Fox flasher MkII update 7/2019

Fox Flasher MkII and several follow on articles described an animal deterrent based on a Chinese 8051 architecture microcontroller, the STC15F104E. This is an update after several years operation outside, and some in service modifications to improve performance. Above is the original basic schematic. Above is the revised schematic. One only high current LED driver … Continue reading Fox flasher MkII update 7/2019

Fox flasher MkII – high power 2 LED solar powered beacon

Fox flasher MkII – owenduffy.net described an animal deterrent based on an STC 8051 microcontroller and running from a single LiPo cell. This article describes a further development using a solar cell, shunt regulator, 1S LiPo cell with protection board, and two high power red LEDs. Above, the unit constructed in a medium size Jiffy box, … Continue reading Fox flasher MkII – high power 2 LED solar powered beacon

Fox flasher MkII #3

Fox flasher MkII described a LED driver for an animal deterrent using a Chinese 8051 architecture microcontroller, the STC15F104E. Above, the schematic. A very simple circuit with just a handful of electronic components (one capacitor, two resistors, one LDR, one Polyswitch, 4 x LEDs and the MCU). Last update: 13th June, 2019, 8:37 AM
