MEP EP#265: NuFuel and Gas Classic

  • 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



    • OnSemi plans to be back on schedule by 3rd Quarter



  • Eagle EDA Tool Designing parts from the bottom!


  • Starting a small business to sell hardware?

    • Tips for Parker?

    • This will be covered next week



  • DipTrace - PCB teardrops

    • Benefits


      • Stronger pad adhesion making for better reworkability

      • Prevents acid traps at sharp corners where traces meet a pad


        • This really is not an issue anymore



      • Inspect your board and run your DRC



    • Potentially make shorted pins appear worse

    • Offset


      • 125uV typ

      • 780uV max across temp

      • Input bias and input offset 10pA



    • 20V power


      • 750uA max across temperature supply current per channel



    • Rail to rail


      • 2k load 250mV from rail with 16V power

      • Drops to a fe mV with lower power





  • Cyberpunk is Real!

    • Porsche's e-fuel is like a real life CHOOH2
