A zip gun is a D.I.Y home made Gun that you can make from old wide Ford antennas. Hoodlums in the 1970s used to make them all the time.

Well /g/ is useless. I was hoping for some advice on HVAC stuff. I was planned on getting a 1/2 HP Aquarium Chiller and probably a 350 GPH pump for a pc cooling loop. I was going to install it in the attic and run it to the room just underneath. Are there standard control panels for these that I can mount in the room with the pc, or in order to control the pump at the same time should I get something like a swimming pool control panel? How careful will I need to be about condensation? I'm in the tristate area. I figured if I just insulate the tubes and don't get too far below the dew point, I shouldn't have much trouble. Am I being too optimistic? Should I get an airtight case with a humidity sensor? Am I just going to ruin my ceiling with water stains?

anyway, the thermal mass will carry you a ways if it's big enough, but you probably don't want it upstairs. A sump pump will pump water straight up a good distance. If you don't want a swimming pool full of water you should probably have a radiator and a fan.

Hey guys so I'm having a problem with my laptop that I can't seem to figure out.I recently changed the bottom cover of my Alienware m9700 and after I did and put everything back my keyboard and CD drive started acting up.My keyboard won't type and my CD drive won't read.I was having problems even booting well the keyboard was attached,so I was wondering if anyone has ever come across this problem.If so how did you go about fixing it?

Why don't you try and see if that fixes your problem first?

Visual inspection first.
Then disconnect parts one by one to isolate the faulty part. Replace with known good part and see if the problem persists.
Troubleshooting PC hardware over the internet is really tedious so please try and see if the problem is fixed by carefully reasembling the laptop.

I'm building a dog enclosure using woven wire stretched and attached to 4x4 cedar posts at corners. The corners are connected by horizontal 4x4 cross braces.

The problem is the grade varies along the fenceline. Do I just attached the woven wire the top of the posts and match the grade at ground level or should I make cuts instead?

So far the fence is stretching nicely. I have a big incline to tackle, so I expect some hovering. One method I read about is kinking the cloth along one vertical strand to make abrupt angle changes.

My personal most used tool is the toothpick, followed closely by scissors.

30 year old boomer here. I've been carrying a skeletool cx around clipped to the inside of my back pocket for close to ten years. It's pretty fucking convenient. A lot of the tards itt think a multitool is somehow a tool replacement, it's not. It's something you have on you to use really quickly when you can't get another tool, or getting another tool would be a pain in the ass. It's for when you notice the screws are backing out on something so you fix it in ten seconds rather than putting it off and forgetting about it. It's for when you're doing a simple electrical job and you realize you need to do a three wire splice and you only have one pair of lineman's. It's for when a buddy is sitting there looking like a retard trying to open something, and you say "I got this". It's for when you're sitting around a fire and someone brings out a few beers, but no opener.
Often it works really well for simple crap. I've got a good eye for knowing if I can do it with the multitool or not. Early on, I'd sit there struggling with it trying to do something it can't accomplish. Don't do that. The proper tool makes all the difference. The multitool is for when you're caught with your pants around your ankles, dick in hand, going "aw fuck, I don't have the [whatever tool], but I can cheat it".
I also carry around a ZebraLight sc62w, and it gets more use than the skeletool by a factor of two. If you don't have a good pocket light, get one.
>>

>30 year old boomer
Wut.
>>
>>1632174
Nah, the single pair of lineman's gets me 70% of the way. The skeletool pliers get me an additional 20%. For everything else, there's channellocks. But fuck if I'm going to bust those out every time. They're basically reserved for 10ga work and under.

I want to start a DIY project where I can apply some programming knowledge (mostly python) and somehow relate it to astronomy. I'm looking for project ideas - right now I'm picking up programming again and studying astronomical navigation, so I'd like to combine these two areas. I'm mostly interested in programming automated systems, and one of my pipe dreams is to make an automated self-steering system for a small sailboat. I don't have any experience with arduinos or raspberry pi's or whatever though, so any books or guides would be appreciated. Thanks

Automated celestial navigation for boats? Half the task is actually getting a star/sun sight, the other half is pure chartwork. This guy gives a good primer https://youtu.be/v2tdodFoXz8
The math behind it is spherical trigonometry which isn't too bad, but it can be simplified using lookup tables like Norie's. https://www.southbankmarine.com/product/nories-nautical-tables/

As for accuracy, a sextant can read an angle to 1 second of 1 degree. However there is a lot of guesswork and art behind getting an accurate horizon to celestial object angle on a rolling/pitching boat.

