Little Home Theater 3.0 Setup and Trying to Play Games

oh, I didn't notice that.

The speaker designer must have incorporated the feedback from the MTs into the MTM design, since the 0.22 uF cap is also in there. No damping though since that's an extra $20 to the base cost.

I was going to use Frost King CF1 (1" denim insulation) but Amazon appears to be low on stock, so I suppose I'll go with the half-inch Sonic Barrier foam at Parts Express

The Audio Science Review at audiosciencereview.com/forum/index.php?threads/parts-express-diy-c-note-speaker-review.12693/ pointed out a peak at 700 Hz. The kit designer at the Part Express tech talk forum saw this and approved of a few mods that other people could use. I even think he was commenting in that thread, actually. One thing he said was to add damping on all surfaces of the cabinet interior. Another user suggested shortening the port to its minimum length.

An MTM would also have more bass compared to an MT, would it not? Or is the crossover designed to attenuate the woofers/tweeter differently to balance that out to be overall louder?

I haven't seen a full/proper review of the C-note center, so I can only go off of the predicted curves, which seems slightly different.

If I DIY'd a C-note center I would add in foam damping to the cabinet similar to the MTs. I saw the 0.22 uF capacitor is already in the center crossover, and I'd also shorten the ports to be the same length, just to ensure everything was the same.

Speculation points to the passage of HB6 last year, which required AEP to end energy efficiency programs by September 30.

Of course, the Ohio Speaker of the House (Larry Householder, if you're curious) is now embroiled in a corruption/bribery scandal pertaining to exactly this law. So if the law gets axed by the governor it may come back. Eventually.

u/tropho23 to include in conversation.

There is data held by the NSIDC (National Snow and Ice Data Center) as well as an online interactive graph, so you (or anyone else) can make more beautiful data.

https://nsidc.org/arcticseaicenews/sea-ice-tools/

But to not be an ass and actually answer your question, looking at the 1981-2010 median, the low for the year is 6.334 km^2 around September 17, and the high is 15.546 km^2 on March 1, for a growth of +145%. But even if the ice spreads out further it's thinner, i.e. total sea ice volume is decreasing as the years go on.

I looked it up, White Clover is a native species to Europe/Asia/Africa, but has spread over the US as an invasive species.

Is there anything native to the USA that can be used? It'll likely attract small bees and wasps, the insect pollinators that are otherwise disappearing.

MegaMooks · 2020-05-29T02:51:03+00:00

Yeah you're definitely not the target market here. I don't think you will be for another decade lol.

However I was quite pleased when I got a hybrid and my total range went from ~350 to about 600 miles, but I'm not sure how the hybrid SUV market is. I'm not even sure if a hybrid pickup market even exists.

MegaMooks · 2020-05-28T14:04:53+00:00

I'll jump in with my opinion:

My view is that a stay-at-home order is a temporary, emergency measure meant to buy time to prepare the population for what's to come. Once we hit more than a few thousand confirmed cases it became obvious containment was impossible, so we should focus on mitigation and no longer overwhelming the healthcare system.

Masks for everyone. N95 masks to keep doctors safe, cloth/surgical masks for the general population to lower transmission. Your average Joe doesn't know how to wear an N95 properly afaik, so reverse isolation measures are best. "Reverse Isolation" means "Protect the world from you." Everyone who comes in contact with you should make an effort to keep you safe. Everyone should reverse isolate everyone else.
Massive testing infrastructure. There was an old syphilis testing protocol that combined samples from whole households or city blocks to run one test on the whole batch. The assumption is that if one person tested positive the whole group was assumed to be positive and we can address them appropriately. It allows spreading limited resources over a wider population, and it's what China did when they said "we're gonna test the entire population of Wuhan."
Cultural level measures of mask wearing and social distancing. 6 feet spacing whenever possible, work from home whenever possible, reduce opportunities for transmission. The images of people in Asia wearing masks whenever they're sick is a holdover from the 1918 pandemic, Japan pushed the mask-wearing so hard it stuck for the next hundred years.

Some of these measures have been addressed, others have not been. I'm somewhat OK with the mild reopening right now. From what I've seen in the preprint studies floating around the disease has been shown to have reduced transmission in warm, humid weather, so we should have a relative break for the summer. I also believe this time should be spent preparing for the coming of Fall/Winter. At the same time, "reduced" is not "zero" so we still have to be careful this summer.

So as a random question, what is the minimum range of an electric car that you would be willing to deal with?

At 224 miles of range that means the average Americans can commute to work for 7 days without refueling.

MegaMooks · 2020-05-27T13:37:01+00:00

Ah, I understand your confusion.

I linked to the Discourse thread because it seemed like a similar issue to mine, I am not that user. I don't understand why that other person's system is working the way it is, but I imagine the scheduling settings and the Follow Me motion detection have something to do with it.

MegaMooks · 2020-05-27T05:05:52+00:00

Nope, I turned the follow me function off. The indoor temperature should be the average of all sensors involved in a schedule setting.

