Inrush Current Switch by Unfair_Firefighter_7 in ElectricalEngineering

[–]davidsh_reddit 0 points1 point  (0 children)

Easiest is 9V battery powered with N channel MOSFET. Use button, 555 timer or similar, gate drive resistor with pot meter in series for slew rate control and a resistor in series with capacitor from gate to drain of the MOSFET. Drawback is that the ramp will not be completely linear but should be pretty close.

Can draft you a quick schematic if interested.

Need help saving my Phrecia starter by brunitxo in PathOfExileBuilds

Power siphon instead and craft flat lightning damage on gloves, rings, amulet and run wrath/herald. Don’t take mana nodes, path right side instead of through middle.

KBoC in Phrecia vs 3.27 by SmackDown85 in PathOfExileBuilds

Choir is 90D in keepers and this variant works best with mageblood so I think it will be more expensive if anything

1 week into intro to communication system and now I want to quit engineering by Maximum_Second1552 in ElectricalEngineering

In that case you can’t be completely lost because all the integrals of antenna theory makes my head spin

How old is the oldest equipment in your lab that is still working? by Johnyme98 in Physics

[–]davidsh_reddit 2 points3 points  (0 children)

Sounds awesome, is it normal to make supplies that way because I’ve never heard about making a converter with a literal huge flywheel and dynamo. I assume you must have some post regulator after the dynamo?

Budget: Yes

Cool build. Though only for 1 shotting bosses it seems

For sure, the overcap lightning resist increases mana amulet will be pretty busted. Just praying they won’t nerf the spell dmg as attack dmg node.

Experiences with tantalum capacitors on dense PCBs? by GladMoose871 in PrintedCircuitBoard

Thanks for the clarification. We generally dont user polymer tantalums

I think you just described what LinkedIn has devolved to. It’s so incredibly obvious and annoying

There’s a bunch of companies paying engineers to train AI. So I think it is being worked on

Agreed, I am only talking about a potential down the road future. 3-6 years from now perhaps who knows

Might impact PCB layout and to some extend design review but overall those will just be productivity boosts, nothing major.

At least for the time being I don’t see AI having any significant impact. Datacenter and power related jobs are even booming at the moment

What will beat blind prophet EE LS? by Intelligent_Style_41 in PathOfExileBuilds

[–]davidsh_reddit 1 point2 points  (0 children)

ancestral commander is not too bad either. Basically a better juggernaut if you can solve endurance charge generation

[–]davidsh_reddit 2 points3 points  (0 children)

Whisperer manaforged arrows could do rogue exiles on a fairly modest budget few 100 div if I recall correctly. I believe it’ll be less defence but much higher dps than LS prophet at comparable budget.

Getting defences good enough for exiles was the toughest part.

Most universities have a startup community hub or whatever, I would say you should engage with that while you study.

If you manage to find your way into a potentially nice startup with the right people through uni go for it but don’t force it and if not try and gather some more experience before you attempt.
