Features

  • HAGIWO design
  • Differences from HAGIWO
    • Using Arduino Pro Mini - smaller package than NANO
      • No USB but USB is not used after download anyway
    • Using I2C OLED
      • Probably affects screen refresh rates
  • OLED : 128*64 pixel 0.96inch
  • Knob1: Rotary encoder for selection (including push switch)
  • Knob2: GAIN
  • Toggle SW : AC/DC switching
  • TRIG IN : External trigger IN
  • Input : Signal to be observed IN
    • Observable voltage is 5 V p-p
  • Output : Observable signal OUT (short circuit with INPUT)

Design Details

Front Panel

  • Glue on OLED with a couple of drops of Hot Glue in corners
  • White on Black P Touch labels

  • OLED - replace connector with 1x4 right angle connector

  • Wiring
    • Green = Ground
    • Red = VCC (+5V)
    • Yellow = SCL
    • Blue = SDA

On Controls card

  • Wire top pin of R7 to top pin of R17 (connects J5 to J6 tip)
  • SW1 goes in cutout at J1
  • SW1 up = DC coupled, down = AC coupled
  • R7 stands up at bottom of R7 and wires to SW1 center
  • 4.7uF cap from SW1 top to SW1 bottom
    • + side of cap to SW1 bottom
    • - side of cap to SW1 top
  • Wire from J5 tip to SW1 bottom
