I've been doing all my projects involving an FPGAs with Verilog, since thats the HDL I was taught in school but the thing is I've noticed virtually every project I see online is written in VHDL,
for anyone who's had experience with both is it just a better language for DIY projects? would it be worth my time to learn VHDL and use that instead?
>>917139
Its pretty much the same thing. CompEng here, I was taught VHDL in a Digital Systems class that was messing around with FPGAs but in another class we used verilog for something and I remember its pretty much the same, don't worry about that. Use whatever.
>>917145
I still wonder why ever example projects I come across is written in VHDL
From my understanding Verilog is more popular in the US and VHDL is more popular everywhere else. I think VHDL is also more appropriate for scaling when producing ASIC, but I'm definitely no expert. The thing I hate about VHDL is that you have to change everything in about 3 or more places everytime you change something.
I need help making a mouse pad for my Dad. I've been cross stitching for my holiday pressents. I'm planning one for my dad, but I want it to be utilitarian as well. How could I best create a mouse pad with my cross stitch pattern? I've seen some cheap possibilities with sanded plastics, but I want something nice for him. Does anyone else have any /diy/ gifts they are working on?
Take a picture of completed cross-stitch and order a printed mouse pad.
The only good mouse pads are made from neoprene and have a rubberized backing.
There has to be a way to get the original in a pad. In going to get some frosted glass, or maleable thin rubber material from my hardware store. How could I make this? Glue it to some sort of backing?

Hey there, I am looking for advice on replicating these headphones, they arent much pics I could use for reference, the little parts that hold it together wont be a problem I think, finding something to do the "earbuds" is. I am thinking about looking for some cheap headphones with similar shape and size, what should I do, /diy/? This is my first time posting, so please be kind.

Googleing it litteraly gave me enough picks to plaster my house in reference pics.
So what do you mean replicating?
Do you need them to actually work? An actual part for part replica?
Or do you want to look like a Nazi tank commander for your video game boner
stroking?
This is an odd request, but I was wondering if anyone knows of or has footage of someone crafting, shaping, carving, sanding, etc. wood that doesn't speak. To be more specific, I'm looking for footage where someone is doing something involving carpentry and not talking as if it's some tutorial.
I find it incredibly relaxing to listen to it or watch it. Something like this:
https://www.youtube.com/watch?v=RjxUzmZpCn4 (2:39 - 2:47 is the best part)
No idea why it soothes me, I guess I'm just weird.

>No idea why it soothes me, I guess I'm just weird.
You're not weird anon :) Look up asmr to find more soothing videos.
It's not weird, I love watching people work that are really good at what they do. Especially carpenters. Unless they're doing something crazy like cross cutting a long plank on the table saw with their hands or leaning into a band saw too far with their fingers in line with the blade. I love working with wood for the same reason, once you figure out that math and do the setups it's smooth sailing, as long as you did the first parts right.
Try looking up build videos instead of how to build videos. Even some of the guys on YouTube who are self made instructors have videos where they just build stuff.
Some channels are entirely built upon silent videos.
First one that comes to mind is DiResta, aka Hideo "a Kojima Production" Kojima of DIY
so i want to build a hoop that small pellets can fly through.
if a pellet does go through the hoop a light / buzzer goes off as well as maybe some other processing.
what does /diy/ recommended? I know im going to need some kind of motion sensor but i had a look online and dont really know much about the subject
>>916674
lasers and laser detectors around the ring
make the loop a coil (lots of windings) and connect it to a lc oscillator. then connect that to a freq detector that has a go-high-when-detects-freq output. then drive a counter, buzzer, bell, etc.
the lc osc acts like a tuned osc that changes freq when something enters the coil.
>>916675
Sonic transducer. Or for a metal pellet, hall effect sensor

I'm looking for some instructions to build WOODEN AK47. I don't need a thing that can harm anyone. Just good looking prop to hang it under bed
>>916664
print out a 1:1 picture of the ak
stick it to a plank of wood
cut out the shape
chisel out the rest of the shapes
???
profit
>>916672
Well, I mean sth more realistic
>>916686
So add some "sand/finish/stain/paint" steps in between "chisel out the rest of the shapes" and "profit"
Did you want us to build it for you as well?
Hey /diy/, /g/ here.
I've always been a digital logic fag, so my analog skills are subpar. I could use some help with what some components of this circuit do. Here's what know:
C1 prevents reverse flow out the input
R1 biases the input
The gain potentiometer controls gain by controlling the amplification factor, preventing electrons from flowing across the cathode.
C2 and R4 do the same as C1/R1 for stage 2
4,5 heater
C3, prevents reverse flow through the circuit
C4, VR2 adjusts tone by controlling how much low-band FQ can drain to ground
VR3,...
Comment too long. Click here to view the full text.
>>916571
C1 and R1 are an input signal filter, I think high-pass to get 60Hz and DC out of there.
C2 and R4 do the same
I think C3 is a coupling between the amp circuit and the tonestack/volume control to keep the two from interfering with each other (hard to explain I'm drunk)
C4 you understand. Look at C1 and 2 the same way, just with fixed resistors.
R2 and R3 affect what voltage actually goes on the tubes. Look up a voltage divider and it'll give you a rough idea, not exactly the same, but the ballpark concept.
>>916601
Oh, C3 also keeps DC bias out of the output signal.
>>916571
> What I dont understand, is where R2/R3 come from, how those values were determined and what they really do
Look up "common emitter voltage amplifier".
How would you go about preserving skin with long hair on it?
Hypothetically I have someone's scalp with their long hair still attached. What's the best way I can make it last without damaging the hair so I could like, say wash said hair occasionally and stuff?
Would it be as simple as tanning the hide, I think that's the phrasing? I'd like to avoid chemicals in the event of damaging the hair and not being able to smell it regularly.
alot of "questionable" threads today. Yes, tan it like a normal hide

