I'll read you 'duino stuff at the weekend.

yeah I think I already established it was a long way around.... I like to give advice that can be applied to many cases and allows people to think for themselves (sometimes people become very frustrated at me for that). there are also capacitor leads punching through the ground plane and linking top and bottom? all over the place.

but you are still going with the old fashioned 'conventional' view of circuit theory. the electrons actually flow from Negative to Positive, its holes that 'flow' from positive to negative. the signal does not really travel along the wires and then back along under the wires in opposite directions in a nice linear manner. ideally we would like them to flow cleanly, but I would be very surprised if it were that neat in this board. electrons actually flow rather slowly, as opposed to the charge. but thats beyond the scope here, the circuits still worked amazingly, even though we had it all completely backwards.

a 'hole' is the absence of an electron

Hole Flow
Electrons and 'holes'
Conventional Flow vs Electron Flow

now i'll leave you scratching your head, as I was when I first came upon this concept a few years ago

at this stage in conversation its usually easier to just pretend its not happening and not rock the boat so as to avoid arguing/explaining it every time, but its an interesting factoid to bring up here

basically I would make it more than a wire of similar gauge to the resistor lead

Qusp,

I'll give you some advice:

1- Style of comment is IMPORTANT. You could actually destroy someone's livelihood without knowing.
2- Brevity of comment is IMPORTANT. Doubling or tripling the size of a thread is a disservice to EVERYONE.

yeah, had enough of your advice, I dont care for it. the advice you are giving in the thread now seems to be starting to resemble my old livelihood crippling advice anyway. but no, no value in the content I included, even if it predates the research you had to go off and do, in order to come back and confirm what ive been saying all along. it would not have taken up so much room if you didnt argue the point about it so long before accepting it.

you are at least as much to blame for the proliferation of comments

just in case this was taken to refer to the circuit here, it refers to the fact that humanity, all of electronics pretty much believed current to be flowing the other way, but luckily for us, it worked anyway.

qusp, why not just provide suggestions without being demeaning and condescending? I agree with glt.

gusp,

I am confused by your reference to three articles on "holes". Those are all on the atomic level or slightly higher. The unfortunate tangent that the thread went off on was about the path of electrons on a macro level. So I do not see the relevance.

Now can we please get back to building and playing around with the $99 DAC? I know it is has some problems, I bought it to play around with and maybe build a DAC for one of my friends on the cheap.

as is the construction and operation of solid state devices/circuits, you dont see the connection? N channels are doped with electrons, while P channel devices are doped with holes. its the very basis around which these devices work. also subatomic would be more accurate

please override your brain reflex, its qusp not a g in sight

let us know how cheap it turns out

The doping isn't done with electrons (they'd flow away anyway to equalize the charge), its done with atoms which are electron donors. Conversely, for P type with hole donors.
