The temptation to use excessively long wires rather than minimal ones encourages poor construction technique. Which is a disaster on digital boards. Look at the huge loops created by the wires! The radiated noise must be incredibly high. Nevertheless, for an audio frequency project this doesn't matter. If you don't believe me, then open an arbitrary Japanese's consumer electronics device and look at the many many flying wires. Richard said:
There are too few independent GND (return) paths, which tends to put reference and return on the same path, with "unfortuntate" results. Yes, that's terrible on a digital board. A solid ground plane would help an universe here. Nevertheless, for an audio frequency project this doesn't matter. If you don't believe me, then open an arbitrary Japanese's consumer electronics device and look what they do with signal ground. Richard said:
Cutting wires to appropriate lengths is too much effort for most users, and makes re-use unlikely. Yes, but what really counts is the lack of solid ground plane here! Richard said:
Individual sockets, particularly on power and GND rails, tend to become looser and looser. Only, if you insert wires that are too thick. Allowed wires will hardly destroy such a spring contact. I have breadboards, that are 30 years old and work like brand new ones. Richard said:
These solderless breadboards CAN be used, but not as easily and not producing the quality results of wire-wrap or point-to-point soldered circuits. For the audio frequency range I can make a breadboard design where you wouldn't notice the difference to a point-to-point soldered design! It's always a question of how to make it right... Kai |
