Actually folks, copper filling is only for the looks, it does not connect to anything.Grounding the copper area is really a HF habit - i used to build things like transmitters for the VHF range, and the habit with those is to have grounded copper plane wherever possible.
In an application like this i think it won't matter at all, its all near-DC running around. The only reason for leaving the pieces of copper is to save etchant. It can be convenient to use a ground plane anyway, especially if they run right past a ground connection anyway.
If you take a look at prototyping photos, where it's printed on sheets of normal paper, you will see that I have printed out two variants, with and without copper fill.
It seemed that copper fill was giving really professional looks and feel, and also , as you stated, save etchant. Took 20 minutes to etch the thing, it was a lot of copper to dissolve.
Gotta love protoprocess though, when you take the PCB from the lamp to the photocover removing fluid, that's epic. One second and all the lines become visible.
Damn magic of todays advanced technology :crackup: Just can't get enough of suprises...
