Project: Diff Probe

  • Circuit Cellar design
  • Hack a Day project
  • Active Differential probe with 600V Common mode and 600V differential mode
  • Measure virtually any two points. No need for ground reference.
  • Perhaps a battery system with a boost converter?
  • Excuse to finally use that 3d printer to make a case
  • Basically all precision components

UtracerV6 enclosure

  • Decided to make an enclosure that better suits my use case
  • Stripped down from last time. It does not need all the bells and whistles from last time.
  • Fixed sockets
  • FTDI and SMPS for 6.3V and 19.5V

EOL: The Chip Shortage You Don’t See Coming

  • Instant obsolescence
  • No phase-out period
    • Foundries are booked three years out
    • Suppliers are working on their most profitable lines and filling standing orders
    • New fabs coming online won’t be buying old wafer equipment
    • New foundries will be making new parts
  • Avoiding instant obsolescence
    • What parts are more readily available and are continuity coming back into stock
    • Look at the market segments using the components you need
    • Put out orders for the components that you need regardless of lead times.
