how did you find us?
last time we got so many retards was when clover changed the default board to /diy/

first of all, you can just get a hole saw and cut any random sized hole that will fit it. secondly, you need calipers to measure that because you need to measure it from the back, you want the smallest hole it will fit in so the screws are supported properly but we cant see how big the flange is on the back.

Finally, there is more to just building a box. you need to know the characteristics of the speakers. things like the QRS rating of the speaker and the power rating in order to build a box with the correct dimensions/volume or you may as well just leave them on your desk as well as a range of other factors like which frequencies you want to target.

holy shit its held together with electrical tape throw it in the trash.

You want a high static pressure fan. Thick radiators cause an increased pressure drop across them, since the air must travel further in a confined space, with all the extra fluidic losses that incurs. Fans optimized for relatively high pressures are exactly what is called for here.

Mixing high-pressure and high-flow fans will show only minimal effectiveness. Simply put, by increasing the flow across the high-pressure fan, you disproportionately decrease its effectiveness. Trying to do so with a high-flow fan would bump up total airflow only slightly for that reason.

You'd be better off doing a push-pull with two high-pressure fans, in almost all cases. Even thin radiators do comparatively poorly with high-flow fans, because high-flow fans are made to be used with almost no pressure differential across them; that is to say, they're for moving air in and out of a relatively open space, not across any significant restriction such as a radiator or heavy filter.

All that being said, "high static pressure" and "high airflow" are entirely relative terms. Performance in terms of efficiency can only be expressed in terms of CFM/watt, because the obvious route to go in for just straight-up flow rate is an obscenely overpowered fan (looking at you, Delta).


Tl;dr: None of this fucking matters unless you're willing to actually do airspeed measurements, temperature and flow rate measurements of the coolant, consider power consumption and noise levels, and do some basic math to determine efficacy of the system as a whole. Watercooling a PC is a game of diminishing returns in the first place. Just get two fans with relatively high pressure ratings and be at peace with the world.

I use a sunon 12W fan. maximum rated power most motherboards and fan controllers can support is 1A. there are meme fans with golfball textures and 9001 blades but there's only so much air a 100ma fan can push.

I use a corsair AIO with a 120mm radiator but the biggest limiting factor is the pump which is bullshit and slow even still, my 6700k only goes up to 78C at full load as a function of the pump power being the weakest link in the loop.

>>1126151
Thanks anon!
My only issue is that the reason I was using water cooling in the first place in this build was the extremely confined space of the case (the thing is damn tiny) so I wanted to squeeze out as much cooling as I could in a very tiny area.

I'd say it's some kind of bridge rectifier but that can't be true because the is one in parallel to it.

M is the manufacturer's logo, not part of the part number. googling 'semiconductor company logos' didnt give anything resembling the pic.

Is that line-connected on the left? Optotransistor or optotriac.

there's nothing wrong with that

As already stated there nothing wrong with it. It's just that most woodworkers don't use dowels when joining wood at 90 degrees, so it's never an issue. Dowels are generally used for joining planks that will be side-to-side or end-to-end, for marking larger pieces out of smaller ones. In that case you can't have an exposed dowel, so you just never see it.

The real question is where do you get the nice contrasting dowels?

toggle switch...3 position pos. ground 220v.

surface mount push button plus behavior terms, momentary, tactile, NO, NC, etc

You're probably not going to be able to find an exact replacement.

That's a lot of connections for just a ccfl inverter. sure it doesn't do something else?

>>1125665
>>1125679
It's an inverter and LED status board. Thinkpad is my guess. What is the FRU number on the back?

>>1125778
nvm, found it. FRU41W1479, one of the variants for T61 (14") and T400.
I don't have the pinout of this one on file, I'd have to go test it off a live machine. Is there a specific pin you're looking for or do you need them all?

Print a picture of the statue actual size of small statue.
Draw a line 3/8" around the outside of the statue figure.on the print.

Is this really what you're expecting?

You end up with just a blob with a small statue in the center.

