MEP EP#214: It is Probably Safe

Parker

  • Just got back from vacation
    • Have not worked on any projects since last episode
  • Watched lots of old er James Bond movies
    • Should we do a Spy gadget episode if we can get the right guest?

  • Simulation of the Week: Behringer Model D Oscillator Core
    • Lots of cool stuff going on
    • Exponential converter
    • Constant current capacitor
    • Discrete opamp with discrete comparator
  • CNC Update
    • Base built and topped with a torsion box
      • ¾” MDF construction
    • Gantry is on but needs some love
    • New Spindle has 80mm mount
      • This does not fit on my current z axis
      • Make a mounting bracket with leftover aluminum from previous project
  • New transformer for rackmount guitar preamp
    • Old configuration was to do a 115:12.6 transformer then feed that into a 12:230 to get back up to high voltage
    • Simple math says 230/12 = 19.16 so, 12.6*19.16 = 241.41VRMS = 341.36VDC
    • In reality I am getting 250V….
    • Hopefully with the new transformer ratio I will get closer to 300V which would be a 20% increase
