I had a minor bug in Herp Derp where the original comments weren’t showing up on pages other than the first – this has been resolved.
Herp Derp for Opera available
Herp Derp – Safari support!
It looks like the Safari Developer Certificate stuff got straightened out.

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:
Daniel Shiffman’s Processing Kinect Library (he knows his stuff and has great examples on his site)
Arduino Ethernet UDP send / receive string
EMAX ES08A Servo
How it works:
- The Arduino Ethernet acquires an IP address and waits for UDP packets on a certain port.
- The machine with the Kinect sends packets to the Arduino that contain hand coordinate data.
- The Arduino then takes this data (an integer) and maps the range from 0 to 180 degrees.
- The mapped value is sent to the servo.

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