Gadget Freak Case #108: The Tube to the Recycling Center Has an Air Ride

Design News Staff -- Design News, September 23, 2007

Let's say you have a Beer Chucking Refrigerator within range and a Can Crusher out in the shed. Now all you need is a way to get the empties out to the can crusher without having to get up and walk out to the shed. Here it is — you just pop the empty can into this vacuum transporter and thwap! Before you can say “one to beam up,” that can is recycled. A 1hp centrifugal blower supplies the vacuum and high velocity flow to send the can through 50 ft of 3½ inch tubing from Ed's patio to the crusher in his garage in under one second. A PIC microcontroller operates the whole system from the time he opens the hatch to the time the little chunk of compressed aluminum is ejected from the machine.

Light Matters: The Unsung Heroes of Modern Health Care
First, let's define "no-compromise." In an ideal configuration, this lamp would use a high-brightness LED (HBLED) that is built into a small, integrated package and is able to produce a large quantity of focused light, operate with a high level of reliability and generate no audible noise. Is this difficult? Yes, but it is possible.
