huge ass speaker.jpg
57 KB,
I want to play a really loud and high note on a speaker to annoy the idiots at a club 50 meters away from my house, i live on a second floor, have a fully functional balcony and can point a speaker directly at them if it's needed, so how should I do it?

What speaker should i use?
What tone should i play to make it as annoying as possible?
Is doing this legal?

I live in argentina, and 10 years ago my neighborhood was a residence place, but now it's filled with fucking night clubs.
What they do is perfectly legal, they play music loud all the night,...

But to answer your questions as they are, just get a megaphone, and constantly babble annoying things into it while pointing to the place you want to annoy, alternatively record an mp3 and then play it constantly

I am tired of streaming the superbowl.

What I have right now is a coathanger antenna , VHF/UHF converter, coaxial cable, a vcr, a RCA video out and a projector. in an attempt to get local channels.

The VCR won't work as a converter because it's old as hell.
I believe that i need a converter rather than an old VCR to take the signal coming in from the antenna and bring me footballs.

My question is, would an old cable box work? like something from charter or cox or time warner? something like that? or does that only take in X provider's...

old boxes are made for analog broadcast signals. The entire US switched to digital several years ago. You're either going to need a newer converter box or a newer TV with a digital converter already in it.

That said I made a similar antenna and the reception is great. It works better than the shitty $15 box/antenna combo my roommate got from walmart.
>>
google the manual for your TV to see if it's capable of receiving digital signals, aka ATSC. if so, use the settings to set it for digital, connect a wire to the RF input (or your coat-hanger monstrosity) and you're good to go.

if not, you need a $30 gadget, an ATSC receiver, like the super cheap DTA1080D. (dont get that one, it's just an example.)

OP here. My main question is can i use an old cable box from 2012 that was given by a cable company as the converter?

Dentists are expensive as fuck if you don't have dental insurance. No, not medical, explicitly and specifically dental. Which is not commonly given at jobs unless it's a salaried position. Getting that tooth pulled could literally cost him upwards of $1500 depending on how much bullshit they make him do before hand.

Welding Helmets

Anyone have input on the Miller Digital Elite VS the Lincoln Viking 3350 series?

Any input would be appreciated.

I don't understand why the Lincoln is "rated" for overhead welding and the Miller is not. Can the miller not handle getting hot metal sparks or globs bouncing off it or something?

The only other thing is the miller takes non standard lenses but it has that sweet arc magnetism sensor that eliminates getting flashed outside as extra protection along with the...

Check all the options until you find it or read the manual or google, and set it up as pppoe with the credentials you have.

Hello /diy/

So I recently made the acquisition of pic related, which is an adapter for a 9.7" LCD panel.

It needs 5V 1.37A so I'm currently using a 2A USB phone charger to power it since I read 3.0 USB deliver up to 0.9A and 2.0 USB 0.5A

So here's my question, since you can mount in parallel batteries to "raise" their amps, could I do the same with USB ports? (two 3.0 ports or three 2.0 ports)
21 replies and 3 images submitted. Click here to view.
>>
You'll need to put small resistors in series with the device and USB ports to balance them (a couple ohms). If you put two voltage sources in parallel without that one will supply a slightly higher voltage and all the current will be drawn from that one. This will make your PC shut down the higher USB port for drawing too much current, then the second one for drawing too much current. Batteries have their own internal resistance.
>>
>>937937

Pardon my shitty schematic and my stupid question, but I assume you mean putting a resistor where the green arrow is?

Or one for each port where the blue arrows are?

And I'm quite new with resistors, what would a good value for it?
>>
>>937932
>(a couple ohms)
dont listen to this idiot.

a 'couple' of ohms at 1 amp will drop a couple of volts.
meaning burned resistors and low voltage for your board.

usb is current regulated, should be fine.
external hardrives divide their load over multiple usb drives all the time.

Can anyone explain why pic related is frying my 555 timer? I'm using the CMOS TLC555CP. It works fine at 6 volts but 9 fries it immediately. The highlighted 10 ohm resistor is actually a DC motor. The diode in parallel with it should be protecting the rest of the circuit from the voltage spike caused by the inductor. It's a 4148 diode rated at well over the frequency at which the circus operating. Any ideas?

So, I'm having trouble with my sound system in my truck. What it is doing:
My subwoofer is trying to produce sound, every now and then it will hit, but immediately stop. From what I can tell, it might be my RCA cable, the guy who hooked up my system popped open my fuse box under the dash and wrapped it around a fuse before plugging it back in. It worked great until about a month ago. Fuse is not blown, and when I swapped fuses (moved the cable from one fuse to the other) it continues to do the same thing. Anyone have any advice so I don't have to re-run any cable?

Check all wire connections. Most importantly your ground make sure its large enough gauge wire. Is the setting on your amp allowing the correct amps received from your headunit through the rca cords. is it wired properly to matching ohms value.

Are there any acoustics experts on here?

I am trying to soundproof a room in order to contain my roommates snoring. This is a low bass sound, so it is tricky.

I have planned a three phase project to reduce costs. (See diagram) The problem is soundproofing is expensive for a poor-fag like me, and I am trying to essentially make his snoring inaudible, even the low bass rumbling.

I have a couple questions then:

This is a mind over matter thing.
Stop letting it get to you.
It's not the snoring that's keeping you awake, it's you noticing the snoring, getting aggravated at the snoring which activates your sympathetic systems which keeps you awake. It's literally the same thing as like if someone gets chewed out at work/is expecting something bad to happen the next day, and can't fall asleep because of it.

If you really feel you need to do something, buy a loud ass fan to inject some white noise.
>>
Get some earplugs poorfag.

Acoustic foam is nothing but pretty to look at, especially to bass frequencies and foam, bass traps etc are basically room treatment not sound proofing. You'll be wasting your money.

For soundproofing done right it is usually effective to build airtight rooms within rooms. You need to decouple these from anything which can transmit vibrations and add mass to surfaces to reduce vibrations where you can't have a sufficient quantity of air.

The cheapest solution would be to build a sealed box around your bed and ventilate...

139 KB,
OK so I need a breaker that will trip at 65A but its going to be at 84V. Anyone know of something that will work? How does different voltages affect breakers. Like can I use a 120v 65A breaker? Will it still trip at 65A?
9 replies and 2 images submitted. Click here to view.
>>
Since most cheap breakers use a bi-metalic heating element, the trip is at the set current level regardless of the voltage. You can draw it out and do the math yourself, but the resistive metal strip that actually expands generates the same heat due simply to the current passing through it. Voltage in this case is only a reference to the insulation class.
>>
>>940654
>Like can I use a 120v 65A breaker? Will it still trip at 65A?

Yes, if it doesn't have any electronic 'smarts' in it (like GFCI, Arc Fault, etc.) Smart breakers might still work at 85 Volts (how else would they operate when voltage dips during fault). But some operations (like closing) may not work properly.
>>
Mind me asking, what are you planning to do at 84V?
