NE555 timer sparks low-cost voltage-to-frequency converter
by Gyula Dioszegi @ edn.com: In 1971, Signetics—later Philips—introduced the NE555 timer, and manufacturers are still producing more than 1 billion of them a year. By adding a few components to the NE555, you can build a simple voltage-to-frequency converter for less than 50...

JFET Moving Coil (MC) Pre-Preamp Kit
by Mark Houston @ diyaudioprojects.com: I received the Boozhound Labs JFET Moving Coil (MC) Pre-Preamp Kit a while back and I promptly assembled the small circuit board. I'm a sucker for a simple kit and a hot iron. That is where it all stopped. The circuit board remained complete...
