RE:yeast slurry
There are guidelines and calculators for yeast pitching. I've used the one on Brewer's Friend. Some brewers are very scientific and numbers oriented, others take a more seat of the pants approach. I've always just scooped the slurry, put it in a jar, and re-pitched when I needed it. If your method works, it works.

Built a scientific calculator from scratch: custom PCB, custom FPGA CPU, hand-written machine code
I built a scientific calculator from scratch: custom PCB, custom FPGA firmware, and a CPU I designed myself in Verilog. The physical build: a custom main board and keypad PCBs designed in EasyEDA and manufactured by JLCPCB, an Altera Cyclone II FPGA as the brain, an LCD display, battery with charging circuit, and two ROM-flashing connectors on the sides to update the firmware. Under the hood it runs a nibble-oriented CPU I designed specifically for BCD arithmetic: the way decimal calculators should work internally. I then wrote ~4K of machine code implementing the full set of scientific functions: trig, logarithms, complex numbers, statistics, all verified to 14 significant digits against a dedicated test suite. The full stack: Custom CPU in Verilog: Harvard architecture, 12-bit ISA, 8 registers, hardware fault detection Hand-written microcode assembler in Python Verilator + Qt simulation framework for development and debugging Custom PCB (EasyEDA / JLCPCB), battery, charging circuit, 3D printed case The finished device is sitting on my desk. Live WebAssembly demo (runs the actual Verilog + microcode in your browser): https://baltazarstudios.com/files/calculator-d/Calculator.html Write-up: https://baltazarstudios.com Source: https://github.com/gdevic/FPGA-Calculator Hackaday: https://hackaday.com/2026/05/13/build-the-cpu-then-build-the-calculator/ Happy to answer questions about the PCB design, the FPGA setup, or anything else. submitted by /u/gdevic to r/electronics [link] [comments]

Designed a nibble-oriented CPU in Verilog for a scientific calculator where other CPUs wouldn't cut it
I designed and built a scientific calculator on an FPGA, using a custom nibble-oriented CPU I wrote in Verilog. Then I wrote ~4K of its machine code that implemented a large set of operations you'd normally find in a calculator. All operations are verified against long-doubles with a dedicated test suite. The calculator uses BCD arithmetic: one decimal digit per 4-bit nibble. Standard byte-oriented CPUs fight that layout constantly. This CPU has 4 bits as the natural data width, memory is nibble-addressable, and walking through a 16-digit mantissa is just a loop. What I built: Custom nibble-oriented CPU in Verilog: Harvard architecture, 12-bit ISA, 8-state FSM, 8 registers, hardware stack guard with a FAULT state, interrupts, ... Two-pass assembler in Python (~700 lines) Verilator + Qt simulation framework: same Verilog runs in simulation, GUI debugger, WebAssembly, and on real FPGA hardware CORDIC for trig, BCD arithmetic verified to 14 significant digits Scripting language on top of the microcode for adding more complex functions Custom PCB (EasyEDA / JLCPCB), battery, charging circuit; 3D printed enclosure Synthesized on a Cyclone II EP2C5. The finished device is on my desk.

The smart guys are intensely debating how to solve what appears to be a complicated problem, and the character usually considered an average dude solves the problem immediately in a simple manner right in front of them.
Phineas & Ferb: Phineas, Ferb and Baljeet finding out a puzzle where they have to guess the exact number of jelly beans in a jar in front of them to go through a maze. They immediately whip out calculators and start debating the mathematical formulae they can use for this. Buford, who's watching them and getting annoyed, casually walks up, gobbles all the jelly beans, and types zero into the computer, allowing them to proceed. Breaking Bad: Walter White and Mike Ehrmantraur having an intense long discussion about how they can build a complicated scientific bomb to wipe out the encrypted laptop of Gus Fring that could expose their meth manufacturing business, during which Jesse remarks they could just use a magnet, which they realize was a much easier solution. submitted by /u/SatoruGojo232 to r/TopCharacterTropes [link] [comments]

[New Updates]: My (22m) gf (23f) is secretly visiting my abusive parents with our son (3m) and doesn’t understand why this upset me. We had a huge fight, and I don’t know what to do now?
