Great product.
Pint had it's time.
When the OneWheel+ XR** 2.0?
(easy sustained 20 mph, + another batch of miles to the range?)
...footpad led, simple stop option, pint style battery box protection on fender/delete, better connector housing, tire options, pint/XR pushback option, better water protection,
don't hold your breath.
From the sound of it, FM may have been consolidating it's EV-MFG infrastructure since the Pint. Possibly with the intentions of leasing their infrastructure to other manufacturers. If true, it's smart bc it permits a broader product base to hedge their risk. That lowers costs, which increases profits, which in turn permits greater diversification of their own product line. It would also have provided a long RnD cycle to develop the next iteration of the Onewheel.
Considering how polished the Pint is, I would not be surprised if a new XR is actually quite far into development. Well past an initial prototype. 100v batteries are a thing now, and a 1000w hub motor probably wouldn't be all that out of the question. Just a matter of engineering.
@blkwalnutgrwr Nice one! Shame I missed it but thanks for sharing the screenie~
Seems like you and Frank are going to be racing eachother up the ranks now ;)

Swapped the resistor, issue persists!
So that means the ST1480AB chip might be dead. Good thing it's replaceable.
Having to order from China because Mouser, Digikey and Farnell are all out of stock for this chip with an expected wait time of November. Found one on eBay so ordered that. Gonna take a while since shipping seems to be economy.
While I had the board out I gave it some more poking with the multimetre. Traced back the pins on the other side of the chip, they all lead back to the ARM chip (stm32f103VB) as suggested by the datasheet for the ST1480AB. The actual via's are under the chip so I spent a while probing everywhere coming up empty till I realised there were some under the chip I had to probe from behind.
Here's what that all looks like.
The other 4 (3 since 2 are connected) pins coming off the ST1480AB appear to go back to 3 I/O pins on the ARM chip. They'll be programmed in the firmware for reading the data. Assuming those are where the pins are meant to go then no break/short appears to be present.
So with that all in mind it brings me back to ST1480AB is bad or... the Arm chip. Fingers crossed it's the ST1480AB otherwise some sort of hack will be needed to tell the ARM chip to ignore battery info if at all possible.
I'd like to imagine it's ST1480AB that died and in turn caused the resistor to die, or the resistor died and caused ST1480AB to die... Either way it makes more sense that it's the problem. We'll have to see when this replacement comes in... a few weeks >.>
Pre-covid I was planning a 6 month+ road trip across the US. I'd just secured my visa before the situation started to spiral and I decided to take a rain check.
For later in the year if I'm lucky, or more likely next year, I'd like to bring my OneWheel XR+. Now obviously this can't fly with me, so how does one ship items with batteries? Is there a boat based shipping process I can transport the board with?
People do this for repairs at Future Motion, right?

awsome Lia! you are great at capturing character, but the x-stream girl from planet Catwheel is still a ghost!
so glad you got the time "off" to do this.
ps the tiedye looks great
