Hi, I made a microphone circuit using the schematic:Electronics Projects For Dummies Parabolic Microphone and was successful and fun on a breadboard. I then wanted to make this smaller - i.e. on a PCB but i had no luck. I had my college etch a board for me which i checked was ok, but he circuit didnt work, and then I recreated the design on a matrixboard joined with copper tracks.
What could be the issue? I tooked the components apart and recreated them on a breadboard and it works fine again
Also, regarding the copper track i use (it is copper tape) - how do I join the tracks? the adhesive is acrlyic and non conudcive and i have to join them by painting some leitsilber l100 over it and its very annoying
thanks!
