EP#114: Chasing Oscillations

45 minutes

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  - Engineers used decades-old data and examined the software that was coded in an outdated assembler language to figure out how to test the TCMs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 abandon them after ordering all the parts and supplies for said projects