>>1125218
I was thinking more of a 10" tall elephant, so the 3/8" would actually be pretty thin. Beyond that, are you able to address any of the various questions?

>>1125116
No. It is, depending on your situation, a worthwhile alternative to living in a mobile home or shitty apartment.
A traditional Vardo or teardrop camper you can make with 5-20k of materials if you do most/all of the work.
The biggest issues are electrical and plumbing hookups.
Especially plumbing, since tiny homes are often built on trailers to get around building code size requirements.

And the crazies who pack everything in 100 sqft are crazy.
But a hotel room is only 325 sq ft average, and since you're doing it yourself you can do things they cant, like save on floor space by putting bed in a loft or murphy bed, or fold away table/chairs (which are confusing unles you know how they work).
So in some situations, eg theres cheap land you can't build "permanent structures" on, or you have family land, etc. basically same as a cabin innawoods where theres not enough trees and building codes have a minimum size.

But downside is while you can collect rain, no drain = no toilet. except terrible chemical toilets.

But again, as a concept, it's basically the same as living in an rv, which works out for some people.

It's a meme to buy one
>spending tens of thousands of dollars on 200 sqft instead of using that as a down payment on a real house
But if you build it yourself, it's a viable option for poorfags

An important note that usually isn't stated in these threads is that you probably can't get a job without an address.

Welding exhaust is not easy and can't be done with a cheap machine

If your exhaust has degraded to the point that holes are appearing; welding on that steel is a futile effort

you need a 2-way Stereo Passive Subwoofer Crossover
it has in and out for stereo speakers
at full range and a mono low range output for a single sub about 10$ on ebay

>>1124257
>bridging channels halves the impedance
bullshit.

Stereo amps are basically two independent mono amps in the same box.

The collector output of Right channel is designed for a resistive load, thus definitely not expecting to be grounded by another collector, like the left channel one.
This is very likely to happen if you're listening to a stereo track thru stereo wired INPUTS and parallel'd OUTPUTS.

On the other hand, if you bridge left+right INPUTS and left+right OUTPUTS, you will be getting twice more power, still at a matching load will stay at 4ohms.

To address your question, is your car amp fitted with a switch to invert (dephase 180°) the signal of one of the two channel ?
If if it's not you will have to get a dephaser to do that job, before considering to bridge amp's outputs...

you can do this but without cross overs as mentioned above treble will come out the bass speaker and bass from the mid/high speaker.

and why would we waste our time creating something which, being completely subjective, can be ignored out of hand?

if you want ideas, look through MLS listings until you find something that suits your tastes (which are probably shit, but they're yours).

Wouldn't he stop bleeding when he ran out of blood?

You need an Alaskan Mill.

It'll saw trees into lumber quick enough

Its just a couple bars and rails you attach to a chainsaw.

>>1123590
That's actually a neat idea, just like a guide that goes on the saw? Kind of like those carving knives you see for turkeys and shit that have the adjustable guide.

why does it have to be the stump? just cut a piece off the tree. the only way you're gonna cut that stump off with that tiny saw is working your way all the way around it and it's not gonna be a clean cut

You're forgetting that you need one or more lenses between the light source and LCD.

Also your LED needs to be as close to a point source as possible. Don't use a board with multiple LEDs spread out on it.

Put LCD on pic related.

>>1122824
Don't forget cooling. LCDs don't like to get hot. And since they work by selectively blocking light, they inherently generate heat. If you pass enough visible light through one to produce a large, bright image, it will get hot.

This is why large image projectors use DLPs (lots of tiny movable mirrors). The DLP doesn't block the light, it diverts it to a surface that absorbs it. That surface gets hot, but it isn't sensitive to overheating and can easily be cooled.

i would make a small room out of plywood and either put home insulation or if you can find it foam sheets.

Rockwool/Roxol types of insulation tend to be better for sound absorption - also beats eggcrates and their ilk.

Make a small studio like anon above suggested.

This. Anything else is a waste of money and won't work anything close as well.
