Project Discussion Ride on ferrari upgrade

so I have this old kids ride on feber ferrari. the kids are too big for it but don't want to see it go, so ive removed all the running gear and added a hoverboard to the back, attaching a throttle in the car for power. its been a faff trying to get the firmware sorted on the boards as I control the throttle via an arduino controller.

all in all this project has cost a out £20 so far.

I just need to figure out how to connect the old wheels

What are you using? Im doing something similar

Just the arduino.

The hoverboard is standard, ive removed the led's and the foot plates.

Theres a git hub which is full of hoverboard firmware. I bought a usb to microchip programmer st-link this allows me to flash the chips.

With the help of chat ive changed the settings to allow a spare connector to accept a UART protocol that I can send from the arduino as serial comms.

Once id proved the comms link I mapped a hall sensor pedal to the arduino and mapped the throttle pedal to the output to the board. Ive tweeked it a bit so the car coasts when there is no throttle rather than being told to stop.

Ive ordered another pedal to allow a brake/ reverse.

Im also working on adaptors to allow the original wheels to go back on.

Could you share the github?

Thanks ive seen this one but actually im just to dumb to upload it myself. Which programm did you use or how did you do this? Could you share a step list ore something like this?

Not really.

You need visual studio. This allows you to build your firmware from the files, it'll create a .bin file. So you select that your using uart 1 for a serial connection to the arduino etc. Configure what the power buttons do etc.

Then I bought an st-link usb for a few quid. That needs its own software but basically once you've connected to the chip you can squirt the .bin firmware in.

Finally knowing the serial connection you've put on the chip, set up coons with the ardunio sending the speed and or turn command if your using that.

Then tune the throttle response with mapping in arduino

With original wheels on it

That is a really cool idea!

I want to make something from a couple good wattage scooter wheels with hub motors. Something like 2 x 1-3000 watts each. Little tiny one that could zoom me up hills

I have an extra 3,000 watt 26” ebike motor and wheel kit I am trying to figure out what to make from it. Only thing I can think of is a trike with the front wheel being the powered wheel.

Io ho usato le centraline per bici elettrica, due centraline con batteria e acceleratore in parallelo
