If you were using the airsoft drive method for the cannon smoke based on my 2nd video
https://youtu.be/LsyNWb6HzX8
but we have found out that this method is NOT reliable and not consistent.
Using this DC to DC convertor + trigger board (which also controls the pump timing, consistently) is far more reliable so we made this just for your convenience!
(note: new versions of Cannon Smoke come with this setup now)
Get this if you don't have this.
There are 2 variants, one for CL*RK TK (using JST-GH plug)
and another for IBU, as the flash (trigger) plug is JST-XH 2.5mm for these.
