  1. I have a weird error with my podcast client. The first video tutorial in this series of two is showing up as THIS episode. By clicking marked as played on it, it marks this episode as played. Playing either two gives me this part. This keeps happening with my podcasts from you. :/ Any idea what the error might be?

  2. I figured out what the problem was. You have links to two seperate shows in one post, and my podcatcher is only downloading Part one, which it had already downloaded in a seperate post, so its showing up as the same download. I can watch part two here.

  3. I was curious (approx) how long that 9V battery might last if it were switched on continuously? Hours, days, months?
    Thanks for posting.

    (note: If this double posts, I had a problem again where after I hit the submit button, I got an error that said something like “the text is wrong”. and had to re-sign in.)

  4. Very cool project.

    BTW you can avoid the problem with the RGB LEDs not coming on and cycling colors smoothly by giving each LED its own series resistor. So when one LED wants to draw more current it won’t drop the voltage on the other LEDs.

    1. @ Roger Meier – Right. I knew that would allow for the normal color cycle but I really like the way they flicker and randomly change now. Much better for this project. Plus, I didn’t want to risk seeing all of those components from the back. Thanks.

      1. Great project. Would like to make a variation of it but I can’t locate the rbg color changing led’s. Can you help out with a source?

  6. @ Debi – There are a few different sources from Ebay to Digikey.com. I believe I bought mine on Ebay. Let me know if you need more help locating them.
