MEP EP#254: Ridiculous Relay Ratings

Parker

• PinoTaur updates REV 4
  • Automotive relays are not certified to run at the voltages we need
    • G2RL-1A-E-CV DC12
      • Max voltage rating is 300VDC
      • “Rated” current is 24VDC at 16A
    • G2RG-2A-X DC12
      • Rated at 500VDC at 10A
    • Looking at other relays used for this purpose in production machines… Am I missing something in choosing the correct relay?
  • RGB Light string split into two
    • Power current is the reason
• Foxconn Electronics hit by Ransomware
  • $34 million ransomware attack
  • Stole 100 GB of unencrypted files, and deleted 20-30 TB of backups.
• Bike rack as an inductor?
  • Other normal items that could be seen/used as a electrical components

• The FX Dev board returns
  • 2 versions of the fx dev board now exist
    • ProtoBoard
    • Protis 1
    • Both look like they ditched my ac power supply for a charge pump design
      • Protoboard uses TC1044SCPA
      • Charge pump to create a -9V from a +9V
      • Not sure what Protis uses but it is likely similar
      • FCC was a very big reason why I opted to do this
      • Negative Voltage Inverter
    • Both opted to not do the integrated soldered breadboard
      • This was the reason the FX dev board existed!
      • This helped make things very clean
