Electric longboards are awsome!

HOW TO BUILD AN ELECTRIC LONGBOARD CONTROLLED FROM A PHONE WITH BLUETOOTH
Update #1: Grip tape installed, some tweaks to the speed controller have meant I have got more speed out of the board but range has stayed the same! video coming soon. Working on nunchuck controller as well.

So I thought I would stray a bit from multirotors for this post and write a log of how I built my electric longboard. It has been something I have wanted to get for a while now and with all the projects I have been doing on my CNC, I decided to build one myself. (Could’t really use the CNC as it doesn't have a very large work area) I am going to start by giving an outline of my project goals and how I intended to achieve them:
1. It must be of sufficient length and width to make it stable.
2. It must be capable of reasonable speed (15+ mph).
3. The range must be at least 8 miles as my nearest town is about 4 miles away.
4. I want to be able to control the longboard with my phone (android).
5. I want to have a voltage readout on my phone so I know how much battery remains.
WARNINGS: The code and app are not perfect by any means, they are very much still in beta. Please be careful with the stop button as depending on what esc you use, the brakes can be very aggressive and may throw you off the board.
Disclaimer: I am not responsible if you fall off your board and/or hurt yourself in any way because the acceleration or braking or speed is too aggressive due to my app/code/any part of this “tutorial”. If you use my code and app please test thoroughly with your particular set-up to make sure it doesn't hurt you. It may take some tweaking… If you have any queries then leave a comment :)

There are two aspects of this project that I think will be most difficult. First, mounting a motor to the trucks of the long board and setting up a drive train. (I have a plan for this) Secondly is going to be the way to communicate between the ESC (the device that contra the motor) and my phone. For the first problem I am going to use a company called dielectric skateboards.com who make trucks with motor mounts are welded on and they come with pulleys and a belt and wheels. (I was going to build this part myself but I was under time constraint and I wanted to spend most of the time working on the electronics.) (See my PLANS page on my blog (https://skyhighrc.wordpress.com/)for some ideas on making a motor mount) With that problem sorted we move on to the electronics. I am going to use an arduino nano and a bluetooth module (HC-05) to control the board from my phone. To write the app I am going to use Mit App Inventor which is a free on-line tool for building simple apps.
