>tfw you spend £400 a month on propeller hoverboard research
I've been doing this for a year and a half, am I a madman or a visionary? I think I'm getting somewhere, calculations checked over and approved by /sci/ (although I never said it was for a hoverboard at the time) say that it's feasible on paper at least.

get a fucking patent and stop talking about it you retard.

Yes and it will suck, because there is no way to steer it. You should have realised that friction is an essential part in drivina skateboard, nerd.

Bring it on faggot. But seriously yes I will get a patent. I heard it's hard though.
>>7617683
Let's see you do it then. And FYI his achievement wasn't simply making it fly but proving that the computer can still stabilize it even when it's 80 kg top-heavy
>>7617688
You're right control systems has been the biggest problem, the actual lifting the weight part is pretty clear cut (spin the propeller). I don't know what code he was using but my version is improving.
>>7617676
Add more propellers.

Control isn't that hard at all. Just like quadrotos, all it needs is a gyroscope in the middle to auto-stabilize itself in the air.
But yeah, this is useless unless it starts using fuel rather than electricity. Also the power consumption will be much larger than vehicles since it has to push the hoverboard against the gravity unlike cars where it just has to push it forward.

OP, why don't do you something different? Propeller-based hover boards aren't anything new. You'd be a visionary if you were finding a way to achieve anti-gravity or something like that.

Which would never happen considering manipulating gravity for recreational purposes is not only physically impossible, but completely impractical.

You'r just a tinkerer anon, but a madman for even considering the visionary thing. lel cool stuff tho show it flying.

>>7618910
Propellers are the most straightforward method, they're not pretty but they werk. Even if anti-gravity is at all possible I doubt one guy in his garage is gonna work that one out. Doesn't matter whether it's new or not, I don't see any propeller hoverboards on the market right now. What kind of flight times should I be getting before it's worth trying to market it? 5 mins? 10 mins? 20 mins?

propellers; field propulsion is a classified technology.

If the hoverboard in that pic worked for 10 minutes instead of 20 seconds would /sci/ buy it?

If you're in the US you would have to be retarded to fail to get a patent. The patent office issues invalid and duplicate patents all the time.

One thing I will remember when this is done is that absolutely no-one took me seriously. But I bet you same haters will be lining up to buy it.

Uh, it looks cool. I would do the actual hovercraft thing and put a skirt around it to better direct airflow downward.

I'm sure there's a loli fart joke in there somewhere.

It was stupid for him to even ride the thing without securing the blades. You need these around the hoverboard so they dont turn into a meatgrinder
