That's actually a pretty slick idea not gonna lie. If I ever de-Google, that might be the way I go.
I like to travel with a Chromecast and a mini router so I can do TV stuff away from home.
Now I'm wondering, I know that USB stick computers have existed for awhile. I'm wondering... Does something similar in size to the Chromecast exist? Something just powerful enough to stream whatever I want to a TV with whatever software I can load on it? Hmm...
That's a bummer, but makes sense.
That's cool. Is there an option for "casting" type software to emulate a Chromecast? I like choosing stuff on my phone and sending it to the TV
I agree with you on this point completely. The article is pretty garbage. But that's not what your original comment seemed to imply. It seemed like you were saying everyone should know this stuff so why should any article exist on the subject.
I think that's why everyone is so worked up.
Oh that's fair, yeah especially on Linux
Well I think of the people who have 4K stuff (I don't), there's probably a lot of gamers who have 4K monitors by not TVs? Just guessing, IDK 🤷♂️
Do you not have a TV? I've watched stuff on my monitor, sure, but sitting on the couch watching TV is what the vast majority of people do.
Unless you mean connecting your computer to your TV? I did this for awhile, there are ways to make it work, but I much prefer using a Chromecast or similar device to simplify the whole interaction.
So tasty. No way I can make it myself, but the local Indian restaurant makes it amazingly.
It was about that time I realized....
I'm not vegan, but I love me some Baigan Bharta!
Everyone has to learn something for the first time. Today's 10,000 and all that.
That's what I said the second I saw it. Too big to be practically portable, for me anyway. So it's basically a bigger steam deck that you only use at home. Not a bad idea, but not worth what they are charging for it, not for me anyway.
Lately I've been using an 8 year old 13" Chromebook and an old xbone controller to stream steam games from my PC to my couch.
No it's not portable, but it's all I would use it for anyway, and it cost me nothing but the parts I had laying around. Anyone else could probably do the same thing for just $100-200. Not $1000+.
I'm not against buying new stuff, and new technology. But it's not always needed. For me anyway 🤷♂️
I was reading along like, that's dumb but at least I could craft something in my password man-... Oh.. oh no..
The problem that I see is that unless that magic semiconductor is 100% efficient, turning all the heat energy into electrical energy, then there's gonna be some left over, and things are gonna get too hot too fast too furious. So you'll need to cool the thing, or part of it, maybe similar to a TEG using the Seebeck or Peltier effect?
I have a few of these kicking around somewhere. They work, just not super efficient, at all, with current technology.
My point is I feel like no matter what you're gonna need extra parts to cool the thing. Water pumps etc etc. Why not just use steam? 🤷♂️
Edit: nice diagram though!
Would this include things like the contents of messages?
I know it's not end to end encrypted, but if they're just gonna search the whole database for keywords, and then decide I'm of interest because I joked about abc or admitted to xyz in a private chat, then that's a load of crap.
Amateur radio is fun. Cheap to get into, but gets a bit expensive pretty fast.
But, you can talk to people all over the world with nothing but a bit of wire strung up in a tree. No million dollars worth of computers and infrastructure between you, no. Just two people, two radios, two pieces of wire in two trees. It's crazy that it works at all but it does!
Getting a license costs something like $30-40 bucks I think. Used to be free even just a few years ago, but now they've added fees to get it.
You can get into a handheld radio that'll let you talk to your local group of people for $20-30, that'll get you say... 50-100 miles with repeaters. More if they are linked.
If you wanna go further, you've gotta go to lower frequencies. A low power HF radio can be had as cheap as $80-100 ish. You can technically talk around the world with it, but at only 5 watts, it'll be tough to do unless conditions are just right. People do it all the time, but it's a challenge, a skill to learn.
$300-400 ish gets you into a 20 watt HF radio, that'll do significantly better, and actually that's the radio I use most the time when I go out hiking with a plan on operating in the woods. For this price you could also get an older tube or hybrid radio that is 100-130 watts, but the learning curve can be a little steep, they are big and heavy, and even if you know what you're doing, they can be a but less convenient than modern radios. Not that there's anything wrong with them, one of my first radios was one of this type, I bought it broken and fixed it, I still own it.
$800-1000 gets you all the radio most people ever need. Modern digital HF radio, 100 watts, plenty of bells and whistles, practically operates itself. People can and do talk all around the world on 100 watts all the time. Though at this point I have to admit, even with this amount of power, it can be a challenge to talk to the furthest people unless conditions are just right.
