Electric Longboard DIY Help

Hello,
(unfortunately my french isn’t sufficient… sorry)

I am a student from Switzerland, who is about to finish high school, for that I am going to need to make a work/project. For that I chose to build an electric longboard. I already started to build the deck out of some hardwood and painted it. I also ordered some wheels and trucks (Orangatang Kegel). In addition to that I already prepared the big and small pulley for the drive train. I also chose a motor (Turing sky 190kv 2450w).
In order to control the acceleration i would like to use a wii Nunchuck, since that one has an agronomic build and two additional buttons. The only problem is: How do I convert and program it?
A lot of people, that build an electric skateboard have used 2 x 5000 mAh lipos 3s 20c batteries, I would like to use 2 x 8000 mAh lipos 3s 30c, is this possible, do ‘only’ gain more range air is there more advantages/disadvantages?
What kind of ESC should I use, a lot have suggested a 100 or even 150 amp ESC to prevent overheating…

Thank you very much for your help

Hi sean !
you should move your topic here : viewforum.php?f=7
Do you know Endless Sphere ? https://endless-sphere.com/forums/viewf … c6e945e9a9
If you are better in english than in french it would be easier to get answer there :wink:

I didn’t used a nunchuck so i can’t help you sorry…
For you batteries, you will get more range but it will be longer to recharge them and the 8Ah are much bigger, expensive and heavier than 5Ah.
For example, the 5AH (http://www.hobbyking.com/hobbyking/stor … _Pack.html)
are 26x49x145 and the 8AH (http://www.hobbyking.com/hobbyking/stor … _Pack.html)
are 27x70x170.

The best is a VESC ( dedicated for e-skate) but i think 100A should be ok

Hey sean !

Welcome here

Hi Tinties

Thank you very much for you tips, I am quiet new to forums…

Hey sean !

Welcome here

Thank you very much :smiley:
Could you maybe tell me how to attach photos?

hi Sean !
Wellcome here !!
Its a good project :smiley:
you need to past your links here :arrow:
If I say right for nunchuck, you only use the skin, all the inside is to change … I recommande maybe GT2B or by a nunchuk already mount ($$).
you go for single motor ?
2x 6s in any case 5ah or 8ah … in my point is the number of “S” you got to low…maybe you need to go up in Voltage to ride easier. 8/9/10S got a good speed torque range.
higher V = less A, so the setup dont take hard Amp pick and all work better with à lowwer tension :slight_smile:
for esc, VESC is the best like say tinties.

Good ride !

Hi Riako,

Thank you for your help. Yes it will be a single drive. The motor that I have bought is normally for a quadcopter… I do not know if it maybe got to much frequency?

I always hear the VESC, is it meant the ESC from Vedder? If so where can I get it, I can not find a place where I can order it. I have a ordinary Nunchuck, my plan is to cut of the board and only use the trigger and the buttons, so no gyro. I checked on Vedders website, there he has mentioned a Nunchuck controller, that is possible to be programmed for my uses, is that true?

thanks again Sean

I know of 3 sources for the VESC: diyelectricskateboard.com enertionboards.com and esk8.de
http://esk8.de/
the last one is the only one who has them in stock and with a reputable feedback, but they are more expensive:169€ (made in Germany)

It all depends on what you want/ are asked to do in your project: how much dIY does it need to be? I suppose you will have to justify your choices: cost/use/performance.
The VESC is better than another RC ESC because it is open source, designed especially for our e-vehicles, (for instance it does not get very hot and does’t need any heatsink/fans. You can totally customize your riding experience, use different types of controllers (Wii nunchuk, classic RC controller)

About the Wii nunchuk: although it is very iteresting (ability to reverse, do some cruise control) there is one main problem imho: the connexion is in bluetooth and subject to interferences when riding in an urban environment and you don’t want to lose control of your board in the street!
if you still want to go this way, you will need to build/buy the nunchuk pcb, it is more interesting to build/program for comprehension/education purpose but much more difficult and less “safe”.

Can you post your motor caracteristics?

Thanks for your help,

Is it possible to program the Nunchuk using an arduino board? I once saw a video from GreatScott I believe, he did exactly that, but his code, that he had provided are a bit messed up… He used some kind of antenna to send his codes to the ESC

ok it’s the good product!
