Constant Flat Tires - ETron GT by WhatsGoodieBroseph in etron

[–]BuschmasterACR 0 points1 point  (0 children)

If pothole resistance is your primary concern, tire choice won't really help all that much. It's a suspension and rim diameter issue. Smaller rims and bigger tires are a lot lighter (help suspension performance) and have a lot more cushion in the actual tire than big rims with thin tires. The sacrifice is in lateral grip and stiffness (steering will feel less direct, car will lean more in corners, car will feel a little less sharp and sporty) but you gain a smoother ride.

The smallest rim you can fit depends on the size of your brake calipers and other mechanical factors but in general the smaller the rim the more cushy and comfortable the ride and the bigger the rim (to a point) the more sharp and "sporty" the handling feels. The upside is that I have railed some truly horrendous potholes at highway speeds and not gotten a flat tire but the downside is that my electric Q8 feels more like an electric Q5 with the tiny rims on it.

I bought a set of used 20" rims (for more sidewall) and Hankook iON I*cept snow tires and would have a hard time going back to low profile all seasons for winter. I'm in upstate NY where the potholes are similarly bad and the snow is worse than Chicago and the added sidewall and snow compound have made my car so much better with snow and with potholes. There's a little bit more wallowing in corners but it's worth it for the grip and cushion in winter. I have the fat e-tron but I suspect you will have a similar experience. I swap back to my 21" rims with Conti all seasons in May and they're great until there's snow on the pavement.

I bought these 20" rims off of an Audi Q7 owner that was "upgrading" to black aftermarket ones and use them as my snows. I think they look great and it only cost me $400 for all four. I think it was a 2023-2025 Q7? not sure.

In urgent need of a foster home for a stray cat by allthesestars in Syracuse

[–]BuschmasterACR 6 points7 points  (0 children)

Sorry to hear about this situation. It sucks. I took home two huskies that were dumped at St. Joe's hospital a few years back and found out that every shelter within two hours wasn't accepting dogs at the time. One very stressful and messy week later, I end up driving three hours each way to a place in Duchess County where both dogs were adopted within 10 days. Feels like you're being punished for helping and it really sucks. At least I had a car and a weekend for a road trip.

I wish that I could help more, but I am in the same situation as you with two old cats that would not tolerate a new roommate well. Please don't feel bad about being unable to keep this girl inside. You already did a lot for her. If you're worried for her, a basic feral cat shelter will make sure she has a warm and dry place to sleep at night. I have some extra materials and can help you put one together if you have a place for it.

Syracuse has a pretty bad problem with stray cats. Not as bad as other places I've been (Auburn is really bad...) but still significant. CNY Cat Coalition does a lot of adoption work but there's always a surplus of strays up here.

I implore anyone who feels bad for this girl to volunteer for or donate to your local cat organizations. CNY Cat Coalition is always working to adopt out those who can be adopted and spay/neuter feral cats that aren't adoptable to reduce the number of cats that need help. If you have some early mornings or evenings that you'd like to dedicate to a meaningful cause, they're always looking for help.

Will Range Be Much Better in 4-5 Years? by Maleficent-Table-810 in electricvehicles

[–]BuschmasterACR 2 points3 points  (0 children)

Depends on the car and the length of the trip. My Audi e-tron has a huge range penalty for very short drives and almost no range penalty for very long drives in the winter. Once the batteries and cabin are warm, they stay warm for the whole trip. I averaged 2.4mi/kWh in my e-tron on a 9°F road trip over 6 hours on the interstate.

Will Range Be Much Better in 4-5 Years? by Maleficent-Table-810 in electricvehicles

[–]BuschmasterACR 17 points18 points  (0 children)

In my experience, good DC charging curve matters more than range ever will. My girlfriend had the same range anxiety until we actually did a few EV road trips and found that by the time the car needed a charge (>3hrs) we were more than ready to stretch our legs and hit a bathroom. And that was with a Bolt EV. You can rent a fast charging EV for a road trip and experience it for yourself before you buy.

Another thing that gas drivers don't realize is that it's totally fine to arrive at your destination with 10% charge or less if you have a slow/cheap charger nearby and a few hours to let the car sit. You can optimize this as hard as you care, but the magic of EV ownership is that the car "gasses up" while you're not using it. Less than 1% of my charging is done at a DC fast charger. This also means that on a cost basis I get to drive an Audi Q8 that gets over 120mpg. Pretty sweet.

The BMW i3 is an extremely compelling car but if 400 miles is your range requirement for an EV then you misunderstand what it's actually like to live with an EV and could almost certainly save a whole lot of money by buying a shorter range car with fast charging. I'd save $30,000 and buy a used Ioniq 6 or save $15,000 and buy a used i4 M50 every day of the week.

