One of the biggest hurdles in upgrading or modifying the HP 14-an013nr is just getting the case open. HP doesn’t have any incentive to make this easy, they want to sell you more computers, having you upgrading them interferes with that.
Happy Hacker’s Notebook: Mysteries of the HP 14-an013nr: RAM
In the video “AICvideo” expresses the opinion that more than 8GB of memory is unnecessary in this machine because of the limited processor power. I’m don’t really have an opinion about that yet, but it’s worth noting that because of the integrated graphics the system memory is also the graphics memory, and it does have a full-HD screen, which is a lot more pixels to drive from memory than most notebooks this size.
The PirateBox Pi Papoose
The basic idea is that you’ll be able to walk into a coffeehouse or take a table on the sidewalk somewhere, pull out a notebook computer with some electronic bits stuck somehow to the back of the lid (very cyberpunk aesthetic, sort of like a DeLorean with high-tech stuff stuck on the outside), have PirateBox up and running in the background to entice other folks around to log in and share whatever while you work on the notebook and on the Internet in the foreground, but you’re still able to connect to the PirateBox, monitor and control things there from the notebook.
Emergency one-person survival stove- the best choice is alcohol, 91% of the time.
So, we have trail equipment stores, hardware stores of various types, liquor stores, drug stores, convenience stores, grocery stores, boating equipment stores and marinas as possible sources if you’re afoot on your own. That’s pretty versatile. I don’t think any other liquid fuel comes close, unless you’re willing to use automotive gasoline, which requires special stoves and a lot of ventilation and there’s still danger.
Power Requirements for the Raspberry Pi Zero W
What this means is that pretty much any USB jack will supply plenty of power to run a Raspberry Pi Zero or W at full load, even with Wifi and Bluetooth.
Powering the Raspberry Pi Zero W Through its USB Data Jack
It is possible, in fact routine, to power the Raspberry Pi Zero (and the Raspberry Pi Zero W) through its USB data jack.
Surprise, surprise… survival on Mars will require generalists and appropriate tech, not specialists and high tech.
None of these general thoughts should come as a surprise. Survival on Earth has almost always implied stepping down from whatever level of technology has failed to a level that still works. It’s one of the most fundamental principles, and a reason that the line between “survivalism” and interest in various forms of primitive technology is so blurred.
Survival – Tip – DIY Ranger/Pace Counting Beads, My Current Configuration
I’ve set up a slightly unconventional configuration for my own ranger beads, and I’ll describe here what I’ve done and why.
Survival – Tip – Real DIY Ranger/Pace Counting Beads
Beveled faucet washers make good sense too. If you think about it their normal use requires to resist abrasion and to be constantly immersed in water without ill effect, so they have to be durable and reasonably weatherproof. I have no idea what their ultra-violet (UV) light resistance is like over long periods, it’s probably fine, but if you’re worried you can always hit them with a little spray of Armor-All or similar plastic/rubber preservative, that’s what it’s designed for.
Kevin Kelly’s Cool Tools
I subscribed to the mailing list as soon as it started, and while the quality has varied somewhat and there have been times when I felt that it wandered too far into non-utilitarian (non-useful) selections, I’ve never been tempted to un-subscribe, and I’ve learned of a great many useful things from it that I wouldn’t have otherwise known about.
DIY SM7b microphone?
Maybe this dynamic microphone classic is worth the $400 price tag, “Made in Mexico” and all. Maybe not. It has certainly proven itself many times over. Thing is, I’ve got no business owning one even at a quarter of that price. I’ve got negligible microphone experience in recent decades (when I last sang on stage the Electro-Voice EV664 was the mic of choice- ancient history). There’s no way I can remotely justify spending $400 (not to mention $150 for a Cloudlifter CL1, which seems to be the “trick” setup) on this thing.
Of course, I still want one.
Gear Lust – The Zoom H6
There are things that are very cool functionally but aren’t impressive to look at, and there are things that are cool to look at but not impressive functionally.
In the first category I think first of the Raspberry Pi single-board computer. There is a ton of potential in these little things, but you really have to know what it is and then think about what you can do with it to really appreciate that. To the eye, it’s just a very small circuit board, it doesn’t look particularly interesting, much less cool.
In the second category I think first of the prop-replica field, and especially the sort of stuff that Adam Savage turns out in Youtube videos. These look very, very cool, but it’s all skin-deep, the bottom line is that they may look and sound and even to some degree act as though it does something really interesting, but it’s all “a tale. Told by an idiot, full of sound and fury, Signifying nothing”. It’s basically a toy, a fake… and somehow that really isn’t cool at all.
Creative Anachronism, a Raspberry Pi Vacuum Tube Amp
I really want one of these, though I can’t really justify it. I really have no use for it, or very little. It’s just so bizarre… like a steam locomotive with a computer control console.
It’s a combination of a Raspberry Pi computer and a tube amplifier.
No more relay boards! The IoT Relay from Digital Loggers
IMHO this product deserves to be better known. I’d hate to have it disappear, it’s a great boon for electronic hobbyists in general, in safety and convenience.
Fitbit HR passive access points- no smartphone.
This past Christmas I was given a Fitbit HR*, which I really needed to track activity and heartrate levels. I’ve worn it ever since, and rely on it. The problem is, I don’t use a smartphone. At all. It’s not
