I just started a stationary hobby. I bought a Pilot Metropolitan fountain pen. I Also would love to buy a7 envelopes but i cant find a7 letter paper that is long enough to fold into 3 equal parts. The image posted is the image used to create a solid brass wax sealer. suggestions and images of stationary collection would be very much appreciated.
>>1033393
Im confused. Even after much googling...
So basically you want to create custom mailing envelopes??
And you need to find "a7" sheets of paper? I googled a7s size. Seems to me you need a paper slicer like one of those guillotine slicers. Because a7 is small just cut it from larger stock.
>>1033397
Maybe i should just go with a bigger size? a9? The reason why i want a7 letter paper long enough to fold into threw equal parts, a big enough sizes for writing, is because i plan to seal the paper, not the envelope, with wax. That way i can ensure the wax survives the mailing process. I also have my mail hand cancelled.

Thwre was actually a very long (though poorly funded) study on this. It was called Ireland.
And no, not for long. Add beans, longer, add milk/butter and even longer than that.
Check the gardening thread in /out/ for related info. Also /diy/ is pretty slow, no need to bump
Hey /diy/, I'm looking forward to getting a well secured safe for the nearby future. Should I get a wall safe and install with security screws, a time delayed one, or should I go with one easy to grab and pick, but with fire protection? I need something good to keep unique things in securely as I need to relocate things from a unsecured method to a secure one. Can /diy/ makers give good security advice?
Pic unrelated.
It really depends on what you're trying to keep safe anon. I install close to 700 safes a year for businesses and a few home clients. Typically you just need to have an audible alarm and a way to keep the thief busy long enough they give up and run.
A good team of smash and grabbers can break into a place, and break into a safe and be gone in less than 4 minutes. Keep them there longer, with an alarm going off for the building, and they usually spook. Avoid safes that have two well pronunced hinges on the outside. Many older brinks safes have that. And they take less than a minute to open with a grinder. Piano hinges are where it's at. Also, internal hinges when possible, but that's more expensive.
Time delay safes are okay, and mainly what I install for businesses. It leads back to the whole keeping robbers there until they spook. Most people are going to have a fireproof safe for their important documents, not so much for money.
I have some questions about a propane burner I've been building. I have a setup for a propane burner that reads about 30 PSI when closed, and I think a little bit under 10 PSI when it's closed. But when I open it and try to light it, the propane blows out the flame. My guess is that there's too much propane and not enough oxygen. The setup works at 20 PSI or so, but goes out if I point it into an enclosed space like the inside of my furnace. I was thinking about using a hairdryer to add extra oxygen, but what is the best thing to do in this situation?
>>1033234
Sorry anon. Not a lot pf experience with propane but I hear this works well with it. I have my own modified version for a medium sized foundry. I have burned used motor oil, gasoline, and diesle from it so far.
I think you can build a cheaper natural gas or propane burner.
In any case gl op!
kwiky burner search on google
Op you gotta get a little clearer here for us to help. Can you draw a diagram of your set up? I think additional air from a plow dryer would help if you added it to the propane stream
Just add a hole behind the flame (don't really know how to describe that, I'd need to see your torch). Flame fill create something like wind, that'll suck more air inside of the torch.
I know this is kind of a strange question, but does anyone know where to get the component used in the 3DS for the circle pad, or something similar? Just for fun I am playing creating an input method that cannot be keylogged and that faux-joystiq has both the sensitivity that I would need and a nice low profile.

Is there a way to get certifications in a certain trade without spending two years in school, I already know the shit I just want to take a test and get it certified
You don't need a pre apprenticeship course. You need to get an apprenticeahip, though. Many smaller companies would rather take a person with a decent amount of experience in construction than a kid that got out of school.
Around here, during apprenticeship you do have to go to school for 2 months out of the year until your apprenticeship is completed (4 years on a 40 hr work week). It's bullshit as you don't learn jack shit and have to pay for it. It's a cash gtab.
>>1033174
Depends what it is.. You can actually become a master in a trade by just doing it and having experience and a good portfolio.. Most trade papers just say "you studied under so and so, for 2 years and they are writting off you have learned enough."

