Some interesting things I found on July 7th, 2008:

# Parasite - Single Voltage-Controlled Resonant Bandpass filter with dual Low-Frequency Oscillators.

The Parasite is a single-channel filter of the exact same topology as the Plague Bearer, with extra goodies to enhance its usefulness.

Parasite features

• The VCRBPF has a Mix control - akin to “Depth” or “Wet/Dry”.
• Two independant LFOs, each with Saw, Ramp, Triangle, Square, and Sine waveforms.
• Each LFO has a rate control as well as a rate indicator LED.
• The filter’s High and Low cutoff frequencies each have a panel control and a switch to select LFO A, LFO B, or neither.
• The High and Low cutoffs also have a modulation depth control to vary the amount of effect from the LFO. (Thanks for reminding me!)
• 1/4″ Switchcraft jacks for Input and Output.
• Power switch.

You can order one for $230 (still 8 left at the moment).

This site is an archive of one of a kind cassette tape recordings and other odd sounds that I have discovered throughout my years searching thrift stores and garage sales. I hope you find them as fascinating as I do. Enjoy!

# Project C-90 | Home - This page is dedicated to cassette tapes. Here you won't find any kind of scientific research, technical data or things like that. The authors' only message is just to give a visitor something interesting to look at.

# Poorman’s oscilloscope (with Arduino + Processing) - This software allows you to get a visual representation of an analog signal using Arduino and Processing. The resolution is 10 bits so this is not like a real oscilloscope but it is still pretty useful.
