This is basically Voyager V1 2.4GHZ Screen Remote Uni1 V2 compatible with VESC for DIY Electric Ska – Spintend.
I use two of these as they have built-in controls for lights. So does the Voyager V1.
I’m releasing my latest project this year to the community, it will be fully open source!
some specs:
1600mah battery
amoled touchscreen display
sakte and controller configuration
it uses ble to communicate with the receiver
wireless charging
it gets telemetry from vesc and BMS (jiabaida)
shake to turn on, automatic sleep
capacitive dead mans switch (it feels when its in your hand)
runs freeRTOS
I haven’t released it yet because im changing the architecture now.

Does it use Bluetooth for throttle/breaking communication? Are you concerned or had issues with lag or interference?
i had it in the beginning of the project when I was using esp-now, now that i use ble I had never experienced any lags or disconnections or jerky signals.
the only laggy thing is the UI for now, but i’m working on optimizing it now

How reliable is the dead man switch, are you able to turn off that feature.
Very cool. Has a lot of the features.

I am very worried about a touchscreen interface for the following reasons : costly, easily damaged (there are no ridges around the display to protect it when dropped/scraped, and easy to trigger /touch accidentally.
-
Looking for buttons for power on / off - maybe I am just missing where they are located.
-
Center of gravity - given the location of screen and batter it looks like the weight is in the “butt” which means it’s more likely to act like a throwing object - this is of course only a guess from what I can see.
-
Wireless charging - cool - more of a nice to have honestly.
I NEED ONE
it’s really realiable and responsive, it can also be calibrated to your grip, and it can be turned off on the controller menu, it’s also possible to invert throttle and reset to default configuration

1 - i think that’s the price to pay for a huge quality screen, but i’m thinking of ways to make it more robust without sacrificing the design
2 - there is no buttons to turn on/off, to turn of you slide down from the home screen and then there’s a slide to turn off, to turn back on you shake it hard, it turns off automatically if there is no activity and disconnected for 5 minutes
3 - the controller feels really well in the hands, the weight feels quite well distributed
4 - yep, qi wireless charging, that’s something everyone always asked for

What’s the expected BOM pricing like? Will you offer completed remotes in the future?

The plan is to release it when its fully stable because i’m still tweaking a few things, and also YES I’ll have a web page where you can order it and I’ll ship worldwide.
The expected price will be around $125 US dollars.

also I have the “lite” version which uses a cheap tft screen and normal usb charging and no dead man switch, but I wasn’t able to come up with a plan for the user to modify the parameters (motor pulley, wheel pulley, invert throttle, gear ratio) so i’m dropping it

Nice, do make a dedicated thread for this remote. A few friends as well as myself will be interested.

That also sounds really promising!
You could add a physical power button to the lite version and bring back the dead man switch as a physical input. That way, it could also double as a “confirm” button for navigating menus.
To enter and exit menu mode, maybe use a combo like holding the brake for 5 seconds with the dead man switch unpressed, or holding the brake and tapping the dead man switch three times.
And maybe for an even more cost effective display, you might consider a simple 128x64 OLED, although that would require more work on a new UI.
Definitely consider making a thread so we can follow your progress!
That lite version sounds more in line with what an esk8 remote should be IMO

If you are needing this information for speed and distance calcs you could avoid the whole thing by adding a drone GPS module to the remote.
I recently added these modules to all my boards displays and have totally fallen in love with it because a) it’s more accurate, b) it requires no data from the board and c) you can make changes to tire size, gear ratio, whatever and it doesn’t matter.
I just changed the tire size on one of my boards from 6" to 7" and didn’t have to touch any configuration parameters.
the issue is that they take a bit more time to lock in the signal and also they are power hungry, but will definitely look into it
This looks so cool!