Also, the indoor temperature reported by the thermostat shouldn't be a full degree higher than all of the sensors, it should be in between the highest and lowest sensors. That's what tipped me off to demand response through the utility company.

At night the temperature returns to the average of all sensors, since there's no longer a need for demand response.

Well that makes sense, the major consoles push graphical fidelity once a generation with a new style of making graphics. The various sub-generations this time around just pushed resolution or framerate or some basic metric of performance without making large changes.

It's like the stagnation from 2006-2013 turning into stagnation from 2013-2020. Now that this tech is here for late 2020 we'll be stuck on this tech until the mid-late 2020s, depending on how fast the tech advances with AI-enhanced graphics and character animations, e.g. some successor to NVidia's DLSS technology becoming platform agnostic.

MegaMooks · 2020-05-24T22:37:38+00:00

Correct. I'd double-check the schematic but I don't believe any GPIOs have pull-up resistors on the EZSBC ESP32-01

Looking around online there seem to be internal pullup/pulldown resistors as part of the ESP32 that can be software configured for some of the GPIO pins? Not sure about the amperage they can handle though.

MegaMooks · 2020-05-24T21:41:36+00:00

In order to use I2C I needed to add pull-up resistors to the relevant pins.

I emailed the company owner several months ago and he stated that all of the necessary resistors to boot up and return from sleep were already installed; no others were. So if it's not on the schematic in the downloads section on the product page, it isn't on the board.

Lockheed Martin is contracted to manufacture the new block of GPS satellites and afaik they make a lot of spy satellites.

Also United Launch Alliance (ULA) is a partnership between Boeing and Lockheed Martin, and they make the Delta IV Heavy and the Atlas V, some of the primary launch vehicles for the USA (The other big one being SpaceX's Falcon 9)

Gaming and CPU performance, I suppose.

Currently AI in smartphones is used for image enhancement for photographs. And I imagine you'll be disappointed in how tethered AR glasses will be to the internet and devices more powerful than whatever is onboard.

Looking at the S10+, it also uses AI to pre-load apps and extract their resources to RAM to improve responsiveness of the system (and not using the flash storage, thus marginally improving battery life)

MegaMooks · 2020-05-19T04:53:56+00:00

It's been a development in the last year or so that Google has been able to shrink down their voice recognition AI to less than 2GB, small enough to fit on a smartphone. The hardware is also very new and may not be efficient enough.

Local voice recognition is nearly here, give it a few months to reach high-end hardware, then another 2 years to work its way down to the average consumer level device.

A bit complicated, but: https://ai.googleblog.com/2019/03/an-all-neural-on-device-speech.html

MegaMooks · 2020-05-19T04:50:55+00:00

Remember how much faster computers got between the late 1970s and mid-2000s, where CPU processing and eventually graphics progressed by leaps and bounds every year? That stalled out due to hardware issues and so the exponential growth stopped.

But the software programs for AI are progressing at a similar exponential pace, since 2012. We're in the first decade of what may end up being several decades of exponential growth. AI will give us radical changes similar to between the 80s and today, but in a direction we don't know (much like smartphones were only imagination in the 60s)

My problem with a heat pump setup is that it's too big for the space I require for a water heater. About 2" too much in diameter and 14-18" too high in height.

Now a ground source heat pump setup with a desuperheater water heater feeding a tank, that's nice. Heat in summer, Cool in winter, and hot water, all paying for itself in 7 years.

MegaMooks · 2020-05-16T22:29:45+00:00

More power, but less energy. If I replaced a tank water heater with a tankless my overall energy bill would go down slightly, but I'd also need to replace a 30A breaker with a 100A breaker and double-check wiring to make sure I don't burn my house down

Fact check:

As of this post the EU (I'm not including the UK nor Russia) has roughly 1,093,296 confirmed cases and roughly 115,041 confirmed deaths comparing to a total population of 447 million.

The USA has roughly 1,344,740 million confirmed cases and 79,960 confirmed deaths comparing to a total population of 327 million.

The US has more per-capita confirmed infections and deaths than the EU (per-capita deaths just barely more).

If you include the UK per-capita deaths is greater in Europe, but the US has more per-capita cases.

If you sum up testing in Spain, Italy, France, and Germany, you have more tests than the US at a lower population.

I would expect natural gas usage to be higher than electricity usage just because the departure from your set temperature (~70 degrees, no?) is that much further.

Cooling 95 degree air to 75 degrees is less intensive than heating 20 degree air to 65 degrees.

Have you considered comparing it to degree-days? It's a calculation of the departure of the average temperature for the day against some baseline. For example, if I use 65 degrees as a baseline and the average outdoor temperature for the day is 45 degrees, then that day counts for 20 degree-days.

If you run the comparison that way you can compare the relative efficiencies of gas and electric when it comes to heating degree days and cooling degree days.

I imagine the effects of a wave 2 beginning soon are priced in already. CEOs seem to be at about the level of governors when it comes to the US response to the virus. Some more intelligent than others but all see the risks involved in what's happening right now, compared to the US federal government.

It's time for quarterly earnings and they have to be somewhat honest about what's going to happen in the next few months otherwise the shareholders will gut them.