Hey dudes, I was planning to make a micro-grill. I was gonna take a metal box o cookies pic related, and take bamboo barbecue skewers wrapped in foil and poke it through the box to form a grill. Only problem i've seen is that apparently foil is unhealthy. any alternatives i could use to make a grill?
plz be gentle, first post on this board
>>1033158
You don't sound old enough to be playing with fire.
Get off your dads computer and go take a nap.
Pretty sure any plant based material won't last more than 30 seconds under a flame. Wrapping it in foil will only create charcoal (I think). Get yourself some stainless skewers or something like that. The paint and other coatings on the tin wouldn't be very healthy to breathe when they melt as well.
All around bad idea but an ideas still an idea so go for gold. As long as you don't die you'll learn a valuable lesson.
>>1033476
not really gonna use it as an actual grill, more like a novelty, like " hey guys, check out what I built! A tiny grill!"
Hi everyone,
I'm currently trying to control a load (requires 12V and something like 1 amp) with the logical output of my Arduino Uno (0-5 V, probably a few hundreds milliamps.). The emitter power supply delivers 12V at up to 1.5 amp.
So I have a few questions.
1) I guess my transistor must have a max. collector current above 1 amp (maybe more, to be sure) ?
2) This collector current must absolutely be limited by a resistor, right? But the voltage and current limits make it so that the resistor would be reaaaally low. Is there a solution? No resistor?
3) Have you got an idea as to which transistor i should use, and what schematic i should apply ?
thanks for reading !
>>1033005
There are a couple of different types of transistor configurations, and the difference between them is how much current you will need on the base to activate the switch. In a typical transistor, the amount of current needed to put it in saturation mode depends on how much load you are switching. Since you are using an arduino, I would recommend a darlington transistor because you can only apply 40mA of current from any output pin. Use something like a TIP120 or TIP122.
As far as current limiting the load, you're right that if you use a resistor to limit it, it will end up being only a few ohms and will dissipate a lot of heat, which is wasteful. Your better bet is to use a power supply that is already limited to something close to the current that you want, or to add a second device to your first device, in parallel, to split the current between them. It's a tricky question and one that may have no "good" way of doing it.
>>1033011
Thanks for the quick answer !
A TIP120 has a max collector current of 5amp, and my power supply won't go over 1.5 amp (which is alright for the load). Does this mean that i don't have to use any resistor in my circuit? Like logic output goes to base, power supply Vcc+ goes to Emitter, load between ground and collector?
>>1033011
Also, depending on what it is that you are powering, the load itself may be able to limit the current. That is, the load may only draw as much as it needs, so no additional current limiting would be necessary.
I think TIP120 is rated for something like 10A, so you shouldn't have any problems overloading that device (just be sure to put a heatsink on it), so as long as your device doesn't instantly self destruct when you apply the power supply to it without a switch in the middle, it should do fine when you apply power with a switch in the middle too.
I'm sure Google has some schematics for wiring up a transistor switch to an arduino, so check there if you need a wiring diagram.
>bought a house a year ago

>decent HVAC performance
>didn't renew the policy
>decided to check the system though
it was cooling but not as much as I wanted
>low refrigerant, small leak in the evaporator (small enough that I'm losing about 1-2 lbs a year, at least that's what I calculated)

A new evaporator is like $4000, the warranty is like 500 a year with something like 1000 deductible (I still have to check though to make sure).
When should I restart the warranty to avoid any "pre-planning suspicions"?
According to my calculations, it will take at least a year maybe two to lose enough refrigerant that will allow me to pretend that I just noticed a problem with it.
Will they do any research with local companies to see that I had it recharged recently?
>>1032986
I'd just pay for it now and have them fix it in a month or two before it gets worse.
>>1033358
OP here.
The system will run fine until at least next summer (unless something happens to the hole to make it bigger) or, worst case scenario, end of summer (there's not much hot season left).
I'll probably start the warranty in September-October to make it less obvious I'm concerned about the AC. Fuck it, if anything else breaks in the house I can fix it myself but I don't want to touch refrigerant systems.
I wonder if there are warranties out there just for the AC part of the HVAC ...
>>1033488
Sometimes a home warranty needs additional options to cover an AC.
When I renewed a warranty after I allowed it to lapse they didn't require a reinspection.
You help me, glory for the Chinese to do this. American mc burger!
Then do it.
And ask for help when you get stuck.

