Can I put a wheel on a board?

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

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.

They go pretty fcking fast, controlled by attached remote, can climb hills upwards of 15-20MPH depending on the battery pack you go with

What you can do is designing it and then apply for a patent yourself. If it is accepted you should be fine.

Standing waves, if I'd take a crack at it without googling. Voltage, a propensity for flow. Current, the flow. Take two tuning forks at the same frequency and they'll resonate. Now, a difference tone is the dissonance caused by the beating from two different frequencies. If there is a phase difference inherent in an electric circuit, that differential frequency can be excited by resonance with another unseen frequency that's boosting its signal via constructive interference. That's all I have and now I'll google... Idunno boss, you tell me.

Cannanyone help having some trouble with this,


A signal extending from 0 to 15.0 kHz is sampled at a rate 20% greater than the minimum sampling rate given by the sampling theorem. Each sample is coded as an 8-bit binary word and transmitted as a sequence of eight binary symbols.

1.How many bits per second are generated by this process?
2.Calculate the minimum bandwidth required to transmit bits at this rate over a noise-free channel?

Hey, this is kinda long shot but here I go.

I want to create (or find) a program that will construct smith-goodman fatigue diagram for common steels. I'm studying mechanical engineering in eastern europe and the lectures weren't really thourough. I would really appreciate some help on this. Even some good literature online would be great help. Thanks.

Just having a bit of fun here, shooting some B-grade shit. I'm thinking about novel ways to create an auto-loading bow. I'm trying to imagine some advanced medieval weaponry where firearms (for whatever reason) have not been considered, but mechanical technology is still very sophisticated.

The pic related is just a quick mock-up. There would probably be a magazine above/below with bolts loaded. A second magazine is loaded near the top of the bow. Inside this are many very compressed springs that are tightly loaded, waiting to unload energy into a level that draws the bow back after a bolt clears the shaft.

I'll take some creative liberties if I have to, but I'm trying to make this as feasible as possible. Would enjoy hearing any arguments against it, or improvements.

Looking for quick help

get an arduino (link in code comments), modify this for 3 LEDs

[code]
/*
Most Arduinos have an on-board LED you can control. On the UNO, MEGA and ZERO
it is attached to digital pin 13, on MKR1000 on pin 6. LED_BUILTIN is set to
the correct LED pin independent of which board is used.
If you want to know what pin the on-board LED is connected to on your Arduino
model, check the Technical Specs of your board at:

// the setup function runs once when you press reset or power the board
void setup() {
// initialize digital pin LED_BUILTIN as an output.
pinMode(LED_BUILTIN, OUTPUT);

-if you're going to get some thing from the truck, take something with you that you're done with
-use common sense, pay attention
-communicate. If you "didnt quite get that" or you've been told to do some thing you're not familiar with, or maybe you're a little familiar, don't just say "ok" and go try to do it. You're going to waste the person's time after they walk away to come back abd show you. Just have them show you first, thoroughly, and ask questions to fill in any blanks that they neglected.
-don't be stupid. If it's too heavy, don't try to lift it. Think you're going to smash a window carrying around that extension ladder? Ask for help.
-that being said, you can carry a lot at once. Grab that tool bag, and the other tool bag, and the trash, and that hammer drill, and bring it all up those 2 flights of stairs from the basement to the truck. Don't be a pussy.
-if you're on a site that's a long term project, make sure you know what you're doing on a given day. Plugging and switching? Full a box with plugs switches and plates, and throw in some 3ways and GFIs in there too, for good measure. Then go around and put that shit in. But make note of things that aren't right: boxes that aren't flush, pinched wires in the sheetrock (fuck those guys), etc. Carry a notepad, write shit down.
-get a project apron. Your toolbelt isn't enough, you need some thing to keep wire nuts in, or screws, or staples so you don't have to keep using your pocket and ripping open your ballsack.

I'm currently enrolled in an Electrical Engineering program and I was wondering how well you guys document your lab notebooks. I ask because I was recently partnered up with a guy who was enrolled at a more prestigious(albeit expensive) school and when we were doing the lab I noticed how good his notebook looked and I kind of want to get better at mine, to the point where I'm considering taking a technical drawing class just so I can be more accurate. Are there any resources you gentlemen might know of that show good practices for notebook keeping, when I do google searches all I find are how to properly maintain a lab notebook, which doesn't help at all.

And penmanship, are any of you also sloppy writers? How do you overcome that in the notebooks?

And just to continue the conversation, what kind of engineering notebooks do you guys use, and why did you pick it?
