Minutes

• Andrew Fearing

  • DC/DC converter measurement results

  • New recommended components yield results much closer to datasheet expectations

  • Much lower ripple when current draw is 10x lower than typical radio current; good news for timer stability

  • Large cap on battery side (DCDC input) will be necessary when using DCDC with high source resistances, e.g., printed batteries

• Alex Moreno

  • Printed battery to DCDC to SCuM tests

  • Planning to revise method of battery current measurement

  • Expected 16 hr battery life; tested approx 10 hrs w/ inefficient DCDC component choice

• Thomas Watteyne

  • impressions of MRS 2021: /wiki/spaces/DOT/pages/1949237252 (ask Thomas Watteyne if for some reason you don’t have access)
