Circuit Design Ideas - monitoring RS-232, protecting laser-diodes

rs232 design idea.jpgTwo more inspirations for designing your own circuits - taken from our Design Ideas section.

They involve a hot-swap serial-interface circuit allows two computers to monitor all the traffic on an RS-232 port and a laser-diode-clamp circuit that protects against overvoltages.

Circuits. Circuits. Circuits

circuit search example.jpg
It's still in beta - the Web equivalent of caveat emptor - but check out the emerging new Circuits section on the site. (Click to expand the image on the left)

It brings together the existing Circuit Design Ideas section with an alternative, visually-based view on Circuit designs and diagrams, dubbed Circuit Search - bookmark www.electronicsweekly.com/circuitsearch

We hope to build on the latter, both in terms of the number of circuits presented but also in the means of navigating the circuit diagrams themselves.

And in the not-too-distant future there will also be a Circuits-based competition - stay tuned!
