Herp Derp updated

I got around to fixing some annoying bugs in Herp Derp tonight:

  • When loaded via HTTP Secure (HTTPS) Herp Derp now works (thanks for reminding me @Funshine__Bear)
  • Firefox no longer freaks out when there is only one comment
  • YouTube Feather Mode is now supported (thanks @_sjs)

The latest version is available for all browsers and can be downloaded here.

 

Kinect + Arduino

With an Arduino Ethernet, Processing, and a Kinect, I was able to easily create this little demo where hand movement can control a servo. This is just a tiny step in my master plan to create a robot clone so that I don’t have to leave my chair.

The following libraries and drivers made this work and also made it super easy for me to create it:

OpenKinect
Daniel Shiffman’s Processing Kinect Library (he knows his stuff and has great examples on his site)
Arduino Ethernet UDP send / receive string

Servo:
EMAX ES08A Servo

How it works:

  1. The Arduino Ethernet acquires an IP address and waits for UDP packets on a certain port.
  2. The machine with the Kinect sends packets to the Arduino that contain hand coordinate data.
  3. The Arduino then takes this data (an integer) and maps the range from 0 to 180 degrees.
  4. The mapped value is sent to the servo.

Arduino’d Gingerbread House

It’s not a serious competition until you’ve put a microcontroller inside your gingerbread house. Since we were going for the Charlie Brown theme, I ripped apart and adapted a musical card that played ‘Linus and Lucy’. I also rigged up some LEDs to blink with the music. Video below the pictures.

Ubuntu and PCMCIA card

After installing Ubuntu Server 10.04 LTS on an old laptop (don’t ask why) I found that it wouldn’t detect its PCMCIA wired Ethernet card (PCM100).

Solution:

  1. Copy over the packages pcmciautils and libsysfs2 (I had to download them and transfer via USB flash drive: pcmciautils, libsysfs2)
  2. Install the packages: sudo dpkg -i [name].deb
  3. Reboot

VoilĂ !
