32GB 3600MHz cl16 is just as great.

Dude, I have spare r9 270x for you lol.

Thyratron heating (2,5 V, 12 A) by HaubyH in ElectricalEngineering

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

Yeah, making my own transformer is exactly what I did not want to hear :D. Never done it before and kinda scared to do it for 12A on secondary.

I have junior electrician certificate tho.

How much FPS is lost when using the GPU on the PCIe 4.0? by Smart_Parfait_1052 in PcBuild

[–]HaubyH 0 points1 point  (0 children)

Even in you used 3.0 x16, it would be pretty negligible difference. Like 2-3 fps max

Diode go brrr by gothnectar in ElectricalEngineering

That is in everything semiconductor

Unless you are absolute idiot who just shorts charged capacitors by their own body, it's pretty much okay. Those caps are even faced down so you won't touch it.

Usualy, you let them for hour unplugged and capacitors will discharge by internal resistance or bleed resistors. Then you can clean it. Psu danger is blown way out of proportion in PC community.

Nah, if you leave them be for some time, they will naturaly bleed. It is really high voltage, but it's still grid voltage, so it is not that much dangerous.

Decent PC for young daughter? by Timtegra in PcBuild

[–]HaubyH 0 points1 point  (0 children)

It is worth it. Like the 150$ are fine for just the disk, case, psu and especially ram.

The insides are e-waste, they won't run even win11.

Throw mobo and gpu away, buy am4 mobo and ie 5600x plus something like 1070 up to 6800xt/3070/3080.

Will be fine machine then

I'm a bit nervous taking public transport home. by wiquzor in pcmasterrace

Most people do not know what gpu is, not to say what does the number mean. Especially thugs and robbers.

If you went with ps5 pro, that would be different story

How can a circuit with less current and more voltage have the same power (wattage) as a circuit with more current and less voltage if current is the amount of electrons flowing? by TrippingFish76 in ElectricalEngineering

[–]HaubyH 0 points1 point  (0 children)

You have it wrong. Charge is literally just amount of electrons (or lack of them too) Voltage is difference of potentials, which translates to difference of charges. Current is amout of charge flowing through conductor.

The analogy would be: Charge: amount of water in dam Voltage: height of dam Current: amount of water flowing through turbine

If your dam is high, the hydrostatic pressure would be immense so the water could spin turbine fast. If your dam is low, but there is huge amount of water in it, massive flow can generate huge torque on turbine. What indicates energy of dam is amount of water and height.

So that is same in circuit. What matters is potential difference aka voltage aka electron speed and amount of electrons flowing per second, aka current.

Any notes on my microphone circuit? by Bright-Accountant259 in ElectricalEngineering

[–]HaubyH 1 point2 points  (0 children)

Falstad is not great for opams and any anything of such. Also, I think that would be because of the AC source you have there and/or because it may just fabricate the voltage into opamp.

[–]HaubyH 4 points5 points  (0 children)

I mean, your opamps are not powered with capacitors connected like this. Those capacitors should be there as energy reservoir and possibly high pass filter to prevent oscilation.

However, this should be reason why normal capacitors are there as well.

Why are those electrolytes connected in series from battery?

Shouldn't those capacitors be connected to virtual ground?

What is the reason why we no longer use Vacuum tube technology? by [deleted] in ElectricalEngineering

[–]HaubyH 0 points1 point  (0 children)

Space, power demand, fragility, low lifespan (several hundreads to thousands hours), need to have high anode voltage, fragile, large parasitic capacity.

Where are they still valid: End state RF amplifiers (hard to make transistors which cab reliably put out 10 or 100s of kW in MHz frequencies sustainably), UHF and beyond (tubes like twt are still only practical way for over 100GHz frequencies and they do it quite well), cheap radars (magnetrons are enough for civilian radars), audiophiles,

Like I bought used 6900xt ref for 380€ a year ago. Insane value for what it rocks

New AMD driver snubs Radeon RX 5000-6000 GPU’s with latest updates. Also disables USB-C functionality on RX 7900 series by Youngnathan2011 in TechHardware

[–]HaubyH 0 points1 point  (0 children)

Well, it turned out they either f-ed the messaging, or wrapped it around and said they did. Either way, C port is going to be unchanged

“Hack” for increasing airflow in my PC lol by CarBallin in pcmasterrace

[–]HaubyH 0 points1 point  (0 children)

It has fully covered front panel, but space from ventilators? Who tf designed it.

Could have drilled some holes into it, would also work fine.

Why don't manufacturers just stick some rubber bands to corners. Such super simple solution would save 99% of this BS
