When dealing with breadboards it is of utmost importance to distance all similar things equally. Trimming component legs is only acceptable if all components are trimmed equally. When laying out passive components it is of utmost importance to insert components such that their respective values all face one direction. Resistor color bands must always be aligned. For functionally similar connections, wires of exactly the same color must always be used. And so on...
If you stray from these simple rules, know this: somewhere, in a small, but highly organized room there is an autist screaming of pain.
So I guess this is a thread for things that just make you feel warm inside. Like super neatly organized cabling etc.

How did you make the supply portion to fit into the breadboard? The outer rails don't align to 2.54 pitch of protoboard...

Much better now. I feel that the dials aligning up in zero position is a good sign.
>tfw this is as good as it gets with jumper wires
Can't wait to design the board and go all in with aligning the tracks and components perfectly.
>>895188
If you aren't cutting your leads when you're doing breadboards to reduce height to a minimum i don't even want to talk to you fam. That board's already ugly af tbqh.
>>895269
I see where you're coming from. But you cut them twice: first for breadboard and after that trimming through hole...
>>895271
With 2-layer designs you rarely see resistors that have more than the minimum spacing anyway so it typically doesn't matter. Idk, it really doesn't matter what you do if it's a personal project and if it's work related then you probably aren't doing something too serious otherwise you'd have that shit rigidly fixed in place at least on a protoboard.
but us autists will argue anything. What are you making anyway?

NE555/CD4017 8-step sequencer with fixed/variable bpm (fixed 128 for them techno vibes and variable for just general dicking around). Hooked up to some additional NE555s configured such that each "note" is variable frequency and duration. Haven't gone into amp/filter yet, but will during weekend.
> >tfw this is as good as it gets with jumper wires
no it isnt. if you used proper 24awg wires instead of those pin-at-the-end monstrosities, then you would be able to see the circuit, and probe around so much better.
>>895344
I was under the impression these solid core wires have some other name instead of jumper wire. Oh well. I've used them before, but I had to resolve to using tweezers to twiddle around with them.
Now I just have one board that has the power rails hooked up using these.
> tweezers to twiddle around with them.
i use a tiny pair of needle-nose to insert wires, and to splay the legs on components, straighten pins, pick up and deposit parts, etc etc.

It's not easier to maintain, wires will get all tangled and shit.

Get a spool of wire-wrapping wire and cut to length. IIRC 24AWG is about right for breadboards. If you're lazy, buy a pack of pre-cut wires.
I wire my breadboard like pic related, but it's not practical for larger circuits. I think I will try >>895490 What wire is that? It looks like wirewrap wire.

That's a perf / vero board though. The bread boards are the ones in which you don't have to solder
>>895691
Perfboard falls under the category of breadboards. What you're talking about specifically is called a solderless breadboard. (Originally breadboards were literally wooden bread cutting boards people built electronics on.)
>>895210
Umm, no. I'm messy. But with the board under test lying on that much conductive crap, odds are it would never work. Worse yet, it would work and I'd never know which short I'd have to replicate in the production units.
>>895218

