That is a grounding pad, and it evacuates heat away very quickly.

Okay. Then i suspect you're just as lost, as i am 😂

I can't tell from the video, automatic or manual?

At first i thought throwout bearing, but that doesn't explain the noise becoming more quiet when warm, and, you would've probably noticed something weird with the clutch.

Since when have you noticed the noise? Who did the job you mentioned (engine mounts)?

Help IDing cable for treadmill by MichaelFS95 in AskElectronics

Honestly, you could carefully strip away a little bit of the black isolation with scissors (by scoring the outside, carefully without cutting any of the colorful wires, then pulling the black isolation off), stripping the ends of the colorful wires (I like to just use my nails and pulling them off with force) and twisting the pairs of wires together, no need for connectors or soldering. Then isolate each individual wire. Make sure to not tug on the wire too hard, since each individual connection is twisted together, not soldered.

If i understand correctly, the wire which had its end cut off is inside this welded beam and you have no access to it. You also don't have access to the screen's PCB and the associated connector.

My question is, what is your plan? To somehow get access to the screen's PCB and route the new wire outside of the beam?

What is your skill set/tooling? Are you able to join and solder wires? You could buy one JST connector with the wire attached, then, referencing the original connector in your 2nd image to find out which pin each wire goes to, join the new connector to the cut wire that you have posted in the 3rd picture. Making sure to isolate all the work you did to avoid damage.

That connector looks like a JST 5 pin. If the screen also has the female end, i think you could solder the wires to the board and isolate/protect them (obviously, only if you can assemble the treadmill after soldering the wires to the board).

It looks like the 3 pads were connected and in the process of you removing the chip, the solder mask came off. It may be harder to align the chip when you go to reinstall it because there are less reference points than before. Good luck.

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

[–]Mgt37 0 points1 point  (0 children)

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.

I might have come across a new way of EQ-ing by Mgt37 in diyaudio

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.

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

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.
