  • original generation of COBOL programmers where expecting their programs to be replaced (or at least rewritten) within a decade or so – and then Y2K and we realized how much COBOL was still in the wild – and now a couple decades down the line, they’re still having problems trying to convince fintech to switch from COBOL to the new language of Java …






  • similar to a drum, the empty space inside the case acts as a resonator and most of the dampening options try to fill in the space – EDIT: reminder that whatever you use, make sure it’s non-conductive

    • initial sound generation – silent switches, no long-pole stems – reminder that switches generate as much sound on upstroke as downstroke
    • dampening the plate response – burger mount, gasket mount
    • empty space between plate and PCB – most commonly filled in with laser cut Poron foam (“plate foam”)
    • empty space in case under PCB – filled in with a whole range of materials
      • most common currently also laser cut Poron foam (“case foam”)
      • early experiments with rubber shelf liner, Sorbothane (automotive audio dampener), and Poly-fil all with good affordable results
      • high-end DIY includes silicone pours – filling up the bottom of the case with silicone and letting it set in place (how-tos on Youtube)
