Get a better table (used),
Adjust tracking force down to max of whatever cart you have
place on foam rubber with a layer of denser rubber below, idealy one density for each type of jolt it will recieve but i think some mat and a sheet of matress foam will suffice.

Or (/and) get a linear tracking table from the 80s/90s

I was like what 5K USD for 1500x3000 cnc plasma cutter with power source and pipe cutting option? Shit this machines got cheap now a days I remember when the cheapest of this stuff was around 40k.
Of course you are getting stepper motors instead of servos and some other budget stuff, but a 5k for a machine like that??

So anyone have one of this cheap Chinese cnc plasma cutting machines?

Is it possible to use these 4 terminals in combination with 2 graetz bridge and 2 capacitor to power the amplifier?

Amplifier uses +/-36V
Transformer gives 31V, when converted to DC gives ~34 volts.

Also how can I get negative voltage from this.

I want to create a clear engine lid for my MR2 SW20 that looks like the one from a Ferrari F40, pic related. It has to be clear, maybe slightly tinted.

I can get the part as FRP (fiber reinforced plastic) for not so much money, but of course it's not clear.

How can I create a mold from this large thing?
And what material should I use to cast?
It has to be light and UV-resistant.

Seems impossible to me, especially the first requirement.

I would like to install a switch on my dashboard to disable/enable the drivers side airbag. If I cut the wire and put a switch on it, is there a risk of the airbag deploying when the power is suddenly turned on for it?

>> No.1730707

But why?
Just don't fasten the seatbelt, airbag won't go off.

>> No.1730791

Airbags have blown out when people have worked on dashboards without removing the fuse first. I higly doubt that they'd have removed the dash while wearing seatbelts.

>> No.1730804

if the airbag ecu has power it should be performing continuity test to ensure airbag is connected/not deployed.
very common for any work on airbags not only disconnect battery but discharge/short terminals or wait for discharge a few hours.

big question is why do you want it enable/disableable?

least intrusive would be remove airbag and replace with suitable impedance to trick the ecu. depending on your location and use this could get you in a fuckload of trouble under inspection, but so does your original idea.

i have had supplemental service procedures for older cars that insists headlights and ignition must be on before reconnect battery to reduce chance of accidental airbag deploy because of power surges.

if you have a vehicle that is available in opposite hand drive you could frankenstien something with a legit passenger airbag disable switch. you need an opposite drive side ecu if the car is capable of deploying select airbags dependent on impact type, which they all do. but its still fucking sketchy.

>> No.1730915

I'm short, and from what I've read the airbags are designed with a 177cm standard height. The airbag must be good for any normal drivers, but I don't like to add risks like severed retinas and overall worse head and neck injuries than I'd have without this safety feature.
And of course, it would need to be able to be quickly turned on when switching to a taller driver.

tldr I want to do a career in battery manufacturing, should I go EE, ME or CE? I got some real world experience in all three remanufacturing batteries for a forklift dealer but I want to go back to school. CE seems like the right idea but courses seem to focus on petroleum products, EE seems right too but focuses on installation and CS (as opposed to electrical-assisted manufacturing, like electroplating pic related), ME seems right because of metallurgy studies but seems focused on exclusively drilling operations. I also have a side job building specialty camera flash tubes, so I know a lot about radiation - would applying this to manufacturing require more chemist skills or machinist skills?

When you get down too it I want to be an electrochemist so I can do electromechanical machining.... is there any way to practically do this without just getting a 4-year degree in physics?

Asking here because /sci/ is clueless about real world job applications and /adv/ just wants homework and feels.

>> No.1730689

Find an uni which does research which looks interesting. See what faculty it's being done in. Then don't go there for bachelors, go somewhere cheap and transfer there for masters (assuming you're a burger).

That said, actually designing the batteries for manufacture is going to be mostly mechatronics ... the chemistry is someone else's problem.

>> No.1730701

>is there any way to practically do this without just getting a 4-year degree in physics?

Study manufacture engineering. You're still going to be learning a combination of math and physics, but it will be far more practical.

The other alternative is to study business. The economics of power distribution is changing fundamentally. People and things will be becoming far more mobile over the next 50 years.

And what you will learn about global economics and finance is relevant to understanding how the materials are sourced in politically unstable regions, or how to understand the changes in population dynamics. Just every time you have an elective, study something related to batteries.

Find a professor who does batteries, and talk to them.

Sup /diy/ I hope you guys are a good board to ask. So I want to make soap totally from scratch. Render fat myself, make the lye, make scented oil etc. I've figured out most of it, the only tricky part is making the lye.

I have lots of wood to use for ashes, that's no problem but I don't have anywhere good to cook it. It's not really the sort of thing I want to do in the house and I don't have a hot plate.

So I'm wondering, can I do it cold? If I dissolve in water, strain then dissolve more, strain again etc? Can I make it strong enough to get the soap to set?

>> No.1730498

Yes. The heating of the liquid is just to quicken evaporation. There is no chemical reaction taking place. Potassium hydroxide is normally mined but evaporite dissolution, albeit slow, should ultimatum yield the same result.

I should add, I've never made soap and don't know how 'strong' it needs to be. I do know that if you leave a solution with KOH in it out, it will eventually crystallize as the water evaporates. I'm guessing that's how you're suppose to separate the KOH from the other contaminants in the wood ash.

There are feedback servos that will give position data back to your microcontroller. It's positional feedback instead of force, but it might be close enough for your purposes. They cost a bit more than normal hobby servos though.
