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.

Bug Labs – Modular Stackable Embedded Computer
BUGbase is a fully programmable computer, with a CPU, RAM, rechargeable lithium-ion battery, USB, Ethernet, micro-SD and serial interfaces, and a small LCD with button controls.
BUGbee is a low-power radio module based on the 802.15.4 protocol, perfect for creating a personal area network (PAN) for machine-to-machine (M2M), home automation and intelligent grid applications.
BUGvonHippel is a breakout module to which you can connect sensors, wires, and USB devices. This module is named after Dr. Eric von Hippel of MIT who wrote the book Democratizing Innovation.
Here are many Audio Effects and Music DIY electronics Articles with Schematics and idea behind the concept. Electronic Music Enthusiasts will find these useful for learning.
Runoffgroove – DIY Articles and Schematics
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.
Splitter-Blend – Dual parallel buffered effect loops with blend control. Schematic and perfboard/PCB layouts.
Professor Tweed – The Fender Princeton adapted for use as a distortion stompbox. Schematic, PCB/perfboard layouts, and photos.
“Fritzing is an EDA – Electronic Design Automation software with a low entry barrier, suited for the needs of designers and artists. It uses the metaphor of the breadboard..”
Fritzing is Product Design or EDA in Simplicity
“in the spirit of Processing and Arduino, developing a tool that allows users to document their Arduino and other electronic-based prototypes, and to create a PCB layout for manufacturing.”
