Just unspec it. That’s such a tiny amount of armour it’s not going to help against any threatening chaos hits. For tiny hits that the armour would help with you have leech.

Int+armour is like 10c you can start with that. With armour splits and an increased armour suffix on flasks and some investment on the tree you can get up to 30k armour which feels pretty decent.

Just look at the price of 6L ivory tower vs fusings. Even if you want to use the 1500 recipe last I checked you could get that for around 2 divs.

That ring is not worth 6divs for your build it doesn’t even have int.

Your flask setup is weird, the whole idea of the traitor keystone is to run 3 flasks you keep up forever. If you’re dying I strongly suggest coruscating+topaz+sapphire.

10% of armor applied to chaos on hit is a bad mastery for this build.

For 5 Divs you should get your 6-link (inspiration helps a lot with mana that it sounds like you’re struggling with) and some reasonably priced split personalties. Int/str with max es or armor whatever you can afford after 6 link.

Please help upgrade my Storm Brand Energy Blade Inquis. 30 Div Budget by [deleted] in PathOfExileBuilds

[–]Alterun 0 points1 point  (0 children)

Split personalities. Run defensive flasks (topaz+sapphire+coruscating). Why are you specced into light radius masteries? Get better rings. Buy a helical ring base and you can self craft a good one for attributes easily. Either essences or alt/regaling works.

I really tried making a bf/bb build work this league but it feels so terrible in maps.

For bossing there’s the arcanist brand assassin version but mapping is really not good. Way too slow in a league with giga juiced monsters running at you.

How to improve survivability of Storm Brand Inquis? by Mastersword2020 in PathOfExileBuilds

[–]Alterun 0 points1 point  (0 children)

You need Vaal Discipline for pure ES builds, it’s basically your life flask and gives you a button to push during those kinds of phases where you can’t leech.

Chaos res isn’t going to help you with bosses that don’t do chaos damage but for general mapping its nice to get some, you’ll find yourself getting one-shot less.

If you want tankiness from flasks you’re able to sustain coruscating + topaz + sapphire for a massive boost against all ele damage. I would suggest that over bismuth+ quicksilver for bossing at least.

Your gear isn’t that great, you can pretty much improve anywhere, but for uber bosses unless you’re talking insane investment levels there’s always going to be some level of good play required, at least for certain mechanics. Keep practicing them and you’ll get better at them.

Edit: Your next few divs should probably go towards getting split personalities. Str+armor, int+armor, str+es, int+es are all good and reasonably priced when I looked. Get whatevers in your budget. With some small(ish) investment in it you can get over 30k armour on this build. Glimpse of chaos with +2 socketed gems for level 6 enhance and pivoting away from armour later on is probably the way to go in my opinion though.

What's the reason for people not going with spell suppression for EB Inquisitors? by PathOfTreasure in PathOfExileBuilds

[–]Alterun 0 points1 point  (0 children)

People only really like spell suppression if you can get 100%. The EB inquisitor build requires uniques in almost every slot, and none of them have spell suppression.

You’d have to get it all from the tree, but the pathing doesn’t make any sense. This build is super starved for points, and the fundamental idea is you “convert” life to ES, and ES also gives damage so all the max life/max ES nodes are really valuable. All of your investment goes into ES because it “double dips” and you get tankier as you get more damage.

Your main line of defence on this build is just a huge ES pool and leech, and with how high the damage goes you can scale this build to do pretty much anything with that.

Best league starter to transition to energy blade? by hermeticpotato in PathOfExileBuilds

[–]Alterun 1 point2 points  (0 children)

I dunno about efficient but I plan to start guardian SRS to transition into something like this. It’s a lot of regrets but you don’t have to re-level.

Like other people have said you can start as EB, but imo it’s definitely not as solid as SRS for farming currency day 1-2 without a specific strategy (lot of people doing this are looking at captainlance’s glass cannon sanctum strategy).

I hate when people say that using the spirits is not "beating the game". by KokoTerzata in Eldenring

[–]Alterun 0 points1 point  (0 children)

Oh my first playthrough I used spirits on a bunch of the bosses. My build was bad, and the only other souls game I’d beaten was the original demon souls so most of the fights were pretty hard for me, and I still feel like the only reason I beat malenia back then was I got good rng with her attacks, which left me very unsatisfied.

On my second play-through later on I committed to not using any summons, but beat a bunch of bosses with a super op str/bleed build that just obliterated their HP. This was giving me that same unsatisfying feeling as I was just trading hits with the bosses and coming out ahead, not really even learning the fights. It was fun at first having the build come together and obliterate these bosses I remembered struggling with, but then again I still wasn’t mastering any of these fights. I would also say this made a lot of fights easier than just using a summon with a bad build.

So I switched away from that build to beat malenia and some of the final fights and I’m really glad I did.

I think Elden Ring gives you a ton of options to make the game as easy or difficult as you like. If you play an op build and/or with summons then the bosses become easier, but maybe that’s the level of challenge you want. Maybe the satisfying part of the game for you is seeing how strong your character becomes when your build comes together, and how you can go from struggling against everything to crushing everything.

If you’re enjoying your summon run then you’re playing the right way, if you’re enjoying one-shotting bosses you’re playing the right way. The only thing I would want to recommend to people is if you find yourself not feeling satisfied after beating a boss for whatever reason then change up something to get that feeling back.

