Don’t want to pack away all those fun colorful Christmas lights? Check out this informative writeup on how to use holiday lights with battery power.

The orange box is an old Cirque PS/2 touchpad, removed […]
If you really want to understand electric circuit theory, eventually you will need to come to terms with Ohm’s Law. So how can you get the concept across that I=VR? Will your students be able to figure out that V=I/R or that R=V/I, or that all three of these equations are pretty much the same? […]
I give you my pick for geekiest costume I’ve seen this year: a giant LED costume. Yes, I agree with you that it should have real LEDs on the inside:)
Hot glue guns & LEDs – two great tastes tools that go great together – What would I do without LEDs and hot glue? They are integral components to nine tenths of my projects. Well, while I was working on my first instructable I noticed that the LEDs I’d hot glued onto the wires kind […]
From the MAKE Flickr photo pool Funnypolynomial shares his creative take on the LEDkit solderless clock project, using a clear cube enclosure for a multifaceted display – very cool idea! (Hmmm, wonder how this might work out on a sphere …) – Cube Corner Clock – 7:36 on Flickr LED Clock Kit -Red
