@Austin Patel update on hardware assembly
progress on assembling the small boards
50 big boards arrived (with popcorn!)
step 1: silver epoxy SCuM to board
step 2: heat to cure for 15 min at 120C
discussion about wire bonding procedure
@Jackson Paddock is free to help out
Alex and I (and Jackson) are going into lab today to do more assembly
@Jackson Paddock
presents slides on First process corner simulation
initial draft of thesis outline, to be discussion 1:1 with @Kristofer PISTER
@Fil Maksimovic
SCuM, using one of the Q board
wasn’t able to program using optical, will try with 3-wire bus
will try lighthouse v2 with SCuM
enjoying the reverse engineering thread on lighthouse v2, similar functionality to GPS (https://github.com/cnlohr/esptracker/issues/1 )
SCuM cannot receive the bit (FSK modulated signal), but maybe can do energy detect
discussion about the nRF52840 DK as a programmer (https://www.nordicsemi.com/Software-and-Tools/Development-Kits/nRF52840-DK). @Kristofer PISTER to send e-mail. No update from @Said Alvarado-Marin
