Look what I found on my shelf ! A Pair of fresh Hand Held Portable "solar death ray" lenses , (potentially) I'll have a look through the big versions on YouTube to see how they are framed etc etc , I also found a collection of old CD & DVD burners & readers that I collected over the...

I am by no way a tree hugging greenie & when I saw this guy's "alternate" solar death ray setup ~9 months ago , I made a few sketches of my own , definately not for "green" purposes... https://www.youtube.com/watch?v=eeSyHgO5fmQ I'm glad he seems to have no knowledge or formal education in...

Have I posted this question in the right section ? Surely someone knows if these 100mW IR lasers need to have a current limiting resistor soldered in series in either the red or black wire ? A seller was nice enough to reply with these halfway useful temperature ranges , for these particular...
