EP#107: Orthogonal for Mutual Conductance

  • Stephen
    • Melted Solid State Relay in electric brewery setup
      • "Finally gave up the smoke"
      • New SSR is rated for 40A
      • Installed a blower fan on the heatsink for extra protection
    • GFCI Breakers
      • Monitors current on both legs of the circuit and makes sure they are within 5mA of each other
      • Parker is going to use a SPA 240V 50A GFCI setup for his brewery setup
  • Parker
    • DAC board update
      • PCM5122 based DAC design
      • Same chip as what is on the HiFiberry DAC+
      • Had to change out the in series resistors from 1K Ohm to 27 Ohm resistors to get the communication to work
      • Digital Logic Analyzer Verse Oscilloscope
    • Soldering Iron ownership history
  • R.F.O.
    • PCM2912A USB microphone chip
      • USB Interface, Mono Microphone Input and Stereo Headphone Output
    • Found in a Datasheet for LAN9514 pg 15
      • When disabling port power, the driver will actively drive a ‘0’
    • The BenHeck show is losing its host
    • Adventures in Autorouting
      • /r/electronics thread
      • It is definitely written by a software person
      • They do not take in account RF noise, stability, power return and ground loops
      • “Imagine today’s standard 4 layer boards routinely being fit into 2 layers without any human effort.”
