This summer I finished my second electric skateboard, and instead of using the usual Nunchuck remote I thought I would try to make my own. I am currently studying to become an electronics engineer, and recently bought a 3D-printer, so I thought it could be a fun summer project.
I have seen quite a lot of interesting remote builds on this forum, however many seems to me to be very complicated or an exaggeration with too many expensive components. I have always loved the simplicity of the Boosted Board remote, and therefor been trying to make something just like that - however powered by an Arduino.
This is the design I came up with
The remote consists of quite a few components, including an Arduino Nano, a NRF24 transmitter and a 3,7V 400mAh LiPo battery etc. You can find a list of all the components I used here:
The 3D-model is done and the STL-files can be found on my Thingiverse page in a few days - I have to make sure everything is fitting nicely before you guys waste perfectly good plastic
As you might see from the shopping list I use a linar Hall-effect sensor and two magnets to replace the more common potentiometer. The datasheet for SS495A says ”Ratiometric Linear sensors have a ratiometric output voltage, set by the supply voltage. It varies in proportion to the strength of the magnetic field”. By placing the sensor between two magnets (one north and one south) and moving the magnets over the sensor we get a nice throttle value.
I have been using my second prototype for more than 20km now and it feels very stable, however it has it flaws. I am therefore currently building a new prototype (the third). IMAGES !!
I would like to hear your thoughts and suggestions !! I will keep you guys posted with images and updates the next few days.
