Today I am writing you because I was short on dimmers and you inspired me to build one. I started watching your videos chronologically, and that was the first one. So I went out and got the parts for the dimmer as well as some random PVC pipes and parts that I thought I should practice with.
Attached are a few pictures of the dimmer I built. I added a few very simple improvements, that I think are worth adding perhaps to the comments of that video page.
