Install and update software listed above. Be sure to have the pifm folder inside your home directory (typically /home/pi/pifm). Save the RaspWristRadio Python Script to your home directory. Make sure the script is executable: chmod +x radio-wearable.py To have the script work without editing, create a folder named music in the ~/pifm folder (typically /home/pi/pifm/music) and copy your WAV audio files into that folder. Set the script to run on boot by adding sudo python /home/pi/radio-wearable.py & to /etc/rc.local with a text edit like nano. Reboot the Pi and the system should be up and running as seen on the video.
If you have your WAV’s in another folder you and edit the script and change the path to that folder on this line – for root, dirs, files in os.walk(“/home/pi/pifm/music”):

Adafruit Blue&White 16×2 LCD+Keypad Kit for Raspberry Pi: This new Adafruit Pi Plate makes it easy to use a blue and white 16×2 Character LCD. We really like the 16×2 Character LCDs we stock in the shop. Unfortunately, these LCDs do require quite a few digital pins, 6 to control the LCD and then another 1 to control the backlight for a total of 7 pins. That’s nearly all the GPIO available on a Pi!
With this in mind, we wanted to make it easier for people to get these LCD into their projects so we devised a Pi plate that lets you control a 16×2 Character LCD, up to 3 backlight pins AND 5 keypad pins using only the two I2C pins on the R-Pi! The best part is you don’t really lose those two pins either, since you can stick i2c-based sensors, RTCs, etc and have them share the I2C bus. This is a super slick way to add a display without all the wiring hassle. Read more.
PowerBoost 500 Charger – Rechargeable 5V Lipo USB Boost @ 500mA+: PowerBoost 500C is the perfect power supply for your portable project! With a built-in battery charger circuit, you’ll be able to keep your project running even while recharging the battery! This little DC/DC boost converter module can be powered by any 3.7V LiIon/LiPoly battery, and convert the battery output to 5.2V DC for running your 5V projects. Read more.