I apologize. First time visitor of this board.
mods! cia bait threads!
Why aren't there any reasonable 3d printers that have a 2ft x 2ft printing bay area (let's say a 1 ft height, just for shits and giggles).
> 3d printers are just for prototyping
Don't mean to sound like a liberal cuck, but spending a few hundred bucks on a machine for a prototype that is actual size is more up my alley then going for a 6 inch size of the model.
Anyone have experience with increasing their 3d printer bay size?
love bump
>>916552
>reasonable
If by "reasonable" you mean cheap, there are none that don't have shit accuracy and other problems. If by "reasonable" you mean decent quality then they are probably out of your price range. As you haven't told us your price range that makes is zero. Come back with more info, especially material and features you are looking for and maybe we can help you.
>>916650
I'm looking for shit tier quality with a large bay size. I see machines that are "meant to be upgraded!" but will then charge nearly a hundred dollars for a larger threaded rod.
I don't mind spending money for a 3d printer, but would prefer to spend at / under 1k for a shit quality large bay size machine.
Are the websites that print the .stl files compatible with prints of such large sizes? Anyone have experience with doing that?
hey /diy/, anyone here ever do an install of a natural gas line? I am looking at some remote property with free gas. The problem is while it already has an old trailer with a service already installed, my whole family will move to this property and they will need to tap in to the line. How would I go about sizing the main service line to the house? Potentially long runs, its an 80 acre property and the gas well is to the side. Maybe 500-700 feet. Any ideas?
bump, holy shit if it works out I will abuse the hell out of the free gas. THE HELL out of it. Looking into a stand by generator. Like a low rpm stand by generator or a listeroid. Gas fridge and freezer. gas stove, gas hot water tank (big!), gas heaters and hell, gas lights or heating a green house with ng.
>>916535
Free gas sounds too good to be true! If it is, go for it!
>>916535
free gas means you're stealing no doubt.
anyway, get the NG utility to do the work. long runs of underground pipe require special tools. also, tapping into the high pressure main before the meter requires the utility supplying the NG to shut the line down. typically one would use a poly pipe to run underground and the fittings are plastic welded. this is not /diy/
I'd like to design ( and then build ) my own tiny hipster house to store my lawnmower, rake and hose pipe in but have no clue where to begin. I have ideas like maybe using a shipping container half buried upright in the ground with the bit above ground being covered in reclaimed wood from pallets and some sort of protective window shutters that close over the windows to prevent immigrants form stealing my lawnmower but have no clue how to incorporate them into a blueprint.
I have no resources, I'm renting a town house and I don't own a lawnmower.
Help please.
>>916426
Unfortunately for you, the man lawn mower association has made it illegal to own a lawn mower if you don't have a lawn. They did this just to stop you anon. I know because I tried to do tge same thing.

>have no resources
no one can help you, maybe try /b/
Hey, I saw this picture on 9gag some time ago and I really wanna do it on my wall, any tips? Some I can, like RHCP and too fighters and Nirvana, but the other seems kinda hard, but I don't like all those bands. I know a projector could help but I don't have one
Stencils would be the way to go about this. It'd get you the crisp edges of the logos and you wouldn't have to rely on having a steady hand to paint them.
For the larger logos either use bigger stencils or several smaller stencils taped tightly together.
Spray painting it on after placing the stencils works fine.
or just use the grid method.
http://www.art-is-fun.com/grid-method/
My idea was to do the outlines with pencil and then if it's nice, use a permanent marker on it, but I'm not sure how it gets on the wall. BTW, I don't live in North America, So my walls aren't made of cardboard, they are bricks and the white cement stuff to paint on it, then the paint. I thought of using some adsive tape on the wall and then paint the outlines of it.
Hello, /diy/.
I got an old foot-powered sewing machine structure (the cast iron part) and plan to make a lathe out of it. But I'm having a problem and I can't seem to find a good solution due to my lack of knowledge in this area.
As the picture shows, one of the four table supporters is broken, and I don't have the broken part, nor any experience in welding. And as far as I read, it's kinda tricky to weld cast iron.
So, how can I fix it? Any ideas? It must be sturdy.
Wow it seems tricky...
If I understand correctly, you want to make a table and put a lathe machine on it ? Or use the old mechanism to power the lathe ?
About the supporter, all I can see is to use soldering and some piece of metal. If you want to make it even you would need to find another sewing machine.
Sorry I am not a specialist... good luck =)
You could perhaps sculpt a replacement from some other material and glue it on or something, unless you really want to have it be all cast iron.
Make a mold from one of the whole table fittings?
I dunno, just spitballing here.
>>916311
just put an extra wood slat under your base on that spot and surround it with some molding to hide. you are over thinking this
How would you fix the hole at the top to make it be able to be strung for a necklace? It chipped when I tried to clean it.
Don't even know if this is the right board and didn't see similar threads in the catalog.
from before if it matters
that looks a though one...
My first idea would be to use an epoxy resin putty. People use it to sculpt.
Would probably put a large lump over the hole mould it into shape then add a new hole before it sets.
https://www.youtube.com/watch?v=yOvoLmUUB-A
>>916280
The easiest fix is to superglue a bit of wire or paperclip across the top. Maybe smooth out the broken edges first. Always clean before you glue.
>>916286
This is the neatest solution, though I have no idea how hard it is to make the shape right. Maybe you can fill the whole gap with epoxy and then re-drill the hole.
