im sort of a beginner in electronics...i thought that if i construct my circuits with PCBs it might be easier than using dot-boards...i was earlier thinkin of using a Dalo Pen with Ferric Cholride to etch the copper and make the tracks..is tht ok??or should i use something else, or should i jus stick to the dot-boards for the moment???Also could somebody tell me a good PCB designing software??preferably a free one...otherwise tell me good ones..might b able to get them...
