there must be some free programs i can download or something that i can use for drawing ccts on my computer....anyone have any links or recommendations?
I would like to be able to better utilize these boards as well as improve my homework and note taking!

Thanks!!

 

It looks like you want to simulate as well as draw, in which case LT Spice is free (but limited). Free has it's own costs.

If you just want to draw there is PaintCAD, a bunch of templates I've come up with for M/S Paint.

Linear Technology's LTSpice is good and free.

Texas Instruments' Tina-TI is available for free on their site.

If you don't need/want SPICE simulation capabilities, but just want to be able to draw schematics and make PCB's, check out Cadsoft Eagle.

Google is your friend.