- simulated "figure out where I am" system based on celestial nav, for a hypothetical FTL ship (pop out of warp, located pulsars, triangulate)

How about you fuck off and stop telling people everything is out to kill them?

A pair of glasses if you think what you're about to do might suck is all you need. If sparks and tiny chunks of metal hitting his wrist starts to bother op I'm sure he's got the mental capacity to figure out how to stop it from happening. He's not gonna fuck himself up by not wearing long sleeves period. This also wouldn't annoy me so much if it didn't seem like this whole board is just osha coming together with nobody actually doing anything, just talking about the safest way to do it.

a knuckle is not a spindle, a spindle is not a hub. a hub is not a knuckle

a spindle is a fixed straight shaft. solid.

a hub is the piece with a hole in the middle, with a bearing usually, that goes over a spindle

this assembly is sometimes, but not always, mounted to a knuckle to allow it to pivot. sometimes the spindle and knuckle are one solid piece. in this case its still called a spindle and a knuckle, or the knuckle's spindle

if the spindle is fixed solid and cannot move in anyway, there is no knuckle. a knuckle has to be able to move to be called a knuckle

Hope you're having a nice sunday, /diy/

I'd been wanting to build a small lathe, and had been trouble coming up with how to machine the base. After sifting through some epoxy granite stuff, I've found the Gingery lathe. On one hand casting the parts out of aluminum seems so easy and effective, on the other hand, I don't see it very often and I don't see anybody reporting on using these machines long term, so I'm wondering about the caveats. Are there any besides lower weight and thus less vibration absorption? (contact surfaces on the bed would be bolted on)

>>1631058
>Elaborate pls

Elaborate on what?
The fact that you can literally buy a chinesium lathe that will be better made and more stiff for less than the cost of raw materials for the gingery lathe?

When the book was written, there was no cheap lathes on craigslist or cheap harbor freight lathes, and scrap was cheap or free.
There is a reason that its not popular to build stuff like this, its cheaper and easier to just buy a tool which in the end will work better.

this. any homemade aluminum way is better than chinese machinery.

potentially, if the home made stuff is at least cast iron or a purchased linear rail.

honestly, it seems a bit odd to me that people are willing to buy cheap crappy dovetail way machines when they could spend the bulk of the money on quality components like linear rails and servos then afro engineer the base out of epoxy granite or aluminum or whatever.

Didn't Okuma experiment with a cheap aluminum CNC mill? Okuma's "economy" line is still pretty pricey of course.

I recently got a laser from a parts bin and would love to put it to use, but I haven't the faintest idea how to start. The barcode doesn't scan, and the part number (if it even is that) doesn't show up in any combination of spaces and dashes I put into it. I don't have any info to go off of except what's written on the label in the picture. Is anyone familiar with these, or lasers in general, so I could start identifying it? Any help would be appreciated. I don't want to simply power it and see what happens, and I'm not planning on just sticking a power supply on this and pointing it at things or people; I know the dangers of blinding/burning/etc. that come with lasers.

Failing that, general laser thread, I don't think I've seen one.

Eye protection is most important. Just the reflection of the beam off a distant object like a door handle and back into your eye can cause eye damage.
>>
>>1631183
>>1630990
In terms of H&S the most important thing there is the class IIIb designation, so absolutely be concerned about eye damage (look it up). With the right enclosure you can consider it a class I laser (in other words build a test enclosure).

The barcode might scan if you retouch it so the black parts are solidly black again. It's pretty badly damaged
>>
>>1630990
That's a class 3b laser, which is a part of the safety classifications. When you run current through that sucker, wear eye protection. Class 3b is a fucking big range though, anywhere from 5 to 500mW. Gonna say that's relatively on the low end just based on its apparent size. Wish it said the actual wavelength on there, instead of "wavelength" with a blank space. I'd hazard a guess that this shines blue, given that looking up "b150 laser" gives replacement lasers for blu-rays.
>>
Unfortunately, the fact that it's a 3b laser is the most I've been able to figure out myself. I asked the guy I got it from, and he said it was also a hand-me-down that he never got around to using, so no luck on that front. I'll try retouching the barcode and see if that works.
