Welcome to /diy/, a place to:

Post and discuss /diy/ projects, ask questions regarding /diy/ topics and exchange ideas and techniques.

Please keep in mind:
- This is a SFW board. No fleshlights or other sex toys.
- No weapons. That goes to /k/ - Weapons. The workmanship and techniques involved in creating objects which could be used as weapons or the portion of a weapons project that involves them (e.g., forging steel for a blade, machining for gunsmithing, what epoxy can I use to fix my bow) may be discussed in /diy/, but discussing weapon-specific techniques/designs or the actual use of weapons is disallowed. Things such as fixed blade knives or axes are considered tools, things such as swords, guns or explosives are considered weapons.
- No drugs or drug paraphernalia (See Global Rule 1). If you want to discuss something that could involve such things (e.g., carving a tobacco pipe from wood) that's fine, but make sure it's /diy/ related and doesn't involve drugs or it will result in deletion/ban.

Some friendly suggestions for posting:
- First ask Google, then ask /diy/. Your question will probably be better received if you do so.
- List available resources (tools, materials, budget, time, etc.)
- Try to use pictures and explain the goal, if possible
- Be patient, this is a slow board; your thread will be around for days.
- Share your results! /diy/ loves to see problems solved and projects completed!

Okay folks, I want to make a gaming PC. According to my research, the first step is buy a CPU. I have $1,000 dollars to spend on this and I want to make this a beast of a PC. Any suggestions on what I should get?

Fallout isn't really graphically straining. Make absolutely sure you get a SSD and good proccessor. A 1070 would suit you perfectly. Don't get a 1060, it's just asking too much of too little, and your build won't last as long. I would really suggest finding a nice cheap 1080, even the base ones run well and have aftermarket cooling you can change out later. Even if you only play fallout, you'll regret it when Fallout 5: Hawaii comes out.

The NSPW500BS is specified to about 3.5V at 18mA which is 14V for four in series. With a 24V supply you could drive six LEDs per branch instead of four or increase the value of R8 .. R11 to 330Ω. The current value of 2.7Ω doesn't make sense in any case.

The circuit was originally meant to stabilize the LED current over a wide range of supply voltage. If you have 24V or a bit more this is not needed. With 10V headroom a single 560Ω series resistor per branch of four LEDs would be good enough.

long story short: I have "built" an ultrasonic service for my pc/server to broadcast. I basically downloaded some digital snake oil and have a dedicated program looping the ultrasonic audio and broadcasting it to a bluetooth receiver/speakers in the kitchen while my pc and home theater audio is free from that noise. I feel accomplished; however, the signal is choppy, and although that may or may not affect the purpose of the stream, I'd rather it be as clean as possible. What can I build to boost the signal of the usb dongle I have emitting bluetooth signal from the top of my full atx tower. It is maybe 4' off the ground. I'd like to have something I can solder a female usb port to and have the adapter connect and have the signal boosted with circuitry added to the board, but I assume I may have to solder directly to the BT dongle.

If I have to buy an amplifier, so be it.

I'll post pics later and maybe we can determine the location of the antenna.

If there is a better route, please let me know.
>>
>>1283596
shit never mind, I see the antenna.

I forgot to ask this earlier. What happens if I don't fully remove the original antenna from the chip? what if I just pic a spot on the trace/antenna and solder a 3cm copper antenna to it? will that duplicate the signal, or just fuck with the signal strength, or will it follow the path of least resistance and utilize the thicker copper wire/antenna?

I guess I have commitment issues.
>>
>>1283596
Well holy fuck, it works. It looks like shit, as I used 3cm of aluminum foil and blue painters tape to connect it instead of solder, but I can hear solid audio from the kitchen now. I made the antenna in the shape of a rectangle, 3cm long x the width of the trace/antenna on the chip. Itaped the base over the antenna and bent the remainder somewhat vertically to throw out the signal and it works. ASt first the receiver blooped at me, but I power cycled it and now I am getting stutter free ultrasonic audio from the kitchen to hopefully keep pests out.

The dogs don't seem to mind too much, even though I don't want them in the kitchen either, but can other animals be tormented by these frequencies? Specifically reptiles, amphibians, and even fish. I have a turtle and a toad that cannot bark like the dogs can when shit gets weird, and i don't want to torture them. I'm assuming the fish won't be bothered, but I don't know yet. After posting this I may either google more for an answer, or maybe finally get some sleep to the sounds of my new pest repellent broadcast.

