OP 1 flycut one side down, mill locating tabs down, M0 then flip, mill out and profile with corner round first side, leave locating/mounting tabs on both ends all 5 sides of them having been machined at this point
OP 2 use a plate fixture that holds all the profiled tangents, mounts and located off of the fully machined ends. finish profiling
OP 3 supported in soft jaw, put one end to stop, and have the other end towards spindle where gets corner rounded
OP 4 same as last op, you can do both ends in the same soft jaw, at the same time, on the opposing ends, assuming the operator is instructed to hold +/-.001 for tooling between OP1&2. On the first part and last part of the batch there's no support on the far end of the jaw, so it will sit cockeyed and need a support block used.

It should also be noted that if you're doing the spindle time in house and want to save money on not buying corner rounds, you could just hemstich the curvature with a ball nose. At the expense of added spindle hours to the part, especially if you don't have look ahead features or a high RPM spindle. Plus if the resolution and accuracy of the machine isn't there it might look like shit and need a lot of polishing.
Other wise you can always make corner rounds out of tool steel yourself. There's a number of tutorials on making profiling tools. Especially for cutting prototyping costs.

Open 'er up and check the wires leading to the buzzing speaker for rust/corrosion. Look carefully at the solder connecting the wires too, check for any cracks. You may have to de-solder the old wires off and affix a new one. It's pretty easy to do!

Working a small, essentially toy sized turret lathe. Decided for the way/gibs/geometry critical mechanical parts to be 1018 since it's fairly inexpensive, easy to get a hold of, and from my general understanding stable enough for precision mechanical parts. Looking through some general info on the alloy seems to indicate that no extra heat treating is needed, nor cryo, normalizing, pickling, etc. And once it's been rough cut, allowed to destress for a short period, then brought into final dimensions(milled, ground, lapped, scrapped) it shouldn't profoundly move on its own when at a room temperature.
Is this fairly true, or will this thing bow, and warp every which way by several tenths a few months latter?

I guess you`ll be fine. Let the thing cool back to ambient temperature between getting it into shape and taking off the final 1-0.5 mm. This should prevent any inaccuracies.

Low carbon non-alloyed steel doesn't benefit greatly from heat treatment, its still going to have bcc crystal structure at room temp so unless it's under significant stress it shouldn't warp.

Hi I'm actually an engineer so I'll give you guys a little lesson here. (Not being cocky just trying to wrestle with reality here.)

>Vacuumed out superhighways would save an incredible amount of energy (hundreds of millions of terajoules over a year kind of shit holy fuck use the petroleum to do something useful like terraform multiple layers of livable lithosphere)

>Supply independent CO2 scrubber units that utilize solar/wind/hydro energy to take shitty byproduct gasses out of the atmosphere, don't need to give it any thought just set her up and let her purify our existence.

>Traffic lights? This isn't 1900 bro. Energy savings by building independent direction cross sections (one going over the other with offramps) would save so many terajoules of energy even in a single year that you could power every city in the United States for a month. Every time you apply the brakes in your vehicle the very universe weeps from the entropic decay. (Average kinetic energy in a vehicle (depends on weight and velocity) is around 600k joules, you burn literally SIX HUNDRED KILOWATTS to fully stop your vehicle in ten seconds. That's enough to power your refrigerator for TEN HOURS every time you fully stop your vehicle from average highway speeds. Why does nobody care about that? Because gasoline is so hilariously inexpensive.

A general understanding of how the world works may get you into the realm of science, but the hard facts of the mathematics reveal just what everything IS.

List or explain the problems with these ideas for improving the efficiency/speed of 3d printers

1) a manufacturing line of 3d printers, something similar to ford, where each printer was setup to make one specific part for a project, and then you assemble those parts by hand, that could scale pretty well whilst still allowing you to change what you print with ease

2)increasing the number of print heads and decrease their size so they don't get in the way of each other on a single 3d printer.

3)with traditional methods of manufacture, mass produce small plastic pieces to a high precision that fix together tightly and be assembled in to any shape by a machine similar to a 3d printer, instead of melting plastic, it inserts one block on top of another (too small for human hands to do)

What about instead of extruding a plastic filament out of a pinhole sized nozzle extrude a plastic sheet through a wide enough slot to cover the entire print area. That would shave an entire dimension from the movement of the printhead making it that much faster by a factor of t^(1/3) to be exact.
The technology to close off the extruder at the necessary spots already exists, old needle paper printers used that principle. Just place a linear array of those actuated needles inside the slot-shaped nozzle.

Posted in the law section, but it might be better placed here due to the nature of my inquiry..

I really like the idea of the self-balancing single wheel skateboard.
Goes 15+MPH, durable, sturdy, and best of all (relatively) simple.

I'm wanting to re-create it with my own looks/ideas, but the patent issues for this type of technology seem cutthroat. Some other company was shut down at CES for having a similar one but the concept is so simple.

