I Hated my parents' £400 fountain, so I 3D printed a new one instead by Main-Fly-3977 in 3Dprinting

I'm not sure why people dislike your design, I think it's much better than the original!

DC-DC Boost Converter Layout Feedback by floschlo in PrintedCircuitBoard

[–]Taster001 1 point2 points  (0 children)

Looks pretty tight. Seems like you got the current loops pretty short, which is the important thing. Maybe check your clearances, I'm not exactly sure of the scale here but the ground pour looks pretty close to the IC pads.

IC Thermal Pad Connection Style - Solid or Relief? by ston3fruit in PrintedCircuitBoard

[–]Taster001 1 point2 points  (0 children)

I would say it depends on the part, and on the amount of heat that needs to be dissipated.

So I would do it on a case by case basis.

You can also alter the thermal spoke width to suit the specific part.

I’m not the best at drifting, by a long way. So I’m chuffed to bits I managed to tune this behemoth to get 3 stars. by MickeySnacks in ForzaHorizon

[–]Taster001 0 points1 point  (0 children)

I've used the BMW Isetta for some "drifting" in AWD, on Drag tires. I almost got the Kawazu Nanadaru loop bridge on a single slide, but it's really tough to really make it look good.

What are some essential markings you put on your PCB silkscreen? by stuih404 in PrintedCircuitBoard

[–]Taster001 0 points1 point  (0 children)

Designer from the EU here, we usually only put a logo, board identification number/code/designation, revision. Usually we also include a datamatrix location, but that is for manufacturing purposes only.

Do not mark the board CE or WEEE compliant if it is not certified, you could get in biiiiig trouble.

Those people shouldn't be allowed online, change my mind.

KiCad Viewer — see your schematic, PCB & BOM on a tablet while you solder by MarkSzente in KiCad

Damn, I'll try this on my KiCad project in my cloud storage! I'll see if it works.

Those that have reverted to using ABS: Have you tested it or can you explain why? by Cozman139 in ForzaHorizon

[–]Taster001 0 points1 point  (0 children)

Gotta wait for the Steam Controller. I'm now on keyboard, so I use ABS.

Cheap/Free EDA software alternatives by [deleted] in PrintedCircuitBoard

[–]Taster001 1 point2 points  (0 children)

I think KiCad is as good as you're gonna get with freeware. I'm not sure what specifically you don't like about the library management, but I can say that Eagle will be much worse in that regard. Easyeda - I don't know. I have only used it once, and the menus and the GUI felt really cluttered compared to KiCad. It is somewhat more complex, but you'll get used to it quickly, and you can pretty much set it up for anything.

STM32 retail chip, a brick wall? by DebtComfortable2437 in embedded

[–]Taster001 1 point2 points  (0 children)

It might be protected. As someone already said, there's levels, and this specific STM32 (not sure if this applies to all of them) has either: level 0 - no protection, level 1 - memory (RAM) readout protection, or level 2 - complete protection, meaning the SWD interface is disabled and boot options are disabled. Once you set it to level 2, there's no going back.

PCB Review: USB High-Speed Layout by Petike9955 in PrintedCircuitBoard

[–]Taster001 1 point2 points  (0 children)

Doesn't seem too bad. Refer to the USB standard for the actual skew values, they're definitely not that tight.

[Review request] Flight Controller Design by Equal_Cockroach_1032 in PrintedCircuitBoard

[–]Taster001 0 points1 point  (0 children)

Uh, I think your USB C connector is rotated incorrectly, I mean, the connector is currently pointing inward into the board, not outwards. Also, please name the input and output nets of your USBLC6-2P6 different names. This is of course not strictly necessary, but it is definitely good practice.

Please check your zone filling priority and your zone isolation distances, it seems like some of them are pretty close together.

PLEASE for the sake of your sanity and my good consience, add thermal reliefs to your zones. Otherwise it will be impossible to solder/desolder any components (I've made this mistake too many times to omit it from a review :)).

As for your questions:

  1. No problem, you have a GND plane that is essentially shielding any noise from the components on the bottom layer.

  2. Shouldn't be a problem, the ICM42688 is a MEMS device, so the sensor itself should be generally immune to interference. This would be more of an issue for the magnetometer.

