Can I "test drive" machining as a job?
I love doing CAD/Solidworks design, 3D printing, I'm good with cars and tools, and I'm really interested in doing machining. I could watch Clickspring and AvE for days because it fascinates me. But how do I get into that professionally? I can't go into a shop and say, "If you give me a drawing with dimensions and a couple hours of instruction on how to use the tools, I feel confident I could do it for work." How do you get into that industry without going through a whole 2+ years of school for that?

i doubt it op, plus most places you are just babysitting a computer.
save up, buy a lathe, set up your own shop.
but really go to school. you don't need a 2 year course, you can probably find a community college course to learn the basics, see if its right for you.
There's a lot more to machining than being good with 3D stuff.
You need to understand different materials, tool geometry, tolerances, forces generated, machine ability to take the forces, speeds and feed rates, safety, ect, ect.
No one is going to give you access to a machine worth hundreds of thousands of dollars without you knowing these things.
You might be able to get something as a machine operator doing mass production.
Best way to get into it is probably some schooling and learning manual machining methods at a small job shop.

So for Christmas I'm making my friend a Berserk themed package thing and I need to make realistic blood splatter. My local Asian market sells pig blood but I'm worried about it leaving a bad smell or something. Any suggestions on how to make legitimate blood or would real blood be fine without any unpleasantness?
>>918823
i have no idea about pig blood but i think the reason you can eat beef raw is because there is no blood. if it gets blood on it you have to cook it.
i don't know if that is true or if it applies to pigs
but i wouldn't like to put real blood anywhere.
smear it with your own blood so you don't catch anything then clearcoat it
>>918826
I'd prefer not to use my own blood. I don't suppose red food coloring would work?
Pig blood is pretty rife with parasites. You could use chicken blood. It's relatively safe in comparison. You can make passable fake blood with a corn starch recipe. I work in a haunted house and it's what we use for large-scale blood scenes. You'd have to google the recipe though.

How would I go about making a thermostat report a lower temperature than factory setting? Thinking maybe I could jam a tiny piece of metal in the side in the hope that it would act as a heatsink for the thermistor?
The control as pictured is just an up/down temperature setting, it isn't supposed to be taken apart and only has a dipswitch on the back to control reaction time. 2 degrees Celcius would be sufficient as I could raise the always-enforced 15C to a livable 17C and solve household arguments once and for all with a simple placebo.
>>918542
>it would act as a heatsink for the thermistor?
Heatsinks don't magically make things a different temperature.
They just accelerate the rate that something's temperature conforms to ambient.
If you turned a cpu "cooler" upside down and put an icecube on the contact plate, it would make it melt faster.
>>918542
Anyhoo, this thread has come up before.
Buy one that's exactly the same, then pair the existing controller with a new backend that does nothing, and the new controller with the existing backend.
Hide the new controller and backend.
>Hey /diy/, I am trying to build a robot that will follow me around autonomously, think R2D2 and the like. I'm thinking of using bluetooth as an interface and using my smartphone as the transmitter. A few questions: would it be possible to do this without having to use GPS? How would I go about a wireless system of logging distance and direction of movement between the two objects (the robot and the transmitter, ie my phone)? Any thoughts at all would be helpful as I'm only in the beginning phase of this project.

You should describe the scope of the project some more. Is this robot supposed to do pathing and obstacle avoidance so it can navigate to you from the other side of a building, or just drive towards you in a straight line when you're in the same open room?
I don't think bluetooth is the right technology for this. It's a pretty complicated protocol so you're going to be limited to using microcontrollers with bluetooth transciever hardware and other people's bluetooth stacks because doing...

GPS and a two-way radio datalink is probably the most straightforward approach, but I'm wondering if acoustic homing might be conducive to favorable behavior (i.e. robot follows sound of a beacon as it reflects and diffracts around corners and such).
>>918456
Op there are some Bluetooth homing devices out there you can look at
Even a few Arduino projects for car and cat tracking etc.
Once you know where it is its easy to follow it.
Tryinf to fix a Mac. How in the fuck do I loosen thus tight-ass tiny screw. They both are beginning to strip. Tips?
oh my fuck
imma reverse google image this before anything else to make sure
first use the proper screw driver
Proper, clean bit.
Tap the end of a driver with a light mallet. Quarter turn.
Remember when you tighten them back up, tighten the screw until it loosens back up, then back off a quarter turn
I want to add borders and text to a video to make something like pic related.

i need to make a video
>>918324
Do you have access to a video editing program like Premiere?
Use Photoshop, or similar alternative, and create an image with the same dimensions as the video file. Make sure the image is transparent (PNG files work well for this), and import the image to your video editing program and use it as an overlay.
PS: This could have been solved by a quick google search. http://lmgtfy.com/?q=How+to+add+an+overlay+to+a+video

What's a good way to replace those cheap plastic bending hinges with something more durable? I need it to be able to open multiple times a day without wearing out and breaking.

