Build a 15,000 rpm Tesla Turbine using hard drive platters. Here's a project that uses some of those dead hard drives you've got lying around.
In the Tesla Turbine, air, steam, oil, or any other fluid is injected at the edge of a series of smooth parallel disks. The fluid spirals inwards and is exhausted through ventilation ports near the center of the disks. A regular blade turbine operates by transferring kinetic energy from the moving fluid to the turbine fan blades.
Arduino. Aeroquad - An Arduino based four rotor R/C helicopter or quadrocopter. Check out our main website and forum at For feature requests or bug reports, please submit them to: If you are interested in obtaining the latest and greatest code, please visit our main repository at: The AeroQuad is an open-source hardware and software project dedicated to the construction of remote controlled four-rotor helicopters, also known as quadcopters or quadrocopters.
AeroQuad hardware typically consists of an Arduino microcontroller (Mega-2560 or Uno) as the flight controller board, and an AeroQuad shield with various sensors, such as an accelerometer and gyroscope. Arduino. 11 Arduino projects that require major hacking skills—or a bit of insanity. Raspberry Pi has received the lion's share of attention devoted to cheap, single-board computers in the past year.
But long before the Pi was a gleam in its creators' eyes, there was the Arduino. Unveiled in 2005, Arduino boards don't have the CPU horsepower of a Raspberry Pi. They don't run a full PC operating system either. Rasberry Pi. Raspberry Pi and Arduino. Rasberry Pi Wiki. DIY. DIY Network - Home Improvement How-To & Remodeling Projects.

Herbal tinctures are not always made using ethanol as the solvent, though this is most commonly the case. Other solvents include vinegar, glycerol, ether and propylene glycol, not all of which can be used for internal consumption. Ethanol has the advantage of being an excellent solvent for both acidic and basic (alkaline) constituents. Glycerine can also be used, but when used in tincturing fashion is generally a poorer solvent. Vinegar, being acidic, is a better solvent for obtaining alkaloids but a poorer solvent for acidic components.
