LIVE DEMO

How does it work?

  • YouTube API search bot

  • On play, video is streamed off YouTube.

    • ffmpeg separates the video/audio streams

    • Final mp3 stream is streamed as a "waiting audio" file back to the phone

Complications & Things

  • YouTube is not a music site

  • ffmpeg is not made for real-time streaming

  • Twilio charges by the minute

Web over SMS

Untitled project to surf the web over SMS.

Screenshots

Incomplete!

How does it work?

  • HTTP server running on Android

  • Traffic is rerouted to localhost

  • Server runs a tunnel via Twilio to a VPS

    • VPS connects tunnel to HTTP client, and executes the request

    • Response is tunnelled back

  • Response is pushed into WebView

Complications & Things

  • SMS messages are capped to a 135 character limit

  • SMS messages are not ordered

  • Carriers place a limit of 250 automated messages per day

  • SLOW
