CircuitLab - Online Schematic Editor and Simulator

Draw and print beautiful schematics for lab reports. In-browser simulations make it easy to quickly learn electronics concepts. No need to Install, it is a Online Web Application !

CircuitLab - Online Schematic Editor & Simulator

Test and Simulate circuit ideas before breadboarding. SPICE-like models with a mixed-mode simulation engine help you apply one tool to a wide range of design tasks, from digital to analog, DC to VHF and beyond.

BJT Cascoded Active-load Differential Amplifier with CMFB

BJT Cascoded Active-load Differential Amplifier with CMFB

Build non-op-amp Common-Mode Feedback (CMFB) - This kind of high-gain differential input stage might be useful as part of an op-amp, but it's a bit silly to include an op-amp within a stage another op-amp......

Some Examples
  • 555 Timer as Oscillator / PWM Generator
  • 7805 & Wall-wart Experiencing Voltage Drop-out
  • Digital 4-bit counter and DAC
  • Diode full-wave (bridge) rectifier
  • Laplace transform step response and Bode plot
  • LED with resistor biasing
  • MOSFET switching inductive load
  • Op-Amp inverting / non-inverting amplifier
  • RLC resonance
  • Zener diode voltage reference

Open Source Hardware - OSHW Draft Definition

OSHW Draft Definition 0.3 is based on the Open Source Definition for Open Source Software and draft OSHW definition 0.2, further incorporating ideas from the TAPR Open Hardware License.

Open Source Hardware - OSHW Draft Definition

Open Source Hardware (OSHW) is a term for tangible artifacts - machines, devices, or other physical things - whose design has been released to the public in such a way that anyone can make, modify, distribute, and use those things.

Open Source Hardware - OSHW Draft Definition

Open source hardware is hardware whose design is made publicly available so that anyone can study, modify, distribute, make, and sell the design or hardware based on that design. The hardware's source, the design from which it is made, is available in the preferred format for making modifications to it. Ideally, open source hardware uses readily-available components and materials, standard processes, open infrastructure, unrestricted content, and open-source design tools to maximize the ability of individuals to make and use hardware.

Adapteva - Andreas Olofsson at OHS

Making parallel computing easy to use has been described as “a problem as hard as any that computer science has faced”. With such big challenges ahead, we need to make sure that every programmer has access to cheap and open parallel hardware and development tools.

Open source hardware gives people the freedom to control their technology while sharing knowledge and encouraging commerce through the open exchange of designs.

Noise Measurement - To accurately measure noise (or high frequency signals) with your oscilloscope it is necessary to reduce the radiated noise that is coupled to your probe. - EDA and Design Notes
The gEDA project is a set of tools for electrical circuit design, schematic capture, simulation, prototyping, and production. The PCB project contains a tool for printed circuit board layout. - EDA and Design Notes
