never mind, I will find my way about tiny capacitors, tnx for scheme, now I have somethin' to play with hole summer

oh sh't, just occured to me, how the heck do I know the voltage on the capacitors??
By size? if so, somebody post a chart, a table or somethin', much appreciate it

Yo' guys wouldn't happen to know if there is a LM317 for surface soldering, would ya?

right im confused

i am building a diy red and i used the lm317 circuit and im plan on using a 6v battery will this not work?

i have read some posts on this topic saying that you need at least 7v and anything under will drain the battery instantly or that the laser will stop working when the battery gets half used becaus it will be underpowered is this true ?

thanks jamie