Ok, so more power, right? Well, yes, you can do that. The legal limit in the USA is 1500 watts. But there's a few things to consider about that.
First, yes, more power will make your signal go further. That's true. But when you're trying to reach the furthest people, often times it's your ability to hear the other person, that's more important. In the hobby they say you don't want to be an alligator, all mouth, no ears. It doesn't matter how well the other guy hears you, if you can't hear him, then you aren't communicating.
The answer? A better antenna. That wire in a tree does wonders. Honestly, one of my first and most memorable long distance contacts was from lower Michigan to Japan, with 100 watts and a wire in a tree. Almost 7000 miles. Honestly, it was amazing. But later I would make similar contacts semi-frequently, by using a directional antenna called a yagi.
They cost about $500-1000 for the smaller ones, bigger and better gets into the thousands, not counting the minimum 30 foot tower to put it on. Thankfully mine was gifted to me, it was in bad condition, stored in a crawlspace under a house. But I cleaned and repaired it with 3d printed parts. And I had an old TV tower that I put it on, instead of buying and building one. All free.
The way it works is by taking the radio energy and focusing it all one direction. Kind of like how the lightbulb in a cars headlamp is very bright by itself, but put inside the special housing in the car, it gets focused so you can see further down the road. It's the same energy, just focused.
My antenna had a gain of 8dB. What that means is that whatever direction I was pointing it, it took the 100 watts from my radio, and essentially focused it into a 600 watt beam of radio waves. (There's more to it than that, but I'm fudging some of the details here for ease of understanding).
Now the beauty of this is that it works in both ways. So if I'm pointing it at Japan, and the guy over there is only pumping out 100 watts, then from my perspective, it's almost like he's using 600 watts. See how that's better? Now we're both louder! (Again, details fudged here).
Now if you take an antenna like that, and pump 600 or 1200 watts into it (those are the sizes of the two amplifiers I have), then your effective output in that one direction is more like 3800 or 7500 watts! That kind of power really does make a difference, a lot of the time. So, why not even more!
Well, here's where we come back to earth a bit. Yes more power is better. But there are diminishing returns. Radio signals are like sound waves, in the sense that the decibel scale is logarithmic. Twice the power does not get you twice the loudness.
This is too hard to explain without you having a frame of reference, but.. basically, the improvement in signal you get by going from a 5 watt radio to a hundred watt radio, well, it's pretty significant, right? It takes something difficult to hear, and makes it much easier.
Well, the increase between those two powers, is over 13 decibels. Now, in order to get that same "Wow, now that's much better!" Improvement? You'd need another 13 decibels. But to do that, you'd need to go from 100 watts, to, well, an illegal output of 2000 watts. The next 13 decibels would require jumping up to 40,000 watts! Decidedly illegal. And you wouldn't want to stand next to it haha.
So while amplifiers do help, especially when paired with good antennas. Most people don't bother using them because they usually cost around and over a thousand dollars, or more, for the 600-1000 watt ones. The 1500 watt ones are even more expensive. And you have to upgrade everything else in your equipment to handle the extra power. And for what? A bit better signal?
Don't get me wrong, I use them. But, not always 🤷♂️ and I have no desire for a legal limit amplifier, not unless I had money to burn.
A good antenna is a much better investment, though doing that right can get very expensive very fast.
Anywho, sorry for the long post, guess I kind of got carried away. I didn't even cover half the stuff we do. POTA, SOTA, Field Day, email and SMS, GPS tracking, satellites, moon bounce, meteor scatter, the role of the sun and ionosphere. Grey line propagation. Fox hunting (not actual foxes), including TDOA. Digital modes like FT8 and APRS, FreeDV, SSTV. Morse code is alive and thriving. Building and fixing radios, building and designing antennas. All that and so much more.
If you have any interest in technology at all, do yourself a favor and at least look into ham radio. It's literally a license to play with science stuff. And while a lot of it can be expensive, as I've described. A lot of it really isn't, and most of the fun I have is with stuff I've made, not bought.
Thanks. I'll look into it, I've got plans to repurpose an old wiiu into a deck-like couch gaming machine.
Right now my wife is using the Deck pretty heavily, so I'm using steam to stream a game to my old Chromebook, it's working pretty well actually 🤷♂️
Is this better than steams built in streaming system?
Honest question, never used anything else
Hmm maybe I'll have to look into it again. I remember trying it once a year or two ago, and running into some known bug where it looked like it was gonna work, but never did. Updates happen though. I'm fine with doing it from desktop mode, if it works. Kludgy, but I can understand it's not a priority to implement.
