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).

So 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.

Broadcast live streaming video on Ustream

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.