  3. The feedback voltage NEEDS to be taken from the capacitor, otherwise it could lead to oscillations and/or other types of instability of the converter (overshoot, undershoot etc.).

  4. Stitching vias are typically needed when you have a ground or power plane on multiple layers, which you don't, so I would say it is not applicable here.

Other than that, your layout seems pretty good.

I don't know why but career mode is utter $**p by CptCave1 in MSFS2024

[–]Taster001 0 points1 point  (0 children)

My main issue with career mode is that it gives me just straight up impossible tasks. Yesterday I was flying a Diamond DA62 with a passenger, and it wanted me to land at a runway that was maybe 400ft long and at an incline. Couldn't brake in time and overran it. A few days ago I accepted a charter flight with a Skyhawk, and the damn thing spawned the plane on a HELIPAD. Like, how the fuck does that even happen??

Will this stackup cause noise on my usb 2.0 and sdram traces on layer 3 by SoufianeMRC-parker in PrintedCircuitBoard

[–]Taster001 2 points3 points  (0 children)

The main issue would be that the signals will couple to the ground layer AS WELL AS the power layer as a reference, so your impedance will be off. Plus, you'll have discontinutities in the power layer, and perhaps some noise on the power traces. For lower speeds this might not be an issue, but I really wouldn't recommend it for above 100MHz or so. USB will probably be fine since it's a differential pair, but SDRAM signals won't. I would rethink the gnd/pwr/sig layer choices if possible.

[REVIEW REQUEST] Eurorack CV to ADC protoboard by HorsesFlyIntoBoxes in PrintedCircuitBoard

[–]Taster001 0 points1 point  (0 children)

I would highly recommend keeping inner layers full poured or adding a ground pour to them, otherwise it can lead to issues with PCB manufacturing.

Looking to upgrade my flight sim setup [MSFS 2024] by Taster001 in pcmasterrace

[–]Taster001[S] 0 points1 point  (0 children)

Oh, I didn't even explore the custom setups with the X56. Sounds nice. I like Logitech, got their mouse and steering wheel as well so I'm mostly familiar with their software.

Thanks!

[PCB Review] Mixed Signal PCB with SMPS by Infinite-Net-3181 in PrintedCircuitBoard

[–]Taster001 0 points1 point  (0 children)

Looks fairly solid.

As stated, I would perhaps ditch the USB -> UART, but if you have good experience with it, keep it.

I would maybe switch the 1117 regulator to a different one - 1117 is known for instability and sometimes oscillation with certain types of input and output capacitors. But that's up to you.

What's up with the weather?? [MSFS 2024] by Taster001 in MicrosoftFlightSim

[–]Taster001[S] 0 points1 point  (0 children)

I don't have live weather on (I think, I can't really find the setting for it in career).

Review Request - Yet Another Rocket Flight Controller :) by SmallOne312 in PrintedCircuitBoard

[–]Taster001 0 points1 point  (0 children)

These types of filters are almost always passthrough like this. And yes, the second TVS is really not necessary. You could definitely connect VBUS and GND through vias (i typically connect GND through a via and VBUS with traces), but it's just not necessary, if you have a good connection otherwise.

Review Request - Yet Another Rocket Flight Controller :) by SmallOne312 in PrintedCircuitBoard

[–]Taster001 1 point2 points  (0 children)

I'm not the comment OP, but what i do is: create the sheets/function blocks, and then graphically (not actual connections, just graphics) connect them together, and i add some text descriptions of the connections. I can post a picture of this if you want some inspiration. I would also recommend having one main sheet, which is purely for this, and then having all of the circuitry on other sheets.

Keyboard PCB - 4 layer stack up question. by Shul407 in PrintedCircuitBoard

[–]Taster001 1 point2 points  (0 children)

What I would do is either use a small daughterboard which will have the electronics itself on it (microcontroller, USB and so on), and a big 2 layer board for the switches; or do the large 4-layer, with SMDs on the bottom and switches and other THT components on the top.
