What guage wires are you guys using for internal wiring on your projects? Specifically I’m about to put my Programmer together and I noticed that most people’s pics have a larger gauge wire than I’ve been using (24 gauge).
I recently finished an Echo Base delay and it’s kinda noisy. I’m paranoid the small wires are part of the problem…
i use 0,25mm² most pf the time, sometimes smaller - ribbon cables (i use the same stuff as ide cables in fact actual old ide cables sometimes)
sometimes i use 0,5mm².
i have noise problems with one bent video device, that uses a quite long ribon cable, but i had no problems with audio stuff.
maybe try shielded wire and put the shield to ground, if the noise id bad?
i don`t think, the noise comes from the strength of the cable, but more the length and where it goes. i think you would want to keep it away from any digital stuff.
Guage of wire wont affect noise. Thicker guage wire is only good if you plan on wiring something up that is over a long distance to help eleviate voltage drop. Personally, i use 22AWG for my projects. If you have issues with noise, either tightly twist pairs together or get shielded.
Edit: Haha, loderbast. Got to the post just before me.
The shielded wires are necessary almost only in devices such as a high gain distorsion unit or the insides of a tube amplifier, especially with low-level signals (guitar again…)
Nothing worth into a shruthi i believe.
The noise comes from length and the proximity of emitting components (often active components, especially the ones with a high-frequency clock (the pt2399 is one of them).
Anyway, the PT2399 chip is not very quiet, especially at high delay times. At the end of a 50k pot it becomes pretty messy.
Thanks for the help. Sounds like I’m safe to use 24 AWG on the programmer. I made my Echo Base with the pots wired instead of directly soldered to the board because I got the wrong pots. The wires are all smashed in there up against the pt2399 etc. They could be shortened drastically, maybe I’ll try that. Although I should try moving the wires away first to see if that makes a difference.
the Echo base is kind of noisy anyway (not saying it’s bad), at least mine. i changed fromm wired to pcb mounted pots, but haven’t tried since then.
in general i use the thickness that the solder pads allow, for pots. the ribbon cables are thinner .14 i believe but not sure.
