Is it just me or did they add a blue laser to this now?If you have never made a LUMIA -- here is an easy way to cover the lasers you need for a small one.
less than 20$ make an offer( I just offered 13$ each for two of them-prolly get turned down but...)
Hot Sell Mini Projector R G DJ Disco Light Stage Xmas Party Laser Lighting Show | eBay
the listing says item ships from USA- this listing does not show the mW of the red and green lasers- at least they are not claiming more that the real output= hard to LPM these so I guess they are around 20mW 532 and maybe 60mW of red- fine for small LUMIA box-
I got a few of these as returned not working the motor inside that rotates the diff grates. had a loose wire-
i was about to solder and thought.. why not use this as the R & G for a LUMIA_ should run a long time OK- has a tiny fan on the back-- the circuit inside turns each laser on and off at times- so that works for me- very small- ez to mount using the bracket it comes with and mine had a mic and sound response too-so does this one-- hard to beat 20$ for what you get - ready to use- nothing to do except mount and aim thru your LUMIA glass-
After the lasers go thru the LUMIA glass I am quite sure these will then be eye safe- still don't want to aim into people eyes but should be safe enough for 'normal' uses.
Maybe 'Massdrop' can get us a deal on 100 of these --
have fun!! Hak
