For the second time in the last month, the transformer on my street went haywire and the power went out on our street for a few hours. Fortunately, we had plenty of flashlights and candles (old school FTW) to keep the house well-lit enough; unfortunatley, my phone’s battery is about to die, and there was no available power. DIY weblog Tinkernut shows us how to power your phone with the heat of one of those candles, thanks to thermodynamics, thermoelectric effects, and a Peltier effect device.
If you’re going to Washington D.C. (or will be in the area) before this Labor Day (September 3rd), you can’t miss the LEGO® Architecture exhibition at the National Building Museum, entitled “Towering Ambition”. The exhibit just added three new iconic buildings to the 15 already on display, and they…are…HUGE!!!
