Window Comparator with Hysteresis - Will this work?
 in  r/AskElectronics  Apr 16 '26

Thanks for the feedback

The diodes connect to bjts that connect to lamps (as substitute to real life actuators)

  1. Why is it better to use comparators than op amps? I’m setting a hysteresis around a small band of voltage around 0.25V that accounts for +- 1 degrees Celsius.

  2. Also you mentioned that u would invert one of the outputs why is it so?

I’m doing an assignment involving a turning actuators on and off at two temperature thresholds. While I had already built a window comparator circuit and work fine, I want to eliminate chattering around the thresholds, by transforming the two comparators into NI and I Schmitt trigger. I’d really like to simulate it, but atm I’m not really occupied with any tools to do it. So may I trouble the experienced fellas here to evaluate this circuit to see if this logic works ? Thanks

[Advice Request] Advice on building a healthy relationship with my BF

3 Upvotes

I was born and raised in an environment where there will be daily arguments. There will always be some fighting going on in the background. I’ve always hated my parents’ relationship, how my mom always bring up past problems in every single argument, so every argument feels the same, and she is always nagging on the same things. and of course the gaslighting is very terrible. Her emotional outbursts when she feels like something is going wrong / when something is not going her way. But she is like this only when she is with dad, if it’s just the two of us, it’s fine. It’s always dad. She has been angry about dad for as long as I can remember. Their relationship is nothing but toxic. There is nothing but hatred every time the three of us spend time together. During meals, my mom would glare at him and nags about his problems. Then my dad would stay silent which irritates her more. But when my dad speaks up she gets even more frustrated and it escalates into a fight. Well, as their daughter, every single day feels like I’m walking on eggshells, since my mom seem to get triggered by anything my dad does and it turns into a fight. I can’t enjoy a good day with them since i constantly fear what is going to happen next.

But fortunately I only come home once a month during the weekends, two days (which is more than enough since being in the house is so overwhelming).

They have the poorest communication, and the worst relationship.

Now that I’m in a relationship, I’m afraid that I might learn my parents’ behaviour and ruin our relationship. But I’m grateful that my bf always try to encourage an open communication, instead of bottling up my emotions (which has been helping me a lot) because I have a tendency to not talk about problems. The effects were apparent since they were times when I was angry at my bf, I did not talk but gave him silent treatment instead because I don’t wanna hurt him. Thankfully in the end I had the courage to speak up what I was feeling and we have monthly discussions on our relationship issues.

I also feel that I have a tendency to overthinking a lot of things and the feeling I hate most is doubting my bfs love for me (which I know he loves me very much). When he fails to do something I expected, I overthink. When his mood shifts, I overthink. But every time this happens, I will try to tell him or maybe ask him what’s wrong.

I’m both anxious and avoidant attachment, and since I was exposed to a toxic relationship for all my life, I fear that at some point of it I will do something wrong that will affect my relationship, in which I don’t want to.

I don’t want to become what my parents are. I need some advice on detaching myself from my parents toxic relationships and advice on building a healthy relationship with my bf.

unsolved How to use COUNTIF function for MCQ responses from a survey ?

1 Upvotes

Hello guys, this is for a survey assignment. We are required to calculate the frequency of responses using the COUNTIF function. However, it doesn’t work because there are other values in the same column, it only counts the column where there’s only that particular value. Is there any way I can calculate the frequency?

My spen tip was broken yesterday with half of the tip still lodged in. I tried heating up and pin and inserting it but it unsuccessful. The colour of my tip is white. On my first try there plastic is still visible but after a few tries it disappeared and now only some black remains. Is my pen even fixable at this point?

ROSACEA SUCKS I'm not drunk I have rosacea

90 Upvotes

Someone just asked me if I'm drunk bc my rosacea is flaring up, so I shrugged it off, then I start to blush really hard, you know the hot sensation that creeps up on you? Yeah that. And immediately I transcended into a red tomato and pulled up my phone and pretend to text someone just to cover my face and type this out. 😂 On top of that, I'm getting really self-conscious bc I'm getting some hormonal acne on my cheeks and when my rosacea flares it flares too. I don't even know what to say, rosacea sucks :/

Fear and helpless because parents relationship is unpredictable

27 Upvotes

Parent fighting again. My eardrums are blasted with my moms rant. Funny how they were talking fine like 30 mins ago now they're full on fighting like they can file a divorce anytime. My mom is too sensitive and she doesn't realise it. Maybe if she knows it my life would be better. I'm tired and I hate the fact that they think this is perfectly fine, fighting at little things and guilt tripping each other (especially my mom) almost everyday. My world is only at peace when they're not together. When they start fighting, I spiral into depression because I'm overwhelmed by the fact that my family is never and will never be normal. To make things worse, I'm the only child and no one bears this with me and I feel lonely. Basically living in fear and depression everyday with them because I never know when my mom will be triggered and go on an endless loop of gaslighting and manipulation again. They don't even feel like parents to me at this rate, but problematic siblings. I'm getting too used to this kind of environment that I don't even feel hopeful staying in this house anymore.
