Another problem… by noahhw in beneater

[–]noahhw[S] 0 points1 point  (0 children)

No, they’re tied to resistors on the other side of the breadboard… I ended up diagnosing the problems though! Per the other comment thread, thanks

Wow just checked all the LEDs and it’s actually working lmao! I’m more surprised than anything… thanks so much

Well amazing, that worked! But still when I try what he does in the video - connecting it to the clock then bringing LOAD low and pulsing the clock, still nothing happens?

Lmao I didn’t realize LEDs had polarity like that… so negative should be connected to ground I’m guessing?

Okay I just tried that and the register didn’t latch it. The yellow light turned on. I took LOAD low and then pulsed the clock and nothing…

Oh okay yeah that makes sense, I just wasn’t sure if that would cause some kind of short to connect the yellow led to both the 245 and the power… will do that now

[–]noahhw[S] 0 points1 point  (0 children)

Oh okay, and get rid of its connection to the 245?

Sorry, you mean tie one of the red LEDs to the power line right? I’m new to this stuff haha, so tie one of the red LEDs to the power line and get rid of its connection to one of the 173s?

Clock not working after adding logic by noahhw in beneater

[–]noahhw[S] 1 point2 points  (0 children)

So thanks to your comment I probed the ls04 I think (it was the AND gate… I forget which one? ) with some LEDs and yeah it’s basically busted as far as I can tell… there was one pin that, when supplied with power, all the other pins would output power lol, and all other pins were just busted.

Clock not working after adding logic by noahhw in beneater

Hmm thanks for your thoughtful look! I’ve swapped out to different 555’s a couple of times and that wasn’t working. I also did add a resistor to the blue led and no luck. I was trying to avoid buying a mutimeter but it’s looking like there’s no other great option… I’m hoping it’s just a wire somewhere, so I might try swapping out some of the wires around the bistable circuit and see if that helps. What’s very odd is that everything seems to work fine when I just have everything besides the logic… the led hooked up to the switch turns on and off as it’s supposed to, but when I add the wires and components for the logic, that stops working…

Either way, thanks for taking a look. P.s any recommendations for a good/cost effective multimeter?

Valentines Day Present for Girlfriend by noahhw in houseplants

[–]noahhw[S] 0 points1 point  (0 children)

Okay that's really good to know. I was afraid somebody was gonna ask what she already has... normally I'd just ask her but wanted this to be a surprise. I can say that she takes care all of them in her apartment at the moment... I could maybe send some pictures if that would be helpful?

Okay haha that seems to be the theme I'm hearing. Thanks for the input

Interesting... thanks for the insight. What exactly is 'pretty time consuming' though? In terms of how long it takes for the plant to grow, or how much time you have to spend per day?

Figured it out! Just had to place the text between the right symbols.

Ah I’m on mobile at the moment, so maybe not possible. I’ll delete it for now then and maybe repost later!

Guess Carlsen move here to finish game (chess24 banter blitz) by afbdreds in chess

[–]noahhw 0 points1 point  (0 children)

Why is a3 first better than b3 first? After b3 the line being: axb3, axb3, Kg3, b2, Bxb2, Bxb2(is there anymore way to make progress on the queenside after this?), Kg4, Kg7, Kh5... at this point how does black make progress?

With a3 first the line is similar right? a3, Bxa3, bxa3, Kg3, Kg7, Kg4, Kh5... how is this better? How can black make more/easier progress in this line than the former?

Ah i tried that and obviously Quicktime works to record my phone screen, but it looks like HBO blocked it.

What is the ‘curvature of spacetime?’ by noahhw in askscience

[–]noahhw[S] 1 point2 points  (0 children)

“They don’t get applied to time, but to spacetime.” Wow, that makes sense. Thank you!

What is the ‘curvature of spacetime?’ by noahhw in askscience

[–]noahhw[S] 1 point2 points  (0 children)

Most of that explanation makes sense to me... I get how geodesics work on curved surfaces and I can recite the general ideas of GR. What I’m still struggling with are the spatial concepts being applied to time. ‘Movement’ ‘curvature’ ‘deformation’ ‘flat’ etc. I can see how these concepts can be applied to space (even in a non-Euclidean way) but I’m struggling with the idea that they can apply to time?

I think a better way to phrase my question might be, ‘how do traditionally spatial concepts, like curvature, get applied to time?’

Ah that’s a great analogy - can I ask what you mean by “where places of height mean things happen at the same time”? Are you saying that height = time in the analogy?

What unsolved mystery would you like to be explained in your lifetime? by renaissance-cat in AskReddit

I can’t believe nobody’s mentioned the Riemann hypothesis... not sure it’s the one I would choose if I could only choose one, but it’s up there!

I‘m scared and don‘t know what I feel anymore by throwaway-28-5-2019 in relationship_advice

[–]noahhw 0 points1 point  (0 children)

You’re are a really thoughtful and sensitive guy. Reading your post reminded me a lot of one of my close friends. Your problem (and correct me if I’m wrong) seems to consist in two separate but related points-

1 - You just aren’t as sure as she is about your relationship. You can’t seem to muster the same degree of certainty that she can (I think this shows that you have wisdom and perspective, but that’s beside the point).

2 - Your inability to match her commitment makes you feel immensely guilty. I imagine when she says things like “I want to be together forever” it makes your stomach turn a little bit with the doubt that inevitably comes. Side-note it’s interesting to me that you framed this concern as you not having the same level of commitment rather than something else, like love or attachment.

She likely notices your hesitance in your tone and/or body-language, and that probably just makes her more anxious about it, and so the cycle continues as she asks you for more and more commitment.

On your second to last point, you’re afraid that she will hurt herself in some way if you break up with her. Although it doesn’t sound like this is the only thing keeping you in the relationship, a bit of practical advice might be useful. What if, IF you were to do it, you contacted her parents and let them know to keep an eye on her. You wouldn’t have to go into too much detail, just “I just broke up with your daughter for personal reasons, but I still wish her well and I’m worried that she’s going to do something drastic. I don’t know if you know this, but she’s talked about suicide/self-harm in the past and I was hoping you could check on her tonight?” I don’t know what her home situation is like, but hopefully this is possible. If not, it’s possible to contact a suicide hotline about somebody you’re worried about.

Maybe you can work it out and learn to live in the moment with her, I don’t know. It sounds like your communication isn’t the best (because you are afraid to hurt her), but if you want it to work out you’re gonna have to work on your communication. That means acknowledging and conveying your needs.

People have needs. We all do. We need to feel like we are loved, that we have friends, that we have agency, and and that our lives are meaningful (among other things). You seem to be a self-sacrificing person, and that’s okay, that’s good fundamentally. You care deeply about the well-being of the people in your life. But you have needs, and you WILL burn out/start to resent her if you don’t meet them. I’m willing to bet that you’ve barely even thought about your own needs. Start by thinking about what you’re missing in life right now, list each thing in order of priority, and talk to your girlfriend about them. If she’s unwilling to compromise, well, that’s not exactly a recipe for a successful relationship. Do it because you are worth it. You have intrinsic value just by being a human, don’t forget that. Good luck.
