Software for drawing circuit diagrams

I'm looking for a piece of software to draw some simple circuit diagrams. I've seen quite a few circuit diagrams on the internet that look like this: **broken link removed** does anyone know what program is drawing them?

Does anyone know of a good *freeware* program for drawing circuit diagrams? I dont need to do anything with PCBs and don't need to simulate the circuit.

Thanks

That looks like an Eagle CAD schematic.

If all you are going to do is draw schematics, I would recommend ExpressPCB: ExpressPCB - Free PCB layout software - Low cost circuit boards - Top quality PCB manufacturing
Free, easy to use, good component library, and easy to make new components.

That is an Eagle schematic drawing. Eagle is a good program to draw simple and more complex schematics. you can find it at **broken link removed**. replace the @ with a period to get the URL.
