Friday Post: 3D Printing and Raspberry Pi live streaming

Hey All,

Happy Friday and happy 4th of July weekend!

On Monday I recieved a 3D Printer from the company M3D.  It is the blue Micro 3D printer.  If you use the coupon code “refurb” you can get one for $300 dollars (plus about $12 shipping).

microBlueSo far I’ve printed out a bunch of things, ranging from Bulbasaurs, and Ford Fiesta ST scale models, to characters from Dota and keychains.  So far it has been an awesome little printer.  Now, it’s slow, a little loud, and only has a print size of 6x6x6, but that hasn’t been an issue yet.

I’m using a Raspberry Pi with the camera module to livestream my printer.

Livestreaming from USTREAM on the Raspberry Pi

Here is a quick guide to livestreaming on the Raspberry Pi with USTREAM and an RPI Camera Module

  • Install Raspbian to your Raspberry Pi SD Card
  • Install the Raspberry Pi Camera Module
  • Using Raspi-Config activate the camera module
    • sudo raspi-config
    • Enable Camera
  • You are going to need a version of ffmpeg installed.  The version from apt-get will not work.
    • You can download a working binary here: http://files.oz9aec.net/datv/490-rpi-hdtv/ffmpeg
      • wget http://files.oz9aec.net/datv/490-rpi-hdtv/ffmpeg
      • chmod +x ffmpeg
    • Or you can download and compile the ffmpeg sources via git
      • git clone git://source.ffmpeg.org/ffmpeg.git ffmpeg
      • cd ffmpeg
      • ./configure
      • make
      • sudo make install
  • Set up a ustream script:
    • nano ustream
    •  #!/bin/bash
      RTMP_URL=<rtmpurl>
      STREAM_KEY=<streamkey>
      while :
      do
          raspivid -n -vf -hf -t 0 -w 960 -h 540 -fps 25 -b 500000 -o - | ./ffmpeg -i - -vcodec copy -an -metadata title="Streaming from raspberry pi camera" -f flv $RTMP_URL/$STREAM_KEY
          sleep 2
      done
    • Change RTMP_URL and STREAM_KEY to match the keys you get from your USTREAM Channel settings page.
    • If you compiled and installed your own version of ffmpeg, remove the ./ffmpeg and replace it with just ffmpeg in the code above.
    • chmod +x ustream
    • ./ustream
  • With any luck, you will now be streaming to your USTREAM channel.

  1. Thanks for the heads up. I ordered one, had to get it in orange to go with your blue for a Gator theme. Would love any comments you have along the way that can help. Gameboy case for piplay is one of the first big prints I purchased it for.
