MEP EP #161: Kalashinikaze: The Right to Fly Arms

Podcast Notes

  • Parker
    • Prop Dev Stick Type-C edition update
      • Routing almost complete
      • Moved from 0603 to 0402
      • Parallax Propeller moved from QFP to QFN
      • Changed the voltage regulator from a NCP1117 3.3V to a AP7361C 3.3V
        • Why?
      • Adding Lipo battery charging support
    • Testing my USB Type-C example boards
      • Interesting Dongle Type-A to Type-C
    • Wagon power mirror controller works!
  • Stephen
    • LND150 feedback tone stack for a Roz amp
      • Similar to the Venteq this is a variable impedance filter inside a feedback loop
      • Uses a modified architecture
      • LND150 makes up the active element
        • From ~80V to 400V it is linear and does not shift amplitude
      • High voltage power supply still working great
    • Macro Amp
      • Looking at the component layout
      • Need to get octal sockets and J-Fets for the buffers
  • R.F.O.

Stephen's.... questionable tone stack prototype using the high voltage LND150. There is 400V running through this!
