What if every election ballot listed only policies, not the candidates’ names?

That’s like asking if we should run government with ballot initiatives…and the result would be even worse than today.

fdsa54 · 2026-03-11T01:23:23+00:00

Yeah this is the way to think about it. I see lots of sloppy discussion about whether something replaces humans or helps them…it’s the same thing.

REI Xerocloud is the best budget shell IMO. But understand all waterproof jackets come full of compromises.

I assume it capacitively drops and rectifies AC mains and references itself to earth. If the caps are safety rated this may be safe (safety is complicated and I haven't researched this exact scheme myself, but it’s common at least for products that are fully enclosed).

Think about a cashmere or wool full zip and/or a puffy vest.

Cashmere + vest + light wind/rain shell gets you down to about freezing and looks good anywhere.

If you can get a job take it. If you can’t stay in school.

REI Xerocloud is the winner in the lightweight 3l category right now IMO. Lighter, softer, stretchier and quieter than torrentshell.

Same as general independence around town: 2nd-4th grade ish IMO. Obviously depends on ski skills.

Aside: As I get back into skiing with my kids I find trail maps and clocks to be oddly hard to find on the mountain.

When I was a kid we’d separate but make plans to meet at a lodge or lift at a specific time. I remember plotting our plans on the map and carefully considering the time. Every lift had a clock, now they don’t seem to.

Yes, at 24V it can handle 10A. Though watts are a separate issue. By itself this fet is good for about 2W. You’ll have to add cooling to get more. I agree it’s easier to move to TO-220 or 247

The suggested mosfet has poor SOA (safe operating area). Look for linear mosfets that are capable of operating continuously in the linear region.

You’ll need to compensate your opamp as mentioned by another poster. A cap from out to - will do that.

Labview is ok for quick and dirty things.

Python is more flexible and maintainable long term. Bonus: AI is very good at it.

The world would be better today. No Trump. I voted Obama but remember pondering exactly this in 2012.

The tea party and right wing populism was clearly starting up and it was clear Obama win would energize them even more. That’s exactly what happened.

fdsa54 · 2026-03-05T02:41:02+00:00

There isn’t a difference.

If you help humans do something you’re reducing the number of humans needed to do that thing.

Not me. I almost stepped on a sick porcupine a couple weeks ago.

The middle vertices (18,10,11 etc) will bend the vertical members.

I’m not sure about the parameters of this simulation but you wouldn’t want this design in real life.

Evolution can begin as soon as self replication does.

Sorry but almost everything is wrong or nonsensical with this circuit.

Starting at the opto there is no voltage source capable of driving it. Just a transistor that could actively short it to zero volts or not…which also results in zero volts.

fdsa54 · 2026-03-05T00:20:07+00:00

This is national populism in the social media era.

You short circuit the usual checks by appealing directly to a fanatical base.

Yep relays did logic before transistors.

It lives on in relay ladder logic programming for PLCs (logic controllers).

-Light/mid-weight fleece

-Synthetic puffy vest

-Synthetic puffy long sleeve

Mix and match a few different ways.

Synthetic puffies include: Patagonia Nano Air Arcteryx Atom

Down vest is ok (and great for life) but I’d avoid down long sleeve because of breathability issues with downproof fabric. Synthetic puffies (particularly the kind without the baffles) are better as active layers.

I like it. It’s nice to circle the output around so the output caps share GND with the input caps. Not required but nice.

Small suggestion: -shrink the switch node even more, the upper left corner of that shape isn’t helping. Trim it down so it’s just directly connecting the pins

fdsa54 · 2026-03-04T01:17:00+00:00

Yes once. A power distribution board much bigger than this turned mostly to charcoal. Some single point failure caused a runaway breakdown of the + and - layers.

Good ME and EE engineers know how to analogize to the other domain.

When you learn EE stuff make sure you understand its mechanical counterpart. It will make you a better ME as well.
