“It is a very simple data logger project based on PIC12F683 microcontroller. The microcontroller reads temperature values from a temperature sensor on a regular interval basis and stores them into its internal EEPROM memory. The recorded temperatures can be later transferred to a PC through serial interface.”

“Tatiana Plakhova is a Moscow based designer and the art director at Moscollective design studio. Her art is deeply inspired by complex patterns found in fractals or biological organisms. Instead of using algorithms to generate the images, she creates everything manually. This also indicates that, although a lot of her works look like visualizations, none of them are based on real data.”

“Fame in the aerospace industry has been typically reserved for the people who pilot flying machines — Charles Lindbergh, Amelia Earhart, Chuck Yeager, Neil Armstrong. Not so much for the people who design the technology.

Maverick aeronautical engineer Burt Rutan may be an exception.”