Have they still not fixed or properly implemented adhoc Wi-Fi yet? Seems like a fairly big deal. Especially if you and your spouse are on a plane or train or something.
I mean, you could always use one of those pocket Wi-Fi routers. I keep one in my travel bag at all times for hotel Wi-Fi that tries to limit the number of devices, and to bypass the Wi-Fi login screen for my Chromecast that I also keep with me.
I love the steam deck, and recently, so does my wife! Don't get me wrong, I couldn't be happier. And she would find something to play on her switch if I asked for the deck back. But I don't want to stifle this new found love for the deck.
So I decided to get creative. What you're seeing is horizon forbidden West on maximum settings, streaming from my desktop to an over 8 year old Chromebook, with an Xbox controller.
It's honestly pretty good, considering. Every minute or two I get some hitching and stuttering, something to do with the Wi-Fi. Also there's a weird green bar at the bottom I can't seem to remove 🤔 But otherwise it's smooth and clear. Good enough to get me through until we can justify a second Deck 😬
I'm surprised it works at all! But it's steams built in streaming, when the Chromebook steam app 🤷♂️
Edit: in case anyone comes by later and wants to know or could find this useful: the Chromebook is an Acer R13 from 2016, mediatek CPU. My wifi is a 1st gen Google WiFi puck. And the stuttering started turning into zero audio at times.
I bought a random $15 gigabit Ethernet USB C adapter with pass through charging, ran cat 6 tm under my couch to where I sit, and now things run 99.9% smooth. Very pleased. This will hold me over until I can justify another steam deck.
Edit 2: I fixed the green bar by realizing I was an idiot. I never looked at my PC when it was streaming, and it was using my crappy secondary display at 1400x900. This Chromebook is 1920x1080, so it was doing weird things. Moved it to my main display at 1080, and now it looks even better, and no more green bar.
Cat tax: ! That's not a small pineapple, he's just a big cat.
I'm cheap, and I also have barely any time for breakfast in the morning, and my wife likes it when I make her breakfast but she leaves for work an hour after me.
So this is what I do, and have done for almost three years straight now.
You get yourself some !fully cooked frozen chicken patties Some !small flour tortillas And a big bag of shredded cheese, your choice
First thing I do when I walk into the kitchen is start the toaster oven, getting it hot. Then I take a chicken patty out of the freezer and break it in half on the edge of the counter while it's still in the bag. Then I take a half sheet paper towel, and fold it in half, because I hate doing dishes. I put both halves of the chicken patty on it, pop it in the microwave for one minute, 30 seconds per half if I'm only doing one. Then while that's going, I slap two tortillas on the counter, sprinkle a healthy dose of cheese on them and spread it out evenly. By the time I'm done, so is the chicken, so I put each half on one side of each tortilla. Next comes the flavor. You can sprinkle a little garlic salt and pepper, or a dash of worcestershire, or my favorite was a dab of Chick-fil-A sauce under the patty. Then, slide it onto the rack in the piping hot toaster oven. Then I walk away to go start getting ready for work, just a simple task like finding socks or something, then I come back a minute or two later and the cheese is nice and bubbly, the tortilla is browning on the edges, it's just about ready to pull out. Then I pull them out, fold them in half, put mine on my water bottle to cool, and hers goes back into the toaster oven, but it's a fancy oven so I set the temp to 160f so it's nice and hot when she gets up, but doesn't keep cooking too much.
The whole process takes less than 10 minutes, maybe even 5 minutes if I'm really on my game in the morning.
The whole thing costs like 50 cents, and is plenty filling for me. It's probably not the healthiest option, but.. 🤷♂️
Why don't I use something more breakfasty, like sausage? Because I can't find it as cheap as the chicken. Funny enough, I actually started this whole process during COVID, with frozen precooked sausage patties. We got a bag of them with one of our low income commodity boxes, and couldn't figure out what to do with them. So I started doing this. Then when the bag ran dry, I transitioned to chicken. Not as good, but still good, and like I said, I'm cheap lol.
I'm going to do some a/b testing to compare to the rubber duck antennas I've been using. I don't expect much more, but perhaps a little bit more range?
Going from the little stubby coil of wire included with the heltec v3s, this should be amazing.
!Smith chart showing resonance at 907mhz
Edit: I tested it and it works just fine, or at least within the margin of error of my test. It wasn't significantly better or worse than the Amazon bought high gain rubber duck antennas, a little disappointing but 🤷♂️
As has been said before, height is might. Line of sight counts for more than increased power.
