Hello i just received my host diode driver combo and put it together and after about 15 second it starts to blink at around 10-20 hz maybe even 30 i am not sure but the first 10 secs are fine then it blinks so safely id say 650 mA cause i selected mine for 700mA i am going to post a video of it on youtube to show how fast and how powerful this is!!!! it burns wood plastic everything

-Edit First It starts blinking slowly then speeds up as time goes on keeping this laser off for now!
Have you tried a different cell? A slow blink could mean overheating but rapid pulsing usually is a current issue either from a bad cell or a weak contact point in the host.
Jordan is right. Usually it happens because of contact problem or overheating.
Did you add a heatsink to the main IC of the driver ? ...
Also , try to put it in a different heatsink or just assemble it again to check if there is any contact problem.
