• Simulation of the Week: Behringer Model D Oscillator Core
  • Lots of cool stuff going on
  • Exponential converter
  • Constant current capacitor
  • Discrete opamp with discrete comparator
• CNC Update
  • Base built and topped with a torsion box
    • ¾” MDF construction
  • Gantry is on but needs some love
  • New Spindle has 80mm mount
    • This does not fit on my current z axis
    • Make a mounting bracket with leftover aluminum from previous project
• New transformer for rackmount guitar preamp
  • Old configuration was to do a 115:12.6 transformer then feed that into a 12:230 to get back up to high voltage
  • Simple math says 230/12 = 19.16 so, 12.6*19.16 = 241.41VRMS = 341.36VDC
  • In reality I am getting 250V….
  • Hopefully with the new transformer ratio I will get closer to 300V which would be a 20% increase