I am NOT OOP, OOP is u/hellshealth Originally posted to r/TwoHotTakes + their own profile Previous BoRUs: #1 [New Updates]: My (22m) gf (23f) is secretly visiting my abusive parents with our son (3m) and doesn’t understand why this upset me. We had a huge fight, and I don’t know what to do now? Thanks to u/soayherder for suggesting this BoRU Thanks to u/aaryanhere for letting me know about the latest updates Editor’s note: removed older relevant comments for space in this latest BoRU Trigger Warnings: neglect, past childhood trauma, emotional manipulation, mentions of child abuse, betrayal, possible parental alienation RECAP Original Post: March 3, 2025 I didn't have an easy time growing up, my childhood was so fucked up that I sort of just put it all in a mental box and left it at that. Needless to say I left my parents as soon as I could and then went no contact and haven't seen them since. Theres several reasons I went no contact and she seemed understanding enough when I told her that I didn’t even want to tell my parents about their grandson. I don't want my son around these people, I don’t want my girlfriend around these people and above all I would never leave any child alone around these people. My girlfriend doesn’t know about what exactly my father did to me and my sister, but I also feel like she doesn’t have to know in order to respect my wishes? Yesterday my sister texted me a picture of our parents dog in the background was my sons shoes. Our mother uploaded it on FB, where I have them blocked, but my sister recognized the shoes though mainly was concerned about them even having a kid over. My gf and I both work, she only part time, but we always have someone to watch our child, either my sister or my gfs family, so it’s not like she had to bring him there to have someone watch him. This was a deliberate decision that she should have made with me. I talked to my son about it and turns out he’s been there several times unsupervised, alone with my father. Apparently nothing happened, but I was understandably angry and confronted my gf as soon as she was back home, which of course lead to a huge fight. She left crying and went to her parents’ house and later her mother came to pick up my son which I refused, which lead to a fight with her mom too. My gf texted me, asking to talk later today and I know I can’t keep my son from her (I also don’t want to) but I don’t want to go into our conversation unprepared, so any advice is welcome. I also feel betrayed and still very angry and I'm honestly ready to break up over this, but my son is very upset and anxious because he heard our fight and I'm just at a complete loss and don't know how to handle this. Update: March 7, 2025 (four days later) First of all thank you for all the comments and input. I didn't feel like I could even think when I made my initial post, so it was good getting different perspectives. This will be a long post, but I’ll put a tl;dr at the bottom. I did write that my gf and I would talk that same day I posted but we didn't because I needed to sort myself out and I think she did too. She's been avoiding me ever since and requested we talk at her parents place, but I didn’t want that so we didn't get to talk until yesterday while my son was at my sisters. Apparently in September last year my mother reached out to my gf on FB asking how me and my son were doing. My mother is a very intelligent woman but highly manipulative. She convinced my gf to visit them because my father is ill. My gf said she didn't tell me because she knew I’d say no and she wanted to see what kind of people my parents were. She brought our son but didn't leave him alone at first, but their visits got fairly regular and she became comfortable with leaving him with my parents. He seemed fine, even seemed to like it there, so she didn't feel like he was in danger. The first time she left my son fully alone was when she went Christmas shopping. I think from what I had told her about my childhood home, she expected a house of horrors but according to her the place was clean and fixed up, the dog was healthy and my parents were nice. The thing is that she knew "something happened" to my sister. I never told her what happened to me which I now see I probably should have done. She doesn’t see predators everywhere like I do and when my son didn't report anything negative she saw no issue taking him and leaving him there. Its pretty clear that she doesn’t know anything about abuse and what it can look like. I don’t understand how she could think shed be able to spot the signs with this little knowledge. My father has been in contact with children most of my life and while I don’t know if he’s done anything to them, my sister always said he knew how to make children feel at ease. Both my parents are very methodical and calculating so I don’t blame her for believing them but I blame her for not discussing this with me. She went to visit them after talking to my mother for a few days, meanwhile I’ve lived there for 17 years and somehow she thought she knew better than me. Even when I told her some details about my childhood she still tried to push supervised visits, saying my father was ill and my son had a right to meet his grandparents, which I don't agree with at all. The thought of children being around these people makes me sick, but she seems reluctant to agree to officially limit their visitation rights. I'd need her agreement, however, unless I want a court case. I also tried to explain why this felt like