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.
I feel a little uneasy looking at those st ups.
How did you make the supply portion to fit into the breadboard? The outer rails don't align to 2.54 pitch of protoboard...
One of these things JUST
Theme song for transporting it into the bin.
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.
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.
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.
Replacing this mess with a new splice
the messy side is ugly but so much easier to maintain. if you want both neat and ease of maintenance, then channel is the answer.
It's not easier to maintain, wires will get all tangled and shit.
There is a channel, all the blues are going through it.
Cutting a zip tie at a time or velcro isn't harder than fishing a wire out of that shit.
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.
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.)
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.
Your phone almost definitely has some 70 year old wire wrap in it.
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.
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.
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.
this is what I work on. A whole lot easier than any printed circuit.
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?
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.
my highest density veroboard project.. never again
it looks neat
but which is easier to alter?
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
>the routing of those wires
don't worry, watch people go apeshit over how i make traces
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.
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
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.
Good spotting. I found them a simple platform to learn on. The limitations can make larger projects a challenge though, hence the extra ROMs and in this case two Picaxes because.. 'difficulties'. inb4 Learn 2 embedded C yes I know
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.
That guy however, is an expert and shares a wealth of useful knowledge on many audio related subjects. Check it out.
I built one of his 100W guitar amps years ago, excellent wee amplifier.
components up on their ends or flat?
sharing holes in a perfboard, way to be or absolutely unacceptable?
as tight and small as physically possible regardless of all else, or plenty of breathing room?
what are the other guidelines you follow religiously that haven't yet been mentioned?
Single-sided board I etched years ago. I swear there were more air wires than traces on this thing.
I find the limitations fun - it takes me back to my early Commodore Pet days when you would write code that was as tight as possible.
Now playing with esp8266 and waiting for its big brother -due out soon with 40gpio and lots more memory.
This is my AS electronics project.
I'm not autistic.. right?
>and they said It couldn't be done.
Just fucking gorgeous anon. I plan on using the same technique for some toys I'm making, saved for reference.
