he wanted to to heat his house, so i think it could be an oven

best threasd ever!!!!!!!!

>>687262
This isn't actually humor... several years ago a guy did a thing where he re-built a older device, and it had blown fluid filled caps. To keep the cosmetics, he hollowed out the old caps and soldered in new caps. I seem to remember him having a viable reason for the different values, too...some other part he had to replace.

>>687262
this is actually a common thing for capacitors and batteries from china. generally people buying two or so capacitors at a time are just replacing the ones in their car stereos that have blown anyway with sooped up capacitor kits so it wont matter.

>>687457

That's actually a good idea.

>>687524
have you ever heard of something called inductance?

>>687254
My iron smells like tuna and there's smoke comming out of the handle for no real reason. But it works so fuck it.

>>687533
>have you ever heard of something called inductance?
Yes. What's your point?

>>687533
Two wires carrying current to item plugged in.
Current flows opposite directions in wires wound same direction.
Inductance wire one cancels inductance wire two.
No inductance observed.

>>687566
>Inductance wire one cancels inductance wire two.

And there in lies the problem. Inductors fighting one another generate heat. Lots of them in a roll generating heat together. Rarely an issue unless you are pushing the cord to the limit with a 2.4kw heater or similar. Throw in some resistance and a rug for some added excitement.

>>687702
the small wires going from the thicker ones, i have no idea im not into electrics

>>687703

The copper plates seem to be huge ass fuses, yet the electricity that flows though them seems to be coming from tiny wires.

>>687702
>>687706
Also: they're color coded, but someone fucked up and swapped white and brown.

>>687702
Rails like that are normally used for insane amount of amperes. One system i worked on had rails lake that carrying 3600A.

Connecting them to those thin wires (which i assume can handle the load) is the electric equivalent of using a tactical nuke to swat a fly.

>>687702
looking at it a little closer, i understand what's so "funny" about it, the rubber plate would be covering the grid supply connections
the wires connected to it are switched, and are a way that they are stealing power

Polymer caps perform better then electrolyte caps and therefore have to be selected at a lower value to keep the ratings in line with the electrolyte caps

>>688279
are you sure you don't mean "same value but smaller physical size because they are more efficient"? regardless of what it's made out of if it's rated to a set capacitance then it should be equal to another type of capacitor that is the same rating

R...Really?

>>688926
It can't be real. Those adapters don't have any intelligence in them to do protocol and logic level conversion, they're just wires going from one connector to the other. A DB25 parallel port doesn't even have a power line, so there's no way the USB device could be getting power.

>>688937
Every one of the data lines on an LPT port is a 5v power line. This was used by stuff like the NESKey.

Nibble mode only uses four pins, so you've got another four free to power the device with.

he didn't imagine he could just remove the central post. it was probably grandfathered in for the old fence when someone replaced the gate with a solid fence. it's about the right spacing from the wall to allow a gate.

I'm fairly certain they go though the wall and somewhere else. Nothing wrong with the smal wires as long as there isn't much power drawn from them.

>>687686
can someone explain?

>>688995
there's a breaker in line. so i think they worked that one out.

but yes, the brown and white wires are switched.

yeh i smirked when i saw it connected the wrong way, but my grin got slowly bigger as i watched it bulge and i burst out laughing when it popped because it reminded me of a dude in college who hooked up a fairly large cap backwards and got completely covered in some sort of yellow powder when it exploded.

>>687702
This is what you will find in a vault, It looks like black, red, white and green.. or a 120/240 feed. This is known as a bussway. The smaller wires are what is known as taps and can only be like 15' depending on what the rules of its time are. This thing is ancient as fuck and we dont do it like this anymore.

>>688885

God damn son, god damn.

>>687702
Its funny for people who don't understand electricity. Those huge rails are meant to carry a few million amps, and those wires tapped onto them can only handle a few hundred. That doesn't mean they'll blow up though, whatever they're powering only draws a couple amps through them.

>>693465
they dont carry millions of amps.. maybe 1000-2000a. the taps are probably #4 so about 60-80 amps and on the back side of the relay on the den rail look like #12 which are good for 20a. Come to think of it I bet the white is just a third phase and this probably isnt in america. God damn yoorop I hope you guys arent still installing shit like this.

On any standard system without tweaking it wouldnt work, no chance. You could theoretically add the tweaks to bios and the necessary information into windows XP to allow it, if you were insane and had way too much time on your hands. Why you would want to go through that much trouble just to read USB through LPT is beyond me, maybe bragging rights.

