Esk8 Engineering Presentation

Hello there!

My name is Jake De Necochea. I am the Engineering Marketing Intern at the Northern California Grow Manufacturing Initiative (GMI). My job is to help connect advanced manufacturers to educators in order to train a skilled workforce for the future of manufacturing. I have been asked to create a presentation for junior high and high school students about my esk8 board, the engineering practices I used, constraints, versions, problems, and the future of my board.

I wanted to get input from the community as to what should be included in this presentation. While this is more about inspiring kids about what you can do with engineering, I also want to bring awareness to the hobby.

I use this board as my primary mode of transportion, so I am constantly upgrading and innovating. It is used to solve a problem, which is why it is being used in the presentation.

So, in terms of education, what is important? At the presentation, should I allow kids to ride the board? What sort of visuals should I implement?

Thanks in advance!

Esc’s for SURE! Also motors, switches, batteries, and mechanics.

I would say no just because it’s very dangerous for those who can’t ride(roast me brothas :wink:) and your board is probably illegal too :stuck_out_tongue_winking_eye:. But you can show them you riding it. :grin:

I planned on all of that, but I think describing how everything works would be a great idea.

They aren’t actually illegal in california, as long as it doesn’t go over 20mph and has headlights, tail lights, and reflectors on the side. I plan to conform to everything except speed soon :joy:

I think it’s important to make it not to complex but make sure they understand the basics :slight_smile: Maybe you could use the guide I wrote :slight_smile:

2000 watt limit. If you are using 6374 or dual, you’re already broken the law :rofl:

The motor I am using is 6364 190kv 2000 watts… and I plan to upgrade to dual for sure… Oh well!

Official verdict. No one can ride it but me.

That is beautiful! Can I use some of the pictures? I will use my own wording, but the pictures are really nice

@ZackoryCramer @e.board_solutions

I linked the presentation so far if you want to take a look. It is in edit in the original post.

I don’t have acces, I would be interesting to have a good presentation others could use aswell :slight_smile:

Fixed. I would be happy to upload the presentation when it is completely finished, the more publicity the better!

You should try explain the electronics with the water analogy. Easier for younglings to understand

Battery = bottle of water. High discharge = 1 litre bottle with big cap, low discharge = wine bottle

Current = amount of water passing through Voltage = water pressure Resistance = tight neck or pipe restricting water flow Switch = valve

Motor = water wheel, more pressure (voltage) = more speed. More water (current) = more torque. Low kv = big water wheel, high kv = small water wheel

Voltage, I push that. Resistor, I hold that. Current, I flow that.

:wink:

I fully Disagree with what you’ve said about scooters being safe and longboards Unstable. Here is something me and @Deckoz wrote up about the scooters and longboards,

This is so true. Also the difference between skateboarders and longboarders. Helmets aren’t even a question when it comes to longboarding

That does make a lot of sense actually. I will change that. Are scooters more stable than long boards though? There really isn’t much opportunity for speed wobble in a scooter as far as I can tell.

I like that idea. I explained how the motor works using a cat chasing its tail.

Tail=magnetic fields created by stator coils Head=magnets in rotor

If you let go of the scooter handles your wheel will make you fly off somewhere, And if you fall from standing position Like holding scooter handles you will have a bigger impact on the ground. these are just some things that are easy to explain. Don’t want to get into the whole topic of how longboard trucks are stable across 4 wheels speed wobbles only occur when riding loose etc.

And why write “smaller wheels=less torque required” I mean Lower gearing, lower motor KV = more Torque, It seems like a desperate attempt to seem smart,

Its not a desperate attempt, the rest is explained later. That was one of the main factors in the decision before even starting research on motors and all that, so I thought it necessary to put it there. I changed the electric vehicles slide to match more with what you are saying.

cool dude, Like your build its just like mine just I got 9s higher amperage cells. oh and 25mph+ more like 23mph ( if you use the keda 190kv.).what 8s lipos will you use? If there like 20c then you’ll get voltage sag uphill.