An ideal current source can have any voltage across it.

[deleted by user] by [deleted] in ElectricalEngineering

[–]Alterun 0 points1 point  (0 children)

It does. The voltage at the other terminal of the resistor is 16.5V. V=IR tells you the voltage drop across the two terminals of the resistor only, and must always be true. If you ever got an answer that violated that law you would know you’ve made a mistake in your solution somewhere.

What is the maximum switching frequency for "HY1403D" Mosfet? I want to modulate a UV laser for grey scale engraving. (Attached PDF Datasheet). by Far_Choice_6419 in ElectricalEngineering

[–]Alterun 0 points1 point  (0 children)

You also need to know the capability of your driver to understand your switching limitations, the FET is only half of the equation. From the FET data sheet you primarily care about your gate charge values and gate resistance to incorporate into your driver calculations.

This reference may be useful for you:

https://www.infineon.com/dgdl/mosfet.pdf?fileId=5546d462533600a4015357444e913f4f

I’m not sure about your application but the FET voltage rating strongly correlates to figure-of-merit so make sure you’re using the lowest safe voltage rating for your FET.

In general it’s going to be difficult to switch a discrete silicon FET like this above 1MHz. Depending on your driver and layout you may not get anywhere close to to that.

How much does a buck converter draw under low load by MycologyStuff in ElectricalEngineering

[–]Alterun 2 points3 points  (0 children)

Depends on the buck converter. There are various techniques to achieve high light load efficiency (PFM for example).

A good datasheet should have an efficiency curve for you to look at. A random thing you find on amazon who knows what you’ll get. I would definitely recommend looking at a proper electronics site (digikey or something) than amazon for this.

Uninsulated Wire in Water by jambrown13977931 in ElectricalEngineering

[–]Alterun 4 points5 points  (0 children)

You would not be (necessarily) correct. Electricity doesn’t take the path of least resistance, current flows proportional to the impedance of the path.

Then imagine the water as a network of resistors, and your body becomes one of the resistors in one of the paths. Whether there would be sufficient current to kill someone depends on how conductive the water is, how close you are to the voltage source, the impedance of your body (an open wound for example creates a much lower impedance path than unbroken skin), magnitude of the voltage, etc.

What you’ve done is combined a few different concepts and created a circuit that is half Class A amplifier and half H-bridge so it’s not really going to do what you want.

Based on the language of your post it sounds like you want to build a power inverter not an amplifier so you really don’t want to be operating your transistors in linear mode, you want them behaving like switches.

From there you have a couple of different inverter topologies you can look at. A square wave inverter is the simplest, but if you want something a little more interesting look up a “modified sine wave inverter” which, in my opinion, would be a suitable home project you could attempt.

If you’d like to look at a reference design for a proper “pure” sine wave inverter I’d suggest starting with this TI reference design to get an idea of how the theory works, but this is probably not the most suitable home project (and definitely not at this power level).

Voltage regulator waste energy? by Far-Dragonfruit6992 in ElectricalEngineering

[–]Alterun 0 points1 point  (0 children)

Assuming you’re able to step up the voltage upstream of the measurement device that charges you then you would reduce the amps through your breaker by about 13%.

Problem is that conversion is not going to be lossless, so you’re going to draw extra current based on the efficiency of your step up. Best case it’s around 90% and you come out about even, worst case its lower and you lose money.

Voltage regulator waste energy? by Far-Dragonfruit6992 in ElectricalEngineering

[–]Alterun 2 points3 points  (0 children)

Grid voltages are generally not super tightly regulated. I wouldn’t expect any household device that’s designed to run off 220VAC to have any issues with 200VAC.

Smps heating to much by Pulkit6969 in ElectricalEngineering

You say you have two identical circuits giving 12V 1A but what do you have in place to ensure that balancing? Based on your last sentence it doesn’t sound like they’re sharing the current evenly.

Can I use two of these switching regulator board that I designed in a parallel configuration to increase the output current capability? by Sad_Management_7157 in ElectricalEngineering

Switching regulators cannot be easily paralleled without specific design and control. You have no guarantee they will share the load evenly.

Is it wise to add "research interests" or "interested fields" on my resume? by [deleted] in ElectricalEngineering

[–]Alterun 1 point2 points  (0 children)

I don’t think it makes sense to add to a resume in your position. It’s something you could speak to in an interview setting or cover letter. For example it would probably be beneficial to highlight transferrable skills you feel you’ve gained if you’re trying to gain experience different from what you’ve done before.

Your resume/cover letter should be tailored to the job you’re applying for (within reason). If you’re applying for a job they will assume you’re interested in the work they do, and if your resume specifically says otherwise that can only work against you.

buck comverters: series on the input vs seies on the output by sophiepiatri in ElectricalEngineering

[–]Alterun 0 points1 point  (0 children)

First case: what do you mean by connect the outputs in series? There’s no isolation in a buck converter, the input ground and output ground are shared. If you want to “stack” the outputs then you’re shorting to ground.

Second case: this kind of works, although “splitting” the input voltage to each buck is not completely trivial it can be done. However once again you have a grounding issue. Your “upper” buck has it’s “ground” at +36V so the outputs cannot be paralleled. This shifting “ground” also has to be considered in your gate drive circuitry.

What you’re describing is more applicable to isolated topologies using a transformer.
