you’ve seen those kidz lately with metal extensions on small skateboards… what happens if we properly engineer spring-steel extensions on ultra stiff decks and get the benefits of suspension and super stiff decks to add batteries and electronics on tiny skateboards…
this is my xmas gift to ya’all…
Think about it… tune-able plates that can be added or subtracted to tune your suspension, damping…none… but spriong… we got it! we’ll work on damping after the law suits are settled…
as you were
I have one…maybe the time has come to make something like a sepparate mcu for the boards?
Something that would control lights, give stats, would allow to plug in a horn, lately I have felt a need for an actual alarm system for the board…Something like Davega Pro maybe?
What about making a mental dd set with this motor
It wouldn’t even be a mental price if you know what you are doing
Two of these which the screw end bolts onto the truck and you make a specialised bearing for the wheel that has a slight hole for where the motor keyway can go into and you locative the bearing down onto the shaft
What do you guys think and I am not sure whether both shafts spin or only a single one does
This has been mentioned a bit in @linny’s stealth board thread but I’ve really liked the idea of a new type of hybrid esk8 that is a cross between a push board and a true esk8.
The idea is to have essentially a push skateboard with a one button remote in your hand. There is no electronic braking built in to the system, foot braking only. You push up to whatever speed you like while holding the button down and it acts as cruise control. This will ONLY match your top push speed. This button will not accelerate you at all. When you let go of the button, it goes back to a free-coasting push board.
Pros:
Concerns:
I’m just an idea guy… I lack the programming capabilities to make this work. I do feel that this product could be made with one motor, a small battery, and be very fun and affordable. Anyone want to play around with this concept over the winter with me?
Forewarning, if I don’t get positive feedback here I’m making a dedicated thread 
@Venom121212 There’s a core difference between your idea and the aforementioned one. You would like there to be a remote for the cruise control, whereas in the other, they are trying to fully eliminate the remote for ultimate stealth with cops. This means your goal is so much easier to reach as it wouldnt require the same level of AI or coding 
Do you have an idea of how @Wajdi implemented the cc on his remote? The remote had a momentary switch at the top that could be use for either cc, killswitch or reverse.
I do not. But I am hoping enough people take interest that can shed light on how easily this can be achieved. It seems like a pretty basic system all set up around the receiver/esc implementing one seemingly-simple command.
I feel like if an esc existed specifically for this product, the entire thing could be made for ~$300-400.
I just want an “endless” electric assisted push board.
Esk8 mecanum drive?
after an initial 250km/s burn to cancel galactic orbital motion I think it could be possible to escape the galaxy without any further propulsion (& reach a significant fraction of the speed of light at points in the journey)
Dyson spheres and interstellar engines! We need to move the entire solar system for a sustainable long term future. I imagine taking the sun with us as our battery/fuel source.
I had envisioned an AI course corrected craft carrying extremophile bacteria to other galaxies…
That’s much easier than moving a solar system. I’ll allow it.
or you can just fall straight in
So aside from the clear lack of relation to esk8, it’s my understanding that any object in space would be attracted to the gravitational force of any body in space, with the force of attraction being directly related to the size of the body. Are you suggesting that 250km/s would be the minimum speed to escape these forces and proceed outside of the galaxy?
@Zach 250km/s is roughly the speed the solar system orbits around the galaxy and by extension around the black hole sagittarius a* at the center which is 4 million solar masses, at a distance from the center of 27000 light years (the milky way galaxy has about a trillion solar masses). so you burn 250km/s in the opposite direction to cancel the orbital motion, and then fall straight to the center… the initial fall to the center would take about 63 million years or less, which is the same period of a quarter orbit at the galactic orbital velocity at our radius. since there are moving objects its possible to transfer some of the momentum of these objects to the spacecraft as well as increase the efficiency of any remaining fuel on board by performing an oberth maneuver at closest approach to the supermassive black hole.
Say what
Really confused what you are trying to prove here
with patience, one can go as fast as they want with an initial 250km/s burn.
for example if you have 250km/s inbound to the black hole at 100 light years distance, and at close approach (7.23x farther from the black hole than the earth is from the sun or periapsis distance of 7.23AU) you perform a 5km/s burn increasing the speed from 32301km/s to 32306km/s, when you are again 100 light years distant from the black hole, you would have around 645km/s outbound, thanks to the oberth effect multiplying the effctiveness of that burn 79x compared to doing the same burn while outbound at 250km/s, as shown:
^without increasing the speed by 5km/s at close approach, both inbound and outbound velocities would be 250km/s instead of 250km/s inbound and 645km/s outbound, assuming there are no other objects, for example. performing the same burn outbound at 250km/s would only achieve 255km/s, so the presence of the black hole multiplied the effectiveness of the 5km/s burn 79x.
^in this example, the craft initially doesn’t have escape velocity, and there are no engine burns, but the 400million solar mass black hole is being orbited by a bunch of stars and 100 solar mass black holes, and on the “first pass” the craft has an orbital period of 39 years, “second pass” 39 years, “third pass” 177 years, and on the “fourth pass” it achieves escape velocity from the system
Ok ill be the one to say it. I rarely understand any of what you say, but I’m glad that you are around to say it. You’re like esk8’s wacky uncle, and I always get a kick out of the stuff you post here on this electic skateboarding forum.
Also I have read most of what you have said about the Oberth effect, and I find it fascinating, if entirely beyond my mental capacity. Please keep posting your NSFPF (not safe for physics forum) ideas here, despite their lack of significance to esk8