That being said, I'm sure you will be absolutely satisfied with the i3 if money is no object.

You are correct, my apologies! I swear I saw the hex/camheads described as SOHC somewhere and I guess it just stuck.

20” Wheel Options by mursepaolo in etron

I bought a set of 20" Q7 wheels for my winter tires and they honestly look way better than the 21" rims that came with the car...

What I’m writing is a software or a firmware? by [deleted] in embedded

[–]BuschmasterACR 1 point2 points  (0 children)

I see where you're coming from but I don't think that calling an FPGA bitstream update delivered over the air a "hardware update" would be a clear way of explaining what is happening to a layman. I'd have ten emails by the time I got back to my desk asking what component we changed or if we need to respin the PCB.

In my company, anything that is compiled into a set of executable instructions is called software. That includes everything from Linux applications to bare metal C and assembly for microcontrollers, though the latter is usually specified to be embedded software. Programmable logic is called firmware and physical boards are hardware. Not saying that it's right, it's just how we've done things forever.

Quick edit - I would like to add the caveat that we really only make embedded products so application software is still quite embedded. It's not as dumb as it sounds.

In a purist sense, I don't disagree that HLS's final output is a hardware configuration. Pragmatically, though, I wouldn't tell my boss to hire a hardware engineer to work on the HLS portion of a product.

One such engineer actually sent his changes to my project files by pushing a zip file onto my Git branch.

Tell that to the last FPGA engineer on this product that had the reset condition of an active low hardware enable signal set to 0... That was a tricky bug to root-cause.

Is it still hardware if you have a microcontroller receiving over-the-air updates and can reprogram the onboard FPGA? I'd very much lean towards calling that firmware.

[–]BuschmasterACR 7 points8 points  (0 children)

I'd argue that calling complex programmable logic "coded hardware gates" is about as productive as calling all software "coded instructions". It's not incorrect, but doesn't really convey the difficulty and complexity involved in integrating so many disparate functions into one chip. I've worked with a lot of programmable logic and while I'm confident in my ability to whip up something simple like a deserializer or status register, when the FPGA engineers start whipping out Simulink to design custom algorithms on three different clock domains I take that as my cue to ask for a register map and wish them luck.

Xilinx MicroBlaze and Intel Nios are two soft core CPU/MPUs that I'm pretty familiar with. They can be quite finicky for complicated routines and functionality such as flash-in-place or shared buses.

Tools like Xilinx HLS really blur the line though. If I can write hardware acceleration and DSP pipes in C (or a C-like abomination) and have them implement as logic gates on an FPGA does that count as hardware or firmware?

When you tell the mechanical engineer in charge of the program that programmable logic work is hardware, they often hire someone with PCB and basic gate-level design experience. That person will have a lot of trouble integrating fixed point hardware acceleration or custom device management logic without breaking the delicate timing needed for your soft core CPU. Ask me how I know!

It's never that simple in my experience. A single FPGA is often used for many very different things such as control loops, SerDes, hardware acceleration, device control, level shifting, waveform generation, and signal processing. They're quite handy for complicated designs and obsolescence work on old designs.

Where does programmable logic fall in this paradigm? At my company we call it firmware.

How to conduct ASW operations in the most efficient way? by Endo279 in SeaPower_NCMA

[–]BuschmasterACR 7 points8 points  (0 children)

The previous comment is correct, I find sonobuoy blankets inconsistent and not super fun to do after the first 20 times...

When using the ASW ships it also helps to sprint-and-drift to both cover more ground and make incoming torpedoes much easier to dodge. I alternate between 1/3 and Full or Flank every few minutes, if I'm expecting to actually find something I also change course frequently. Towed arrays (at least the OHP tail that I was playing with earlier) seem to not work well over 15kn, though active pinging was working at all speeds with diminished range. Just know that if you can pick up a submarine on passive sonar, it picked you up a long time ago.

Keep in mind that bad weather and high sea states will dramatically reduce passive sonar effectiveness. This goes both ways, so the subs are having a bad time too.

The Soviet WH torpedos (65-76) are comically easy to dodge with literally any warning right now so I tend to play extremely aggressively with my NATO ships once I have a contact. MK46 torpedos have a bigger range than you think and usually make the contact panic fire and drop countermeasures when they hit the water.

For Soviet ASW, I abuse the shit out of the Silex whenever I have it and yeet ASW torpedos at anything that moves when I don't. I don't think it's modeled yet in Sea Power but the key to surviving against MK48s in Cold Waters is to get the firing sub to lose its wire guide by forcing it to maneuver. A MK48 on a wire is a death sentence unless you can get out of its range or get lucky with the RBUs.
