That said, a small value resistor (I tend to grab 100 ohm) followed by a capacitor to ground helps decouple the circuits from one another. So, from the 9 volt battery, EACH circuit will be powered by a wire that has passed through a different resistor and has a cap across the power rail to ground.

BetterOffShred wrote:Yeah I'd use 5 rows and have the 9v battery ground go to one row, the 9v + go to one, then run a 100r resistor from the + rail to each of the 3 remaining rows.. then an electrolytic cap positive leg on each of those 3 rows with the negative leg going to ground.
So then you have 3 decoupled rails with a 100r load resistor off one 9v.. any of the remaining holes from the power rows can have the positive wires of your devices, and then the negative wires go to the ground row
Here's a slightly more complex thing that does what you're asking.

If you're going to start tinkering, do yourself a favor and buy a bunch of components from eBay or Tayda or something similar.
There's a million ways to build it man. These were just our ideas, at the end of the day you gotta build it yourself. I use card stock on the conductive side of stripboard usually to prevent shorts. Tape it on or whatever. Hot glue is a fucking mess and pretty final, so mods become a pain in the ass.
