Atmega1284P Bigboard

Then name might not sound imaginative at all, but it’s a well featured ARDUINO compatible board, only the hardware, and is based on the ATMEGA1284P by ATMEL Corporation. It’s a small footprint PCB (49.5 x 37mm) and can be programmed to collect and post data to an internet logging site such as thingspeak.com or Xively. The use of a Wiz820 Ethernet module allows the Ethernet to be powered-down when not in use, only becoming active when data is to be sent in for logging. Extra hardware on the board makes it particularly useful for a compact stand-alone logger and data gatherer. It even features a flexible power option of both 5V and 3.3V, as things like SD card, Ethernet works on 3.3 V. The Wiznet module has the RST (reset) and PD (power-down) pins connected so low power Ethernet is available by wake-up-and-do-something type programming, and the Ethernet interface can be fully reset without resetting the board. Programming can be by the standard AVR 6-pin programming header, or if an Arduino bootloader is installed, by using a FTDI-basic serial programmer. Continue reading

The Bizarre Yet Fun Hacklab Toilet

You’re a loyal Twitter fan and you couldn’t get enough with it? Although it might sounds a little bit crazy, but some of the people really don’t want to miss even a single chat/message on the Twitter! If they’re given the choice, they will probably Twittering, even they’re inside toilet. Well, if you don’t mind and would like to post to Twitter in toilet, then this Hacklab Toilet is the idea device that you must equip on your toilet! Here’s how the Hacklab Toilet concept: Every time, when you’re flushing the toilet, it will post a message to Twitter automatically. For making this Hacklab Toilet, you need the following components: An Arduino Duemilanove, An Adafruit Ethernet shield, WIZnet Ethernet module, Mercury switch, Perfboard, Wires, Cables and so on. Ok, first of all, you have to assemble the Arduino Ethernet and the WIZnet module. Just plug in to it, then attaches them to the arduino. As you can see on the below figure, the arduino is wired to the wall complete with power and Ethernet. After it, you must use a… Continue reading
