Here is my first DIY red (650nm) laser ever.
my other DIYs are here (All terrain torch) and here (micro laser)
It has a somewhat visible beam at night (but cannot be used for stargazing as the beam isn't visible enough).
Runs off 4XAA batteries (one circuit with reed relay) and 2X 9V Batteries (in parallel for the laser).
It will burn (almost instantly) an unmarked match and through text on paper.
Its main feature however is it's 'child proof' and safety technology! I think it is one of the first lasers of its kind to incorporate safety as well as power!
It has a key start, missile launch switch (also emergency stop switch (see video)), & light up push switch (all of which have to be on before laser will work)
It also has 3 indicator lights to show when the laser is powered up.
Pics below. (if vids will actually upload I will say sorry now for terrible quality, but its good enough for you to get the gist...)