a betrayal, because this is not just about putting my son in danger, its also about her going behind my back for months. What else would she be capable of? Then she told my son to keep the visits a secret which is exactly what abusers say too. She did apologize, saying she made an honest mistake and feels like I'm blowing this out of proportion and that her parents think so too. Besides, our son is fine and I shouldnt have raised my voice at her mother and should be more grateful for what her parents have done for me and us over the years (which I am, I owe them, sure, but that doesn't mean they can just overrule my parenting decisions or get so involved). I feel like neither her nor her parents trust me or take me seriously and its so frustrating when the mother of your son is pretty much actively working against you. I don't think she can even grasped how terrified I was when I talked to my son about their visits. Again, I know its my fault for not telling her everything but I never thought she would do something like that. My past never really affected me much anyway, I never felt like there was a reason for her to know all the details. Honestly, I don't know if anything is resolved. I know why she made the choices she made but I don't feel like she understands why I was and still am upset. She left after bringing up her mother because I got angry and I know I shouldn’t have but I reveal something so big and just still don’t get taken seriously. I want us to work and she agreed that it'd take a lot of work to get back to before all of this which I’m not sure is even possible. I apparently deeply upset her and scared our son (true, I never wanted us to fight in front of him like that either) and I angered her family. I think for me emotionally all feelings for her vanished the moment I found out so that’s kind of where I'm at now. I wish we could make it work for his sake but I don’t want him to grow up with dysfunctional parents or with his parents fighting every day so if this doesn’t work out ill need to get a lawyer. I'm willing to put in the work needed for us to stay together but I’ve been doing a lot of thinking. We were so young when we started dating and had our son and I'm not sure I ever thought about us staying together forever. I only stayed because I was living with them and then I stayed because I didn't want to be a shitty teen dad, abandoning my son and the girl I loved (because I really did love her I think, also I am partially responsible for her being pregnant in the first place) before he was even born. As for my son I have talked a lot to him these past few days. I had taught him about touch and what's okay and what isn't so I just hope its true that nothing happened. He has also, apparently, not seen anything inappropriate. Our fight got to him though and he knows I was sad and knows his mom is too and I hope him and I talked it out enough and that my gf gets to talk about this with him too. We might just sit him down or something, I'll need to talk to her about that. TL;DR my gf went over to my parents behind my back since September after my mother reached out to her, arguing my father was ill. She gradually became more comfortable with leaving my son alone with them. As for why she didn’t tell me, she said because she knew id say no but she wanted to see what my parents were like. I guess she figured they weren’t that bad after all, but she had backed herself into a corner that first time her and my son visited them in secret. It seems like she thought all was well and she had good intentions, repairing that relationship at least somewhat. She thinks my son has the right to get to know his grandparents and she’s reluctant to agree to take away their visitation rights. I don’t think her and I are or will ever be on the same page about this, I don’t feel like she understands what could have happened, what these forms of abuse look like or how they work. Her parents, this far, are also agreeing with her (but I haven’t talked to them yet) She did apologize, but said I’m overreacting and we agreed to work on all of this but I'm not sure that will be of any use. At least our son seems fine. Edit: I feel the need to clarify a few things, also I see a bunch of people fighting in the comments and I didn't word things as clearly as I should have in the post. I went no contact with my parents when I moved out for good. When my gf was pregnant we talked about my parents and I told her I did not want to tell them they were going to be grandparents, and I did not want them to ever see our child. She agreed and that was it. Her and I have talked about my childhood prior to my first post, she knows enough about my living conditions to know it was unsafe for any child, she knows my father is a violent alcoholic and she knows about a lot of the crazy shit my mother pulled over the years. She knows my sister has a ptsd diagnosis and she knows my father touched her. That is everything she knew, and I honestly think that should have been enough. Her parents also know about most of this. Yes, I raised my voice at her and her mom when I found out she had been taking him there and I should definitely not have done that. It's been really really hard to stay calm when talking about my parents especially with her refusing to listen to me. Our conversation on Thursday was very emotional as well, but I ultimately just shut down after I told her that my father has also abused me and yet she still said "I don’t see why we cant do supervised visits" and