I'll still probably use them on some permanent nodes 🤷♂️
Just putting this here in case it's useful to someone else.
I'm still working on setting up my local nodes and meshing to my buddies houses. Part of my testing involved going to the top of the tallest hill in my town, (1300 feet above ground level, the rest of the ground is relatively flat around here).
The problem was that I couldn't connect to my home node, around 2.5 miles away, good line of sight. Testing showed that my home node received all my messages, but the return confirmations never made it back.
The problem? The tallest hill in town is also home to two fully loaded cell towers, blasting away, presumably deafening my node, overloading the front end with strong out of band signals. 900mhz GSM perhaps?
At any rate, I looked into band pass filters. I'm a ham and I've dealt with poorly filtered front ends by the likes of baofeng, so I know filtering can do a lot, and I wasn't sure how much a standard node came with.
The answer? Some, not much. Enough for most use cases. Oddly, most information I found on the subject, specific to Lora, advocated against using filters, saying they are usually unnecessary, etc etc.
While that's probably true most of the time, it's definitely not true all of the time. I'd be interested to see some a/b comparisons of 20-40 foot high nodes in urban environments, both with and without filters.
From experience I know that a baofeng 144mhz radio (known to have poor filtering) with a 1/4 wave vertical antenna up 40 feet, was mostly deaf to any distant signals, and actually performed better in some instances by just using the stock antenna and standing on the ground. Likewise when using the 40 foot tall antenna and adding a filter, the reception was massively improved.
Add to that experience my most recent test. I added a 915mhz band pass filter to my node and brought it on top of the hill, next to the cell towers, and was able to make full duplex communication with my home node.
I'll be doing more testing, some a/b testing with the filter on my home node to see if it improves my range tests.
Filters probably aren't for everyone. And they aren't free performance gains, you can't forget insertion loss. But don't be afraid to buy one and try it if you think you might be having desense issues.
It was supposed to rain, but we pressed on, and it ended up being beautiful. Chilly but pleasant. Just cold enough to make you appreciate the warm fire. Plus the sound of the river to lull you to sleep.
Hard to beat!
I usually go with dehydrated meals, but packed heavy on real food this time, for science. I got myself a small lightweight nonstick pan, and fried up a whole steak for dinner, bacon and eggs for first breakfast, and pancakes and eggs for the second breakfast. I only had one dehydrated meal this trip. I learned a lot!

Hear me out. I've been thinking about the best way to put up solar nodes in my area.
I live in Michigan so the winters are long and usually cold, and can get quite cold on occasion. Less so these days, but still. We all know that lithium doesn't like to be charged below 32f, so that's a problem.
I have one idea for a remote node on my property, to just use a 6v sealed lead acid with a 6v solar trickle charger, maybe a diode in series to the node if the voltage from the panel threatens to go over 7 or 8 volts. Or some kind of shunt, idk that idea isn't fully baked.
I'm also looking into a thermostatically controlled resistive heater. Bump up the capacity of the battery and make sure the panel is big enough to run the heater non-stop if need be. But that idea is also still baking, parts are in the mail and prototyping is yet to be done.
But then I had another idea. What about super capacitors? You can get a 5.5v 10F super capacitor on Amazon for $6. Some chatgpt math (and a proper understanding of the difference between power and energy, or rather ma vs mah) tells me that the storage 10F at 5 ish volts is equal to a nominal lipo at 3.7v and 10mah. Ignoring the fact that the capacitors voltage would drop sooner, and thus you'd lose some energy on the bottom end...
The T114 v2 has a built in solar charger circuit, a standby current of 9ma, and a TX draw of 150ma. So with a super capacitor you could get roughly an hour of idle time, or 4 solid ish minutes of nonstop transmitting. That's more than enough to account for a big cloud passing by, especially if you beefed up the solar panel, or easier yet just doubled or tripled the capacitors, they are pretty small.
The charging circuit might not like the low internal resistance of an empty capacitor every sunrise, but a couple ohm resistor in series would probably solve that.
Yes it's not ideal to have your nodes turning off every night, especially in the winter when days are short to begin with. But could it technically work? I feel like it could technically work. It'd be great in the summer,
My only concern would be the node getting stuck in a weird state if the sky is cloudy and the CPU browns out. It'd take a whole day to power cycle. Probably put a megohm resistor across the capacitor to ensure that it drains fully overnight in that scenario.
Are there any concerns with constantly hard power cycling a node like that? Data corruption?
The lead acid is probably the safest solution, though heavy. And the heater is probably the most compact solution, though more complicated and prone to catastrophic failure. But maybe there is room for super capacitors?
