MEP EP#335: Your Toaster is Toast

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.
