MEP EP#254: Ridiculous Relay Ratings

• 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
