I have been trying to make a radio transmitter out of paper and aluminum and that kind of stuff and each individual peach works but i'm more of a noob to all this stuff and don't have much of the equipment or knowledge to debug whats wrong. Its not as hard as it sounds to make the resistors and stuff for example I can make a resistor with a pencil and a peach of paper by just writing a dark line on the paper and hooking wires up to both ends. And for capacitors I just got thin paper and aluminum foil and rolled it up. For other parts you need to make the usually a quick google search finds it but i'm sure that you know enough about the parts to not have to do that.