>obligatory "wire wrap has been to space" comment
>>895762
Your phone almost definitely has some 70 year old wire wrap in it.
>>895773
Sorry, but they're all-digital by now.
>>895923
Digital or not, landline phones need wiring.
>>895926
The only wiring left that might be 70 years old is the line from the phone socket to the nearest exchange, from there on it's all new, and mostly fiber. Where you live may be different.
>>895928
Yeah, it's the same here. And the Telcos are really unhappy with the need to maintain the old copper wiring.
>>895737
Wire wrap is more robust against vibration than printed circuit boards. 7 turns and a square post results in 28 redundant contact points. No cold solder joints. And signal pairs can be twisted in sensitive radio equipment.
>>896076
oxidation will eventually make all those 28 contact points intermittent. not so good after 10-20 years.
>>896098
At work I literally have a wall of 15000 pairs wired up that way and many of them are 20 years old, there's no maintenance schedule for 'uh oh, this is an old wire wrap, better redo it.' The only ones that get soldered are the ones to the paper insulated cable, and that's more of an issue of the style of those old protectors. Even then it's trivial to do because they are already wrapped up nicely.
>>895350
You say that like tweezers are a bad thing. If you have a nice set of tweezers they are very, very handy once you've gotten used to them.
>>896098
The connections are gas-tight, any oxidation happens on the outside.
>>895188
this is what I work on. A whole lot easier than any printed circuit.
>>895761
>>895551
i do this too, for small stuff.
like this smd rgb amp for my pc-engine, pic related
i've gotten the through-hole svideo mod for genesis consoles down to a 5x5 perf board using just component leads. there's something so satisfying about shrinking stuff down as much as possible.
>>895748
>with the olives removed
>>896914
Why would you use s-video when the genesis is native RGB?
Hell, why mod it at all? Just use a SCART lead and an off-the-shelf dongle.
>>897614
Hnnnng
>>897539
i don't, personally. i have all my systems hooked up via RGB to my bvm-d20f1u.
buying a lot of 20 genesis consoles for super cheap and throwing in a quick svideo and a/v out mod can net a decent chunk of profit. i have 10 or 11 left to do. plus, in the states, RGB and scart connections are foreign. the 30 year old guy that wants to play sonic again just wants a system with easy connections.
i might do 50/60hz and overclock mods, maybe install different color power leds in the last ones i have. you know, just to get a few more jew bucks outta ebayers.

what does it control in that circuit?
>i don't really understand the hate for arduino
i was just wondering, not getting haughty or anything
>>898359
>what does it control in that circuit?
It controls the gate pulse of a triac. A simple zero-crossing detector detects when the AC signal crosses zero, the arduino waits a specific number of microseconds (controlled in this experiment by the pot) and then fires the triac through an Opto-triac.
Its like those fan or light regulators which can control the speed or brightness but its controlled by a micro-controller.

>>895387
Disagree. Unless you don't have two hands and snag covers on your cables.
>>895367
it looks neat
but which is easier to alter?
the left.
what is it fucking patch panels and switches?
why do people insist on putting patch panels and switches in different racks or fucking miles away, just mix them in and if you plan it right you just use like 1/2 or 1m patch cables and you don't need trunking or channel.
the only time you should be needing cable management like this is at the back of the patch panels
>>899280
>the routing of those wires
>>895551
don't worry, watch people go apeshit over how i make traces
>>899325
let me know when your next project hits construction phase so i can buy shares in solder.
>>899325
Thats exactly how I make traces. People go nuts over it, but its still the cleanest way to make traces.
>>899305
At that point why not just do a custom PCB for it? You've basically expended the same amount of work in planning but would save yourself hours of time when it comes to assembly
>>899489
I'd argue that, at that point, it's much easier to layout a PCB than perfboard.
>>899280
how do i bend copper wire like this, i do use copper wire which is made out of a single string of copper so it's less bendable like in this picture but i alway mess up and can't get it as beautiful and straight as this.

Just beautiful man, the kind of work someone will look at in 50 years and go "man, this guy was a fucking pro".
Do you lay your link wires before or after components? They look too aligned to have gone in before, but I can't imagine how you'd do it after components because fuck all space to manouver.
>>900161
Cheers. I usually fit the wires last, so they are not disturbed by reheating the solder. Not usually what is taught when trying to protect semiconductors from heat but *shrugs* I try to be quick
>>899457
Unless you're laying wire down, you can't really do this and not end up with bad joints. Wet solder will not bridge the pads, only non-eutectic solder will when it's in the pasty state, which doesn't yield good electrical connections.
You can even see the bad joints in >>899325
on row 13.
So I would definitely not call this a clean method.
>>900155
>>900156

>>900188
You're welcome. Good channel separation, ground routing, eliminating noise etc can be a much more involved task with audio projects. I won't pretend to be an expert but at least you can 'hear' if you're on the right track.

components up on their ends or flat?
