Hello guys,

Can you suggest a 'Low cost electronics project'? anything that has included an instructions on how to build and a PCB layout and included what components are being used in the project. Been searching about this stuffs lately, but I didn't find any projects that include a complete 'how to build' instruction and PCB layout. If you have some small projects there, I hope you can share it with me. Our teacher says to have a useful but cheap electronics project. I'm thinking of a 'alarm gadgets, or projects that compliment with computers, or timer(stopwatch etc), or something that uses light using LEDs' or any small devices that are compose of cheap components and easy to build.
