• Resealing 12oz cans?
  • FAIL!
  • Worked till can shaken a bunch
  • Improvements
    • Working on finding a softer sealing surface
      • Currently using a Shore 55A neoprene rubber sheet
    • Increase seal pressure on can
• Carmakers wake up to new pecking order as chip crunch intensifies
  • Follow up from last week's discussion on Auto industry shutting down production due to lack of electrical components.
  • Both automakers and chip manufactures are pointing fingers
    • Chip makers point at the auto industry in that they are quick to cut production and cancel orders when car sales slump
  • Auto industry where used to being the center of attention for chip and electrical component manufacturers
    • The industry spends around $40 billion dollars a year on chips
    • By Comparison, Apple spends more on chips just to make iPhones!
    • Chips used in Auto tend to be more basic products and older micro controllers, Something that chip fabs do not really want to invest more production into
    • Chip Fabs are prioritizing higher margin, leading edge components
