Can I just stick this shit together or do I need to do anything with the cells first?
With lead acid I just stuck them together and it worked fine, but man I don't know about these lithium things.

BMS is for balancing cells in series, all the protection chips do is stop them from discharging below or charging above a certain point, with overcurrent protection.

I went with such large strips to give the pack more rigidity which helped in construction. I also may add a direct battery connection to power other things or charge the pack faster.
It's a bit better then a simple battery bank because it's also a phone, but I can also write an app that goes by the voltage and can do a lot of things like auto shutdown of external devices and alerts on level.
I went with 18650 because I wanted the most capacity possible without going retarded on weight and size.
If anyone can source some 65mm x 100mm flat packs, I would immediately order them and rebuild the pack. But all flat pack solutions I looked at were going to be more weight and less capacity.
The weight of this thing is still very much manageable and not a big deal. I'd say it's around 2-3lbs.
I'm also considering rebuilding the pack sooner than I thought because it's just a bit too square to go in a pocket well, and a can shave about 3mm by not using the battery cell holders in the construction.
The primary goal of this project is not for daily use, it's just too thick. It's more for long weekend camping, and traveling where it is usually a problem finding a charger.
It's nice to just clip this on as a single unit and the phone will be always working for about two weeks max.

It's now in my actual phone and I'm testing it with normal use. Bad day to wear my pants that don't fit right.

I meant 65 x 100 flat packs that were better then the Ncr18650b pack.
Keeping in mind the spec for it is 18mm thicc ish, 16000mah and change (not a made up chink number), and 250g weight.

BMS just stands for battery management system, AFAIK it's more general than just that.
>>
Works great so far.
Shaving off the extra 3mil is getting to be a necessity, its just a little bit too thick. Cells aren't coming in till next week though.
And I'm going to leave the round of the cells in as well. Doesn't slide in and out of the pocket easily being so squared off. Although the leather back should help that a lot when I get to that point.

Dominion did this to a town on Lake Erie like 8 years back. Someone fucked up and they sent transmission pressure gas down residential lines.. so everyone with a standing pilot that was set for 4 inches water column was suddenly getting like 50 psi... instant flamethrower. Town in Ohio was fairport harbor, the regulator froze because it wasn’t buried below the frost line like I believe they’re supposed to be and the safety failed.. something like 15 buildings caught fire. But fairport isn’t a very big place..

so while trying to get a hose off my heater core, I stupidly bent/squashed the pipe where the hose is attached via a clamp. I tried to "re-round" the pipe but I couldn't get it completely round. I imagine the hose is not making full contact with the pipe because I developed a small leak of coolant in there

Is there a way I can make that tube round again ? I can't slide the hose more inwards since there's a ring on the pipe that prevents me from doing so. I know I could get another clamp in there and hope for the best, but I want to see if I can fix the tubing first

thanks

Hey /diy/

Been a while since I gave an update. Some people here know, and as I'm sure most do not I recently got some real torn up land out in the country for cheap. Catch was, it was torn up by some loggers who didn't clean up after themselves. I've also had a lot of issues trying to get heavy machinery in there because as we all know, people are unreliable.

Well, I managed to swing an old tractor, and I broke ground today clearing the driveway and ultimately cleaning the place up. It's not exactly a bulldozer that's going to do the job in an afternoon, but it's what I've got. Good news is, I'll be able to finally do some real digging. I didn't get any pictures today. It was raining (hurricane is coming in) and I was just focused on running this crazy thing safely. I'll dump some pics I've accumulated so far. As slow as this board is, I'm sure I can document some real progress for you guys before this 404s.

glad to see it's all coming together. did you decide if/how you were gonna wall it off? I might be thinking of a different anon though.

you should plant some black walnut trees as a retirement fund for your daughter/other kids.

Architects and common folk of 4chan I need your advice.


For some fucking odd reason i have the urge to make an old ruin with a small river flowing inside it (somewhat like pic related), I have wanted to do this for years and am now starting to plan it all out.


So my plans for now is to buy some land at a beach so i can shit ton of big enough stones from the water (live in Denmark we dont have many big stones on land).

and buy alot of concrete to hold the stones together for the wall (idk the proper word so i will call it concrete).

