Ultraviolet Business Card Flashlight

Step 2 The artwork

First of all, design your artwork - getting this looking good can make the cards look really professional.  Use whatever graphics package you're familiar with - "Inkscape" is a good open source package, or you might already have Microsoft Publisher.  You'll want to design them around standard credit card dimensions (85.6mm x 53.98m or 3.370" × 2.125") but you'll also want to make them just a bit bigger on all sides (called a bleed) - I made mine 92mm x 60mm).

You will probably want to print some sort of icon for the switch (around 20mm in diameter) towards one end of the card - mine looks like a light bulb.  This is really just a part of the card which will be pushed to turn it on (you will see later how this works - it will align with the battery which is in a circular cutout in the foam behind this).

Then print them out, and cut them roughly around the border (they should still be over-sized).  Depending on your inkjet, you might want to spray a clear protective inkjet varnish over the printout before the next step if you want them to be really long-lasting.

Lasertag cards? Nice! That would be an awesome giftcard to a lasertag business. The giftcard should have a small laser. I've seen some 3mW red laser modules on ebay that had the lens cast in place around the diode, so it's a really small package. No link, sorry.

where and how do you contact a "Professional"?

If you are piggy backing off someone else's cool contribution to the Maker community it would be a 'Nice' thing to refer to your own helpful 'Instructable' which shares additional experience and fun. Many curious Makers will find that these cool things are fun but, when doing for our own businesses they will distract from our bread and butter. What does this mean? People will hire a professional but, likely not one taking from someone else's contributions.....
