Interesting Links and Articles

  • Rainbow Jellyfish PCB
    • Cute PCB design using bread board jumpers.
  • Fortran is still a thing
    • NASA is running a code optimization competition for a Navier-Stokes equation that is programmed in Fortran
    • Article goes over the strengths of the Fortran language and why it is still used
  • Good in a Pinch: The Physics of Crimped Connections
    • Why crimp connectors are better then soldering connectors
    • Covers the history of crimp connectors and the different kinds of crimps
    • The only down side to crimping connectors is having to buy specific dies and crimp tools that are generally expensive
