My Homemade Arduino

September 16th, 2011 by Miguel Ferreira | No comment | In Arduino, ATMEGA, ATMEL, Blog

As my old arduino was sold (for wine or for something useful), I decided to do a 100% compatible but without the bugs that I had…

As “hack” a a ‘Air Wick’

September 16th, 2011 by Miguel Ferreira | No comment | In Home

As we all television, We often bombarded with advertisements on the Air Wick, an auto Fragrance Diffuser….

I will explain how to save some cash, because each original recharge costs about € 4 (at best).

It is with some sadness that were identified here this program, because it was done at the request of a person in vworker, but due to some problems… Here is the program for those who want to see, use and modify.

Homemade Arduino with ENC28J60

September 7th, 2011 by Fábio Souza | No comment | In Arduino, Arduino, ATMEGA, ATMEL, Blog, Electronics, Intranet and Internet, Programming

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, a       and an LM317 1A 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 a FTDI USB RS232 Board   and the external power.

Nokia LCD PIC18F2520

August 5th, 2011 by Fábio Souza | No comment | In Blog, Electronics, PIC

From a nokia 1100   damaged    , but with functional   LCD  , It used a   to make the display PIC18F2520 text and variables, as the temperature. Since the communication with the LCD is slow and series, It used the internal 8 MHz crystal to command the screen by PIC.

 

The     screen   seems   and transparent has a low    (10mA), same with brightness.   With this, You can reuse functional screens of mobile phones that were cancelled.

The main   are routines in this  site, having been changed to the PIC above.

Donations… Need-if!

August 4th, 2011 by Miguel Ferreira | No comment | In Blog

Unfortunately in this day and age everyone asks for donations, even without that depend on them, This is not the case.

This site is ‘hostado’ in 13StudioHost,Once again I thank them by great favor that make me, but also for the good service that has (administer other sites on their servers and tastes great).

Returning to the subject… As you all know to keep a site it costs some money and without support is complicated, as I must have repaired, I have been testing some ads to see how much they were paying… The end of the day on 10 years must offer to pay for a year of field. So I would ask for some readers to make a generous donation, If they are owners of a site, a blog or a company I would be happy to post here a link, or offer some of my time in services.

I accept donations by PayPal or Bank Transfer (for this please contact me).


Thank you for the time and by donations.

USBtinyISP AVR Atmel

An excellent way to reprogram Arduinos, among others…

Already bought a few months valiant this programmer, It costs about 15 €, Although you can find between 10 and 40, but decided to purchase where trust and, the past two weeks came, everything ok and functional, the first test I did was with my ‘old’ Arduino UNO (We have already dispatched for some time).

Meteorological Station (Arduino ATMEGA328)

June 29th, 2011 by Miguel Ferreira | No comment | In Arduino, Arduino, Blog, Electronics, Programming, projects

Since some time I have been to develop a meteorological station for the Free Flight Club of Caramulo with an Internet connection to update in real time….

Arduino + ENC28J60 - Estação Meteo de testesThis spaghetti of wires is only one Arduino (changed to 20 MHz) with a network card based on chip ENC28J60 (better than Wiz official), is so linked only to tests of UPTIME and reliability. So far has an uptime of about 2 months and, taking into account that my cat engraçou with temperature sensor…

The first version I made this station is based on the Arduino UNO with the official network adapter (The Wiz between 25 and 50 euros) – A huge waste of money, the second is based on the same in the arduino but this time with a much cheaper (between 14 the 30 euros) and witheurosoubt much more reliable

Now, I am trying to remove all of the potential problems that can happen to me – that being said the main source of problems is the own arduino… Result: use the ATMEGA328 for its ease of programming and information quantity, but on a plate made by me, thus reducing costs and making the project a lot more functional.

Arduino DS18B20 1Wire

April 25th, 2011 by Fábio Souza | No comment | In Arduino, Blog, Electronics

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   some samples were obtained from 1Wire temperature sensors. The aim would therefore show LCD temperature information.

This was the result obtained, using the Arduino libraries :
