neo 2.2, what cap?
 

i have read that it is better tio fit a cap to protect the lazer but which one. people say 100v 1uf, 10v 63 uf, 5 v 100 uf, i have not got a clue? i have fitted a 100v 1uf cap & a 240 ohm resistor seems to work ok. any ideas?

Search the forum on "Arakon" who posted this stuff in the first place. He gives the answer and I believe you'll find your values to provide the necessary protection. But check - i'm not 100% sure about the microfarads.
