The circuit is a homemade ISP using an ATmega8 with USB communication and software that allows to program AVR microcontrollers more (ATmega, ATiny) to be used as Arduino, an eco-mode. It is good to always have a backup programmer as a plan B The schematic and firmware can be seen here. Below are pictures of the experience. […]
In Barometric Sensor Ethershield
This is a preliminary test of a barometric sensor connected to an Arduino board with homemade ENC28j60, that allows you to read the atmospheric pressure in real time using I2C in PA (Pascal) from the point where. It also makes reading of temperature. Is a strong candidate to get in several projects intended for meteorology home. […]
Nokia LCD 3510 Interface with PIC18F
When a mobile phone stops working in terms of software and even some hardware there are parts that can be used for experiments or projects, in particular the LCD's, saving yourself some money. The aim is to use an LCD from a Nokia 3510 connected to a microcontroller for information visualization, as done in a […]
Homemade Arduino with ENC28J60
After I complain of my Arduino Duemilenove due to lack of current to power other devices, I decided to build my own in perforated plate, with a 20 MHz crystal, an LM317 1A and a bus to connect ENC28J60. The part belonging to the Arduino occupies as much or less than the original PCB. Below is the part of the Arduino to function in full, with […]

Pinguino Project test
Created from the first draft PIC18F4520 Microchip (MultiEth), was changed to be compatible with the PIC18F4550 pinguino minimum.
Arduino DS18B20 1Wire
The idea arose as a means to verify that the temperature of a room was correct before a Mercury thermometer. Arranged an alphanumeric LCD 20×4 characters, a damaged FAX , but luckily the LCD was OK and there were some samples of 1Wire temperature sensors. The objective would therefore be to visualize temperature information […]
Arduino na TV
In General, When we want to display information from the Arduino, such as a temperature sensor, We usually use a serial Terminal, because of the ease in obtaining this. Another way to view this, home with something more, It would be with the LCD, but are somewhat expensive. Then with some research, faced with this site, allowing to display information in a […]
Android development – First Steps
Development on Android platform, using the SDK , Eclipse with its plugin and results on a emulated machine and other real, being this a Samsung 550 with Android 2.1.
Liquiduino Shield for Arduino
Here's a shield called Liquiduino, to monitor liquid levels, using sensors (buoys) resistive bridges in order of 0 the 220 Ohms. Has an input and an output event for interaction. The prototype is as follows: It also has a RTC and an EEPROM to register for timed events of variations resulting from the measurement of liquids. It is still about […]