I don't even have an argument because logically he cant do anything with someone watching but it still feels like I'd be trafficking my son even if he doesn’t touch him at all and I cant even explain why I feel that way. People in the comments say its just an emotional response which is true and maybe its illogical but I truly don't see how getting to know his grandparents would be beneficial to him anyway. The reason I hadn't told her the details before is because I was fine being intimate, I managed at work, it's not like I want to kill myself every day because my parents were shitty or something. It didn't need to be brought up and then having to talk about it is just painful and theres a lot shame and just things my parents I guess brainwashed me to feel. It felt even more impossible after how dismissive she was. Things have calmed down between us now, maybe its sinking in for her now even though she still argues that nothing happened and ultimately everything was fine but it feels like thats just her inability to accept she’s made a mistake (repeatedly). She said she really thought they were okay because they seemed normal (clean house and all, their dog is not a ball of matted hair like our old one, everything being the opposite of how I described it). I don't think shed bring him there behind my back again but I obviously can't say for certain. We have not talked about this any more, maybe we need that right now so our son doesn’t realize how bad it is between us currently though I'm worried he knows anyway. I think we will separate though, I don't see us as future partners anymore. Her teaching him to lie to me (and her parents apparently told her that isn't a big deal) really scares me. I'm scared they will paint me as abusive or something because I really don't have much going for me when it comes to custody. Shes the one with a functional support system, with people helping her look after our child and her parents have the money for a good lawyer and can risk a lenghty legal battle. All of this however are things I need to talk to a lawyer about as soon as I find one. I'm not feeling anything for her anymore, not even anger. I know we can't stay together, I don't want us to end up like my parents, I don’t want my son exposed to that so I'm going to have to discuss separating with a lawyer and then decide from there. I think the best I can hope for is that well separate without much fighting and that we can coparent effectively which is also why I don't want to stir up any more arguments. I'll definitely take legal steps against my parents seeing him though as well as taking him to a doctor. ----NEW UPDATES---- Editor's note: the next two updates are over several months old, and they have not been posted onto the sub here Update #2: March 29, 2025 (three weeks later from the previous update) My gf and I broke up Hello guys, I’ve had people reach out in dms and I’m sorry I didn’t get back to you or answer any comments I was just really overwhelmed by the attention my post garnered. Someone told me my post was shared to another sub which I think lead to an increase in people commenting and reaching out so I kinda just gave up. I don’t know how many people will see this post or if it will be shared I think I would prefer if this got a little less traction lol. Thanks for offering help and advice, I think I’ve read most of the comments and a lot of this was really good advice so I guess it was good so many people saw it. I finally have some time to make another update: My son is alright. Thank god. I’ve been calling doctors and therapists until one of them (even though booked) offered to do an assessment. She even stayed longer in her office for us. She also, thankfully, gave me a bunch of resources and organizations I can reach out to. According to her he doesn't display any warning signs of abuse, the physician who works with court cases said so too. I am incredibly relieved, I guess we can't be sure and the past weeks seem to have taken a toll on him but at least the rest is alright. She’s been recommending another therapist who lives a bit farther away, in case he has issues adjusting to us splitting up. So yeah, my gf is now my ex. I don’t even want to go into detail about all the shit that’s happened in the past weeks. Honestly this whole thing was just the last straw. Maybe its a change of perspective after her betrayal but I put up with her for way too long. As for how I am doing, I honestly don’t know. I'm incredibly overwhelmed still and its starting to turn into physical symptoms of stress. This is of course not good for my son because he can sense I’m sad and tired. I have hardly any motivation anymore and I guess I’m really lucky that I have another person to care for, I don’t know what I would be doing otherwise. He's pretty much the only thing keeping me together at this point. I’m worried he somehow feels responsible for me and the whole situation. He also frequently asks if everything is okay, but we've been reading books about parents splitting up and about mental health stuff and it seems to help him be less anxious. I also got a lawyer. We have a custody plan, sort of. She’s currently back to living with her parents so we each have some space. Weve been to a mediator actually and have talked about my childhood and everything that’s transpired these past weeks. Having someone else there to back me up and use scientific terms has apparently given me some credibility. Part of our custody agreement is that he won’t be