Looks like less is more when trying to master flight. This small helicopter is using a brain that is based on the brain of an insect! “As tiny as insect brains are, they can still perform extraordinary acrobatics in the air that human flying machines have yet to match. Now scientists reveal a miniature helicopter, with an electronic brain inspired by insects, that could help lead to better takeoffs, flights
This is one of the coolest chairs I have ever seen. It looks very sturdy, with a few modifications I could see this being used as the seating that is stored in the closet waiting for an occasion where you have lots of guests. A cloth band that locks the folds in the selected configuration could keep the chair from re-contorting over time. Video after the jump. Via: India Uncut
These snow and ice speakers are not you everyday outdoor speakers. I am sure the 2007 Michigan Tech Winter Carnival had no shortage of good music with these things belting out the tunes. “As part of a statewide snow sculpture competition, some Michigan Technological University students have added balance to the millennia of snow angel production–through the evils of rock. System includes: Source Member’s computer with optical out, s/pdif Processing
This instructable shows how to build your own RF probe. The parts needed might already be in your parts bin! “Probe for measuring in the Radio Frequency range built inside an earphone jack, designed to have minimum capacitance and complete shielding. What is needed: A diode. Germanium point contact, OA79 or 1N34 is the preferred and traditional choice. But a modern substitute will be a schottky (gold bonded) diode. These
Ever wonder how induction heating worked? Me too… Penguin Labs has an informative article about some of their experiments. “Induction cookers, furnaces, stoves and all that jazz are now widely used. You put your metal saucepan on top of an innocent looking glass plate and it magically heats your food with no flame and almost no waste heat. They are able to heat certain metals up to their melting points,
This is almost as funny as the USB dog! I hope that’s a full flashbag in your pocket. 🙂 “The size of the device changes depending on the amount of data it holds. When the device is about to blow up you will see the familiar error message on your screen: “There is not enough free space”. When switched off the flashbag remains pumped up, so you can estimate with
This RF Remote Controller project is very well documented and even has a step by step explanation of what the PIC microcontroller code is doing line by line! “On these pages, I will introduce Remote Controller with Radio Frequency. The electric wave sending-out is controlled with the code by PIC for transmission and the code is deciphered by PIC for receiving. The 2 stages FET amplifier is used for the
