Indoor/outdoor wireless thermometer using Arduino

This Arduino-based wireless thermometer uses two Arduino boards to measure indoor and outdoor temperatures. The outdoor Arduino board sends out the outdoor temperature measured by DS18B20 sensor to the indoor Arduino board using inexpensive 433MHz RF transmitter and receiver modules. The indoor Arduino board then displays the indoor and outdoor temperatures on a character LCD display.

BrickPi Bookreader version 2 can read a real book

BrickPi Bookreader 2 is a new version of BrickPi Bookreader and is capable to read aloud a real book and also to turn the pages of the book. The page turning mechanism is accomplished two EV3 motors, and a LEGO wheel. The Raspberry Pi takes a picture of each page and converts it to text and then speaks it aloud through speakers. When the page is done, it is flipped over to continue to a new page.
