Hey, that looks awesome! I noticed a little bit of "fray" on the edges of the band. Do you think some sandpaper could get rid of those?
10-18km, depending on how you ride it.
It's pretty much the same except the charging system. Use my old board schematics as reference, as well as my new charging system instructable!

The master is the Nunchuck, the slave is the skateboard. If the LED blinks erratically, try burning the fuses again.
Near the power in? Or the other circuit?
Like Scollins055 said, if you want strength you gotta go with a material that is difficult to compress. Pink EPS is softer than the material I used, and I wouldn't recommend trying it to be honest. The strength comes from the CF, but the farther apart the layers are, the stronger your deck will be. So if you use soft foam and it gets squished, then your deck will have less strength. I buy all of my stuff from fiberglass supplies down in Washington since it's nearby and cheap. I saw some of the same CF on eBay but it was maybe 1.5 times the price.
Not in this deck, but in my other deck I used unidirectional fiberglass under the top layers; that's why I said unidirectional!
Thank you! Hope it gets others to biuld it as well!
Well I have ridden about 40km on this board so far, is that what you mean?
Thank you! And you don't need to soak the epoxy all the way through. The vacuum bag compresses the carbon-fiber together, and spreads the epoxy thoroughly throughout the layers. Epoxy and glue are not interchangeable. And for your BMS question; yes, you can bypass the current limiter by connecting your ESC directly to the batteries. I'll be making a new tutorial on that shortly.
Thank you! It took a long time to plan things out and get it right the first time :)
Thank you! :)
Because it's stronger and it uses less epoxy (thus saving weight). It forms a better bond with the foam core, and I consider it critical for something like a skateboard deck.

For the last time, you are wrong. The Nunchuck does have enough resolution and travel to allow for adequate control of the speed, and it is nowhere near like a "forward/reverse on-off switch."I have used this Nunchuck to comfortably accelerate from stop to max speed many times on an open track. Maybe your implementation of the Nunchuck did not have enough resolution to do the task, but mine most certainly does.
Trust me, I've used RC remotes before as well (I have built 5 electric skateboards so far, some with RC remotes, and some with smartphone control even), and I absolutely disagree with you when you said that they don't have "enough resolution" and that they are "awful compared to an RC controller." While the travel range of the Nunchuck is less than that of a standard RC remote, the "resolution" is still there; my nunchuck has 1024 steps between the maximum and the minimum speeds, which is more than enough to provide for firm, safe control of the speed. (My smartphone controller has the same resolution, and it works safely as well)I did watch the Metro-board video and I understand how it operates.

(My smartphone controller has the same resolution, and it works safely as well)I did watch the Metro-board video and I understand how it operates. They use an off-the-shelf wireless nunchuck and they simply integrate it with the ESC in some way (I'm guessing similar to the Wii Receiver/Arduino). Why they went with that incremental system is beyond me; it could be because that particular receiver doesn't have a very good resolution. My receiver works just fine, and I have used it countless times with the skateboard under me.
You must have gotten a Nunchuck with a worn out potentiometer. It happens, but I recon RC controllers use potentiometers as well, so it really just a matter of how good the potentiometer is, and not where you originally get it from.
True, but I wanted it to be compatible with my smartphone controller!
Thank you! And awesome!
Thank you! (Although I did build my longboards first :P)
