If you were using the airsoft drive method for the cannon smoke based on my 2nd video
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.
