Home-made Valveless Pulsejet

In 1906 the first pulsejet was patented and since then has provided entertainment as well as opportunity for innovation and improvement. How a pulsejet works is actually very simple. With a valveless design (which this is), fuel and air are directed into a combustion chamber. Once the fuel has ignited, flame exits the exhaust tube […]

Sun Logger

[youtube http://www.youtube.com/watch?v=SPvRGtFM5UM?wmode=opaque&w=620&h=349] A data logger is a device that is left to run for long periods of time, making regular measurements of external sensors. We’ll be using the Arduino microcontroller and a homemade “shield” (an Arduino accessory board) to create a device that gathers data on light-brightness in an area and how it changes over […]

Capstan for Winding Kite Line

This hand-cranked capstan pulls down kites easily and quickly but is lightweight and portable. A power option can be added for even more ease of use. The line ends up on a removable halo spool, so spools of line with varying weights can be used on the same winder. The winder is built from standard […]
