So, a while back I learned that Kitten Belly Fur is the softest thing in the world. Coincidentally, I once worked on an experiment that required me to save cat fur (but not of the belly variety). The experiment was based on a theory that one could collect a bag of fur that was bigger […]

The idea began to percolate in my brain, after playing with the solenoids that were used in the Xylophone experiment.  Watching the solenoids strike the Xylophone is really fun, and the fact that you get to hear music, while being visually entertained, is inspiring!  I was vexed by creating something new for a future event.  […]

If […]

We modified “Das Blinkenboard” (a previous project of Unfocused brain & friends) by adding a few components, and then we were able to play with magnetic fields. But the more exciting thing is that WE’RE PUBLISHED […]

This is a multi-step process and we actually made it through the first stage successfully. It all started […]

I was recently compelled to add blinking LEDs to stone. I had a limestone rock that I carved and it really needed some eyes. I liked how light shines through marbles and wanted a similar effect. But once they marbles are set into stone, the marbles become less shiny. So how can I light them? […]

I needed a cool flashing LED effect (don’t we all?). J made a generic LED sequencing board and I made it groovy. By using a few materials (hot glue, a jar, a bowl, cardboard, more hot glue…) that I had laying about, I was able to create a groovy glue based ambient lighting jar. To […]
