I’m slowly gathering my pack parts (I’ll pick up my shell just after Halloween from Garrick/knowone251 at Know One’s Designs) and am trying to do the electronics myself with Arduino. I have prototypes of the [cyclotron](https://www.gbfans.com/wiki/equipment/proton-pack/cyclotron) and powercell lights working - I’m using RGB LEDs so I can change colors if I wish, just waiting on final parts from China (and the shell for fitting)… But I can’t seem to find any references regarding if the speed of the cyclotron lights and the powercell lights change while the wand is firing or recharging, or are they always consistent? Thanks! ---

If you want movie accurate then the pack lights stay consistent. If you want Game accurate then the pack lights speed up until the vent initiates ---

Perfect, thanks! So clearly that means a Mark II Game Pack as well… 😉
