0framistanBest Answer 8 years ago If the circuit is not complex, and if you only want to buildone or 2... then you could use a method that i use a lot. Justget a piece of blank circuit board. lightly sand the surface toremove any slight dirt or oxidation from the copper. Then justuse the copper surface as a ground connection for various components. Also, i use a dremmel tool to grind out a fewspots on the board for interconnecting wires. This methodonly works if using larger components, not surface mount parts. I find this method is a good way to build prototypeswithout having to etch circuit boards.
