Simple 9v, Ground question

[opg]

I just got in the parts for the Weird Sound Generator, but I'm having trouble figuring out the best way to connect the +9v and Ground points together when using a perfboard. I'm planning on connecting most of the components to each other with their own leads, but I'm having trouble imagining the most secure way to daisy-chain the +9v and ground wires.

I'm using the same design that ladislaobiro used, except that it will be housed in a case with the pots perpendular to the the board and mounted onto the case.

Looking at the PCB version, it makes perfect sense, but something tells me if I just run wires together, stripping them where they meet, that it won't work.

Any advice? And what about having to connect multiple wires to one lead after you've soldered the component in already? I usually overthink these things...

You can certainly overthink these things. It is virtually impossible to figure out in advance the best thing to do. You can't model the resistance in the wire and solder joints.

I would wire it up using the shortest wires with the cleanest layout. Connect all the +9V and Gnd points on the cricuit board together (two separate paths of course) and all the gnd points on the panel. Then connect the battery up to some point on the board's 9v line and to gnd on the board. Use only one gnd wire from the panel to the board too.

If you get hum and noise, the move that gnd wire from the panel to the board around to different points on the gnd wire on the board. You'll be amased that at some magic point, the noise will be minimized.

Some would say using a star layout where everything has a separate wire going back to the place where the battery connects is the best, but I've tried this in the past and it is no guarantee that you won't get ground loops and noise and hum.

I see what you're saying. Thanks!
