Currents from 0.03 to 0.07 amp "can" start to impair the ability of the person to breathe, but the most dangerous currents are actully from 0.1 to about 0.2 amp. Currents in this range can cause death by uncontrollable twitching of the heart(fibrillation) which stops the regular flow of blood to the body. Currents a lot bigger than 0.1 amp do NOT result in fibrillation . They do stop the heart completely though. If this happens and the the duration of the current is short, the heart will "usually"(not always) start to beat by itself after the current is removed.
Be safe and ground and read, flame all you want, but a lot of people actully have no busness building these lasers IMHO. I read things on lasersaur that scare me, people not knowing basic things about electricity, it seems here safety is more of a concern and rightfully so.

There is risk involved in a project like this and you can get hurt, but I believe I have addressed the safety issues and made people aware of potential issues to safe operation. Perhaps you are not talking about me/this community but just lasersaur?
