The tricorder is loaded with a lot of useful sensors
The Raspberry Pi has proven to be an amazing device, but some users have taken it to whole new levels.Recantha, a known developer in the Raspberry Pi community, has managed to use the mini PC in an entirely unique way. He himself built a working tricorder, inspired by the devices in Start Trek.
He used some sensors, two for temperature and one each for magnetism and distance, a simple LCD display, switches, a light-resistant resistor, a thermistor and an Arduino Leonardo clone. All of these were enclosed in a Lego case. A camera might be added later.
Raspberry Pi relies on an ARM processor with a clock speed of 700 MHz, 512 MB of RAM, an SD card slot and a 5V Micro USB connector that supplies the power. It also features RCA and HDMI ports.
