The following instructions detail how to build a simple pummer using a BC2 (Bicore) BEP (Bicore Experimenter PCB). A pummer is a solar powered self activating LED flasher. The difference between a pummer and a BLFNAR (blinky light for no apparent reason) is that a pummer has a soft turn off, which means that it turns on fast, but slowly fades away.

And with redundant repetition of words which signifies lack of vocabulary and general brain melting. Looks like it while take a while to completely return, because apparently my brain is still vacationing. I think some science reading (of links) will help:

Chladni Plate experiment makes for a jaw-dropping video There has been many ways to visualize the effects of sound, but this one called Chladni plate by the name of its inventor is particularly striking. Flat metal plate vibrating with a sound wave produces amazing patterns in the sand, which render more and more complex with increased frequency. |

Instant Art Career: a Kinetic Painting Machine by Niklas Roy A 'public painting machine' based on CNC device principle allows passersby to paint by pulling the ropes. The paintings are then exhibited and auctioned. Too bad the brush strokes are pretty much limited to horizontals and verticals. |
Now that we've refreshed our brains with some science experiments, hacks and creative pursuits, I can wish you happy Wednesday… And what was the other clever thing I was going to mention?.. Not sure...
