DENVER TAC 70072 Firmware

August 31st, 2014 by Miguel Ferreira | In: Android

It's been over a year since the last time here was added some kind of content, but when there's nothing interesting you might as well not get garbage…

This time I'm publishing here the original firmware to a tablet Denver TAC 70072

  • 7 “800×480 (16: 9)
  • 1.2 GHz CPU
  • 1GB of memory DDR3 RAM
  • 8GB of internal memory + micro card slot SD
  • Wi-Fi 802.11 b/g/n
  • Front camera (0.3mpixel)

A bit of history:

I bought this tablet to a friend out of curiosity and for being extremely cheap (It has 1GB of ram 🙂 ) and, After a few games I was with a brick, After much search, nothing… Original Firmware did not exist anywhere, I asked the manufacturer and they sent, but I had a problem – It did not work the WIFI 🙁 . I managed to find a kernel hammered that worked and walked a while to notice that had ceased to have camara… I decided to again upset the brand and this time they sent the correct firmware and everything works beautifully.

In Barometric Sensor Ethershield

February 13th, 2012 by Fábio Souza | In: 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.

Nokia LCD 3510 Interface with PIC18F

October 3rd, 2011 by Fábio Souza | In: Arduino, Electronics, PIC, Programming

When a mobile phone crashes in terms of software and even some hardware There are parts that can be used for experiments or for 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 previous experience, in a Nokia LCD 1100.

It is assumed that this controller is prepared both for the LCD 3510 ( screen with shades of gray), as well as the 3510i (the colors), According to this site.

Look for the welds made in contacts. It is a meticulous and work something that quite calm, as well as a low-power iron (14W) so as not to damage the contacts and the plastic membrane.

Homemade Arduino with ENC28J60

September 7th, 2011 by Fábio Souza | 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, 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 a FTDI USB to RS232 and external power supply.
