Using Geophone Sensors to detect seismic events
JTAdams @ jtadams.ca has build an interface for his geophones using Raspberry Pi and managed to record some seismic events on this. He writes: I have always been fascinated with how seismic detection can see what is under the ground. So much so, that I decided to try it for myself....

Control accurate incremental voltage steps with a rotary encoder
by Anthony Smith @ edn.com: Experimenting with an HF oscillator, I needed to control the varactor diode voltage in precise increments over a 2V-10V range. A buffered potentiometer was the obvious choice, and connecting two pots in series to give coarse/fine control (or using a...
