All Asia Timelapse Twvee

February 18, 2011

Just installed a new timelapse twvee set at All Asia Cafe in Cambridge MA.
Each day it makes a audio and video timelapse movie.

youtube channel=http://youtube.com/allasiatwvee

The scripts are similar to those used in the Timelapse memory server. It also has an audio component which is similar to the methods described in this post.

The machine is an old hp pc(~$140 from craigslist) with ubuntu 10.10 (free if you don’t count internet to download and cd to burn it on) on it. Webcam is a playstation 2 eyecam(~$40). I spent some money on lumber to build a box around it but mostly used scraps.

Files:
AVcapture.sh https://gist.github.com/834255
audiocombine.sh https://gist.github.com/834248
videoloop.sh

The machine also uses the youtube uploader stuff described in this post.

A twvee(twee-vee) set is sort of like a tv set except that it’s 2 directional. Maybe it should be a 2V set?

UPDATE:
using motion now to capture frames. other incomplete notes here

update2:
a related experiment from a machine shop. some more theory too.
