Would you be willing to share how you make that work? I can't imagine living on my own for that much, let alone raising 3 kids. What does a weekly meal plan look like? Do you drive? What are rent and property values like in your area?

Edit: Just ran some numbers, and I can see how that could be possible, but it's dangerously lean. We shouldn't need to live like that. I commend you for making it work, but would like to say that you're definitely worth more than $20k/yr (especially with all those home improvement skills, but regardless)

Nor did I elect you king of what I'm allowed to enjoy. Go ahead and police people's thoughts if you insist, but don't expect to be included by people you willfully offend.

You're welcome to dislike something, but that doesn't mean you need to discourage someone else from liking that thing. You can share an opinion without making it sound like it's a sin against nature to disagree with that opinion.

Good to hear! Next step is to look at why it didn't fit. Where do dimensions need tweaked? Is the printer calibrated correctly and printing at 1:1 scale? I'm not sure how to recalibrate if the printer is the problem, but you could scale the whole print up/down when you generate the print file.

To test the printer, make a simple cube that's something like 1" on each side. I'd use 25mm for metric. Then, check how large the final print is. You'll want to check each direction since there are different stepper motors controlling each axis of movement, so each one could be slightly different

I'll second getting digital calipers to make things easy. I should really just buy a pair myself already, I've just been making do with a ruler.

FreeCad is another free option I don't see mentioend yet. It works but is frustrating to use because it's buggy and fights with you.

Generally, I think of 3D design like legos or scultping. You need to build pieces and "glue" them together. It's okay to have 2 objects taking up the same space too. If you can imagine 3D objects and how they fit together you'll find it a bit easier.

I hope your new diagnosis helps you. Learning more about how you think, what motivates you, and what holds you back can help a lot with choosing realistic and satisfying goals. If you keep at it, I think you'll figure out how to achieve something you can call success.

And for what it's worth, I don't think it's possible to be a failure, but I do understand the pain of defeat. Thinking more about it, defeat seems like the pain of wanting something, believing (correctly or otherwise) that it's impossible, and then continuing to hold onto that desire. It's the gap between what we believe to be possible and our expectations, not all that different from grief.

I think you'd need to start by getting them to admit that the heat is a problem without mentioning climate change. Don't use any of the buzz words they've been taught how to respond to. Just try to get them to have a conversation where they have to come up with their own answers.

In fact, maybe don't even start off with anything related to the topics they've been told what to think about. Ask about something they care about more directly that isn't on their party's agenda. You'd need to keep at it long enough for them to start understanding you're not their enemy, which could be anywhere from a few hours to a few weeks/months, depending on how deeply entrenched they are. Then, start trying to work towards the lesser issues their authority doesn't bring up often but has expressed an opinion on. Basically, you need to de-indoctrinate them.

If you can get them to talk about an issue without recognizing immediately that they're in danger of contradicting their chosen authorities, then slowly transition towards getting them to talk about more and more "dangerous" topics, you might help them to bridge that disconnect and start thinking critically about the key issues.

That all said, You'll have an easier time working with people who haven't been deeply entrenched in an authoritarian ideology. The less developed their beliefs, the easier it'll be to guide them towards thinking about their beliefs critically. That's one reason it's so important to teach critical thinking in primary/secondary schools.

logic will never convince them because they aren't arguing from a position of logic. It's about conforming to the beliefs required to be part of their tribe and/or protecting themselves from coming to terms with the harsh realities of climate change. It's reactionary against a challenge to their beliefs.

You would need to first convince them to consider that their respected authorities could be wrong. But within this reactionary mindset, being wrong is disgraceful. So unless they lose respect for their leaders or manage to shift away from believing fallibility is disgraceful, I don't know if they can be convinced.

 

Hello, I have a circuit that will need to return connected hardware to a default state if power is lost. The hardware can handle continuous voltage, so I'm thinking a simple solution would be to use a battery to provide that fallback power source. To avoid draining the battery, I'd like to connect it through a relay on the normally open contact and energize the relay directly from the main power supply on my board.

Do I need to look for anything in particular to make sure the coil on the relay I choose can sustain constant voltage for potentially months at a time without damage? Or, is there another similarly low cost and simple solution you'd recommend?

The circuit runs on 12VDC from a [Mean Well IRM-10-12 (specification), and the relays I have on hand are OMRON G5LE-14-CF 12VDC (specification). I don't see anything on the relay documentation that specifies a maximum duty cycle.
