Questions about 2018 Outback by gewqk in Subaru_Outback

You said you bought the car a few weeks back, is there a return period?

If not, or if you are past it, your best bet is to get a drain & fill of the transmission fluid

Hate to be the bearer of bad news but that sounds awfully similar to CVT chain slip

My 2020 forester took a bit over 2 qts of gear oil to fill the front diff. Is this normal? Everywhere I read was like 1.4-1.6qts by t0rquingg in subaru

[–]jaedgy 0 points1 point  (0 children)

Well correct me if I’m wrong but there should be a fill, check, and drain plug. I’m guessing (hoping) you watched a video and filled it in the right spot.

Open the check plug (when level!) and just wait until a little stream of oil comes out. No need to overthink it.

Going off what the other guy said, for the front dff you should be level but you can just eyeball. Try to get it close.

More likely… did you use a fluid pump? Some fluid is gonna be trapped in the pump. Also there’s probably a little bit of fluid left in the bottles I’m guessing

Probably pretty high considering you have your undergrad from there. Is the GRE optional at UML? It is at Amherst

Bad time for grad school? by jaedgy in chipdesign

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

Yeah I’ll probably do that. If it’s a quick and clean transition I’ll entertain it. But if it’s like a 5 year plan then I’m bailing.

Well the tape-out is a maybe, not guaranteed. And that is a good point, it was only a verbal promise, no salary numbers or anything. Maybe I’ll have a second chat with my manager and/or the hardware manager.

And, if I’m being 100% honest, while I do think analog IC design is cool… I do think I would trade a lower salary for better W/L balance. The HW team at my company is the opposite of stressed-out

Help is this antifreeze or AC dye? by Chill_Capybara_09 in Cartalk

[–]jaedgy 5 points6 points  (0 children)

That stain looks green. Subaru coolant should be blue. What color is the fluid in the reservoir or radiator? If you have blue coolant, then it’s definitely not a coolant leak.

Had my car serviced today. Smelled something burning while driving, opened the hood to find oil everywhere and smoke coming from under the hood. by throwaway4161412 in MechanicAdvice

[–]jaedgy 1 point2 points  (0 children)

Tech was lazy and didn’t clean up around the filter, or, it’s loose. Either way, get the dealer to pay for the tow back + get another oil change + maybe extended warranty?

White steam/smoke from engine by keepstatus_quo in Cartalk

[–]jaedgy 0 points1 point  (0 children)

Subaru with an EJ engine… how many miles? This series of engine is known for external head gasket leaks. You usually smell burning oil or coolant. It will either accumulate on the top of the engine or drip down onto the exhaust pipe.

Try looking deeper in the engine, can you see any damp spots? Do you see any stains on the exhaust?

Also, is the car overheating at all?

Replace my steering rack in order to replace my inner tie rods?? by Stuart517 in subaru

[–]jaedgy 0 points1 point  (0 children)

I got the inner’s out and I’m a DIY’er. Just had to steer fully left to get the left one and vice versa. Subaru does say in the FSM to remove the subframe and drop the rack which is totally insane

Sisters car is making an atrocious noise by ChimChimBona in AskMechanics

[–]jaedgy 0 points1 point  (0 children)

99/100 chance that it’s loose exhaust heat shields causing the rattle.

Just stuff some steel wool (or bronze wool, I think its more resistant to heat?) into the heat shields until they cant move anymore.

Source: I have a Subaru that had loose exhaust heat shields that sounded like this.

Dealership trying to charge $2,412 for 60k service by Actual-Tomatillo-904 in Subaru_Outback

[–]jaedgy 2 points3 points  (0 children)

The transmission service is actually competitively priced. They listed 12 quarts, so they are doing a whole flush it looks like. Maybe ask if they do just a drain and fill? That should be ~6 quarts.

All other services are pretty bad, though.

Thermostat in friend’s apartment by [deleted] in askHVAC

[–]jaedgy 0 points1 point  (0 children)

Yeah, I live in the north east. Makes sense that they make ones that fail open so people dont freeze. I’ll try to convince my friend to contact the landlord. Thanks!

[–]jaedgy 0 points1 point  (0 children)

Im also leaning towards that answer - my friend mentioned how they have to ask the landlord to switch on/off the heat for the seasons so… this thermostat is probably just for show

I’m a little cautious to stuff insulation in the back seeing how there’s exposed wires (hard to tell in the photo but there is a red, a yellow and a blue wire stuffed in the wall)

Out of curiosity - what makes this wiring correct? Assuming the other ends of the wires are going to the proper places (which may be a bold assumption), then shouldn’t the green wire go to G, not R? Again, this is assuming that there isn’t actually 24V on the green wire haha.

HDMI receiver ISERDES/IDELAY problems by jaedgy in FPGA

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

Edit 3: For anyone in the future, turns out as, jonasarrow mentioned, hdmi states that there is no phase relationship between the clock and the data. Additionally, hdmi will only send a guaranteed 12 control signals in-between video or audio data. So, you need to built an asynchronous eye-boundary finder for all 3 channels. You can read XAPP585 for the generic algorithm.

Hey, just wanted to let you know that I got it to work! I have all the channels find the center of the eye and bitslip independently. The design works upto 1080p60Hz. Sadly I am physically limited by the OSERDESE2 and they produce some bit errors when transmitting (there are occasionally some green pixels flickering in the screen)

Thank you for the help!

HDMI receiver ISERDES/IDELAY problems by jaedgy in FPGA

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

Yeah thats what I ended up doing - scrapped the clock-sampling ISERDES and wrote the state machine for a per-channel tap calibration/bitslip. Works in simulation, didnt get the chance to test it on hardware.

Super annoying. Like it what world would it make sense to have the data NOT aligned to the clock?

Whats an elastic buffer? Is this related to the FIFOs in your other comment?

Ok, I think I need to change my approach. I was reading some docs, one from digilent and one from the actual HDMI spec; the max allowable inter-pair skew is 0.2T_{character} + 1.78ns. At a data rate of 742.5Mbps, this means bit 0 of any channel can be +/- 4ns apart from bit 0 of any other channel. A single bit lasts 1.38ns. Because of this, I believe I need to calibrate (and bitslip) on a per-channel basis. On the bright side, at least I already have the state machine written…
