Robot36 encoded SSTV image, sent by an Arduino w/ Audio Shield

For an amateur radio project, I coded up a simple encoder for Robot36 format SSTV images, and generated a .WAV file. I then loaded this file onto an SD Card and plugged it into an Arduino which is equipped with an Audio Shield. I piped the audio output of the Arduino back into my laptop, which is equipped with Multiscan, a good SSTV program for Mac OS X. As you can see, the timing isn't very close: the image skews rather sharply to the right, but in the end, the image is automatically corrected by Multiscan.

@iPixzel You can use this, i have all my radio stuff in there msstv is in there for encoding images multiupload [dot] com / M1S70UDBQF

Anyone know how to encode SSTV signals. I want to make my own

whats the sound

Hello i was wondering how did you do this? im tring to do the same thing over HAM RADIO

When I used Multiscan on my mac, I loaded a picture into it, and started it, but it made a huge boom noise that was very loud and blew out my speakers until i reset my computer. what should I do to make it work? It produced the image sound fine.

Very nice project, great to see experiments like this with the arduino
