MEP EP#219: Virtual Earth Mixers

Podcast Notes

Parker

  • Brewery Update
    • Still bending tubes
    • Going cheap and buying a roll of stainless steel tubing was a mistake
  • Started looking into the Jeep Fan controller project again
    • Evolving into a Body control module
    • Investigating the best way to add wireless remote control?
  • Pinotaur LED REV2 design is completed
    • Using those APA-102C-NEW-260
    • Working on a motor controller add-on for the Pinotaur board
      • Socketed motor controllers allow stepper or DC motor control

Stephen

  • Rotary switches
    • Three datasheets and all are wrong…
    • VAAPA: Variable Architecture And Parameters Amplifier
  •  CNC Update
    • Working on greater accuracy
    • Most cuts are within 0.005 but certain situations can make it up to 0.01
    • Got a O flute bit in.
    • Feeds and speeds
  • Analog tricks
    • Clipping opamp in feedback
    • Virtual earth mixer is no longer a virtual earth

Rapid Fire Opinion

  • Arrow Electronics launches European FPGA Developer Contest 2020
    • Entry via the Arrow European FPGA Developer Contest 2020 web page and choose from the following Intel FPGA development boards: MAX1000, CYC1000 or AnalogMAX /DAQ1/2/3
    • Projects can involve anything from software, special IPs/interfaces and soft cores, to board modifications, adapter creation, adding a PMOD/Arduino, creating an IoT device, and programming algorithms for AI/CNN
