Open Hardware (OH) is people sharing their designs with each other through the disclosure of their schematics and software systems used on their designs.
With Openhardware people meet, discuss what they are doing and ask each other for assistance in finding parts, or looking for ideas to solve a design problem. This is not just about hardware, but software of the hardware as well (GNU drivers). OH is also an opportunity to showcase designs, so others may learn from what the another persons have done.
