Action items

• Alex Moreno to upload presented slides onto page

Minutes

• 3wb (Fil Maksimovic )

  • tried 3wb on McCoy board, unfortunately doesn’t work

• McCoy 3.0 (Alex Moreno )

  • presents slides

  • discussion about DC-DC converters to use

  • created 2 variants, depending on paneling

  • discussion about battery clip and battery size (David Burnett shares https://www.mouser.com/datasheet/2/315/3635_fileversion-1627310.pdf )

  • Kristofer PISTER if coin cell: CR2032 would work, CR2477 has 1000 mAh

  • discussion about McCoy 2.0 vs McCoy 3.0. Problems:

    • VDDD problem: we don’t have a way to program using an nRF, need a constant 1.0V source

    • discussion about ability of nRF to run at 1.8V, Fil Maksimovic confirms that works

  • Kristofer PISTER discussion about issues with getting nRF and SCuM to work together at this point

    • 3wb?

    • 1.8V doesn’t work for tapping, we need a constant 1.0-1.2V source on VDDLDOOUT

  • discussion about issue with 3wb (Fil Maksimovic )

    • used a Teensy, using resister dividers to get to 1.5 and 1.8V, doesn’t program

    • Fil Maksimovic to program using 3wb holding VDDD

    • Fil Maksimovic describes challenges with the McCoy he has taken from Berkeley

  • challenge: getting 3wb running in Paris

• SCuM-programmer (Thomas Watteyne )

  • prepared user guide page: User Guide

  • will implement