Sorry for the wall of text. Just spit balling.
Edit: HOLD THE PHONE! You can get 500F caps for $7! The reviews say they're actually more like 300F, but even that could idle a node for well over 24 hours, and TX nonstop for 2 hours, which is unlikely to happen. This is a game changer. This could solve the winter lithium problem.. I'm going to try this and I'll report back.
Edit 2: Various super caps and LiCs still on order. But I just came across this in the discord:
"Dendritic degradation happens when charging below freezing. However it’s a slow process. And the slower the charge, the longer the lifetime. With IoT devices the charge rate is quite low and not as critical compared to higher draw devices. Up here winters reach -40 sometimes, and in a lot of cases it sits below freezing for weeks, even months at a time. We’re now in our second winter on the same batteries with no failures (yet). Regular lithium Ion and LiPo. I’ve only done LTO for high traffic nodes that are very hard to access. Otherwise just plan to replace them when they die.
Slower the charge rate / the higher the capacity / the newer the battery / the better the quality the battery, all compound into longer cold weather performance.
There’s other factors too, like the higher the charge rate usually means the more sun/solar activity, which also means if you have a properly setup enclosure, the sun hitting it can be enough to increase the temp by over +20c or even more. This also doesn’t account for the charge/discharge heat being released by the batteries themselves in the enclosure." -Cully@KBOXLabs
So it seems to me I'm overthinking this whole thing.
Maybe a super cap or LiC would be good for extreme longevity. But a decent pair of 18650s might be plenty for something you won't have to touch for a couple years 🤷♂️
I'll still do some testing and report back, but I might not spend the extra money making each node supercapped.
I'm still fighting with Amazon to get my first pair of devices delivered, I went with heltec v3s to get started.
But looking at the meshmap.net, it's very very sparse around me. How likely is it that the are nodes that aren't on the map?
Hopefully I can check it out myself soon!
I'm trying to configure the gyro to help me aim. I've tried every configuration I can think of, or find online. I'm slamming head into a wall.
From what I can tell, the game now only accepts "steam controller" input. Which means the right joystick isn't actually a joystick, it's a weird virtual joystick, and there's some conversion going on. So when the old methods for getting gyro input are used, ie "as joystick" or "as mouse", the input is completely ignored by the game.
I've tried configuring a fresh controller configuration based on a standard controller, but then the game things I'm trying to use a keyboard and mouse and ignores all controller input.
Now, if I set gyro to "right stick (steam controller logo)", then suddenly the gyro starts affecting the right stick. But instead of being a relative input, as in when I pull the left trigger to aim, use the current gyro position as zero, and all relative movement should be applied to the stick. Instead it is an absolute value, with the movement being relative to the calibrated location of gravity down. So when I pull the left trigger, I immediately stare into the sky.
I think the solution to this is the "auto world tilt" option, but that is only available in the "gyro to joystick" configuration, which of course doesn't work.
Am I missing something completely obvious here? Can someone please guide me in the right direction? I miss gyro aim.
Thanks
Hi there, I've been wanting a framework for awhile now, just haven't pulled the trigger yet. I was perusing the website today, comparing the price and performance of different configurations, when I realized that the 16 needs a 100w power adapter, 180w if you've got the graphics card.
This is a dumb question, because obviously it would charge fine with the lid closed and idling or turned off. Or I could just upgrade my power adapters. But I have a lot of 65w USB C PD chargers in my house and cars, and I was wondering if anyone has tried using them, and if so how effective is it?
Like, 180w is a lot of power. If I'm just working on spreadsheets or something, I'm imagining it would charge just fine? Under a heavier load I would probably start to slip backwards? Where's the line? Movie watching? Light gaming?
Just food for discussion I guess, I still haven't pulled the trigger haha.
Thanks!
The civet processed beans? I'm wondering if it's all hype? Or worth buying a bag to try?
Edit: Thanks for the responses everyone! I'm gonna pass on it 👍
I'm new to backpacking, did my first trip this year with a hammock and had a great time.
Trying to get my wife into it with me. We're planning on going to Iceland in September, no trees. Plus she sleeps cold so she'll probably be more comfortable if we're in the same tent.
I'm looking to spend as little as possible, we're really not sure this will be our thing going forward, it might just be something I do solo. And we already have a big six person tent for glamping with a big air mattress.
I'm hoping for under $200, less if possible.
But I also don't wanna buy garbage, or carry something excessively heavy.
Suggestions?
