Hi, I don't come to /diy/ often, but I have come to a dead end and I desperately need some help.
I have a pool very similar to this and the inflatable ring at the top gets very small punctures every now and again causing it to deflate. I've tried using FlexSeal all over the ENTIRE thing, but all that did was make a mess and to be honest, that shit SUCKS and never dries properly even after a week.
So I'm thinking I can get a nice canned latex/plastic kind of paint to brush over the entire thing neatly.
The goal is to sort of fortify the plastic ring so it isn't so easy to puncture.
I've been to HomeDepot and ACE, to no avail.
I would prefer it to be blue, but it's getting desperate.
Thankyou for your time.

Tape the whole thing with duct tape like myth busters, then paint it with whatever for the color?
>>1081058
Thanks.
I thought about doing that as a last resort since that would take mountains of tape being properly placed. That's why I thought a nice coating of paint might be easier.
>>1081055
find a (commercial) tent maker in your near, get strip(s) pvc from them, glue layer of that on top, done. Pool liner (garden store) would also work, thats usually bit heavier material and (normally) only black tho. But I dont see how paint (latex, or otherwise) is gonna work, if that is ever deflated/reinflated, which it presumably is on ocassion.
Cut out some circles for a sharpening wheel. Going to glue them up tonight and smooth it out after getting it on the bench grinder tomorrow.

>to avoid injury with a power tool you have to put your guard down
>>1080709
well it didn't work great
the wheel was fine, but without some kind of gauge it is going to be terribly inaccurate
(it worked great for leather smoothing though)
a leather one will be next
finished the handles finally, might make them again with a different species just for fun
Hi guys, wanted to ask if anyone here knows what are the best materials to use for watercolor paper. Any info&tips on how to do it would be appreciated too. My daughter went to art academy so I want to cut her expenses by making her some paper for watercoloring
Aquarelle paper is cheap as fuck when you buy it in bulk.
If you are too poor to afford an artist in the family than you should of thought about the cost of a useless leach on society before you let her go to college to learn how to be a lazy procrastinating slob for the rest of her life.
It's going to cost you a lot more money to make decent quality paper than to buy a 25kg roll off a suppler and than just cut it to size.
If your heart is set on it. You are gonna need some fine ass Swedish timber and an axe.
Chop down a tree strip its bark away and than dry it over a few cold windy winters.
How chip said timber in to small chunks and wash them.
Turn them in to smaller chunks via grinding stones or a rocks and your trusty wooden axe.
How cook your chunks untill you get a fine looking smooth paste of wood, and water. Change the water and add bleach. You can find bleach salts at a pool supply store to save on money.
When the paste becomes white enough for your daughter not consider dating it you boil off the water and let it dry.
When its at around 5% moisture its ready to be pressed in to sheets of paper. Determining the thickness of the sheets and the pressure setting of the press depends on your equipment and desired results.
Roll your paper in to large spools and cut spools to size.

Except we want rag paper...

yup
My cabins bedroom have no airvents, windows and it tends to get really cold during autumn and winter.
(Northern Sweden)
I have a portable heater.. Which only makes the air above (50-100cm) warm.
So the beds and floor remain cold.
To make the beds warm I had to elevate a pylon fan behind the heater.
It looks like utter shit and takes a lot of space.
That's were I had this idea, to make a ventilation that has a heater behind a fan.
But I'm concerned about fire safety and effectivity.
The air will be sucked from the kitchen which has good airflow and an airpump.
The wall is around 20-35cm (standard plywood and isolation).
I hope to make it so I can retain the revolving ability of the fan so the air can be divided equally.
I have tools, done a lot of diy projects, some electrical and carpentry knowledge.
Please /diy/ point me in the right direction .
Köp billiga chassi-fläktar(från datorer) och sätt på längst uppe med skruvar/Zipties(antar att du har en sådan som är längst upp till höger på din bild). Koppla sedan till 12volt, kanske finns inuti elementet.
Use exhaust pipe that's made for a dryer, it's made to have high heat flow through it
>>1080194
Thought about using chassi fans before but it wouldn't be effective enough and the hassle, compared to stripping a pylon fan seems to big.
>>1080197
Hm that's not bad, do you know what material it is? Then I could insulate the inside with it, sense I want it to be at least 40-50cm wide. Sorry for not specifying it before.
I'd like to build a shake charger like this to charge a 12v battery, but how do I design it so it's the right voltage and so it won't over-charge?
Wow
Do you realize how awful that will be? Do you mean a 12V car battery?
Voltage is based off of the number of windings but just fyi that will take something like 600+ hours to charge up with normal shaking
>>1079192
So what would be a better way to get power from a reciprocating motion?
>>1079180
1. Learn how to design DC-DC converters (buck, boost, buck-boost, SEPIC, Cuk, etc).
2. Learn how to design a battery charger for the specific type of battery you want to charge.
3. Figure out the parameters for optimum power transfer (or use MPPT).
BTW, the "shake" mechanism sucks. You'll get much better efficiency if you mechanically convert the shaking motion to rotation then use a rotational generator (i.e. a motor).

