Establishing a permanent lunar base is the logical first step towards a Mars trip.
Establishing a permanent lunar base is the logical first step towards going anywhere in the solar system; Mars, Venus, the asteroids, Earth-Moon Lagrange points, etc,
Bought a car stereo a little over 2 years ago, the stereo system could either connect to bluetooth, or use a USB device. Connected my phone to bluetooth, it didn't sound right. Couldn't put my finger on it, but it sounded thin. Put the same music on a USB device, it sounds just fine.
I've read, but cannot confirm, that the problem is that compressed music on your cell phone is decompressed and then recompressed and decompressed again over Bluetooth.
The problem is that the compression algorithms are designed to emphasize and de-emphasize different music characteristics. So it's kind-of like squeezing your music through two incompatible audio filters, it just squeezes all the goodness from your music.
In fact, I don't know but I'm willing to bet the Bluetooth compression is optimized for speech, which would be crap for music.
You would need an ESP module like the ESP-07 or ESP-12 with multiple I/O pins or a NodeMCU board to drive the display, but you can program it to sync with a time server every day or so over your wireless network.
You can add a DS3231 precision real time clock chip (cheap breakout boards are available on eBay) for better accuracy.
No one for a thousand years to come will ever seriously think about trying to smush two protons together hard enough for them to fuse without a sun-sized gravity well to assist with it.
Actually you can do it relatively easily with a Farnsworth fusor.
It's not practical for power generation, but it easily smushes protons together.
Yes, I know TFS says, "the three best-selling vehicles in the U.S. in both 2014 and 2015 were all pickup trucks."
But I would think a luxury SUV would be a more likely step.
Musk has made great improvements to battery capacity and life for his automobiles, but I suspect trucks require more power and range than is practical with current battery technology.
Stereo lithography has (had?) been used for decades to prototype various 3D parts for fit and interference, though it could not make structural parts, certainly not for high temperature applications.
SpaceX's SuperDraco engine is completely 3D printed, although I'm not sure of the exact technology.
"First, it's important to note that despite a 3-2 vote approving the Title II-based rules, we won't get to see the actual rules today. Despite claims by neutrality opponents that this is some secret cabal specific to net neutrality, the agency historically has never released rules it votes on (pdf) until well after the actual vote. It's a dumb restriction that's absolutely deadly to open discourse, but it's not unique to one party or to this specific issue."
There's only one place in the article that specifically mentions mobile broadband. The rest talks about the internet and broadband in general.
Although it's not completely clear, I'm assuming Title II will apply to both mobile and non-mobile broadband, but he's calling out mobile broadband because the most ignominious examples of abuse (data caps, throttling, prioritization, etc) have been by mobile operators.
Electronics? Really? Those are just things. They can be replaced.
There's electronics and there's electronics.
Sure you don't care about your computer, TV, DVD player, etc, etc, but you might want to add a crank/solar AM/FM radio, flashlight, spare cell phone and maybe even a battery-operated TV to your stash.
Depends on whether your flashlights are compatible with lithiums. For example, they will cook a maglight with incandescent bulbs. The bulbs burn out within 10 minutes.
You're thinking of Lithium-Ion batteries which are nominally 3.6V.
Energizer Lithium batteries are 1.5V and are compatible with most electronics that take AA or AAA Alkaline batteries.
this kind of ruling encourages multinationals to never set up business in the USA.
I'm not sure it's quite that bad.
IANAL, but I can imagine a foreign corporation setting up a wholly-owned subsidiary in the USA.
Of course US operations would be subject to legal warrants and subpoenas, but all foreign operations should be outside the reach of US legal authority.
If a warrant is served for data from the foreign operations... sorry, the US subsidiary doesn't have access to it. It doesn't matter how many people they throw in jail for contempt.
That is, if you're going to send a remotely guided robot to the moon, is a bipedal walker the best choice?
As opposed to a conventional wheeled or even a quadrupedal rover.
I assume a bipedal walker is going to need sophisticated stability control (computational and mechanical) for every step it takes over rough terrain that a simple wheeled vehicle can just roll over.

Elon's got you covered.

Musk's not going to "sit on [his] laurels" at least until he steps onto the surface of Mars.
So we've got a ways to go.
SpaceX plans worldwide satellite Internet with low latency, gigabit speed
> The problem remains with the "tubes" which have to be a very good vacuum over a long distance.
That and the thermal expansion and contraction of the metal tubes extending over kilometers which must remain vacuum tight and well aligned.
Good luck with that.

An ESP8266 module with an LCD or LED display.

Farnsworth fusors work just fine at room temperature.
In the default configuration the phrase "Powered by Zencart" appears at the bottom of each page.
Also, the default Zencart themes and icons are unmistakable if you know what they look like.
Unless the washing machine was defined as static.
Then there would be one washing machine for every sock in the world.

They're working on it.
My bad, but I think it was a reasonable assumption.
If you don't mind me asking, how many cells were in the flashlight?
I assume two, but there I go jumping to conclusions again.
There's electronics and there's electronics.

Extra points for a CB or Ham radio.

But what do I know.
And it's all legal, according to their interpretation of the law.
You forgot that part.
Well, they already have autonomous vehicles and if they can add autonomy to "Atlas", then they can replace FedEx and UPS package delivery.
Although that's something I'd expect Amazon to experiment with.
If I understand your question correctly, the answer is a fuel-cell.
And yes, they're working on it.

I'm looking forward to the remake of "Christine" with a truck the size of a house in the title role.
More like a remake of Killdozer.
