Show Notes

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"