>turn on machine

How is it possible to power these machines?
Do they have a power plant on site to feed these furnaces?
How can the local power utility divert resources to the furnace on demand like this?
What do the power cables to a steel factory look like?
They have dedicated industrial lines from the plants sized correctly, no mystery to it.
Also power cables aren't as big as you think they would be, industrial lines are typically 214kV or even higher
>>1072708
Higher voltage=smaller cable to deliver more power
So I figure, if I run my ppg through a primary circuit breaker THEN ran city power through a secondary breaker that ONLY is connected to, say, my porch light, then would I be breaking any laws? The city would get monies and I would have my own power. Pic so unrelated.
>>1082201
I believe you to be operating under that false premise that you have to buy poco (power company) power. Please provide your city/state if you believe this to be true.
As for your question; your terminology is garbled. You'd run your "ppg" (i'm guessing this is some alternative power source) to your main load center and then have a secondary load center attached to your poco meter and a single circuit coming from it to a dummy load that would spin the meter a bit. There are no primary or secondary breakers in a panel. They all attach to the same rails.
Panama city Florida. Also using a magnetized rod with ferro fluid coated bearings I think I have found a way to reduce friction to null levels. I know there are news stories about ppl being fined and charged with crimes for not being on grid.
>>1082231
Don't worry about the power company, but breaking the laws of thermodynamics means that spontaneous combustion is not far behind.
Dear DIY,
it seems everytime i try the ez methods like the one shown it never works, can someone tell me easy way that is 100% effective for an idiot like me to do?

Hey guys
So I tried to etch something today, but It came out wrong because I used the wrong gloss paper for it. Now it just looks rough, and I want to redo it with a better design I drew in Photoshop after seeing this one was fuckin Garbo. Is there any way I can reuse this housing?
Did you use mechanical or electro-chemical etching?
If its not too deep or hardened steel, just resurface it
>>1081866
It's aluminum, and I used ferric chloride.
How so I go about resurfacing it?
>>1081868
Get a dead flat surface or sheet of glass, wet-sand it from about 600 through to 1000 grit
Thing I found with aluminium is that you do want it very smooth to work well with stuff like etching, anodising and the like- basically polish it near-mirror or as close too as you can
Hello /diy/
I'm super broke and my laptop's connection to the power inlet thing separated. (See picture)
I've tried to solder it tgt, as you can see from the melted plastic mess...and I had success with soldering the wires (3 different ones) tgt but can't solder it to the connection tab (?) The solder forms little beads that just fall off and don't join the connection. I'm brand new to this and don't know what I'm doing. Any tips? Reason why its not working? Thank you
>>1081774
Did you use flux?
>>1081786
No? It's a rosin core solder do I need to?
>>1081774
I dont know if youll manage to solder that. I think the previous anon might be right about needing flux for this. soldering wire is easy because the twisted wires have cavities for the solder to flow into but that tab has nothing. the flux might help with that but Im not sure. If it were me (and im pretty dumb) id try to mechanically bond it some how.
I bought this clock online and it said it would work with a "small watch battery" The hole in the back is 6mm deep x17mm diameter. Could anyone help with what kind of battery I need? will this even work? I don't see anything inside that the battery would even contact. But I don't know much about these things... please help me.
>>1081634
take a straight on photo of the hole and under strong lighting
put a ruler next to it
here you go

this fucking retard you have to block the inside do you so nobody can see shit
How do I go about removing the epoxy/clue that someone probably used to affix this soapstone? I'd like to use it for either a kitchen cart or coffee table project, the current stand is hideous
>>1081538
glue*
>>1081538
do you have gravel in your yard somewhere? the neat thing about soapstone is it's a fairly hard material so its hard to scratch, but that means you can use equally hard materials such as other rocks or porcelain to grind it. just drag it out onto some gravel surface and skate around on it, it'll grind the soft epoxy right off, the alternative is to do it chemically, but that may spoil the surface even more by letting the epoxy soak into it.

how would I go about shaving a bit of the rubber off for better connections?
>>1081449
You're fucking kidding right?
>>1081452
no.
connecting very, very small wires to a small circuit is hard.
>>1081449
What am I looking at, OP?
So I have a small keyboard that was made as an external keyboard for a PDA, and I need it to connect to a raspi somehow (USB/other serial signal). It's a "Folding iPaq Keyboard G750", and opening it up reveals that it has VCC, GND, and data connections. USB has two data lines, positive and negative, but would it potentially be possible to send a single data line through it? It'd be through the positive line, I'd assume?
USB is a complicated business, and the PDA is old, so it likely doesnt speak USB. much more likely it's proprietary, or it could be PS2, tho it requires an extra line for a clock.
>>1080741
>>1080729
It's not USB. I used to have one of those HP Ipaqs. They're USB slave only. They can be connected to a PC through USB but you can't connect keyboards, mice,etc to them through USB.
The cradle connector also had an RS232 port which must be what your keyboard goes through. You should be able to connect it to the RPI through it's UART. I'm pretty sure it was full 12v RS232, so you'll need a MAX232 chip and a few capacitors to level shift to TTL RS232.
>>1080741
This is the connection, it has a single data line. The one I have doesn't have those components, it instead has two melf diodes.
I really want to try stick and poke, Im on a small island in greece for the next 3 months and have nothing better to do. I already have 1 mechanical tattoo but i want more. I'm familiar with most of the needed materials. Does anyone have any tips or experiences with Stick and Poke? Being on a small island, i can only use Higgins drawing ink, a regular sewing needle. I saw that most legit stick and poke needles have 2-6 needles at the end. could i bundle more needles?
>>1080171
Multiple needles are good for thicker lines and filling in. Pretty much not matter what you do, it'll take several session to do anything.
>>1080205
is it normal to bundle the needles? also i plan on using an orange for practice
Is using drawing ink safe ?