Custom controller help needed.
My brother recently had an operation to remove a tumor from his brain which they managed to remove successfully but they also had to scrape dangerously close to his spinal cord, because of this he now has very limited use of his right arm and leg and lost most of sight in right eye but he is walking again with crutches.
Anyway, enough of the sob story, I would like to make him a custom controller for xbox 1(or ps4/pc) Ben heck has stopped selling his one handed controllers and I think they were very expensive anyway.
I'm thinking of something that will make use of his feet for buttons and thumbstick/s for left hand. Point is I need some help in right direction to get some ideas, my electronic skills are too basic to pull this off by myself. He loved gaming but unable to do so now, he can't go back to work yet if at all so he's just doing physio or stuck at home all day. I'm determined to make something for him, really don't care how it looks just as long as it works. Where do I start?
>>1032573
Please and thank you, my bad.
This is a good thing you're doing, OP.
I'd start by buying 2-3 controllers and taking one apart. Check how everything fits together and which wires go where. Then, just create the input system you want (if XYBA will be his foot, then four switches) and link it to the place where the thing you're replacing goes (wire from the foot switches to the PCB or whatever, i know nothing about xbox controllers)
You'll probably need to do some soldering. The extra controllers will be useful for parts. Other than that, ask specific questions in electronics threads
what about a DDR pad?
So i recently made my own Ikea Kallax look a like shelf out of some spare wood, would it be possible to paint it in the true Ikea Kallax color without people noticing any difference in color between my home made shelf and Ikea shelf if they are standing next to each other?

not unless they are blind

I want diy my own platform bed frame. How should I go about making this? Retail is $1200 and I think I can make one fore under $200. Pic related.
>>1032266
i know someone that has one...the slats in the middle are just 2x4's and there is a support beam int he very middle the rest on along with the sides.....very easy design
>>1032277
sorry, new laptop. there is a support beam in the very middle and the slats rest on that and on the sides
>>1032266
Go and visit the actual bed in the show room and see how it is held together.
Deconstruct it on paper.
Then replace all the knockdown fittings (as I imagine it's flat pack) with real joints.
Hey /diy/
I'm trying to machine a shot glass out of 20mm shell casing. My questions are thusly
>Will alcohol affect the metal
>Is there a coating, resistant to alcohol, that I can use on it
>Is this even a good idea?
>>1032239
It's a great idea, use something called bisphenol a to cote it. It's the same stuff they coat aluminum cans and canned foods with.
>>1032239
>>Will alcohol affect the metal
No, the casing is brass. A couple washes with soapy water and alcohol will get rid of any lead/combustion residues still lurking around. Pretty much any cleaner that doesn't have ammonia will do.
>>Is there a coating, resistant to alcohol, that I can use on it
Something that isnt't water- or ethanol- soluble. Only thing I can think of off the top of my head is teflon, but that shits too complicated to coat with at home. Just make sure whatever you use, you seal the bottom where the primer comes thru
>>Is this even a good idea?
>Asking this question on /diy/
go get turnt my fegit
>>1032239
You could place a glass shot glass inside it, that way you get the look and it's safe to use.
These are called Chicken Bump Feeders.
Its a trigger that a chicken pecks at and it bumps the feed to allow it to fall down so he can eat it.
I want to brainstorm on some idea's on how to DIY a few of these.
Usually you just take a bucket and put a hole in the bottom then you put the trigger end through the hole and fill the bucket up with feed.
The cross part holds the trigger in place and the paddle on top stirs the feed.
Then when the chicken hits the trigger at the bottom each time the food gets stirred and some drops out the hole.
