If I wanted a crossover for a sub, which I do, I would use the equation N=(SR[a*u*u0/I])*20pi, right. (Its the one off of that website you sent me to. What are the v...

Re: Creating Custom printed PC Boards

Thanks All of you for your help, but you are suggesting methods that require a laser printer. I don't have a laser printer, though. Is there any way do do this with an inkjet?
Thanks!

Creating Custom printed PC Boards

How do you transfer a PC board design from a magazine to a copper board. I bought a kit from radioshack and it said to use carbon paper then go over the circuit with a pen. That doesn't work, though. Thanks for your help
