HOW TO – Make a Strobe Out of a Monitor…
Matthew writes “A project I’m finishing off involves a simple little front end that I’ve decided to implement using some DHTML. As I was reading up on JavaScript’s setTimeout method as part of my DHTML research, an interesting thought crossed my mind: would it be possible to make a strobe light out of that old archaic CRT monitor sitting on my closet floor and such a weak (as in weakly typed) language as JavaScript?

DIY satellite of sorts…A Russian Orlan spacesuit with three batteries, a radio transmitter, and internal sensors to measure temperature and battery power – “One of the strangest satellites in the history of the space age is about to go into orbit.

Refik writes “Here’s a free Funcion/Signal generator. Engineers and hobbysts need a function generator to test their circuits if they are working properly and it happens that they don’t have money to buy a function generator or don’t have time at the moment to build one! This function generator is a free of charge software that needs just a sound card in the computer!”

By applying this technology in areas that are badly in need of critical communications infrastructure, more people can be brought online than ever before, in less time, for very little cost. We hope to not only convince you that this is possible, but also show how we have made such networks work, and to give you the information and tools you need to start a network project in your local community.” – [
