Title: Elektor Magazine July/August 2007

Description:

Summer Circuits 2007

Elektor& 8217;s annual bumper compilation of circuits,

design ideas and tips

This year we again publish & 8216;Summer Circuits& 8217;, our

extra-thick July & August double issue and the

established number-1 source of inspiration for all

electronics enthusiasts.

For this year& 8217;s edition, Elektor& 8217;s editors and lab

staff have compiled a massive collection of circuits

and deas covering a common theme: robotics. The 2007

Summer Circuits issue we expect to become a must have

item for all robot fans. However, those of you not

steeped in robotics will find lots of goodies in the

Summer Circuits issue too, as all circuits are also

useable in other electronic designs. The circuits and

ideas presented have a wide range and can be lassified

as belonging to microcontrollers, power supplies,

sensors, actuators, communications, chargers,

mechanical assembly and lots more.
