Laser Sight

[predro]

Hi All,
I think i'm what your refer to at the moment as a newbie. anyway i'm in the process of constructing a full suit and have just finished the final touches to my bio mask. After a lot of internet searching and research i found some great lasers for completing the 3 dot sight for your mask.
I managed to find an ebay shop which sells a pack of 5 laser sights for £8.99 (£1 postage).
I rigged 3 up to a 9v square battery and attached a 220ohm resister, it was very simple and got a some good advice from my local MAPLINS store. i have attached the link for the lasers should anyone wish to have a look.

If any one would want a picture then let me know and i'll post it.

Are these 650nm lasers?

Are these 650nm lasers?

Hi, yes they are,
values are as follows
1.8v to 2.4v operating voltage

2.0v current-10ma Output-1mw
2.2v current-20ma Output-4mw
2.4v current-25ma Output-6mw.

pretty safe values for lasers and have a more professional look than standard LED's
