernel is one of the most important rites of passage for advanced Unices users. This process, while time consuming, will provide many benefits to your system. Unlike the GENERIC kernel, which must support a wide range... Read more
A pseudo serial sniffer for RS232 communications
All electronic devices, computers and micro controllers need to exchange data with other devices. One of the most used way, since 1969, is the serial transmission using the RS232 standard when the EIA defined it. Serial transmission is commonly... Read more
How to select odd (or even ) raws from a text file using the bash
Yesterday I had to select some raws (1, 5, 9, ….) from a text file. This has been a hard job because I was trying to solve the wrong problem…… Really, before coding you should analyze deeply your problem... Read more
