[edit] Barometric pressure and temperature sensor

http://learn.adafruit.com/using-the-bmp085-with-raspberry-pi/overview

The BMP085 sensor is about 50 m above sea level. The Wunderground data is from a weather station at an airport nearby.

[edit] Motion sensor

HW used: https://www.sparkfun.com/products/8630

WARNINGS:

The colors of the wires can vary greatly. Looking at the unit from the top, the middle wire is ground, the left-most wire is the alarm, and the right-most is the power.

You have to solder a new wire to the L78L05 (http://www.fairchildsemi.com/ds/LM/LM78L05A.pdf; SOT-89) voltage regulator’s output or remove the regulator entirely and bridge the input pad to the output pad if you are driving the sensor with 5V.

The GPIO pins are NOT 5V tolerant and are NOT over-voltage protected. You have to reduce the PIR alarm voltage to 3.3V.

[edit] Squeezebox

Requirements: Logitech Media Server

Install squeezelite (http://www.raspberrypi.org/phpBB3/viewtopic.php?f=38&t=25778).

Start squeezelite:

./squeezelite-armv6hf -o hw:CARD=<card> -m <client MAC address> -n <client name> <LMS IP address>

Please note that the 'hw:' prefix is required for Google TTS (16 kHz mono mp3) to work.

Test the installation:

telnet <LMS ip address> 9090
<client MAC address> playlist play http://translate.google.com/translate_tts?tl=en&q=Test
