Podcast Notes

  • Stephen
    • Nasty Analog Oscillations
      • Opamps are drama queens of electronics
      • Solved the oscillation with a small capacitor in the feedback loop to lower the frequency of the feedback
  • Parker
    • Waiting on circuit boards to be built for the DAC Article
    • Reworking the Knowledge Base here at the FAB
      • Suggestions for topics are welcome!
  • RFO
    • Voyager 1 Fires Up Thrusters After 37 Years
      • Trajectory Correction Maneuver or TCM thrusters
      • TCM’s where only used for continuous firing mode and not used to angle the craft which requires controlled burst firing
      • Engineers used decades-old data and examined the software that was coded in an outdated assembler language to figure out how to test the TCMs
      • Electric propulsion coaxial
    • 0306 Capacitor Size
      • Odd capacitor size
      • Same dimensions as a 0603 but hamburger style
      • For reducing the parasitic inductance by shortening the current loops in circuits
      • AVX product brief on low inductance chip capacitors
    • A Concise Guide to Ceramic Capacitor Types
      • Covers the different classes of capacitors
      • “Why does Y5V even exist?”
    • Four Levels of project transcendence
      • 5th level is starting a lifetime of projects every month but only abandoning them after ordering all the parts and supplies for said projects
  • Announcements
    • Twitter Chat Info
      • April 6th Friday at 1PM CST
    • Meetup Info
    • Houston Hardware Happy Hour
      • First Thursday of each month
      • May 3rd at Slowpokes
      • Bring hacks and hang out

DAC Test Fixture PCB


PCB holder and alignment part. This will be 3D printed and then mounted on the test fixture PCB.


The four levels of project transcendence!


Special thanks to whixr over at Tymkrs for the intro and outro!
