fast (200ms) = 10s lock-out\n- Red LED: vib sw detected (always active, even during lock-out)\n- Green LED: display sensitivity (blink 1x/2x/3x/4x), 1=most, 4=least\n- Blue sw:\n  - first press: display sensitivity \u0026 reset lock-out\n  - press again within 2s: change sensitivity (1/2/3/4)\n- White sw next to microcontroller: program mode (cut power to exit)\n\nCircuit Notes\n-------------\n\n### Net motion detector\n\n- Vibration detection switch \"SW-18010\" https://www.adafruit.com/product/1766\n- Sensitivity is adjusted by requiring toggles in multiple 10ms windows: sensitivity 1\n  requires just one toggle, 2 requires toggles in 2x 10ms within 100ms of one-another,\n  3 requires toggles in 2^2 = 4x 10ms intervals, 4 requires 8x 10ms intervals \n\n### Sensitivity switch\n\n- Pushbutton to change sensitivity\n- On-board sensitivity indicator LED (1, 2, 3, or 4 flashes)\n\n### High power Cree LED\n\n- Amber 5mm LED: C503B-ABS, 4430mcd @20mA, 40mA max continuous\n- drive using 2N4401 w/82Ω -\u003e ~40mA\n\n### High power \"flash\" LED\n\n(Not used due to size concerns)\n\n- Wire-up raw flashlight LED\n  - 135mA@2.8V=1/3W\n  - 220mA@2.85V=0.6W\n- 2N4401: 600mA max\n  - resistor emitter-ground: 10Ω-\u003e1W flash\n- On-board indicator LED\n- To disassemble flashlight:\n  - pull zoom ring hard and unscrew, remove driver\n  - remove btn cap, punch btn through alum housing\n\nArduino\n-------\n\nTo use `arduino-cli` install according to first post:\n- https://forum.pjrc.com/threads/53548-Arduino-CLI-Alpha-Release-Teensy-Support\nInstead of `arduino-cli core install teensy:avr` run:\n- `arduino-cli core update-index`\n- `arduino-cli core install teensy:arm`\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Ftve%2Fnetflasher","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Ftve%2Fnetflasher","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Ftve%2Fnetflasher/lists"}