around my parents at all, which she actually agreed to right away. She still doesn’t admit that she really fucked up but it's whatever at this point. I've made it really clear that I will take this to court if she ever goes behind my back again and I’m going to go the official route as well to take away my parents’ rights (currently looking into that more). If they want to take this to court I’m going to go public about their abuse and I’m going to fight them, even with no proof. There's also the option of facilities where staff can monitor visits, if my parents manage to get visitation ill demand we do that. Thankfully it looks like my gf, and I have a somewhat peaceful separation. Things have been really difficult with her in private after I broke up but its calmed down now. We both want to remain on friendly terms (or at least not hostile) for our son and that won’t work if we each fight for full custody. This also means I will not try getting full custody. I am already overwhelmed enough, and I’m scared it will just get worse the older my son gets and the closer he gets to the age I was when my father’s abuse got bad. My lawyer thinks this is the best route too but I will be collecting evidence against her just in case something happens. I might be paranoid, but I think its normal after what’s happened. People have been very kind, not just here on reddit but also those around me. I made my last update feeling very hopeless, worried about my son and having to take leave to deal with everything then there’s also been my financial situation. My lawyer is doing this pro bono, and my bosses have offered their support when I informed them I needed leave to deal with a family emergency. I am going to figure out a work schedule but doubt I’ll be still able to work at my job full time in the future. Things will change once he goes to school, but I had just been given more responsibility at work (and was getting paid more) so I was planning on paying back my gfs parents but I’ll have to put that off for now. I will also probably have to move, which is another stressful thing currently. Things aren't looking great to be honest, but I at least don’t feel as lost anymore. I also will be doing therapy. I knew I should but kind of procrastinated on finding someone for years. I think this might look good on paper but above all I think I need it, especially with all the things going on. I hope therapy is going to help with the feeling of doom lol and there's a bunch of stuff I should be addressing especially because I’m kind of figuring out how damaging this relationship with my ex has been. So yeah that’s it. I really think this is the best way to deal with this whole thing and the best outcome. TL;DR My gf and I broke up, went to a mediator which helped somewhat but we have a custody agreement in place and are figuring out a schedule. Things have been sorta peaceful and I think the custody stuff is working out. She also officially agreed not to take my son to my parents anymore (it’s part of our agreement). I will however collect evidence against her and my parents if I ever need to go to court and I’m looking into any way I can limit their rights. My son is stressed but okay, he has apparently not been abused according to two experts. I am more stressed and less okay but I'm getting lots of support and will start therapy. I don’t know how things will go with my job and I’ll probably have to move (gf is living with her parents) but I know that all this will be settled at some point and I just have to get through this. Relevant Comments Commenter 1: Did her parents know about the abuse? And I’m glad you got things worked out. OOP: they knew I would get beaten but they never knew how bad. They also know my sister quit working due to her mental health, but I didn’t tell them about the sexual abuse. Commenter 2: I'm sorry but also happy for you. I hope you excel. If not for yourself then for your son! We are all routing for you! Also what has her parents reactions been (only if your comfortable sharing of course)? OOP: Yeah it’s just kind of unfortunate all this has happened, I’m still trying to get used to the whole situation, but I hope it can only go up from here. Her dad seemed alright with us breaking up actually, he came by to help her pack some stuff and we had a casual conversation. His dad was a soldier and while we haven't talked about it much I think he knows what it’s like to grow up with a father similar to mine. Her mom has been kinda treating me like I don't exist. She's come by to pick up my son a few times and has been acting very cold, she didn't even really greet me or talk at all even after I apologized for last time. I haven't actually talked to them about the sexual abuse, and I don't know if my ex has but I’m not sure I ever will. Telling her and a bunch of doctors and lawyers was enough for now. I think I might, I don't know yet. I’ll have to if they start meddling. had to edit bc I’m still not used to calling her my ex Update #3: January 5, 2026 (over 9.5 months later) Update Jan 2026 I want to thank every single one of you for reaching out and sharing your own stories. I’m sorry for not being active and ignoring pretty much every dm I got. It means a lot to me, it’s just a lot to reply to everyone. I’ve been meaning to make a post on our current situation, I even had a couple of drafts, but they never seemed good enough. But considering that I got about 20 dms, I think it’s time to make an update: My father was hospitalized in September