PKE meter electronics
The PKE meter wouldn’t be much without a good set of electronics. I picked these up from the resident expert in custom prop electronics, Hyperdyne Labs. These electronics are especially nice because they include a dual-mode display screen. Research has shown that there were multiple versions of the prop used as the PKE meter. These versions differed in that the sequencing LEDs in the main display were oriented in different directions. One version had the LEDs sequencing top-left to bottom-right, while the other version went from bottom-left to top-right. The display board for these electronics can sequence in either direction as dictated by a simple input switch. The electronics kit also features:
- dual-mode display screen with sequencing LEDs
- variable frequency sound effects that increase/decrease with wing position
- driver circuit for wing LEDs with adjustable frequency
- servo driver circuit to move wings up and down
