Build a Dimmer Switch for $7.25

In an effort to spread the Frugal word, I've started a YouTube Channel and will posting videos there every week or so. I realize there is a ton of similar content out there, but this is a great way to build an audience (which will take time) as well as share my own unique spin on things. The videos will be lean and to the point, sharing things that I have learned that others may want to use in their productions.

Episode 1 is a simple construction project: making an inline dimmer. These are very handy on set and are easy to build for a paltry sum. When I went to build mine (with instructions from the web), I discovered a few things I knew I had to share in more than just the blog format. Hey, what kind of filmmaker would I be if I didn't make films? Even simple ones?

Here is the Instructables version.

I'm always open to suggestions, so please comment with your feedback. I'd love to hear your opinion and/or ideas for projects you would like to see built for a frugal amount.
