So, you make a PCB with a zillion cap filter bank. How effective is that?

Re: What do you think of this review? [New product]
Saw that yesterday. Blinked a few times, especially after, as I'd assumed, it didn't do much. Then I wondered what brand most of those capacitors are, and if those failed, how many people would figure out that the product was no longer working, at all...
Hope nobody here has to recap one of those!
You know there's something wrong when you open up a PSU and are glad to find Teapos.
Why I don't buy cheap cases!

I figure you cannot turn the computer off with one of these?
It would take a while, and inrush would be pretty steep as well.
I wonder how it's better than say a 3v, 5v, and 12v, nicad pack?JimComment

Kinda reminds me of a bug zapper I made back in high school.

It's just a bunch of caps!
Cross-shaped vents - hope they're Nichicon and not something worse.Comment

Re: What do you think of this review? [New product]
The caps could be aqueous electrolyte Nichicons, e.g. HE, HD, HM, HN, HV. I have serious questions about whether PC P/Ss can drive that extreme a capacitive load and still be stable (not oscillate). The generic P/S type spec (e.g. ATX) should indicate how much load capacitance on each output a P/S designed to that spec should be able to handle. That box looks like it will exceed that spec by an order of magnitude or two.PeteS in CA
Power Supplies should be boring: No loud noises, no bright flashes, and no bad smells.

Any idea if those caps will bleed fully once turned off? A good filter bank can retain charge for years.Q6700 @ 3.6 GHz

Re: What do you think of this review? [New product]
Erm, that thing would seriously overshoot the max inrush current the ATX PSU units are designed for.
That is one of the reasons the DFI Expert mobo has problems with some PSU's, too much inrush current at power on..."The one who says it cannot be done should never interrupt the one who is doing it."Comment

Re: What do you think of this review? [New product]
There are coils visible, those can easily limite the inrush current ot the allowed level. There is nothing magic on that. Any VRM unit i have seen has this inductor to acomodate ATX spec. But i think that this device is to oversized, and i doubth that they used anything high grad caps. Ipersonally would use less caps but from superior quality and ESR. Furthermore i would make the power cord after the box as short as posible, as anything else will lessen the benfits. The VGA booster should be concected directly to the GFX card, without any cable.Comment

I have recently purchased a Lenovo ThinkBook Plus Gen4 Twist with Dual Screen. Here are the links for the product information:
ThinkBook Plus Gen 4 (13″ Intel) | 13.3″ & 12″ Dual-Screen 2-in-1 Business Laptop | Lenovo UK
However, somehow the serial number and the product name is no longer showing under the BIOS, Windows 11 or Lenovo Vantage.
Strangely the laptop's under cover does not show any information about the Make, Model, Type or Serial Number (No sign of tampering but no labels etc...). I am not sure what to do.
I do not have access to the original box...06-21-2025, 11:09 AM -
Has anybody tested this product? Posting this question on a Facebook tech group I'm in got a few responses like "that kind of thing corrodes the tips" and "just using normal solder paste is much better" so I'm not looking for generic responses like that, but rather, does anybody know for certain whether this exact product is good or bad for soldering iron tips?

I'm designing an ESP-based WLED controller board for WS2815 12V LED strips, with a primary focus on energy efficiency.
To minimize power consumption, my goal is to completely shut down the system when the LED strip is turned off.
However, the current buck converter powering the ESP module draws about 8 watts even when the LEDs are idle, making it unsuitable for low-power operation.
I am using below components:- Buck Converter: TPS562201 (12V → 5V regulated)
- Microcontroller: XIAO ESP32-C3 (with built-in USB-C)
- LED Strip: WS2815 (12V digital LED strip)
- Switching

I need BIOS for an XMG Core17 Product ID: XCO17E20, Mainboard GK7MR0R_v1.1_10L. When the power button is pressed, it flashes briefly and the device tries to start briefly, but goes off immediately. Battery is charging.
I have tested the BIOS "Monster Tulpar T7 V20.2 Bios Dump" from the startrek post, but it does not work and the behavior is the same. Here is a backup from my device.
Can anyone help me?

I saw this on
“How do they do it “
The laser was measuring the diameter and the height of the product and the weight of the product and it was a straight line laser light across the the conveyor belt ( this is all that was shown in the video clip of the laser that was used )
What type of product is this that can do this
I want to thank anyone that knows what of laser this is
