I just got the notification that my new handle has been printed and is ready to be picked up. I took the suggestion to get it printed 20% larger and used Zispinhoff's suggestion for a new pcb since the originals I had made at oshpark will now be too small. Currently, i only have two buttons and a hat connected to my original teardrop handle. I'm definitely looking forward to seeing what my options are once i get the new one here to mess with. I have a bunch of extra buttons and a second hat that i could set up if i can find a place for them.
I'm also looking into assigning a button to lock/hold the inputs. So if Im cruising or want to lift my hand, I can hit a button and the current inputs will be locked until i press it again. I know there's a related fork on github here:
https://github.com/jerdavis/DeltaThrottle , so i plan on looking at the code and adapting that. so, there's another button that i'll need to add!
