Minutes

• @Fil Maksimovic

  • playing with FPGA (https://tinyfpga.com/, ICE40LP8K)

  • discussion about

• @Jackson Paddock

  • got a larger board made

  • believe @Austin Patel was wire-bonding

• @Andrew Fearing

  • sent a couple of links

• @Thomas Watteyne

  • discussing DC833M, https://www.fanstel.com/bc833

• @Austin Patel

  • did some wirebonding

  • may have understood why wirebonding wasn’t attaching to SCuM pads

  • wirebonded VDD/VBAT/GND, was able to connect headers, seeing 300uA from SCuM, which is good. Could also connect Teensy but something wrong with connection, e.g. VDDD (no voltage on the pin)

  • @David Burnett discussion about Teensy and multimeter woud allow @Joshua Alexander to test out boards

  • @Jackson Paddock can assemble a new large board

  • @Joshua Alexander to order a Teensy and multimeter or Analog Discovery to test board

  • @Austin Patel about McCoy, wirebonded, but when trying to connect VBAT and GND, something was shorting

  • @Andrew Fearing thinks he has the equipment to get a board tested

  • @Austin Patel can hand off a board to @Andrew Fearing . Just board with headers (@Kristofer PISTER confirms no SCuM)

  • discussion about temp profile of the reflow oven

  • @Alex Moreno helped assemble the small board

• @Said Alvarado-Marin

  • DotBot 1.3 built (see below)

  • working on single PCB design, schematic is ready, ETA Mar 8, 2021

• @Razanne Abu-Aisheh

  • exploration completes! GitHub - openwsn-berkeley/Atlas at develop

  • gives a demo an explanation about algorithm, runs demo

  • writing a paper about mapping speed vs. packet loss
