No, doesn't look like it. I posted a comment a few weeks ago but he hasn't responded.Looks like the guy came up with a cool product. Wonder if he ever found a buyer?
I went back and looked at the vid comments. Apparently, not.

If you come up with any ideas I'd really appreciate it if you would post them or PM me. Sounds like what you are thinking (with a microcontroller) may be a little more advanced than what I was planing but still would like to hear your ideas if you pursue it.I think it's a good application for a microcontroller, and will give it some thought.
Thanks for the reply Danny. Could you please explain in a little more detail how a solar panel could work in my project? I need to activate a relay almost instantly after a laser hits the solar panel.Much easier to use a solar panel.
Have a look at this. http://www.allaboutcircuits.com/projects/laser-detection-system-using-a-picaxe/If you come up with any ideas I'd really appreciate it if you would post them or PM me.

Sounds like there are 1" LDR's out there so I'm going to give that a try if I can find one. If that ends up being to small I'll try some of the ideas suggested here. I think I'm going start with just controling a solinoid and some LED's using the LDR a mosfet and then a relay.
Cool! Thanks for writing the article! Very detailed, all the way down to the part numbers... You did a excellent job explaining everything. Sometimes when I read an article such as this the author looses me half way through. However, even with my very limited electronics experience I think I can build one of these! (Well, with the exception of the PICAXE microcontroller programing.... Unless I can just copy and paste lol. I read your first article on the PICAXE microcontrolers and saw it was designed so a child could program them. But unfortunately I'm feeling like my dad did when I tried to explain how to program his VCR years ago ). One of the things in your article that really helps me out a lot (and I learn from this) is to be able to see the actual physical circuit along with the schematic.
Capacitor C1 is for suppression of noise that might be on the power lead to the PICAXE; it's good practice to put a .1uF cap across the power leads of all integrated circuits.1.) What is the purpose of the capacitor?
2.) How many amps can this PICAXE micro controller handle?
3.) Are the C.1,C.2, C.3 etc. like dry contacts on a relay? I'm guessing no, but thinking it's something similar
Thanks so much for your help!
Thanks so much!Capacitor C1 is for suppression of noise that might be on the power lead to the PICAXE; it's good practice to put a .1uF cap across the power leads of all integrated circuits.
Each I/O of the PICAXE can handle about 20mA directly; to control larger currents, it is necessary to add an additional component or two such as a power MOSFET.
Each of the I/Os are capable of outputting a logic high or low on command; these signals are used either directly (within the constraints mentioned above) or indirectly (as also mentioned above.) So, they are not dry contacts but they may be used in much the same way.
