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

Kalashinikaze: The Right to Fly Arms

• 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
      • BQ24075 Ti part
  • 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.
  • Know your fits and tolerances
    
    • Great video covering tolerances and fits for mechanical design
    • New engineers - selecting tolerance too tight. Most of the time this is not needed.
    • Fits - Ansi standards
    • Machinists handbook 30th edition $35 on Amazon.
  • Pillow Flight game
    • Pico-8 game
  • The Kalashnikov assault rifle changed the world. Now there’s a Kalashnikov kamikaze drone.
    • How will the future of hobby drones be affected by this?
    • FAA Mandates External Registration Markings for Drones
    • Hunting traps in most states have this requirement
    • Kalashnikov also makes an Electric Vehicle?
    • This reminds us of when the Media was scared that 3D printers could make "Ghost Guns"
