• Sensors circuits work
• The heat sink of the voltage regulator burned my finger.  It has an overheat cut-off so it shouldn’t damage anything if it gets to hot.  That said its best to give it more surface to dissipate the heat to.  Its designed to be bolted to the board, maybe that is enough.
• p(watts) = dv * i (power dissipation of a voltage regulator)
• Its possible the current is higher then when I tested it.   Not sure why that would be.
• Need to find slightly thinner bolts.
• In retrospect I should have used the dead zone on the board for the i2c bus.  Only one per 8 Fingers is necessary.  There is still room to drill holes and mount it on one of them.
• Started assembling the bus

End: 6:00
