LAKE WALES Fla.—Graphene is easily grown with chemical vapor deposition (CVD) on copper foil, but a simple way of etching out the necessary circuit patterns and transferring them to a non-metallic substrate has eluded engineers. Now researchers at the University of Illinois (Urbana-Champaign) claim to have a one-step room temperature process for quickly patterning and

About Burglars Recently the Spiegel published an article about burglars in Germany: Burglars prefer the dark months. In december the insurances report 3 times more housebreakings than in july. The police reports that it is very difficult to find the delinquents. Mostly there are no witnesses and no traces. Only in 2,6% of the housebreakings

Introduction Besides looking damned good on an otherwise bland and ordinary desk, this project is about more than just being attention grabbing eye candy. It’s about demonstrating a small portion of our single board computer capabilities by hooking up a color sensor, RGB light strip, and enclosing it in a nice looking wooden enclosure. We’re

In this post I will document an OCXO upgrade board I designed for the Fluke/Philips PM66xx line of frequency counters. Introduction A few months ago I purchased a Philips PM6674 frequency counter on eBay. It’s an older 9 digit counter with two channels that has a maximum input frequency of 550MHz. The design feels dated

This one is an interesting one, it’s something we’ve been looking at for a while and figuring out how to solve it. We have sets of speakers and projectors and the users keep losing the remotes, or misplaced/stolen. Usually this wouldn’t be a problem, we’ll just contact the supplier or manufacturer and order replacements. Except
