MEP EP #163: The Golden Integrated Circuit

The Golden Integrated Circuit

Parker

• Propeller Development Stick Type-C Addition
  
  • Found the BQ24165RGET to handle the lithium battery power management
  • New battery management IC handles dual inputs thus replacing the TPS2113ADRBR power mux and p-channel mosfet
• Wagon Tach Project
  
  • Signal is a 50V pulse from the distributor
  • Arduinos do not like 50V
• Wagon Powered Mirror PCB Installed!
  
  • 3D printed a bracket and installed into the door
• Tag Connect Probe Ends
  
  • Will give a full report on how well they work

Stephen

• Macro Amp
  
  • Milling the top panel
  • Transformers mounted - check!
  • PCB mounting needs fasteners ordered
    
  • J-Fet buffer for the NuTubes
• Riaa filter with gain options for MM and MC type
  
  • A series of filter specifications for recording
  • If the record is cut with lower bass then the cut width can be smaller allowing for more info to be cut on to the record - More music playing time
  • Two poles and one zero
    

R.F.O.

• Gain ultra-high power density for 100-W USB Power Delivery adapters
  
  • Texas Instruments application document for a very dense, high power AC to DC power supply
  • Designed around providing the power for a 100W USB Type-C charger
    
• Complete 5-Watt Power Supply in IEC Main Filter Case
  
  • Combines a IEC60320 (C13 coupler) connector with EMI filtering and a AC to DC power supply
  • Greatly simplifies product design
  • Due to cost Parker only sees this used in low volume / high margin products and one off art installations
    
• TI Claims Breakthrough BAW Technology
  
  • Bulk Acoustic Wave (BAW) resonator technology though should it be BAWRT?
  • Will reduce BoM cost and PCB size
• Discussion on how to store parts
  
  • Part bins, boxes for projects, and proper tool storage
  • Parker's fasteners drawer is getting out of hand
  • How do you organize your parts?

Announcements!

KiCon 2019 is a user conference for the popular open source CAD program KiCad. Happening April 26th and 27th 2019 in Chicago IL, this is the first and largest gathering of hardware developers using KiCad. Talks at the conference will span hardware design, revision control, scripting, manufacturing considerations, proper library management and getting started developing the underlying tools. All announced talks have been listed on the conference site.
