I'll let Adam speak about hardware.
We still have a couple software bugs that only occur after running overnight.
Once I have time to correct those and pin-connect a few features, Adam has plans to do a shakedown using a rough and tumble Golf cart as the mule.
It's hard to make progress with only 24 hours in a day and a day job and family and the necessity for sleep. And I'm not as young as I think I am.
Nice to hear that there is an interest.
