Some parts arrived. 1st challenge: mounting the sprocket onto the motor shaft.
With much help from @FranzImsch and @TheVale98 I first turned custom adjusting rings, which will keep the sprocket from wobbling side to side.
For my first piece on a lathe it's acceptable imo 1/2
First spin up successful ✅
The motor and ESC work very well and it's a tiny bit scary tbh ^^'
Tomorrow I'll hopefully be able to build the motor mount and with a bit of luck it'll already experience it's maiden voyage!
After that I still have many details to work out.
Today the motor mount got ~70% finished.
Done: Chop sawing the base plate, triangle and edge blocks. Drilling the mounting holes, CNC cutting the motor plate and lots of drilling and tapping.
ToDo: Drilling + tapping the remaining 4 out of 6 sides of the edge blocks.
Maiden voyage was a big success!
Project #ePocketBike milestone 1 reached ✅
But there is still _a lot_ left to do ^^"
Massive thanks to @vale_1998, @FranzImsch and @patagona for your help thus far, I couldn't have done it without you
More wiring for the I/O board and box.
Handlebar connections are done, the rest is WIP.
Didn't finish the power wiring tho... (Had to go home at some point ^^')
Finally! The wiring for the #ePocketBike is done!
Preliminary tests show that the ESC still works and the DIY hall-sensored brake lever too!
(For controlled recuperative braking)
Although the signal of it is a bit noisy, probably need to fix it at some point ^^'
Now I can finally get to the fun part: Writing firmware ^^
[07.06.2023]
Just in time for #GPN21, I mounted the display and quickly hacked together the serial communication, so the actual data coming from the VESC gets displayed on the dashboard I coded last year.
I still need to revamp the layout and some values, now that I actually know what metrics I get from the VESC and what I want to actually display.
First time working with fiberglass and epoxy to reinforce the seat of the #ePocketBike.
Either the aluminum underconstruction or the fiberglass laminate by themselves would probably have sufficed, but there's no engineering like overengineering :P
Big thanks to @techbeard, @hmnd and @crexodon for their help. I literally couldn't have done it without them <3
New experience in unfamiliar territory unlocked: upholstery.
Since the original #ePocketBike seat foam was pretty beat up (see past post) and thin to begin with, I decided to completely reupholster it.
I cut a slab of composite foam roughly in shape, glued it to the now reinforced seat base and trimmed it to shape.
Then I wrapped some fabric around it, marked it and used it as a template to cut out the leather pieces.
Now all that was left was sewing the pieces together and stapling it on.
