Portable Cooler Fan : Cooler Table : Used True Coolers Portable Cooler Fan
"Stay Cool - Old needs new technologies" "Stai fresco - vecchi bisogni nuove tecnologie" EBSQ AWARD WINNER Speaking about fans my mind runs immediately to those painting seen inside the Pyramids or Egyptian tombs where you could see the Pharaoh with his slaves making him air with big fans made of leaves. Since than, what’s changed? In two words: nothing and all! The need to stay cool is the same. The technology how we do that… it is all an other world! This watercolor represents a portable fan and its battery, an interesting object to handle in those hot days when neither a leaf moves on the trees. This is a watercolor painted appositely for the EBSQ "cahtch the breeze" show on 5 x7 inches Fabriano 140 lbs Watercolor paper. I used Winsor & Newton watercolor and Indian black ink. Prototype LED lighting rig
This image shows a prototype LED lighting rig I just put together, powered by a 350W computer power supply. There are 18 high brightness white light LEDs in the array and it is not possible to look directly into the array. I estimate the array kicks out around the equivalent of a 200 Watt bulb (it consumes around 20 Watts). Each LED is fed by a 39 Ohm 10W power resistor and there is a CPU fan on the back of the array to provide some forced-air cooling.
