Cheap Robotic Microhelicopter HOW TO
RC model helicopter prices have reached a point where all sorts of challenging (i.e. crash-prone) robotics projects become affordable. This document explains how to build a 300 g, 3D-capable helicopter with embedded Linux and Bluetooth datalink for less than 500 EUR. As a proof of concept, we provide software which allows the helicopter to be remotely controlled over Bluetooth with a PC joystick. Future work will focus on the integration of sensors (IMU, altitude, magnetic compas, GPS, camera) and flight control software (either third-party or dedicated). [via] Link.

Carbonating tap water to make seltzer is easy, fast, and absurdly inexpensive with my improvised apparatus. All that is required is to place CO2 (carbon dioxide) gas in agitated contact with chilled water for a few seconds.

Ultimate Barbeque – HEMI- Powered 345 horsepower, 5.7-Liter V8 Grill. This is the ultimate grill, short of adding in a jet engine. It can cook 240 hotdogs in 3 mins. This was all part of a “What can Hemi” contest. [
At Algoma University the mature students in the fast track accelerated second degree program are not quick to accept theory without proof. As a result, Professor George Townsend offered extra credit to anyone in his forth year Computer Networks course who could take up the challenge of implementing internet based protocols over a new form of medium – Bongo Drums. Eight weeks later, the first public demonstration was given to the class by using a simple ping packet. With a blinding 2bps speed, the class sat patiently as the packet was received in roughly 140 seconds. [
