The OpenEEG project is about making plans and software for do-it-yourself EEG devices available for free (as in GPL). It is aimed toward amateurs who would like to experiment with EEG.

OpenEEG hardware - Amplifiers

I found the amplifier designs extremely good as a learning material.

Mental Automation, developers of SuperCAD, SuperPCB, mentalSPICE, mentalMAX, and other related products. Tools to quickly and easily design, simulate and analyze electronic circuits.

mentalSPICE Analog Simulator and EDA

"mentalSPICE is a simple yet powerful analog simulator that enables analysis of circuits using a personal computer. The Mental Automation Spice package works directly with SuperCAD, using the Oscilloscope display window for output. For static measurements, virtual voltmeters and ammeters are also provided."

Program Features

• Complete Berkeley Spice compatible inputs and outputs
• Full AC, DC, and transient analyses
• Noise, Fourier, Transfer function, and Pole-Zero analyses
• Built-in models for all common discrete analog devices
• Support for external libraries
• Temperature effects modeling

eCircuit Center - Spice Schematics

"The goal is a site where the learning of electronics is hands-on and fun. And the SPICE circuit simulator is a great software tool to achieve that goal. It hit me the first time I used SPICE - simulating is fun! And because it's easy to use, I've spent a lot of time building and exploring circuits." - Rick
