Hi /diy/, for quite a long time I've wanted to make a phone/mp3 arm bracer thing like pic related. I think i played to much Fallout when I was younger or something.

Wearing a phone on your wrist makes using it retarded, so that's out. So I've settled on an iPod Classic 7th gen.
Initially I was just going to make it all out of leather using my current case as a guide, but then I found out about H2O Audio's waterproof iPod covers, meant for swimmers, and fell in love with the concept.
And so Whilst I still plan to make the arm brace itself out of leather (a skill that I've only recently picked up), I figure i could have just attached the case to the leather and done, easy project.

You can read more about them in detail here if interested (a review): https://www.ilounge.com/index.php/reviews/entry/h2o-audio-iv6-waterproof-case-for-the-ipod-classic
The important bit is that they allow for the use of the device whelst it is sealed via the waterproof audio jack gasket, and the mechanical click wheel

Only problem is i've not been able to find one that fits my 7th gen classic. They discontinued them a decade ago, and the only one I could find for sale where for the much smaller ipod mini. It was only $10 at least (which shipping to Europe 3 times that).

And so I want to know what people think the best way to go about making a new case with parts cannibalized from the H2O case. Mainly the Audio jack, Wheel, and hopefully the hinges and locking latch if possible. Ideally the thing could just be lengthened and widened to fit, kinda like how you would cut and sew in a patch in a fat persons trousers, but the way the wheel is in the centre makes doing that awkward.

(Cont.)

though the idea using a phone like a wrist pipboy seems fun, I bet its gonna incredibly clunky and of doubtful usefulness

Maybe with a custom OS you can do it? Fallout has a large community so you'd easily find some devs interested in making an "IRL Fallout OS".

But what do you want to use the phone for? Is it gonna be just used for calls and playing games?

Phones yeah, but in this case its a simple mp3 player :)
Maybe I should have used >>2383590 as the OP image instead, seams to be causing confusion sorry

>>2386686
Iirc, there's a fallout skin thing on android (and maybe ios?), btu really I don't have much need or interest in making one of these for a phone.
My phone is an old iphone brick that i use as a notepad and for taking texts/calls. Not used enouth to warrant this much effort.
The Pip Boy is cool, but unfortunately impractical. This is a nice middle ground between just strapping a touchscreen to my arm and going full on fallout with it. I think.

Hi fren, a while ago I was working on a vaguely similar concept (too much fallout). Instead of using a phone I used a raspi with a touchscreen that mounted directly on the GPIO pins and powered it with a lithium battery iirc.
Dug out the pi for picrel no idea where the battery has gone. I had planned to make my own UI for it to give it less of a desktop look and use it for music via the pi's audio jack or bluetooth.
I ran into issues trying to make a case for the damn thing that was wearable, going at it from the repurposed ipod route is bigger brain, esp combining it with leatherworking (always wanted to learn that).

Keep us updated on progress! :)

There are 18650s with protection built in as well but they’re normally too long to fit in shit that takes regular 18650s.

>>2386560
But when people say “protected” when it comes to lithium cells, they don’t mean it has vents so it doesn’t bulge. “Protected” means over/under voltage and all that.
>>
>>2386589
I knew about the 18650s with built in protection but I didn't know they were longer. Can they still be called 18650 or does that name not have anything to do with the form factor?

>“Protected” means over/under voltage and all that.
Fair enough.
>>
Please don't, this is how fires start. Throw it away and buy a pre-made one.
>>
>>2386597
Yeah they still call them the same shit… sometimes. Like search “18650 battery” on Amazon and you will get pic related, but the description doesn’t say it. Not sure if they’re changing descriptions on some of these button tops because they’re a couple mm longer.

Lots of devices that use the batteries will say somewhere whether to use flat top or button top cells, I think the button top often implies there’s a little protection circuit in there.

I bought one of these cheap arc welders off ebay to learn stick welding for hobby stuff. Now that I have it I'm wondering how safe it is. I assume it's pretty hard to mess up an arc welder since people make them out of microwaves and car batteries and shit, but how can I be sure this thing won't electrocute me when I use it?
>>
>>2386477
It should be safe, voltages on welders are generally don't output high voltage and don't run full amps before striking the arc and you'll weld on DC as well which is safer than AC. You might feel a buzz if you load a new electrode with wet gloves but it won't cause damage.
>>
>>2386477
If you have a multi meter, put it in continuity mode and put one probe on the earth pin of the mains plug and the other probe on some exposed metal of the case, there should be very low or no resistance. If it's open or high resistance, it's potentially dangerous.
>>
>>2386477
>Now that I have it I'm wondering how safe it is
Safe enough usually.
> but how can I be sure this thing won't electrocute me when I use it?
Stick welders can electrocute people. My welder has OVC of 75V and it sometimes shocks me. So use gloves etc.
>>2386591
If you feel buzz it is not safe. There is a reason some welders have VRD mode

