Open Circuits is a wiki for sharing open source electronics knowledge, schematics, board layouts, ports and parts libraries. This include open hardware Music Players, atomic microscopes, PC, PDA and mobile phones, and batteries. Please help us to build this resource by submitting your component descriptions, projects, techniques, and PCB footprints.

Open Circuits – Open Source Electronics

Some Projects that look Interesting are

  • Multi-purpose Embedded System
  • dsPIC33 Development Board
  • ADuC832 Development Board
  • N8VEM Home Brew Computing Project

The Open Source Movement, typically covers Open Hardware, Open Firmware, and Open Software. The Open Firmware movement provides firmware which you may also know as soft-IP or FPGA coding see Open Cores for more details.

Excellent examples of Open Hardware projects range from projects at OpenCircuits to Tiny Embedded Ethernet Devices and Advanced & Intelligent Camera Designs which provide solid-state camera and FPGA assisted hardware designs. A solid overview of projects can also be found at Open Innovation Projects.

Optical Retro-Reflective Proximity Switch

This circuit is used to detect objects by reflected infrared light. It can be built into a cylindrical enclosure just like an inductive proximity switch. This is also useful as a level detector for colored liquids like oil. This has some immunity to ambient sunlight as it detects ac pulses. InfraRed Detector for Proximity Switch InfraRed LED Flasher for Optical Switch This is a Hand Crafted PCB Artwork done by a PCB Vendor years back, this method may be used even today. PCB Design – Solder Mask Partial Component Layout This Layout may have many jumpers and may need to [Read More ....]
