Is there a calculator location for resistors needed for led's. I can't seem to find it on your site.

Hi Dave,

You can find it here:

Sounds like that was on Hacked Gadgets, it was just pictures and not build instructions...

Your cat deserves a big fish! This is exactly what I've been looking for and the price is purrrrrfect! I have a basement home theater but the builders only installed a single pole switch at the TOP of the stairs. My son sleeps (lives?) in a room down there too and more often than not leaves the light on because he doesn't want to go back down the stairs in the dark. What I spend in parts to build this will be paid for the first two months it's in operation.
Well done!

The rotating LED circuit is really cool, I would love to build it for a school project! Is there a schematic available? Thank you, John

Sorry, it isn't available right now.

Is there a way to defuse the light from a led. They have a tight focus... In hopes.. grin..

Hi Dave,

Yes there are many ways. The easiest is to scuff the head of the LED using some fine sand paper.

I enjoyed your Stair lights Project. Good Idea....And I am getting ready to add one to my stairs. So soon I will order the kit. my field is in electronics and in electronics, you always tend to get amazed at things like this.....Good, wonderful, useful project...

Thanks for getting back so quickly. Good info...

Got my order today and everything looks great. The 2 grouping of resistors I received were not marked to determine the differences can you provide some info to determine which is which? "resistors for large LED package " 470/360

Thanks for all of your help,

Hi Dave,

Here is a guide that should help.