I need to make this elektroshock box to work.
This is I have no idea how.
Can any electritian help in identifying parts?
I need it to be safe. So no pluggin it into socket.
I was thinking about attaching some kind of hand crank dynamo to it. But I don't know where to even start.
>I need to make this elektroshock box to work.

what
>>918052
Just so it won't burn or kill anybody.
This is why I wan't to use dynamo to start it up.
Do they make a version of these that creates donut shapes instead of simply circles? Looking to turn some scrap vinyl siding into usable washers.
>>917790
They are called punches. You can get all kinds of dies for them.
Perhaps a gasket punch
>>917790
Can't you just use that size and then a bigger size?
Thermostat recently broke. Been nigger rigging it by touching the wires. I want to get one of those new wifi nest units Honeywell also has one although I believe they need an extra wire as only have a red and white. Is this so? If that's the case how to I go about hooking up a wifi unit in my house?

>>917583
Depends on your heating unit. The easiest thing would be to run a new wire with 3 conductors. I'm pretty sure all wifi thermostats require a common as the power requirements are greater and a battery isn't enough.
>>917597
>I'm pretty sure all wifi thermostats require a common
Don't believe Nest when they say you do not need a common.
My AC works fine without a common, but I needed ta common for heat.
I need to crush about 10 kilos of iron pyrite and get it into a fine powder, a little bit finer than sand. What kind of service or machine should I be looking for? I tried "rock milling" and "rock crushing", but most of these machines are too big for what I need. I tried "rock powdering" but most of my search results are for making crack cocaine instead...
I'd buy some crack OP, how much you want?

i'm building a uv lightbox for pcbs
i have the tubes, scavenged hf electric ballasts and fittings, some old greenhouse glass which i hope isn't restrictive to uva, some kitchen foil for covering the insides and enough ply to make a box.
the question i have:
is there a good way to work out the spacing of the tubes to avoid hot and cold spots?

Really, the only quick and easy way is to use an engineer with extensive knowledge of the lights you're using. The long and tedious way is to try it with the lights evenly spaced, then try to burn a test pcb with that set up. If you're not happy with it move the lights closer together and add a light or move them farther apart and subtract one.
>>917294
>some old greenhouse glass which i hope isn't restrictive to uva
The vast majority of common glass is restrictive to UVA.
I probably lost a week of my life trying toner transfer too. Then I gave it one last shot using a different printer and all of a sudden it worked beautifully. I quickly learned that the brand of printer and toner is the single largest variable in the equation.
Brother is a definite no. Most Dells seem to work well. HP tends to work too. Use the absolute cheapest photo paper you can find, the cheaper the better. Always print high quality, and if there is a special setting in the driver like 'make blacks blacker' then turn it on.
tl;dr toner transfer does...

My grandfather is trying to remove the clutch shaft from the transmission and is unable to find how. Any help would be appreciated.
you need a manual, theyre available online, look around

We did and couldn't find anything. He has already talked to a mechanic as well, but there is nobody who can come out and work on it because we live quite a ways from the city.

What issue is he having? I've did more than a couple engine and trans swaps on passenger vehicles, never touched heavy equipment but some things I know might apply.
My friend lives next street and we were wondering if it is possible to have a wireless network set up between our houses. I measured the distance, and it is roughly 195 meters (640 ft.). We thought maybe we could use 2 parabolic antennas and wi-fi, but I have no idea if it is even remotely possible. Could it work?

Yeah, I rigged one up in my last rent house (rural USA) and it worked. Lots of tweaking though.
>>917141
Yes, it is very easy to do. Just get 2 USB wifi devices, two 10 feet long USB extension cords, and 2 parabolic dishes (google "wokfi"). I use metal lamp shades like those used for heating lamps but you can something cheaper. Pic related. I don't have mine outside, they just aim at each other through several walls and it does the trick. For block walls you'll need to bounce it around them using some flat surface the signal can bounce off of. I had to do that for someone's wireless security cameras.
