Hi, i'd like to ask the community for some help. Now that our wheels cost more money and are widely known to (some) people, are prone to stealing. We had a case of a friend here in Greece that someone stole his KS16S when he was buying some coffee. Me personally, i rock a Nikola Plus 100V with the 21700 cells, that from what i've seen so far from other wheels and my one, no-one uses the on-board USB charging port, so i thought why not REVERSING IT, so it can be used from inside the wheel for a specific purpose or even diy stuff. For example see this : i've got so much empty space on the upper part of the wheel, a compartment that in other variants of the Nikola (or plus) is filled with extra battery pack or even the actual board (see Nikola 84V) So, i'm thinking if i can have the 5V port inside the wheel i can install one of the following things : a gps tracker a spare android phone that is used as a gps tracker more speakers ( ) but last, the best thing that is missing from this wheel extra cooling fans cause as @Marty Backe mentioned in his video "First impressions" at 13:40 talks about the fan that is there just to circulate the air, cause this wheel doesn't have proper ventilation. So....... What are your opinions and/or suggestions about the reversal of the USB port, the possibilities are "∞" i also have a raspberry pi3 with a x4 breadboard, i could do so many things inside the wheel, but first things first i could REALLY install extra fans and circulate the air properly!!! Does anyone know how to reverse the usb port and make it internal ? maybe friends that know how things work, @esaj or @enaon ?

I just created a neat Arduino library to interface EUCs via Bluetooth or directly via the tx/rx connection of the motherboards. I have tested it with several older Gotway EUCs and I will try to add support for the newer Gotway protocol and also for the older King Song protocol. You can download the library on Github: https://github.com/T-vK/Electric-Unicycle-Interface I mainly wrote this for two main reasons: I wanted to make some cool LED effects like rotating LEDs at the precise speed of the Unicycle. To make a DIY Bluetooth smartwatch that displays the speed, battery status etc. The first one is ready to go as you can see in this video: A first prototype of the second one is sort of ready: Here is an example of how you can interface the EUC using my library: /* Simply receive the data the electric unicycle sends * and print it to the serial console on your PC. */ #include <SoftwareSerial.h> #include <EucInterface.h> //Bluetooth serial with rx on pin 9 and tx on pin 10 SoftwareSerial BluetoothSerial(9,10); Euc Euc(BluetoothSerial, BluetoothSerial); // Receive and transmit data via bluetooth void setup() { Serial.begin(250000); // We'll use the normal hardware serial to print out all the received data BluetoothSerial.begin(9600); // Most unicycles communicate @9600 baud over bluetooth Euc.setCallback(eucLoop); // Set a callback function in which we can receive all the data the unicycle sends } void loop() { Euc.tick(); // This simply needs to be called regularely } void eucLoop(float voltage, float speed, float tempMileage, float current, float temperature, float mileage, bool dataIsNew) { if (dataIsNew) { // new data received Serial.print("Voltage: "); Serial.print(voltage); Serial.println("V"); Serial.print("Current: "); Serial.print(current); Serial.println("A"); Serial.print("Speed: "); Serial.print(speed); Serial.println("km/h"); Serial.print("Total mileage: "); Serial.print(mileage,3); Serial.println("km"); Serial.print("Temp mileage: "); Serial.print(tempMileage,3); Serial.println("km"); Serial.print("Temperature: "); Serial.print(temperature); Serial.println(" deg Celsius"); Serial.println(""); Serial.println(""); } } This example uses the Bluetooth interface of the Unicycle. So you'll need a serial Bluetooth module for it. I highly recommend the HC-05 which can be found for less then 3 US$ on aliexpress. But don't worry, there are plenty of other examples in my repo: https://github.com/T-vK/Electric-Unicycle-Interface/tree/master/examples API docs Euc(ReceiverSerial, TransmitterSerial); //create new instance of this class Euc.tick(); // simply has to be called regularly Euc.setCallback(callbackFunction); // you have to specify a callback function to which the class can send the data it receives from the unicycle //Example callback function: void callbackFunction(float voltage, float speed, float tempMileage, float current, float temperature, float mileage, bool dataIsNew) { // Do something with the received data } Euc.beep(); // make the unicycle beep Euc.maddenMode(); // set it to madden mode Euc.comfortMode(); // set it to confort mode Euc.softMode(); // set it to soft mode Euc.calibrateAlignment(); // calibrate alignment Euc.disableLevel1Alarm(); // disable level 1 alarm Euc.disableLevel2Alarm(); // disable level 2 alarm Euc.enableAlarms(); // enable alarms Euc.enable6kmhTiltback(); // enable 6km/h tiltback Euc.disable6kmhTiltback(); // disable 6km/h tiltback

Hello , i want to ask , is it possible to control the hoverboard motherboard using an arduino ?please help my final project , thank you

They are a euc instructions for DIY made years ago http://www.instructables.com/id/Electric-unicycle-Arduino-DIY/ It can be updated with hub motor and wide pedals. Would be nice to have a collaborative open source project euc made in electricunicycle.org They are lot of features to discuss, like size, weight, power... but because is a open source project, the most important features is the scalability and compatibility. Firs the scalability allow more people access to the product. From the basic and cheap to the expensive and fullfil. Compatibility means easy to find parts for repair or upgrade. Freedom to the consumer with no restrictions from patents, if you want a handle cut off switch simply put it on. My setup for start is a light weight euc with 800w like IM v8 without shell for ease fixing and upgrade, mud guards and hardware encapsulation for water and dust protection. Because my old times with classic unicycles I like the seat with small handle, is useful for save the euc from falling, do jumps or just sitting
