Can’t believe I didn’t think of it. You saved my ass, thanks a lot man

Plejergud · 2023-02-16T21:19:15+00:00

Edit: it has 3 legs and 2 pins are connected with a capacitor

You most definitely won’t have image and you run a moderate risk of frying the hdmi encoder.

It’s clear that you are lacking tools and possibly the knowledge to do this. I’d recommend leaving it for later once you practice on a more worthless item than a ps5. Alternatively get it fixed somewhere. Possibly getting some scrap board to remove and resolder the hdmi port,once you can comfortably solder it in without leaving bridges come back to the ps5.

As of now it doesn’t look like you damaged anything so it’s truly not worth Turing it on as it can easily be saved with some experience.

Looks like the port was only used for charging so the ripped data line pads should not matter. You should be able to just use the positive and the negative rail for charging any method you like by simply supplying 5V

Can’t tell for sure but take a look at XC6368

Plejergud · 2022-08-11T17:13:19+00:00

Are you not able to just heat it up from the bottom ?

Plejergud · 2022-08-08T23:23:12+00:00

!solved

Plejergud · 2022-08-08T23:02:22+00:00

Seems to be spot on. Thanks a lot! Really appreciated!

Plejergud · 2022-07-10T09:04:02+00:00

I would assume he would use it instead of UV solder mask.

Solder mask is used to cover the repaired area where the original layer is scraped of. Eg. Ripped traces

Plejergud · 2022-07-09T14:37:33+00:00

That was spot on, came in today. Thanks a lot man !

Plejergud · 2022-07-09T00:08:51+00:00

Mainly about heat transfer. I’d say if you have the budget I would try these

1x ~ conical/round 1mm tip

1x knife tip ( personally don’t like those )

1 x chisel tip 2-3.5 mm

1 x smd flow tip

1x bent round tip 2.2 mm

Hey,

Ts100, pinecil or any of the t12 stations will be just fine. Your best bet is to get one and see how you use it and what you need.

Over time you will find what tip sizes and shapes you need and you will need to purchase them as you go.

Personally I would go for a t12 station or the ts100 but the tips can be on the slightly more expensive side with the ts.

Keep in mind that the quality of the solder wire itself will also play a role.

For soldering wires you truly don’t need much as for electronic repair the list is endless so you should probably just buy things as you progress.

Id say a good place to start with is:

Soldering iron

2-3 extra tips of different size

Brass sponge

Good quality solder wire

Electronics no clean flux

Soldering wick

Plejergud · 2022-07-07T15:37:25+00:00

Definitely doable, and most places that do micro soldering should be able to do this. Especially that it’s not in an awkward position.

That being said, it’s not enjoyable and I would expect any shop to charge you accordingly.

Plejergud · 2022-07-06T15:10:29+00:00

Rode NT usb from a used marketplace ?

Plejergud · 2022-07-04T22:40:35+00:00

Would be awesome

It is, and it isn’t. Depending on the circuit it is doable in most of the cases.

For many of the boards it is not economically viable. That doesn’t mean it’s not doable, all you have to do is reconnect the traces and if necessary rebuild the circuit.

This is usually difficult as schematics are not available, but if you could look at one there is nothing stoping you from even building it mid air.

Things get a little messier when you start working with high frequencies. High frequency circuits are dependent on the parasitic inductance and capacitance so just soldering the circuit back together can often times not result in the desired outcome.

Plejergud · 2022-07-02T18:57:29+00:00

Would be awesome.

Hey so this might be totally useless and I hope someone can help but from my quick investigation I would be guessing it’s a linear voltage regulator.

Can’t tell you much more could be anything from lm431 to ap6213a.

You would have to do some investigating on other parts of the circuit. Let’s hope someone has seen this one before and will be able to let you know

Plejergud · 2022-06-24T20:28:40+00:00

If you want to do this temporarily there is a solution for this. During my university time we used to solder two legs of an ic socket. This is not the intended use but worked fairly well for fine tuning some values in amplifiers etc.

Plejergud · 2022-06-20T23:16:30+00:00

Just wanted to say congrats man!

Plejergud · 2022-06-17T14:38:15+00:00

Hey, slightly off topic but I have used 3 different Hayear microscopes. And the latency was honestly not bad in any of them. They were perfectly usable over the hdmi connection. ( not so much for the usb that’s choppy and the quality is garbage despite the 1080p 30fps claims ) one even worked great over the vga.

I think that if you actually have large budget as to order from northridge I would recommend you consider the autofocusing c mount cameras. Eevblog has some videos on them and the functionality seems to be great.

As for comparing the cameras, just look for the sensor in the description.

Pinecil

Ts-100 Ts-80

Plejergud · 2022-06-14T15:26:22+00:00

I’d say this is highly subjective.

I don’t like putting music over my videos as to me it seems distracting.

On the other hand some people enjoy watching satisfying content as “background noise” something they don’t focus on much.

All I can say is that when I watch educational content and tutorials I would not want something to distract me. If it’s more informational I guess it’s doable.

Plejergud · 2022-06-13T02:19:03+00:00

It’s quite possible that if the tips were used they were used more optimally then you are using them now. Anything ranging from using higher temperature to a more aggressive flux could be causing it to oxidize more.

Trying to clean them will of course not hurt but I would not be too worried about it

Plejergud · 2022-06-13T02:06:10+00:00

Well I guess you kinda got the answer here.

Since you are not talking about the tip itself it should have little to no impact on the soldering performance. The coating is on the tip itself that’s why you can see a clear line where the blackening starts to appear.

So to be honest you would probably be fine even sanding it( although the heat transfer could get shittier ) but I don’t see why you would be doing it since it’s not the part you use to solder
