guppydrv DUAL Clicky Firmware Option
This firmware allows the ultimate in user customizability, with 22 built-in mode groups, that the user can select via a series of button presses and a user programmable turbo timer that will automatically step the power down to 50% after the set time is hit (see below for instructions).
Low voltage protection: With 1S cells (non-zener mod) the light will begin to step down output at around 2.8v under load. The light will not shut completely off, but will continue to run at a moonlight level.
User Selectable Groups:
To switch mode groups: rapidly tap the switch 8 times, the light will then enter the programming mode and begin to flash. With the light in programming mode, tap the switch the same number of times as your desired mode group. The light will blink and your mode group will be memorized.
Example: To select mode group 3, tap the switch 8 times quickly to enter programming mode. As soon as the light enters programming mode and beings flashing, tap the switch three times. The light will blink to recognize the mode group change.
To set the turbo timer: rapidly tap the switch 8 times, the light will then enter the programming mode and begin to flash. With the light in programming mode, tap the switch 30 times to enter the turbo timer set mode. The light will then switch to 100% power. When the light is at the desired temperature for the turbo step down, turn the light off. The turbo timer will then be set. The turbo timer steps the light down to 50% regardless of the mode group set.
