EP#123: Jiggling Jumper Cables

• Stephen
  • The uTracer 3 
    • A tube curve tracer that is very powerful.
    • Some upgrades that are in the mix 
      • New interface for selecting socket connections - going to have 8 and 9 pin sockets with rotary switches for each pin
      • Upgraded ground loop for measuring the grid current on triodes
      • Integrated FTDI
      • Transistor curve tracer (only tests the "positive" transistors PNP,N-Channel stuff)
    • Lab Notebook: http://dos4ever.com/uTracerNotebook/Notebook.html#Plate
  • SSPS - The entropy creator
• Parker
  • New Article: Key Parts of an Arduino: How to Integrate the Arduino Platform into your Product
  • Reading temperature NTC thermistors 
    • Voltage divider method
    • Wheatstone bridge circuit
    • Dedicated IC like the MAX6682MUA
    • Others ways?
  • Are space ships and space suits rated for external positive pressure?
