[sdiy] ground & power on pad-per-hole solder breadboard

[Happy Harry]

To star or not to star....

The star is an excellent way to assure minimum interaction
through the supplies. But its hard to do from a layout standpoint.

If you separate the real high quality circuits (preamps etc) on
a separate beanch from the dirty ones (like LED drivers, power amps)
you get close to the ideal.
