The motor side uses 2x 20amp blHeli esc’s (no bec’s), 2x Racerstar BR2205 2300kv CW and CCW brushless motors, and a MTD-01 brushed motor controller (dual motor controller).
Using a bulkhead mounted rheostat that is accessible on the outside. This adjusts the speed of the ESC’s. A USB connector allows connections without taking anything off the gun to the ItsyBitsy. The ItsyBitsy kill toggle switch is mounted to the outside to kill power to the ItsyBitsy.
There is a fan in the battery compartment to cool the 6v regulator (this provides the brushed dc motor power) and mtd-01 dc brushed motor controller . There is another fan on the body facing side of the rear bottom above the ESC’s.
Added a 3d printed nerf rail to mount the lithium ion battery.
The brushless cage is a 3d printed Regulator cage (same as in my Regulator gun). This is mounted on a 3d printed plastic shelf that allows me to screw into the shaved mounting holes that the oem cage was using, and then use standoffs to mount to the brushless cage.
Next to the ItsyBitsy inside, there is a 5v switching regulator. Next to the 5v regulator, is a small power distribution board that has rails for battery + ground, 5v + ground, and digital high + digital low (for use in the switches).
There are also 4 NeoPixels mounted inside the barrel with two of them shining directly inside the barrel, the other two provide light that is visible thru the barrel vent holes.
Initial light scheme is rainbow fading the 10 (5 on each side) that are attached to the fiber optics around the barrel when no triggers are pulled and the dart door is closed. The 4 inner led’s will be solid green. So if the gun is pointed at you, you’d see green shining out of the barrel.
With the first trigger pressed, the inner led’s go solid yellow. The outside led’s will cascade green.
With the second trigger pressed, the inner led’s go solid red. The outside led’s cascade red.
When the dart door is open, all the led’s go solid blue.
We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @ adafruit.com/blacklivesmatter