So what do I need to do so it doesnt fall over itself? what do i need to make a propper foundation? of tools? etc. give me all the knowlagde you have.

as of now im saving money to do this so i have alot of time planning, and will do some research myself too; im fully aware this will probs fail, but i will regret if i dont atleast try.

Thanks

It would last, but likely not look authentic enough. Just interlocking the stone pieces (mortise and tenon) might be enough to keep the thing upright through earthquakes.

best bet is piles if you want to be next to water, otherwise foundations will shift over time.
next to the ocean is risky there will rarely be any decent bearing strata there, it would be worth hiring a geotechnical engineer to drill some bore holes before buying a plot to see if it's suitable.

best bet is buying a plot next to a river and pumping/diverting some your way. not sure what the legalities are in Denmark but over here you can't touch rivers. be careful for flooding though

>its not ideal solution because race conditions.

clearly you don't use arduinos. and I suppose I really meant AVRs and assembler, but even with arduino and C++ you have a loop that looks at the four pins. Even with C++ the loop will be blazingly fast compared to human response and perception, and you will NEVER have two presses within the same loop, so you can tell who pressed first.

And if you program any microcontroller at all and you have race conditions you are simply incompetent. It might be easier and smarter to use flip flops and discrete logic, but a 16 Mhz avr can do the job for a few bucks, assuming you can code your way out of a paper sack.

>>1467290
>assuming you can code
we had this exact question maybe a few months ago and someone posted example code for review that i can't remember how it worked but there was perhaps 5 or 6 instructions between testing each input separately.
personally i would have all inputs on one port and read the whole thing into memory and test it there, there is still the possibility someone pressed first will 'tie' with someone pressing second but you can avoid the second presser being bumped to first.

it's all well and good saying IT WONT HAPPEN but that's not really the point, this is a /diy/ board and while the OP might be happy with ignoring edge conditions the principle is important for other applications and we wouldn't want anyone else getting the wrong idea that this is an ok thing to do because it might come back and bite you in the dick at some point.

Look for perfect binding, OP. Its a way of glueing the pages to form the spine. Not as resistent, but a very good method. And also, I may be wrong, but I think japanese binding make the holes on the side of the pages, so it would also work. Bookbinding is a really great craft.
>>
>>1466917
Both great ideas. I might try a combination of the two if possible to make it more sturdy
>>
>>1466875
I've had success by squaring all the pages, clamping them together with several binder clips, then slightly fanning where the spine would be and carefully applying 5 minute epoxy directly to the paper. It makes a psudo-spine out of epoxy that works great. Next just add a cover.

Hey /diy/, first time installing a floor by myself, been calling some stores and been told wildly different bullshit from every store.

Have some in my house from previous owner. It’s okay, doesn’t look as nice as the other rooms but it’s not too horrible and it’s easy to clean. That said, I’ve had 2 or 3 boards shift apart the slightest bit (1/8in at most, just enough to notice), but I can scuff my foot across it and it pushes together again. I chalk that up under poor installation. The other issue is the old lady that owned the house before me was told that you can’t let water sit on it. She had a section redone after the first winter she had it because people would come in and take their shoes off and the little bit of snow that was on their shoes melted and water sat by the door and fucked up a few of the boards. Easily solved by putting in an area rug or floor runner, or boot tray by the door.

Op here, after going to the floor store i had to settle on vinyl due to how humid and dry my room gets every day.

So the other day I was making some ferric chloride for etching my signature on some of my projects. I did this by soaking rusted iron in hydrochloric acid in my shop overnight...

Today, I went in my shop and found about half of my tools covered in rust. Apparently an open container with 150 mLs of HCl indoors is enough to fuck up hundreds of dollars worth of tools.

Fml. Anyone know a good way to clean this shit up?

>pic related is a handful of tools that were affected. They were all pristine 2 days ago. Hell, the chisels are always kept oiled and they still got hit pretty bad.

I'd laugh at your foolishness, except I had almost this exact same thing happen to me.

Came back to it in the morning to find not just almost every single tool left out, but my BRAND FUCKING NEW ballscrews for my CNC router got dicked, too.

Feels bad, man. Took it off the surfaces I could be arsed to do so with naval jelly. Everything else, I just wire brushed away the loose rust.

I knew the vapors were corrosive, but I didn't know they were THAT bad. For the record, I solved the issue by having the acid-laden milk jug exhaust filtered through a jar full of sodium carbonate (washing soda).