But yea, somebody with enough coding knowledge could in theory do it. Couple fuckers I worked with at IBM back in the 90's would do it, just because they were bored. But thats like their entire weekend.

Add in the tweaks to bios and xp to recognize and read USB to PS2 (its a mouse adapter btw), ps2 to Com, Com to AT (aka game or joystic port, we jsut called em AT), AT to LPT or Parallel port.

I think I have a few of these laying around here somewhere.

In high rise buildings we have bussing that goes all the way up to the top floor but is protected and has slots so you can just toss a disconnect on it and build the floor to the tenants specs. Old elevator rooms used to have a lot of open wiring.

>no one notices the fuckhuge ladder out the door

>>693642
>not realizing that if you set the ladder up below you will have to put it at such an angle you will be trying to climb through the ceiling of the floor below.

>>693511
Do you think people would really do that? Just go on the internet and lie?

Yes. You. Fuck you and your bullshit. There is no way for parallel port to emulate a USB port.

>>693733
You can emulate just about anything (minus the speed) if you have access to both hardware and software part of it.

>>686733
What color is the 1.5 ohm resistor in the variety pack I bought

>>693490
The picture's a gag.

That absolutely does not mean that someone could not, for shits and giggles, emulate it.

The hardware mentioned could be connected together, and would create a functioning USB tree that's connected to a printer port.

The key component is the serial USB controller, which is essentially a tiny computer, with its own OS, that acts as a USB host, handles the minutiae itself, and sends the important stuff back over a serial link.

Speaking serial over a parallel port is, by comparison, a piece of piss, and if there's not already a product that does it, I could build one and write the driver.

All that's left is writing a driver that ties the usb dongle to Windows' USB host controller class driver, and providing enough power off the printer port to power the whole lot. Which shouldn't be difficult, seeing as it's a module intended for embedded systems, and a USB stick.

It's easy enough to power 5v devices off a printer port: you just tie their power to some data lines, and assert them all 1. Use some diodes if you don't want the port to explode when some dumbass sets one to 1 and one to 0.

>>693918
No you can't, because you can't fucking start talking to it if you're not fast enough. It will try to negotiate and time out because the parallel port can't fucking keep up. You're fucking lying about some tech bullshit and hope no one is calling you on it because you are insane.

There is no serial to usb controller there. The usb2 -> ps2 convertor is only for keyboards/mice that have the ps2 hardware built into the controller on the device, if it detects PS2 vs USB, it changes itself accordingly. The dongle is just some dumb wires.

Parallel port can not be serial port because its clock is too slow, you are retarded. Like 15khz clock for parallel vs 115khz for serial vs 15mhz for USB. Wtf are you thinking mate.

You cannot convert parallel to usb or serial without additional hardware. If you had one very specific application you could make a whole asic that is a usb host, take the data, buffer it, and send it through on parallel at reduced rate, but that is not the same thing as 'hacking the bios' because that is fucking impossible.

Huge internet fight!

>>693965

Sounds like a challenge to the techs. You dont hack bios, you reprogram it. Its all just code.

>>693965
Oh for god's sake read the fucking thread.

The USB-to-serial dongle is a whole entire computer, and implements an entire, self-contained USB host. Think of it like a web proxy, but for USB. It does the keeping-up for you.

You absolutely can bash serial into parallel. What's 8x15, and what's a shift register?

>>693965
Oh, and lookee here. Turns out there's a product you can buy right off the shelf that performs this "completely impossible" parallel/serial conversion at 115.2k

>>693446
That's actually not that bad - It looks worse than it is, due to half of the stepladder hanging in the air. But it is actually quite stable, as long as the guy climbing it doesn't nudge the base off the ledge.

I've climbed setups like this several times:
7/10 would climb again (deducted 3 points because of ladder-climbing not being very entertaining)

>>694300
Except its not. Have you ever used one of those? Its just an adapter. The circuitry is on the keyboard/mouse

>>694359
Keep up, read the thread.

The picture of the dongles bunged together is from ~2004, and has nothing to do with the picture of device manager below it, aside from maybe providing the idea.

>>694304
>$113
Somehow I don't think that is a straight through pin change. I think that just might be a piece of hardware with logic, a clock, and maybe even its own processor. That is not a hacked bios turning you parallel port into a serial port. It is an advanced separate piece of hardware, which I never said didn't exist.

To be fair, its a thermal fuse and not an electrical fuse. Also solder melts at around 300 degrees anyway.

>>692698
You didn't need the heatsink with the p2-300 and below (they went down to 233 for OEM parts). At least for short periods of time or with adequate airflow around it.

Not saying it was good for it, but it would run without a problem if it was one of the slower ones.
