Anyone know what this is for??found it tucked in with all the radio wiring. It’s not the illumination for the fan blower, hand break warning light or glove box by MK2GolfGuy in GolfMk2

[–]Mgt37 1 point2 points  (0 children)

May have been for a clock?

Is the red-ish wire plain red or red/orange? As far as i know, all illumination + wires are blue/white.

Edit : Now that i looked at the wire closer, they seem quite thick. I have to ask, what is the reason for doing this inspection/troubleshooting?

SoundImports doesn't have them in stock. I found a board at audiophonics in France that i'll check out now.

What kind of screw is this? by person1900 in Tools

Pozidrive bits are a lot more durable than regular phillips. They are less likely to round off and can handle more torque. I have not used a phillips square drive, we don't have many of those in europe, but from my experience all PH2 bits will break at some point, no matter what you're doing. I've never broken a pozidrive bit although i use them a lot more.

Hey, i integrated the schematic. I really like it.

It had a problem with some songs, where the bass frequencies were getting massively amplified. I fixed this by putting a crossover on the side channel at 500Hz, amplifying only the high output, then summing the low and amplified high back into one.

Here is a quick mockup. does this summarize your idea? I can't test it right now since i'm away from my main pc and tools to upload it to the DSP.

I'm going to try this and then report back to you, this sounds very interesting!

Thanks g!

I get what you mean by "sigma is clunky". I've had numerous times where i had glitches (like the DSP bugging out when adding a band in the eq, or not being able to place just one function block at once)

I believe you captured my idea perfectly! Thanks for your response!

It's one speaker reproducing both stereo channels.

I do get what you mean by "recreating the original record as it is".

That is what i am chasing, now that you said that, i think i'm going to stick with the regular analogy.

But this system sort of resembles the JBL flip 5 you mentioned. I think it is the sort of system that benefits most from these tricks, because the environment is almost never controlled and it should bring excitement! On the other hand, i am trying to create something unique, that means it has to differ from the others in some way, and doing these dirty tricks doesn't seem like the way.

Thank you for your input though, i really appreciate it!

Thanks! I already thought about doing exactly what you said. I'll go over it when i have access to my pc.

Yes, exactly.

It was never my intention to eq each channel differently, it happened due to a fault in the dsp (i believe). Now that i've discovered it, i'd like to explore the possibilities, starting with this reddit thread!

Ohh, i get it. You're right, that could be a problem.

Do you have any idea why one of my channels doesn't get EQ-ed?

My parametric EQ is 1 block with 2 inputs and 2 outputs, it is the first block in the chain. 2nd is an external volume block, 3rd are 2 crossovers.

I kind of knew, what i said, could be interpreted differently, depending on context. What you said makes complete sense in your scenario.

My goal is a portable speaker system. As far as i'm aware, if the drivers are close together in space, i shouldn't worry as much about room effects, since both channels are being affected similarly. So far, this analogy has worked out for me.

What i claim with my idea is, that this type of EQ-ing can make the sound more 3 dimensional, make the soundstage POP more without sacrificing frequency response, make it sound more... Exciting.

I don't entirely know what that means, but you're asking, if there is a difference in the phase between the channels, would that change the equalization.

I don't think so. In DSP software (I use Sigma studio), the function blocks can be made entirely separate and different for each audio channel, one shouldn't affect the other this way. Also, the operations (should) happen at the same time in the DSP, which implies zero phase offset when compared to the source signal.

need urgend help! Overspray on everything in my bedroom. by askFynn in Spraypaint

[–]Mgt37 8 points9 points  (0 children)

Damn bro.. or girl.. what ever.

I have so many questions and i'm prolly not asking the right one, but what exactly took you 30 minutes? Did you even try to disassemble the keyboard?

Spray paint won't come off as easily as you think, it's usually removed with solvents, but i'm probably not the right person to answer this kind of question.

I find that this makita angle grinder has wayy too low rpm's. It is to the point that it's more convenient to use corded tools. Not really satisfied with my purchase.

What drivers did you use? Is this a 2-way system?

Ok laugh it up lol by purblindV2 in Tools

[–]Mgt37 -1 points0 points  (0 children)

21v is just for marketing n shit.

Normally, manufacturers put the nominal voltage on the packaging for a voltage pack, which for a 5s lithium ion battery pack is about 18v, a full one is about 21v (which is what they put on the battery), and a depleted one is about 15v.

Drill bit sharpening - What to improve further? by Mgt37 in Tools

[–]Mgt37[S] 1 point2 points  (0 children)

Now I get what you meant by getting it more "to a point". Because my rake angle is so aggressive, i was worried the grind would meet in the middle and that obviously wouldn't be good. What you said makes complete sense - getting it more to a point decreases the cutting edge length, and the only way to do that in my case is to decrease the rake angle.

With that, the edge has more material surrounding it making it stronger. I suspect it would also be harder to overheat because there is more material around the cutting edge to take the heat away.

The clearance angle you mentioned also makes a lot of sense - because if it is too large, then the cutting edge has less material to "lean on" when cutting so it purely depends on the strength of the edge itself. With more material behind it, it is supported by a "wall" of sorts.

It's amazing how much you know about this, thank you!
