I really doubt it… I’m in Cancun, Mexico and the delivery services here sucks (all brands, all carriers). I’ll let you know as soon as I got them in hand!

Cheers!

Can’t wait to see how it works, I’m in the US and I’m ordering them right now, it’s to cheap not to try it out myself.

As far as i could get 780 is near-IR , everywhere on the web it says that 780 is invisible to the human eye.And also , I’d prefer it to have a red glow when I touch the surface , Larky was right , it’s quite cool.

There is no red glow. It is a bit brighter than 850nm, but still very faint.

So does anybody know if 5mv modules will be sufficiently powerful? It’s not the price for the 10mv modules that bothers me, I just don’t want to blind anybody (or myself!). Alex, I believe you initially experimented with just one laser in your set up? Were the blobs bright enough? I’mm thinking that if one 10mv laser was sufficient then 2 x 5mw should work also…

I’m thinking about ordering a couple of these plus lenses to try out my own setup, most likely utilizing my (father’s) huge TV.  Something I saw on there was a nice power adapter.  I’m not very electrical savvy, so I thought I’d ask: would one of the power adapters be enough to power two lasers? Or should I have one per laser?

Here’s a link to it: Power Adapter

Can any all knowing members answer his question? wink

I’d like to order it, but I’d like to make sure to get an ok from the Pro’s here.

I’m certainly not one of the pros, but the specs listed for the 10mw laser modules says that they run off 3.2V DC. It does not give the rating in milliamps for the laser modules, but the power adapter outputs 3.2V @ 500 milliamps. Unfortunately, I believe this means you will need 1 adapter per laser module :-( You may however have some old mobile phone chargers lying around that could be put to the task. Of course be careful when doing this.

If you’re looking to step down the DC current from a power source higher than needed, you can buy a +3V or +5V voltage regulator from any RadioShack. Just wire it up to a small breadboard and you’re good to go. They can be used with DC sources up to +35V.

This is usefull for people that want to use the random wall warts they have lying around the garage, that are usually more than 3 or 5 volts.

Here’s a picture of mine, I’m stepping down a +9V wall wart to ~+5V.