Why the fuck it is pain in the ass to stick weld 5/8 OD (16 mm) EMT? 1mm thick.
First I tried 6013s. Didn't work out that well, because slag was getting in front of weld puddle, was getting into the seam between pipes causing lack of fusion.
Then I used 6010/11s, day and night difference, no slag bullshit, and it actually welded two pieces together... If only I was better at using them.
Also tried texas tig, as i couldn't fit shit up nicely. Kinda liked the technique, was kinda satisfying to shove steel wire into the puddle and see it grow.

Can anyone explain why do 6011s work so much better for thin metal stuff? When to use which electrodes?

Because I don't know when to use which shit really. I wish i kinda picked up 6011s first, not 6013s.

But hey, booger welds hold world together I guess.

Well, you're fucked, there's a target on your head. If you didn't any of this, a simple bottle of petrol and a box of matches could solve this.

If we end up in a barter system what would be the most useful stuff to 3d print ahead of time for tradeabilty/usefulness? I was thinking of just starting a small box of things that might come in handy later that might be in high demand / hard to find. Any ideas? I already printed 5 solid knuckledusters, could probably trade one of them for a lighter or something. Any other ideas would be awesome, thanks

You guys have the best picks of anyone. You just gotta be fast to get them... Here in rural america there is hardly anything decent for sale. And even then you still gotta be fast because people will come in and buy it immediately.

I just bought another 40' high cube shipping container this past weekend. Saw it on facebook marketplace 9 minutes after the guy posted it and started messaging him. Had to do a few things and drive an hour with cash in hand. By the time I got there he had already had 10-15 other people lined up to buy it.

Crazy shit.

It was $3000 though and looks to be a 1 tripper, and the last time I priced a wind and water tight it was $6600 right after the covid bullshit started. Who even knows what they're at now... absolute insanity.

This is literally every single Chinese product you fucking retard, and it isn’t something new, it’s been happening since the 70s.
You want cheap consumer goods, you pay a chink slave wages.

The cats out of the bag, the United States is a service country not a country filled with shitty below minimum wage factory jobs.
Jacking up cheap consumer good prices with tariffs just to prop up Stanley’s illegal immigrant filled factories isn’t fixing a damn thing.
It’s not like there are a bunch of us toolbox factories, Stanley bought them all out over the last 20 years and shit them ALL down and only has one left (which purged a lot of the old workers when they finally merged and killed the Waterloo factory)
In one fell swoop they crippled every brands toolboxes prices.
But hey, that’s the most American thing I can think of, lobbying and using bullshit legislation to kneecap competition because you are the biggest baddest tool company who has money to through at politicians.

>>2386688
Yeah, the craftsman boxes of the same size with thinner steel and shittier hardware (and a worse cheaper layout) already costs 600$
The US General even after it’s inflated price is a better product, which luckily enough still goes on sale every once in a while.

i was playing with the table saws at homo despot, the dewalt fence i was able to push out of alignment just by hitting one side of it. Is it just a piece of shit? Whats a good table saw that doesnt cost $5k or weigh 700 lb?
>>
>>2386613
even on better shop saws the fences are often the achilles heel and theres a whole aftermarket in upgrade fences...most small/ jobsite saws are adequate at best.
it's pricey for a portable saw but I bit the bullet for one of these and love it...it will do most of what all but shop saws with giant outfeed and side tables will do and the portability and out of the way storage is more valuable to me. Great saw and fence built to typical bosch tolerances and quality.

>>

pretty sure the prices you see are the saw only, stand is extra...I think mine out the door was around $700 and change a couple of years ago.
The stand is very nice if you need to move it around and very solid in use, but if you don't need to move it out of the way or go to jobsites it's not critical.

Hey guys im trying to make a uhpc mix for some round tanks I'm building for my gray water system. 6 tanks at 36" diameter by 36" high. I found this video , https://m.youtube.com/watch?v=oZWcGHnjtLg, and he is making 26,000 psi concrete but im having trouble figuring out the ingredients and their ratios. I also found some instructions online , https://hiperfibersolutions.com/uhpc/ , but doesnt show resultant mpa/psi and isnt entirely clear. Does anyone have any experience with uhpc, not grc, and can give some advice on mixtures?
