So an update from engineering:
New board layout is almost done and ready to be fabbed any day now. This is our 4th board and we've fixing a lot the problems we discovered on from testing the crap out of the 3rd.
We're modifying how the water flows through the unit. Can't say more yet, but it's super cool!
With the wifi troubles we've seen, we're making two changes:
- External antenna to the wifi chip, extending the range 3x.
- Ethernet port so we can always hardwire, if necessary.
Our goal is to ship our first of these units in 5 weeks. Stay tuned!
