Virtual Earth Mixers

April 8, 2020 Hosted by Parker Dillmann, Stephen Kraig

Datasheets are usually an engineer's friend. However, Stephen finds that his rotary switch's datasheets do not match the physical device.

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
