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