and died beginning of October. It’s been hard, I had a lot of conflicting feelings especially because I didn’t go to the hospital or his funeral. My sister didn’t attend either. Our mother reached out but she hasn’t since, hasn’t even made any Christmas posts. I don’t know what she’s doing or where she is, I think she’s currently at her mothers who has dementia and can’t be left unsupervised. After his death things got tough. I had issues dealing with everything. My ex and I had been trying to rekindle but I quickly figured out it wouldn’t work. I’m trying to heal from everything that happened at home and during all of this I started to see what had been going on in our relationship. We were both young and her and her family were my easiest way out. I ended up in a situation similar to the one I had just gotten out of, it took me a while to accept that. The past few months she’s been doing things I don’t agree with, and she’s been going against pretty much every single one of the agreements we’ve made regarding custody. Her new bf’s gonna be doing a cross country move and it looks like she’s coming with. I’m glad to be honest. It seems like she just wants to move past what’s happened between us, including our son, and I’m currently in the process of getting full custody. They’ll move in two months, she agreed to give up legal and physical custody and pay child support. Although this hurts and I know this is going to hurt my son, I think this is the best case scenario. She’s bad at choosing partners and can’t provide a safe environment for children and I’m tired of fighting. I wish I had a less infuriating update, but this is just how things are. My son is doing well, all things considered. My sister and I moved to a bigger place, he’s made friends with kids from the neighborhood and is doing well in therapy. He is angry a lot but were working through that, he’s also started to get extremely picky when it comes to food. But that’s apparently fairly normal. He also wants a dog, which is the only Christmas present I couldn't get him. But I hope he has everything he needs and I’m trying to establish an open and honest relationship where he feels safe. He hasn’t discussed anything alarming, hasn't mentioned anything in therapy or to my sister either. I am keeping an eye on him, and I just hope that we manage to give him everything he needs and that once he’s older, he knows how to communicate if he ever needs anything else. The last time he saw his mom was on Christmas, but we are fostering a somewhat good relationship with her parents. I am doing alright I guess, I’m trying to work through everything but because of everything else going on I don’t really have enough space to allow myself to feel anything besides stress. I have a new job now with flexible hours and my sister and I are pulling through until he can eventually go to pre-school. Her and I have always been pretty close and I’m grateful that we’ve gotten a lot closer. Her mental health has also improved and even though its been a lot on both of us I think having a child around has really helped her improve. I am so incredibly grateful that I have so many supportive people in my life, including her and our neighbors, our new landlady and all the strangers I got to meet online and irl. I’ve experienced a lot of kindness over the past few months and especially hearing that people are proud of me for standing up for my son and for how I’m managing has helped and stuck with me. I had initially left out the part about me and my ex briefly getting back together. But I decided to be honest on here. I think because of therapy, because I’ve been looking into how men deal with abuse and how little society pays attention to victims who aren’t what they deem "successful". I feel like somehow I have a chance to do something, even if this will get lost among everything else happening online. I guess that’s it, I wish everyone who has reached out and shared their own struggles, that they will continue to heal. I hope all of you have a pleasant 2026 Editor's note: OOP did not leave any comments here in this latest update DO NOT COMMENT IN LINKED POSTS OR MESSAGE OOPs – BoRU Rule #7 THIS IS A REPOST SUB - I AM NOT OOP submitted by /u/Choice_Evidence1983 to r/BestofRedditorUpdates [link] [comments]

How Trig was done before scientific calculators were a thing
This book was used by my grandpa first with a slide rule, then with a 4 banger calculator to do math for designing radios he built himself from scratch (made his own inductors, metal boxes, and obtained every part via scrap) Anyway most modern calculators that are capable of doing trig, and logarithms are still using this book in the form of a lookup table stored in the calculators Rom Back in the day you'd substitute sin(#) for the closest matching number found in this book (it's listed in degrees and minutes of degrees) The book was published in 1938 for Ontario schools so students could do trig, logs and compounding interest. My grandpa likly used this and specialized slide rules till the mid to late 80s. (LC tank circuit/inductor winding slide rule, ohms law slide rule, parallel/series resistor slide rule, and a generic math slide rule) submitted by /u/Outrageous-Drink3869 to r/mathematics [link] [comments]

January 1972 brought us the HP-35, the worlds first hand-held scientific calculator. It cost about $400 and everyone was talking about it. Our teacher brought a few into our class and we got into groups and learned how to use all of the functions.

