LittlePrinter: Unterschied zwischen den Versionen

A few years ago a design company from London called "berg" introduced the Little Printer. The device basically is a small printer that prints various feeds provided by berg on a daily basis. Feeds like twitter, newspaper articles, trivia and sudoku. For that it uses regular receipt paper. ([https://www.youtube.com/watch?v=B_bytm9_P4w promo video])

 

In 2015 the company went into hibernation but kept the servers running for the rest of the year. Now, in January 2016 the devices are practically useless without the backend servers. I got mine dirt cheap on ebay. [[Benutzer:HKay|HKay]] ([[Benutzer Diskussion:HKay|Diskussion]])

 

The printer does not talk to the internet directly. That's what the extra box called "bridge" is for. It has a RJ45 connector for Ethernet and a ZigBee module.

To connect to the board via a serial link I used the "SparkFun FTDI Basic Breakout". The RX,TX and ground pins are indicated in the picture above. Connect "RX"(receive pin) to the "TX"(transmit) pin on the FTDI board and the other way around. Also connect GND to GND. Make sure you have the 3.3V version as the 5V version would likely fry the board.

 

Here is the boot chatter of the bridge.

The system is a AT91SAM9G20 at a clockspeed of 396 MHz running Linux with a kernel version of 2.6.36.4 in April of 2013
