The air around you is full of data from medical devices, smart home devices, airplanes, cars, phones up to radio & television. rad1o may help you to access them.

If you really do not know what to do with your rad1o, please consider donating it to your local hackspace!

Goto howto: to see step-by-step instructions for common tasks like updating the firmware.

Learn more from the people who brought you rad1o (and others)!

Images and animations should be 130px x 130px.

Hold joystick UP when booting to mount USB. Drop files in .an1 or .lcd format to have them show up in the image menu on the default firmware.

To convert images, use the perl scripts from the f1rmware/tools directory in the GitHub repository.

(the perl script depend on libgd (libgd-graph-perl in debian))

Example usage:

~/src/f1rmware/tools $  ./img2lcd.pl ../assets/cat.png
~/src/f1rmware/tools $  ./img2lcd.pl ../assets/cat2.png
~/src/f1rmware/tools $  ./lcd2ani.pl -v ../assets/cat.an1 ../assets/cat.lcd 200 ../assets/cat2.lcd 200
Adding ../assets/cat.lcd for 200 ms
Adding ../assets/cat2.lcd for 200 ms

osmocom_fft (may require the installation of gr-osmosdr) Should display sth. like:

ADS-B is a positioning system for planes. See Wikipedia. For GNU Radio exists the module gr-air-modes which contains the command line tool modes_rx which can be used to receive ADS-B data. sudo apt-get install gr-air-modes

modes_rx -s osmocom -d

• Requires GNURadio
• Requires either an extra antenna or pressing a finger on the upper right corner where the antenna is usually soldered (then you are a human antenna )
• Example Script: FM Radio Example (must be opened with GNU Radio Companion)
• The script can be started via the arrow in the middle of the menu
• Depending on your SoundCard and your CPU you may vary the parameters for samp_rate (eg. decreasing to 2M) and audio_samp_rate(eg. increasing to 96k)
• The Frequency can be adjusted via the FFT Plot that opens when the script is started

• Can be illegal depending on which frequency you broadcast: check the local laws
• Requires GNURadio
• Requires either an extra antenna or pressing a finger on the upper right corner where the antenna is usually soldered (then you are a human antenna )
• Example Script: FM Broadcast Example (must be opened with GNU Radio Companion)
• The script can be started via the arrow in the middle of the menu
• It uses a fifo (create it with mkfifo and change the File Source box in GNU Radio Companion accordingly). You can feed it with mp3 by executing, for example: mpg123 -r41000 -s foo.mp3 > /path/to/input_fifo. You can change the broadcast frequency by modifying the osmocom Sink configuration in GNU Radio Companion.
