Wiring diagram for a blaster

Proffieboards
1

Hi all,
I am working on a project to build a Blade Runner blaster and install it with proffie. I want to use three “blades”: one with two and another one with five chainable neopixel LEDs, and a third blade with two green LEDs in parallel. Could someone check my wiring diagram, especially if the resistors are ok?

Many thanks!

This is what the blaster looks like right now :slight_smile:

Since the blades are short, you don’t need to link LED2/3 and LED3/4 together, other than that everything seems fine. The resistor seems reasonable, assuming the the LEDs really are ok with 3.8 volts.

Follow-up question: Is it ok if the third “blade” is defined as WS2811? Those are the two LEDs.
I used your configurator to get the blade config:

};
BladeConfig blades[] = {
 { 0, WS281XBladePtr<2, bladePin, Color8::GRB, PowerPINS<bladePowerPin2> >(),
    WS281XBladePtr<5, blade2Pin, Color8::GRB, PowerPINS<bladePowerPin4> >(),
    WS281XBladePtr<2, blade3Pin, Color8::GRB, PowerPINS<bladePowerPin1> >()
  , CONFIGARRAY(presets) },
};
#endif

No, they’re not WS281X LEDs. You’d configure it using SimpleBladePtr with a single led and blade pin.

There’s an option in the configurator for a single LED that demonstrates how this can be done.

You can just use CH2LED and of course whatever power pin you choose. (1 in this case it seems)

Like this?

};
BladeConfig blades[] = {
 { 0, WS281XBladePtr<2, bladePin, Color8::GRB, PowerPINS<bladePowerPin2> >(),
    WS281XBladePtr<5, blade2Pin, Color8::GRB, PowerPINS<bladePowerPin4> >(),
    SimpleBladePtr<CH2LED, NoLED, NoLED, NoLED, bladePowerPin1, -1, -1, -1>(),
    CONFIGARRAY(presets) },
};
#endif

Apologies if this is very basic.

Correct.
