Soundcard Oscilloscope by Christian Zeitnitz

The Soundcard Oscilloscope receives its data from the Soundcard with 44.1kHz and 16 Bit resolution. The data source can be selected in
the Windows mixer (Microphone, Line-In or Wave). The frequency range depends on the sound card, but 20-20000Hz should be possible with
all modern cards.

The oscilloscope contains in addition a signal generator for 2 channels for Sine, Square, Triangular and Sawtooth wave forms in the
frequency range from 0 to 20kHz. These signals are available at the speaker output of the sound card. These can be fed back to the
oscillocope in order to generate Lissajous figures in the x-y mode.

Some Entertaining Projects are –

Mr. EQ – A simple, yet potent DIY equalizer. Schematic, PCB/perfboard layouts, and photos.

Little Gem – Two 9v battery-powered amps based on the LM386. Schematic and PCB/perfboard layouts.

Eighteen – The Marshall 18W adapted for use as a distortion stompbox. Schematic, PCB/perfboard layouts, and photos.

Tonemender – An ultra-flexible tonestack with clean boost. Schematic, photo, and PCB/perfboard layouts.

Thor – The legendary Marshall 100W Super Lead adapted for use as a distortion stompbox. Schematic and PCB layout.

The Thunderchief project, released in March 2004, was the first runoffgroove.com circuit that was developed using the tubes-to-FETs process. Enlightened and inspired by Doug Hammond’s excellent Meteor circuit, we used the same approach in an effort to capture some of the legendary magic of the Marshall Super Lead. The circuit’s performance pleased us, but there were issues.
