Did you know you can make PC boards with photo paper and a laser printer? Well, I mean you will still need etchant and the copper clad. You can make the etchant work better with a fish tank heater. You don't want to use something that gets really hot, though. You can also you an air pump from a fishtank to accelerate it.