P.S. if anyone gives a fuck I'll post pics.

P.P.S. Happy thanksgiving.

I'll be throwing images in a report doc of the whole thing sometime, considering what the board is. It's part abomination with a maw at the pouring end. It's as soft, if not softer than what it originally was. The wall thickness of the old item was about 30mm, no reduced to 25 so any change in perceived material property may be due to original product design. The next iteration is even thinner to compensate for cooling issues in the center of the mold, where the tentacles would be.

As for tight, having removed the mold and allowing the material to expand results in a natural expansion, so it's not tight at all. Soft shell mounting had little effect.

Now I'm thinking of glass fiber reinforced casts...

That's a CNC setup, it's going to be slow as christmas if you try to use it as a 3D printer. Geared NEMA23s and ballscrew axes make a lot of sense if you need a whole bunch of torque for cutting metals, but on a 3D printer it's useless and just going to get in the way.

Is it possible to clean and butcher a deer in a bathtub?


I hit a deer in my work truck earlier. There was no damage to the truck because it has a brushguard so I just put it in my truck and finished going home.

I live in a apartment and I've never cleaned or butchered an animal before. Think I could do all that in my bathtub or is that too messy? I don't want to get blood everywhere but at the same time I don't want to waste all that meat.
>>
>>1283586
Skin it first, a bathtub would get messy and filled really quick and youd need good air conditioning or just do it outside
But honestly give it to your local butcher or someone with experience. If hes a nice guy he'll keep his mouth shut and you share the meat

I have a sick fish that I need to put out of it's misery. Most forums recommend either freezing the fish or mixing clove oil in the water to kill the fish humanely. I don't have clove oil neither do I plan on freezing the fish since it doesn't seem very humane.

To be fair when you adjust for scale killing a mosquito with brutal crushing force is probably more humane that those fuckers deserve..
>>
Bigger electrodes (e.g. two metal pans) will get you more current through the water (more likely to kill the fish) but you'd also be more likely to trip the breaker. I have no idea how much current it takes to kill a fish, though. Usually 230V shocks don't kill people, but this is through a tank of water, so there will be a lot more current than if a person just touched some wires. Electrocution is not the first thing that would come to my mind if I were trying to kill something humanely. They use electricity to humanely slaughter animals
https://www.hsa.org.uk/electrical-stunning/electrocution
but apparently it's not so simple; they have to do a nonlethal jolt to the brain first, or else the animal will feel pain. Seems very likely to cause the fish pain, perhaps without killing it.

>>1283243
>Electrocution wont work because electricity takes the path of least resistance, which is not by going through a fish.
Not how it works, electricity takes all paths, in inverse proportion to their resistance.

Only if they can prove that you removed the boot. It doesn’t matter that they have a log connecting your car with that boot. You never saw a boot, don’t know anything about it. Meanwhile, they don’t have a damaged boot to enter into evidence because whoever removed the boot from your car must have dropped it off of a bridge. Or maybe tossed it into one of those streetcorner burn barrels that bums gather around to stay warm.
>>
>>1276799
Ok how about this:

We live in a free capitalist economy right ?
So we need a new law and a new service.

The new law is:
A boot which prevents the wheel from being removed is illegal to use. Once the wheel is removed the boot can be easily removed.

The new service is:
A company that will stop by and change your wheel for $35, much cheaper than the $150 boot fee.

The company or individual leaves the boot lying in the parking spot for the business owner/ city to collect .

This is more than enough deterrence for illegal parking and will not result in these excessive bills to get out of the mess.

Made pic related (small shelf brackets). Turned out okay.

I used a table saw to cut the slots, but the joints weren't as tight as I would like as the saw cannot make tight corners. I tried to clean them up with a chisel, but it didn't help a lot due to the small size.

If I make more I'm thinking a hand saw with a miter box would be better. Make relief cuts and then knock out the chunks with a chisel.

Any other ideas?

You need to get to know your cheap tools; My drop saw is about 1 degree out when it is on it's "center" indent, likewise my jigsaw, and the belt on the belt sander wanders everywhere if you go at it too hard. You compensate, and you get a good job done. I am not a tradie, but all this shit gets used at least monthly and for the money I'm very happy with my chinesium workshop. Don't be afraid to buy cheap to begin with, and if you find something is just not cutting it (kek) by all means, buy the premium badge.

My old boss just bought an AEG kit because he's only got 5 years left before retirement and the impact driver died in about 2 months but the drills still going hard.
