I have finally decided to enter the 3D printing bandwagon. Having room for more hardware have always been the main inhibiting factor for not having done it longer ago. But with a little tidying up of the available space the impossible eventually became a reality. At least that was my reasoning, and the selection of a small resin printer seemed like an interesting choice in that respect, at least in what concerns the space occupied by the device itself.
In the previous post I had the chance of discovering and documenting most of what there is to learn about the communication between the LCD unit and the master ESC (speed controller) that drives the e-Scooter rear motor.
Most e-Scooters and other Electric Vehicles have some form of Electronic Speed Controller (ESC) which is responsible for delivering a power signal that will spin motors at the desired speed. The most common type of motors today are of the BLDC type (Brushless DC motors), which are typically driven by a 3-phase current.
One thing about these types of electric vehicles is that there is very limited care for normalisation, when it comes to allow different components to interoperate. Especially in respect to the digital communication between the parts of the system, one cannot expect any baseline currently.
I just went on holidays and did a road trip. Because Murphy is always lurking, I was taken by surprise with runaway window wipers. No matter what position of the wiper stalk, these would run in intermittent mode all the time, as long as the ignition would be on.
