  1. Late response, but nice shots. I'm a photography noob myself, so you can take this anyway you want, but I couldn't help cropping some of these. I tend to obsess a little about the margins and whether what's there really adds anything to the photo. When in doubt, I cut it out. Having a line terminate in the corner of the picture never hurts either. Not trying to be a dick, it's just trying to be helpful.

    Also, I have an NEX to Konica adapter that I ordered by accident. If you want to play around with some vintage lenses, you can have it.

    There is still that venturi/return line that is responsible for transferring fuel from one side to the other.

    Not really sure what's being referenced here, but I would agree that keeping the stock tanks makes sense regardless of any changes that are needed in the delivery system. I put a cell in because the factory tanks physically didn't fit anymore.

    I modified/welded a tank on a motorcycle once... and then JB welded it when it weaped fuel through the welds, and then re-welded and re-painted, and it still leaked... Didn't want to go down that road again, but the fuel cell isn't ideal either. Mine's not connected to the fuel filler outside the car and there is air circulating around in the trunk, which settles in the crevices around the cap, so I'm pretty sure I'm dropping dust/grit into the fuel cell every time I open it...

    Objectively they are most certainly better, but I know what you mean.

    I could spend a lot of time riffing on this sentiment...

    We've lost our way. We've traded in the arts and humanities in favor of STEM and systems analysis. We're caught in the middle between what we feel and what we know, all the while knowing and feeling that what we're doing is not sustainable. Admitting to any of this is to admit that we are wrong and that we've made a mistake. That's too much for most people to deal with, especially since giving up on what we know leaves us in an uncomfortable place of uncertainty. So we continue on, searching for a more logical solution, thinking that somehow going farther down the path that we're on will somehow replace the things we love that we've lost and left behind.

    Thank you for your contribution. Im gonna plan on @B C and I arranging the assignments next Wednesday, so get on the list before hand. That way everyone has 1 month to deliver and take advantage of Black Friday/Cyber Monday as well.

    I understand the need for planning, but my made-up religion prevents me from engaging in winter equinox/baby Jesus b-day merryment until at least Dec. 1st. Please consider this forum post as a statement of intent to join in such merry-making at a time when such activities would be permitted.

    The reason people are frustrated is because what we're doing is working. We're still on the first part of the curve where it's skinny and not increasing very fast. The virus isn't spreading out of control and we still have time to prepare.

    Before the stay-at-home order, the number of cases was doubling about every 3 days. Based on the assumption that our current doubling rate is 16 days and our current number of new cases per day is 250, here's how things will look given the following doubling rates.

    One of the fancy-pants engineers in the room should check my numbers here.

    June 1st

    doubling time    new cases per day
    16 days        841            
    8 days        2828            
    4 days        32000

    ...and by Jun 15th

    doubling time    new cases per day
    16 days        1542
    8 days        9514
    4 days        362,038

    ...and July 1st

    doubling time    new cases per day
    16 days        3084
    8 days        38,055
    4 days        5,792,619


    I would calculate the total number of cases, but that's calculus and I ain't trying to remember how to do that shit right now. Point is exponents will "F" your "S" up. We can't afford to go back to having the number of cases doubling every three days. Even 8 days is starting to look pretty gruesome by the time July rolls around. The point is to keep the curve flat enough so that our healthcare system can handle the surge. That won't be possible if people try to go back to living their normal lives. Currently, I am one of these A-holes causing the problem because I work in a building with 40 other people. So far I haven't figured out how to stop going to work, but still have access to food and shelter... This is a moral dilemma for me, since my job isn't really "essential", we make circuit boards... The best I can do is try to avoid it if possible, and do my best not to spread it if/when I get it.

    We did better than I expected, but....

    Wow, exponents!

    Unpopular opinion: By the time a vaccine is widely available, the virus will already be on the decline because ~50% of the population will have already contracted it.

  6. Hmm, suspenseful. Great post so far.

    No doubt that people have become achingly nostalgic about the 90s given all that's happened in the world since then. From a car-centric point of view, the 90s was when the industry finally started to catch up with the environmental and safety regulations that came into affect 20 years earlier. As an e21-loving curmudgeon, I'd have a hard time accepting any argument that the early 2000s was some golden age. That being said, riding an e46 to me feels better than an e90. The feeling of riding in newer cars feels like riding in a steel egg, lined with thin metal bubble wrap. Safe and protected, but completely isolated from the sensations of driving we remember from the older cars.

  7. Finally getting some motivation to do some things. Nothing BMW related sadly.

    Machined this neat little brass piece for the bridge on my bass to replace the incorrect part that has been there since I bought it like 7 years ago.

    I found an old 1980s CCTV security camera at work that had an interesting looking lens on it. 50mm f1.4 made by Fuji. So, I decided to make an adapter for it. It's a c-mount lens, which has a shorter flange-to-sensor than micro 4/3. They make adapters, but the diameter of this lens is to large to fit, so long story short, it's a macro lens now. Worked out pretty well.

    Neat.

    Never heard that one. Im in a noisy room but it sounds like a slightly more upbeat Ozzy.

    Understandable. Let me digress...

    As usual, I read a lot of sub-text into things where they weren't intended...

    Whether we like it or not, we're all trapped in a game of us-vs-them. It's the natural order of things. I only hope that yall can work to crate a larger us.

    Huge fan of all of Adam Curtis' films:

     

  9. Sounds like a CV carb. Presenting the fueling system with a step-change in manifold pressure makes it's job a lot harder. Most of the sensors that are used to measure what's going on in the engine have some sort of time-constant associated with them, so the computer only knows what happened maybe 20 or 30 milliseconds ago. Meanwhile, it's trying to guess about what the correct parameters are for the next combustion event when the current one hasn't even completed. Slowing down the rate-of-change helps it to guess better, which should result in better combustion.

    There are probably other issues as well; the air that's rushing in to the intake manifold to bring it up to ambient pressure has mass and therefore inertia, so there's likely to be a little bit of reverberation in manifold pressure until everything equalizes.That's the most likely explanation I can come up with for the CV carb. Air could even potentially flow backwards through the carb, which would cause it to get fueled 3 times before it got into the engine...
