MadBull secret project, should be released in 1~2 months
I am not good with electronics but I know some of you are and might have a guess.
Not the tracer unit which we show you guys last week: http://www.youtube.com/watch?v=Xp0TaknPdWY
Not for your gearbox, tracer silencer or battery, but something else.
I will keep it quiet for now but this product will surprise you guys!
Part of PCB board design attached.
