    My e-longboard design

    Sorry I am not native english speaker, I don't get your question "Can this board support 5-7 lbs?" :) if you ask what is a weight of the board , so its 6Kg. About the screws - yes I use flat ones so you canot feel them from the top of the board. Length is different from 16 mm to 25mm. Now I...

    I made a little improvement to Alien Drive Kit, and now it works perfect.

    My e-longboard design

    Here is a source code for new controller algorithm. Features: Dynamic acceleration - faster in the beginning, slower in the end. Speed hold function - If "Z" button is pressed speed value are saved and board keeps the speed without joystick. And using joystick you can increase or decrease...

    Yes this Metro-board controller looks interesting, I will try to code it for my board and see if it is easier to use acceleration in this way.

    Thanks, No I do not have any problem because of the long cables. And no extra capacitors are used.

    My e-longboard design

    No I do not have brakes. I am thinking to change ESC, but not sure which one i should get. Now then I changed battery from 10S to 6S I think I have more options to choose not expensive ESC. Maybe someone can recommend me good and not expensive ESC with braking ??? Thanks.

    My e-longboard design

    Battery holds pretty ok, I used a 4mm screws and I drilled a board so screws comes out on the top of the board. But after a 10 km ride i found out that they get little bit unscrewed because of vibration I guess. So I have to find some solution for that. Yes I am running 1x SK3 - 6364 - 245 kv...

    For the battery enclosure I used about 1.2 mm plywood, I bought it here in Barcelona where I live now. To cut it I used a sharp knife (razor). And this battery enclosure is connected to the board using 10 screws, battery it self is not connected to the board. I have a 6S battery under it.

    No, I disconnect battery from ESC and connect to charger.

    My e-longboard design

    Thanks, I left a battery cable out of the back side, so I can reach it with out unscrewing battery case. My board is not very soft, but I have some flexibility with the mounted battery case as well.

    And here is an image how to connect wires , just in my case colors are mixed : white to A5, Red - GRND , Black - 3,3V , Blue - A4 If you use Arduino micro (like in my project) not UNO you have to change A5 and A4 to D2 and D3. And instead of a SERVO you connect to ESC.

    My e-longboard design

    Ohh, this is the worst part of my project, I didn't want to weld it so I drilled a hole in a truck and used a screw. But it broke after a test drive. Now I am using this Alien Drive Kit.

    My e-longboard design

    Yes it it wireless - Bluetooth. Here is short video how it works http://www.youtube.com/watch?v=5ywEanxQgSc I was surprised that connection is very stable. And joy-stick is quite responsive and costs just 10-12 EUR. If someone wants I can post more info, source code, libraries, how to connect...

    My e-longboard design

    Yes this is the one that I use, I just attached it on top of the ESC. I did just a few test rides so I am not sure if that fan is necessary, maybe ESC will not even get warm with 6S battery (which I am going to use instead of 10S).

    My e-longboard design

    Yes it was one charge, riding non-stop on my 10S batery. And about Wh/mi I actually dont know how to measure it :)

    My e-longboard design

    Yes sure, here is my order list from hobbyking, but if I would be ordering everything now, I would change almost everything ... ESC - no brakes , Motor - too big and heavy (never tried even half power of it) , battery - I do not need 10S in total 6S is enough, Servo Tester was used just for...

    Hello everyone, I was inspired by this forum to build my own electric longboard. So now I decided to share my project, which is still not finished but first concept already tested :) and hope to get some feedback from all of you...