I don't know much of anything about the laws for these types of things I'm just a creative/techsavy type. I could have one made within a few weeks but am I going to get shut down because I have a board that uses a microchip to scan various times per second as to how a rider is leaning in order to deliver thrust in one direction or another? Or is it more of a design issue? Can the original creator of the skateboard come out and sue other skateboard companies for making them later on, demanding money and claiming they caused "irreparable damage" by making their own renditions of the same thing?

In all honesty I wouldn't mind selling them once I get a really good one made. The apparent original company for these "Future Motion" is selling them for upwards of $1,500-$2,500 and realistically I think I could make the same thing (if not better) for around $700-$800

No matter what you are doing somebody will always be around and have a patent and a bunch of lawyers who might potentially sue you. If your idea is something that you came up yourself and is not based on an existing product you are normally safe.
But if you want to build this exact thing and sell it because you think you can do it cheaper because a) normally you don't and b) duh this is exactly the kind of thing a patent is for, stop copycats.

Well that's exactly it, some of these self-balancing devices have lots of patents and are hunting those recreating the products (Razer and smart balance wheels)

But some other products like electric longboards have no patents at all, and practically anyone is capable of making their own rendition. Same with some of the electric self balancing unicycles.

Pic related, just one out of 5 or 6 electric boards you can buy in the U.S right now.

Hey, I'm an EE student asking the obligatory question: "What career would be best suited for me"
I am still not far into my studies and can choose a wide variety of specializations.

Unlike most of my fellow EE students, I am rather extroverted. A career as a developer locked up in a cubicle having to work on tiny details would be my death.

So here are a few specs of me:
  • I get bored easily and need a lot of stimulus, I am allergic to routine and micromanaging, I have to work on new subjects constantly.

  • When I'm excited I have limitless power and can focus straight for 15h developing stuff. When not, work is very exhausting and solving problems is hard because I don't get ideas.

  • I am rather creative and work intuitively. I like to think in big pictures and not in the details. I'm the one who gets a completly new way of solving the problem in the exam, not by juggling with formulas, but by looking it from a different aproach, but messes up and forgets so many details that he doens't get any points.

  • I really like talking, doing presentations, explaining and intorregating with sharp logic(asking others how exactly they ment that)

if you want to collapse the core your gonna need some VERY STRONG magnets, drills, charges (controlled as fuck as the crust isnt purely solid it has fractures & holes & allsorts which kill miners e.c.t).

First, well need to friends up or kill & impersonate someone "high up", with funds we can become a private interest in the many 'space programmes'. With the severe lack of funding NASA are recieving, they are playing ball to a lot more private interests & with their brains & techonology the charges could easily be places in the least dangerous palces meaning you dont die & can continue your mission).

To bore holes we will have to become frackers, we may need to relocate. The best places would either be the oil fields in asia as that has less crust & population to traverse or the American lands which are heavily fractured & drilled. If we impersonate or friends up the right people we will have access to underground networks, which go deeper than people think & are surprisingly stable. But once we have the licences for that, we will need similar minds to employ who hate things enough not to grass us up for depleting the polarity of the earth & reduction on key natural phases & fields.

With the resources we now currently own, not only do we not have to bury down ourselves, we can send people who hate things more than us & dgaf more than us. Reward their families amply if they get fucked up. That & we have a secure network of illegal activities intent on felling the clouds & allowing our precious shields to wander off into the vacuums of space.

Now you finally have the means to affect the polarity of the earth, you will need to connect the global power network, which there isnt yet. You would have to make one, but with our resources so far this will only take half a life time or so. Dw if you die or me there are plenty of other cunts we can trust. Now with the power, we can safely construct magnets at the entrance to the large bore holes & lower them near the crust before activating. Cables would need to be adamantium alloy as that stands up to even super heroes according to tv & comics so its pretty tough shit.

Now all which remains is for our calculation wizzes to be correct, the hardware not to fault (well have to employ asians & pay them well as were lazy & require cyanide). You now have, as I currently see it, 3 choices... which will be more effective I have not enough time to consider, like ever in my life.... You I recommend you take a shot & flip a coin, yelling fuck yeah.

A: Start both magnets at the same time in the hope this freezes the movement of molten materials & any magnetic materials will hopefully travel to the magnets, disrupting the orbital flow of the plasma & other materials. This could do nothing & just fuck every electronic ever up & stick us all to the ground via our belt buckles/tear things out of people bodies who have pins or heart tickers e.c.t

the fans will burn out almost instantly if you plug them into your mains. you're going to need an adapter. find out how many amps each fan will draw (either listed on the fan or by looking up the model number), add multiply by 4 for the 4 fans. that's how many amps your 12v adapter will have to supply.

12v 1a phone chargers are about $3 on ebay. you might evenbe able find one lying around somewhere.

Holy FUCK boys just COIL UP a transformer from mains to your fan load. If you can't calculate your fan load or the transformer ratio then you shouldn't be doing this shit.

Stay safe, better yourself, control reality.
