It looks like I pulled it off.
I got myself a photo resist coated PCB (copper clad board with a green layer), and a transparency suited for inkjet printers. I printed my PCB circuit, and exposed it the way most people do except that I used a board and glass (from a picture frame), and sandwiched the circuit and the transparency together for 5 minutes under a halogen lightbulb for about 15 minutes.
I did 1 part of developer solution to about 7 parts of water and then everything seemed to work out with the design.
Now maybe I can sign my board too :wink:
By the way, I have done it with my regen receiver circuit, and it seems to work well, and it begins to follow the colpitts equation.
Now its the matter of condensing my circuit.
