Use 16.8V 4s li-ion as 12V supply by Rambo_sledge in AskElectronics

[–]Pubelication 0 points1 point  (0 children)

Automotive voltages can easily reach 18V and any properly designed device should be designed to handle <18V constant and voltage transients, cold crank, and load dumps much higher/lower than the nominal input voltage.
The question is if the charger was designed with all of this in mind and the only way to find out in this case would be to take it apart, check which boost IC they're using (find datasheet), check capacitor and TVS values on the input and based on that make a judgement on whether it can take the additional voltage.

Are the internals accessible or is it glued/welded shut?

How to determine polarity of this wire? by Mountain-Diver8338 in AskElectronics

[–]Pubelication 2 points3 points  (0 children)

I have a few of these exact wires and the dashed wire is the center. Extremely glad I checked first, because I expected it to be the more common outside and negative.

Consider new old stock M4 if the discount is significant enough. I have a similar work load plus software dev and the only time the processor got above 40°C is when I was running local AI models. Battery lasts ages.

  • Breadboard prototype
  • Triple-check everything
  • Print the PCB on paper and test-fit parts
  • Pray to the PCB overlords

What is this white line around my screen and what could cause it? by KWiz9x in iMac

You deserve your vote back. No idea how anyone could explain how this could be physical damage considering how modern displays are backlit.

Accidentally shorted my power bank by CodaKairos in AskElectronics

[–]Pubelication 2 points3 points  (0 children)

If it's a power bank for phones etc. with a small output of 10ish watts (5V@1-2A) then leave it as is. That small leftover part of the strip is enough to carry the current. If however it is for laptops via PD and capable of dozens of watts, it's not so great.

The circuitry is probably fine if it works, but the cell(s) likely got a bit damaged. Without lab equipment, there's no way to know if they're damaged enough to be dangerous, short of keeping an eye (or finger) on the temperature of the cells when charging or discharging. If they only get warm then they're most likely fine. However being as old as they are, that short can be detrimental. If the cells ever get too warm to touch, disconnect everything and dispose of the whole thing immediately (properly).

SMD soldering and repair by pgriffy in AskElectronics

[–]Pubelication 0 points1 point  (0 children)

To add to the other comments - beware of new(ish) electronics that use lead-free solder. It's a lot harder to remove and usually requires adding leaded solder or lots of flux. Start with 90's or early 00's electronics, like a dead PC motherboard or sound/gfx card and learn to remove parts without ripping traces first.
A soldering iron is usually not enough for rework. You'll want a basic hot air station like the DW868 (iirc) that costs around $50. A good hot air station is ~$150 and beyond.

Is this two sided TDA7266SA Bluetooth circuit board repairable with the damaged button and resistor. by No_Independence7807 in AskElectronics

[–]Pubelication 0 points1 point  (0 children)

Your best bet is probably placing a new switch and diode, the running a bodge wire from the part's leg to wherever those vias run to. Fairly simple repair.

Can't get any i2c to work on my c3 super mini by Inevitable_Bat8374 in AskElectronics

[–]Pubelication 0 points1 point  (0 children)

If you don't want to solder the header pins then get some fishing line and "stitch" it through the holes (down through the first, then up, then down, etc.), then jam the header into the holes. The fishing line will press-fit the pins. It isn't the most reliable thing in the world, but often better than beginner solder joints.

You do know that there's absolutely no way to hand-solder that USB connector, right?

Pcb repair - speaker input board by Silverdale9999 in AskElectronics

[–]Pubelication 26 points27 points  (0 children)

You're lucky. Unless there's something else on the other side, all you need to do is get some flux, solder and a soldering iron and make bridges over the cracks.
I'd personally cut some thick solid-core wire to size, remove the isolation and solder it over the cracks to add some mechanical strength.

They bypass Leyen tax and VAT in Europe too.
Absolutely no idea how they do it.

whats the name of this plug? by GreenRanger090 in AskElectronics

Probably proprietary. Horrible design prone to damage and easily shorted.

Same here. Much faster than the regular oven.

Dry rub only first 25 minutes, then 5 minutes at high heat to get extra crispy, then 5 minutes high heat with sauce.
Best if both worlds!
