Power supply – LM317

May 24th, 2012 by Miguel Ferreira [Electronics]

I received a contact of a player because of the lack of schema source/charger, so I decided to write a little…

The basic scheme is as follows:

USBasp ISP with ATmega8

April 27th, 2012 by Fábio Souza [Arduino, ATMEGA, ATMEL, Electronics]

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 scheduler as plan B

The schematic and firmware can be observed here. Below are pictures of the experience.

And here's a reading to an Arduino with an ATmega 328:

ATMEGA328 … parte 2

March 29th, 2012 by Miguel Ferreira [ATMEGA, ATMEL, Blog, Electronics]

Today I decided I had time, and after reading something more (http://mightyohm.com/blog/products/hv-rescue-shield-2-x/) did on Board of experiences to see if my beautiful atmega was returning to hear me….

True low cost arduino

February 19th, 2012 by Miguel Ferreira [Arduino]

With half a dozen euros is an arduino, stable and functional.
Bill of material:
– 1 ATMEGA328p
– 1 16 MHz Xtal
– 1 USB2Serie
Some hard wire
Uma placa branca de experiências e está tudo 🙂
Didn't have the exact value of account that this cost me, but plan to add these pieces all as a kit to sell, the low-cost course.

Soon I'll post more about this topic.

In Barometric Sensor Ethershield

February 13th, 2012 by Fábio Souza [Arduino, Arduino, ATMEGA, ATMEL, Electronics, Intranet and Internet, Programming]

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.

Thomson Keys – UPDATE

February 13th, 2012 by Miguel Ferreira [Meo Hack]

Recently traded a few emails with a person who showed me some information at least interesting:

Good! Was to warn that there already exists a tool able to exploit the vulnerability. More info here: http://ptsec.info/forum/showthread.php?21-Vulnerabilidade-que-afecta-Thomson-com-WPS-implementado (have to be registered in order to be able to see the forum topic) or here (in English): http://www.backtrack-linux.org/forums/showthread.php?t=47519&p=213572&viewfull=1#post213572
Cumprimentos

I have not had time to read everything and test, but information-crossing is an interesting topic.

New Server / News

January 23rd, 2012 by Miguel Ferreira [Blog]

I'm testing new server (paid by me) for this website and a few other projects, faster, more space and, without doubt much more expensive.

In recent days I finished another phase in the development of meteorological stations, each time they are more complete and complex and to operate with fewer problems (in view of the lack of development of €, is running fine) Soon I will write an article about them…

If anyone is interested in relieving myself from this server costs, who me contact, in return I offer space for site host
