Advanced Wiring & Usage
Wiring a general Power-On Indicator / Accent LED
It’s is sometimes useful (or good looking) to have a LED lighting up as soon as the kill
key is removed. Of course, 1 of the 7 accent LEDs could still blink as idle mode
indicator, but a permanently on LED could be nice to simply indicate the battery pack
is working properly. This is also very nice to have indicator lighting up the internal ring
of a chromed anti-vandal switch.
The PC board provides a regulated 3.3V pad for that purpose, shown in purple in the
illustration below.

Add a crystal chamber to your saber
A crystal chamber is a nice detail to add to your saber. The crystal can be lit up by a
multicolor LED which can mirror the blade behavior, for more realism. This way, the
crystal chamber color is affected by the Flash on Clash color, or simply by the main
blade flicker.
Whether you use or not the color extender board, FlexiBlend driving signals (PWM)
can be extracted to power the crystal chamber LED. Ideally, you’ll need to use an LED
that matches your high-power LED setup. For instance, if you are using a RGB tri-
rebel, the best choice is obviously a RGB accent LEDs. You will need a common
cathode type of LED, those are fairly common on ebay and in many electronic parts
outlets. Like the other accent LED pad, the maximum available current per PWM signal
is 18 mA. Most LEDs are bright and fully happy with 5 to 10 mA.
