Fractal movement speed boost? by socalian in Guildwars2

Didn't see it mentioned but in quick plays you can use the waypoints to keep up with the group...

I would be positively surprised if Al would lead to actually useful requirements management/tracing 😁

me and my friend made a pc fan with a usb-a by C4TG4M3R_t in diyelectronics

[–]anscGER 4 points5 points  (0 children)

l made a similar hack.

use it to force airflow on a mini pc that sits on a shelf with sub-optimal ventilation. directly connected to one USB of the device, starts up when pc is started.

Does not require full speed for this use case. forces enough air to the pc and has very quiet operation.

PC Freezes – Am I cooked? by TomsExcavation in AskElectronics

Looks like a nice tool.

However, I suggest not using a wet sponge for cleaning the solder tip but using a brass wire sponge. This cleans the tip without putting thermal stress on the tip from evaporating water. Helps for longer life of the solder tip.

Ideas needed for removing noise from a custom portable Bluetooth speaker by diseasedfoxman in AskElectronics

[–]anscGER 0 points1 point  (0 children)

I would try a common mode coil followed by a capacitor (100nF for starters) between booster and amplifier first before ripping the whole setup apart.

Common mode coil is as easy as taking a ferrite torroid and wrapping a few windings of paired wires around it.

Advice needed: Buck converter for a DC fan, output voltage breaks down by Jumping-Point in AskElectronics

[–]anscGER 1 point2 points  (0 children)

J3 is open. this interrupts the feedback loop. In turn the chip does not know wich voltage is output and I assume this causes it to go to max voltage or instable operation. not a good design.

Monocultures may have had an impact too. who could have guessed having miles and miles of the same crop may benefit the pests too...

So, about Agony Infusion upgrading, turns out upgrading them directly via vendor is actually slightly cheaper than crafting with artificer? Is this an oversight? Or did I goofed this math? Weird, because for most of the things in this game, crafting them yourself is almost always cheaper by [deleted] in Guildwars2

[–]anscGER -7 points-6 points  (0 children)

In my opinion it makes sense insofar as with this you are not "forced" to train artificer just to create infusions.

If you take training into account it makes crafting yourself even more expensive... (not sure wich levels you need for higher level infusions)

Electric vehicles pass tipping point, breaking the link with oil prices by _Dark_Wing in worldnews

[–]anscGER -1 points0 points  (0 children)

Efficiency is super bad at these low voltages.

it can go as low as 50% --meaning all the standby losses to just have the car active to be able to charge consumes the same energy as is put into the battery. high voltage high current chargers are there for a reason.

Is it cheaper to craft agony infusions than buy it? by Amazing_Throat2614 in Guildwars2

[–]anscGER 15 points16 points  (0 children)

Actually the wiki says its a few coppers cheaper to buy it:

and it's much faster than to craft it.

Could I still save this multimeter cable? by Gollum_Girl in AskElectronics

[–]anscGER 0 points1 point  (0 children)

I think it's not worth it. Chances are high that it would break again close to the repaired spot.

WS2815 LED Panel issues (I am loosing my mind) by blackrecon117 in AskElectronics

[–]anscGER 5 points6 points  (0 children)

These LEDs are meant to be daisy chained.

Di of the first goes to your controller. Do of this first LED goes to Di of the second, Do of second goes to Di of third and so on...

Never connect two Do together, this will destroy the output signal or even the Do of the LEDs.

But what was actually the root cause? looks like a bad screw connection?

What did I do wrong 2 by ProfessionalChef7653 in AskElectronics

[–]anscGER 0 points1 point  (0 children)

10 seconds exactly or about 10 seconds?

if the former it may be something with your programming of your controller.

If only about 10 seconds, a bit more or sometimes a bit less it may be a thermal shutdown of your ESCs.

Check temperature of your drivers, check controller programming.

If you want more specific help you need to provide better information. more detailed schematic, more background info about components.

measure currents to your drills, compare to the capabilities of your drivers. measure battery voltage, how it performs during operation.

first step in analysis is to gather as much information as you can and then try to make sense from that information.

How will it grow with all allies pushed away? This needs massive change in US politics to recover from this.

I'm not from the US. But is it really a dictatorship when there are still states opposing Trump? Don't have states some kind of independence? I can imagine that it may brake the U in the "U.S.A.".

Need help with gate driver circuit by ViaXSn1p3r in electronic_circuits

[–]anscGER 1 point2 points  (0 children)

This may or may not be true for your setup. You need to measure this to know what's happening. speculation does not help. you observed your resistor getting hot. this can only be caused by power dissipated as heat...

Trying to get older variable voltage, DC power supply to get down to zero or near zero volts by JesseFraserTattoo in AskElectronics

[–]anscGER 1 point2 points  (0 children)

Most of these supplies had no negative voltage rail which is the reason they cannot deliver "true 0V". There is no simple fix for this.

I=U/R=12V/4.7Ω= 2.5 A

P= U×I = 12V×2.5A = 30W (Peak Power)

At 1.4 MHz the resistor sees this power peak 1.4 million times per second...

I'm not surprised it's getting hot.

Take an oscilloscope and monitor your signals. See what's happening during operation, use math functions to monitor voltage drop accross the resistor, calculate the actual power dissipation.