TIL for most engineering, scientific, and everyday computer calculations, only about 15 to 17 decimal places of Pi are used, because this matches the precision of double-precision floating-point numbers, the standard format for numerical calculations in modern processors

A Tic-Tac has been spotted on Mars by the NASA Mars Curiosity Rover Mast Cam on Sol 2692 3 March 2020!
Most zoomed of the tic tac shaped object - No AI More pictures at the bottom of the post! ----------------------------------------------------------------------------------------------------- Update 3 - @ Ross Coulthart, u/BrushPass, in regard to the shininess of the object, the photo you displayed in your Realty Check Q&A is not enhanced or sharpened with AI. Since you @'d me/this post, I suspect you know that and mean AI/algo's at all, in which case, perhaps the color was done with an algo? See below on the Mastcam color. Also, there is a AI upscaled photo at the bottom for comparison. Also, love your book, love Need To Know and Reality Check, and you're inspiring me to try to get my own research/writing out in the public, hoping to share it this summer after sapco, SPR/DOPSR, PA, editorial, and peer review, so thank you! The Curiosity rover's Mast Camera (Mastcam) is actually made up of two separate cameras: Mastcam-34 (left eye): 34 mm focal length Mastcam-100 (right eye): 100 mm focal length (more zoomed in) Both are true color cameras, meaning they have Bayer pattern filters on their CCD sensors—just like a consumer digital camera—so they can directly capture color images without any need for artificial coloring or algorithmic guessing. Raw Image Transmission: Filtered Images: Sometimes the Mastcam uses narrow-band filters for scientific purposes (e.g., geology or atmospheric studies). These images are usually black and white, since they're taken with specific wavelengths of light—like infrared or UV—that don't correspond directly to visible color. Post-Processing: Color images may be created by stacking multiple filtered images or by processing the Bayer pattern data onboard or back on Earth. NASA sometimes also adjusts white balance to simulate what the human eye would see under Earth lighting conditions (called "white-balanced" or "true color" versions). ----------------------------------------------------------------------------------------------------- Update 2 - A new image has surfaced that shows the tic tac shaped object missing from another picture taken at a different time of the same area! Looking for the source raw picture now if anyone can assist. A new image has surfaced that shows the tic tac shaped object missing from another picture taken at a different time of the same area! Link to 2nd i raw mage at NASAs site in the OP comment post. ------------------------------------------------------------------------------------------------------- UPDATE 1 - We now have gotten some help with the scale issue! u/tweakingforjesus did some solid work calculating size/scale estimates! Here's the tldr of his work: the length of the object would be about 9mm.. See below for his work! (also see new panorama for scale visualization) Would still love an explanation of what this could be. Still seems significant to me regardless of size, even if not for ufology, for science, or both!? Things still unexplained and significant in confluence is the shape, apparent material and reflectiveness, as well as it casting a shadow appearing to be in the air. To say its Just a round rock, is seemingly simplified and without curiosity (no pun intended) Avi Loebs spherules are sub millimeter - a few millimeters and still hold significance to perhaps both ufology and science. Appreciate everyone who helped with the photos, and further research for explanations. I'll continue to update this if info of value comes