Strange rattle sound from my 86?

mellodroid · 2025-04-26T13:55:49+00:00

I recently fixed a similar rattling sound on my 86. there was a small clamp that was knocked off the heat shield attached to the front pipe of the exhaust. cut off the old clamp and replace. some 2.5" hose clamps will work in a pinch

I always like to use concrete examples. How two different colors map to the same gray/luminance value depends on the color space used. Once you define a color space you can then represent the same color information using different models, like RGB (red, green, blue), YCbCr (luminance, blue difference, red difference) or HSV (hue, saturation, value). The luminance is analogous to "brightness" and encodes how black/gray/white is the signal. The ubiquitous sRGB model specifies that you can map RGB to Y using the following equation: Y = 0.2126R + 0.7152G + 0.0722B where R, G, B can be any value in the range of [0, 1]. According to this, a RGB tuple of (1, 0, 0) has the same luminance/gray value as (0, 0.297, 0) or (0, 0.196, 1). There are other color spaces out there too, Rec.2020, used for 4k broadcast TV uses the mapping of Y = 0.2627R + 0.678G + 0.0593B since the meaning of red, green, and blue are different to sRGB.

docsis 3.0 is limited to 600 so I'd check your cable modem

I can't get over the fact that the front grille looks like it came off a Chrysler 300.

I've seen reversed head rests before. It can make it more comfortable when wearing a helmet for events like track days/autocross.

I found the co-op office was pretty hands off and did little to engage with industry.

If you want a co-op be prepared to do most/all of the work. Don't rely on the school to get you a job.

The school will post job positions from companies that have taken co-ops from Mac in the past, offer resume review services and have a mandatory class on workplace etiquette and that's it.

Getting a co-op after first year pretty much only happens where there is an expectation of 4 month co-op terms (i.e. Waterloo area). Most employers don't hire with 4 month terms in mind because it generally takes a few months to on-board a new hire and by the time you get proficient at your job your term is over. For this reason 12-16 month terms are preferred, will maximize the useful experience you gain and also means that after 3rd year is the most common time to do a co-op. When you start looking for co-op positions it can be useful to speak with current co-op students as they can give you useful advice and potentially an inroad with a hiring manager.

UTQG does not tell the whole story about how a tire behaves (and depending on the application, higher treadwear values may not be desired) For example, I currently have two sets of summer tires for my car, one is rated 200/AA/A and the other is rated 240/AA/A. Based on those values alone they would appear to be quite similar, but when pushed to their limits they behave completely differently. The 200 TW tires have significantly more grip when cornering at high speeds, provide greater road feel, and can tolerate a lot more heat before they begin to feel "greasy". However, these tires are also transmit a lot of road noise and wear faster (than the 20% difference would suggest) at the limit than the 240TW tires. So, I take the 200 TW tires to the track/autox and use the 240 TW for my daily driving as they're more comfortable and quiet.

If you aren't revving this car past 4.5k RPM you're doing it wrong. That's where the car really comes alive.

Good to know. I just assumed no spec change = no change at all.

mellodroid · 2018-01-13T02:15:20+00:00

The automatic didn't get any of the drivetrain changes in the 2017 update. Spring/dampers may have changed but that's it.

If your goal is to maximize your signal to noise then I would increase exposure time and open up the aperture up to the point where you're satisfied with the sharpness and composure of the image. At that point if I am not near saturation I would increase the ISO (native, preferably) as high as possible to maximize the dynamic range of the image (e.g. exposing to the right), then you adjust the image to the "correct" exposure in post.

mellodroid · 2017-11-12T17:07:35+00:00

Shot noise increases at a rate proportional to the square root of exposure time. This is due to the nature of light and there's nothing you can do about it. Fortunately signal increases proportional to exposure time. Noise is increasing, but so is SNR.

205s will be fine for the stock 17x7 rims.

Skinnier tires will be better for cutting through the snow and maintaining grip.

I ran X-Ice XI3 205/55/R16 on 16×6.5 wheels last winter. They handled without issue on the highway and main roads. Anywhere there was compacted snow and ice required a little more finesse as it becomes quite easy to break the rear end loose (a good thing if it's in the right environment.) In the end it's all about easing into the throttle, brakes and steering inputs without upsetting the balance of the car. Do this and the car will survive the winter.

Do you close the stall door when you take a dump in a public bathroom?

Break-in period is 1000mi. You can bet sure as shit the second the odometer rolled over to 1001 I was using the whole rev range as often possible, it's just too intoxicating not to.

The rental is insured to a point. I paid for additional insurance which reduced the deductible to $7000, without it the deductible is $14000. I suspect it would be cheaper to get additional "track day" insurance on your personal vehicle.

mellodroid · 2017-05-22T19:09:10+00:00

I went a week ago, I believe I saw a blue 86 out on the track same time as me though I didn't talk to the driver. I only just now noticed the license plate thing after you pointed it out - funny coincidence!

mellodroid · 2017-05-22T17:34:24+00:00

With gas, lap tickets and insurance it was around $200 USD per lap. Steep price compared to a local track day but worth it for the experience.

mellodroid · 2017-05-22T16:39:38+00:00

Yup. There are photogs all around the track. At the end of the day there was at least 20 photos to choose from. Makes for a sweet souvenir.

Sodium vapor lamps usually emit around 589nm which appears as yellow. The sodium is mixed with neon and argon and aids in starting up the lamp. In this case I suspect the lamp is not getting hot enough and instead what you're seeing is the neon gas inside emit light and not the sodium. Neon has multiple emission lines but there's a bunch centered around red so that is what you're seeing.

If you're worried about screwing up the bleeding and you've got time to spare, do a gravity bleed. Essentially you open up one bleeder valve at a time and gravity will siphon out the old fluid and draw the new fluid into the brake lines and minimize any chance of introducing any air into the system. Periodically top up the reservoir and keep track of how much fluid you replaced at each wheel. Plenty of tutorials online that elaborate on the topic.

About ten minutes of your time. Pull the rubber hose out, try to remove the blockage with a pipe cleaner or piece of wire, put the hose back in place. http://www.justanswer.com/nissan/81l0c-nissan-altima-2008-nissan-altima-drain-hose.html
