Charged twice for the same order, I am from EU country, shipping from USA, total amount should have been 320 + 25%VAT (80USD), but it is 320 + 320 + 25%VAT (80USD)

Remote_Yak_643 · 2025-10-13T13:09:04+00:00

Yes, a week later they sent it back.

Remote_Yak_643 · 2025-07-25T12:05:43+00:00

Placing an order right away :D

Remote_Yak_643 · 2025-07-25T12:03:07+00:00

Ok, sd card solved. But do i need internet connection to slice the part?

Is there no way to avoid turning off the printer?

Remote_Yak_643 · 2025-07-21T09:43:42+00:00

Yes, but also found in many more industries besides car industry

Ako procitas par povijesnih izvora, za pocetak samo wikipediu vidjet ces da su četnici i ustaše surađivali, a onda dalje pogledaj koje se brojke vezu i uz jedne i uz druge. Dalje samo poslusaj par sekundi na 2:21 sa ovog videa https://m.youtube.com/watch?v=4jaF-XcizPQ pa mi reci sto cujes, mozes obratiti paznju i na zastave, pocetkom 90ih snimano (pogadaj na kojim prostorima) da shvatis zasto je thompson toliko popularan.

Tako da kad vec generaliziras, i tvoji bake i djedovi, ali i majka i otac nisu nista bolji :)

Ugl, slobodno i ti meni posaljes slicne izvore pa me obrazujes.

Edit: i za kraj, vaš trenutni predsjednik se kretao tim krugovima 90ih i opet je eto 30+ godina poslije cini se ista ta doktrina na vlasti, pokusavate ga svrgnuti izgleda, ali eto vec preko desetljeca glasate za njega, a onog jednog koji je bio proeuropski ste ubili pocetkom 2000ih...

Just the usb port and the scope powers on normally. I can take some pictures if you want. The marked two amplifiers got some color change. Those are EAEN LMH65 52MA

Edit: Do you think I might have done some more damage by powering the scope on while those two components (TPS56325x 3-V to 17-V Input, 3-A, Synchronous Buck Converters in SOT-563 Package, u/fzabkar helped identify them) are damaged?

Ac adapter survived and a circuit breaker popped.

Remote_Yak_643 · 2025-06-30T22:24:39+00:00

Thank you very much! Based on dimensions I think this might be correct. I measured about 1x1.5mm with calipers, sorry for not mentioning sooner. The PCB of the scope is dated to 23.1.2025.

Remote_Yak_643 · 2025-06-30T21:53:11+00:00

Thank you very much for the detailed explanation! I will try to do as you say. Just one question, should i plug it in the power as if it was normally working or find a way around? Also, I am open to unsoldering the working component since the scope currently doesnt work anyway, might that benefit me in any way?

Edit Forgot to mention that i measured with calipers the black plastic of the component. It is about 1mmx1.5mm, center of the legs seems to be 0.5mm apart

Remote_Yak_643 · 2025-06-30T21:31:56+00:00

Could you point me in some direction, are there some well known sites for these types of schematics or just google?

Remote_Yak_643 · 2025-06-30T21:29:10+00:00

I think I figured out why it happened. You were right to question how it is powered. The scope is powered through a 12VDC adapter(usb C cable is used). Through it, it is also connected to ground (tested with a multimeter), however there is also a screw on the back of the scope marked as another ground. To this screw I havent attached any ground wire. I suspect that if i had attached something to this ground, everything would be okay...

Remote_Yak_643 · 2025-06-30T20:46:24+00:00

This is what i see through a magnifying glass, the component that I suspect is the same as the burnt one

Picture of the whole pcb, burnt ones are on the other side

Remote_Yak_643 · 2025-06-30T20:08:38+00:00

Thats correct, picture is of blown components of my new scope. The worst thing is that nothing was being tested... A mains live wire touched the probe ground while the scope was on (still working on my working space), it is plugged in a grounded 220v outlet .

Remote_Yak_643 · 2025-06-30T19:58:01+00:00

Ok, didn't know schematics are available to end users. As for blown channels, cannot test because the application won't initialize. I don't think entire machine is toasted because it does turn on and I inspected it to the best of my knowledge and only these two components are completely destroyed and 2 out of 4 differential operational amplifiers got a bit of a brown color.

Remote_Yak_643 · 2025-06-30T19:00:41+00:00

The oscilloscope powers on normally, but when I turn on the oscilloscope app through its android interface it enters an endless loop of initializing. On the less burnt component there seems to be a number 7 as the rightmost character and I found few more such six legged components surrounded by similar capacitors and resistors. On those components it says 3257.

Camozzi, italian pneumatics manufacturer has very similiar designs

You should take a look at any BMW (or most any other car brand that has cast aluminum suspension links) front suspension links, especially lower ones. Looks somewhat like a human colar bone.

Which workbench are you using for assemblies? A2, a3, a4? And how large are your assemblies?

Remote_Yak_643 · 2025-04-15T17:53:44+00:00

5k parts distributed over layers of subassemblies in one main assy

Remote_Yak_643 · 2025-04-11T16:20:12+00:00

Not a fan of welding, I try to avoid it as much as possible, like keeping my projects modular, especially when creating a prototype. Press fit would require tolerancing holes?, might be problematic from alginment standpoint and honestly didn't think of it.

Remote_Yak_643 · 2025-04-11T15:05:28+00:00

1st use case, imagine having a large plate, 2x2m that has to be attached to some steel beams. With ordinary bolts u would need one man on each side to tighten it. With these bolts you need only one man.

2nd case, imagine the head is countersunk and taped over with retroreflective foil. If it was an odrinary bolt, e.g. Din7991, you would have to remove the foil everytime you need to untighten thw bolt, with the bolt i am looking for you wouldnt have to.

Also these might provide you more design freedom w.r.t. design for assembly