up! ------------------------------------------------------------------------------------------------------- A Tic-Tac has been spotted on Mars by the NASA Mars Curiosity Rover Mast Cam on Sol 2692 3 March 2020! Check out how its casting a shadow on the surface! Time: Sol 2692 3 March 2020 (2020-03-03 02:32:29 UTC ) Location: Mars Longitude: 137.38077432° Latitude: -4.73673265° Shout out to Azuul for finding this! A bunch of people tried posting it but all their posts got deleted. He also said "Also it seems like NASA has removed the MASTCAM/MAHLI from Sol 2692. It's not showing up on the site. But the screenshots and composite I found was made previous to this so it still has color. But all the pictures on NASA are in black and white." I will post links in my comment post so this doesnt get deleted again. Thanks to MTMitchell for saving the Panorama and doing the zoom pics. Below is a panorama with subsequent zooms and the raw black and white photo that is still up on NASA's site. I looked up SOL 2692, its about at this location: Longitude: 137.38077432° Latitude: -4.73673265° Camera specs will be in my comment post. *Note, many people will comment on the shadow, as it appears to look a little deceiving. MrTotonka made this photo about the stitches in the panorama to explain it. thank you! * ~*~ * We now have gotten some help with the scale issue! @ u/tweakingforjesus did some solid work calculating size/scale estimates! Here's his work: *~ * ~* Sure. The metadata file is located here for the first mastcam right image: *Link removed so this doesnt get auto- deleted again* see OP comment post. The section labeled "Derived Data Elements" contains the focus distance. MSL:MINIMUM_FOCUS_DISTANCE = 3.8 MSL:BEST_FOCUS_DISTANCE = 4.273 MSL:MAXIMUM_FOCUS_DISTANCE = 4.8 Presumably the focus was automatically determined, which provides a rough distance to the center-ish of the image. It also contains the calculated azimuth and elevation angle relative to north and down of the mastcam camera at the time the image was taken: FIXED_INSTRUMENT_AZIMUTH = 127.6351 FIXED_INSTRUMENT_ELEVATION = 2.3523 The camera was pointed southeast and slightly upward. In "Instrument State Results" it shows that the exposure was 1/60 of a second. Also the horizontal FOV is 5.6 degrees (100mm is a telephoto lens): HORIZONTAL_FOV = 5.6012 VERTICAL_FOV = 4.9947 DETECTOR_FIRST_LINE = 1 DETECTOR_LINES = 1200 MSL:DETECTOR_SAMPLES = 1648 DETECTOR_TO_IMAGE_ROTATION = 0.0 EXPOSURE_DURATION = 17.4 Just find the image filename to locate the matching LBL file for any of the images. To calculate the size of the object, just use simple trigonometry: Width of image at focus plane: 4.2 m * sin(5.6 deg) = 0.410 m Size of pixel at focus plane: 0.410 m / 1648 pixels = 0.00025 m Size of object at focus plane: 30 pixels wide * 0.00025 m = 0.0075 m or 7.5 mm If the object is at 6 m distance, it is 10.7 mm. If the object is at 3 m distance, it is 5.3 mm. Here is a new panorama for visual Reference. I'll update my OP comment post with the link to the panorama of this. new panorama for scale visualization https://preview.redd.it/sirn69h6idoe1.jpg?width=886&format=pjpg&auto=webp&s=be81813d659d510fe5867d9dfbba318863ccde49 https://preview.redd.it/tpuhui42fdoe1.png?width=1095&format=png&auto=webp&s=fd078628feb1e0185e3cb2768d8e07365335ace2 This picture is stitched but Not enhanced with AI Not enhanced with AI Not enhanced with AI NOT enhanced with AI NOT enhanced with AI Most zoomed, not enhanced with AI Most zoomed, and sharpened or AI upscaled. not sure, got this from Azuul https://preview.redd.it/sunyi828fdoe1.png?width=1253&format=png&auto=webp&s=c9f43d068a0abad84f00b950d5129898f86637b5 https://preview.redd.it/xdzbhpr8fdoe1.png?width=377&format=png&auto=webp&s=8923a5a4112c60b8f7e6cb736a927cf9945fb046 submitted by /u/tcom2222 to r/UFOs [link] [comments]
