Why wax poetic:

It's a glow in the dark board. You can draw on it with lasers.

It is like a remote self-erasing Etch A Sketch.

Step 1: Parts

Step 2: Build

Cut the tape into strips. Put the strips on a board or wall or anything; it doesn't really matter.

Step 3: Draw

For tight clean lines hold the laser against the board and draw on it like you would with a pen. It can also be drawn on from across the room, but the lines are all squiggly.

The second video shows a prototype, where I used two different brands of glow tape with two different half-lives. This is what causes the stripe pattern.

<p>This is great! I am trying to order a UV laser online but can't tell if it needs to be an actual UV laser which seems to be pretty expensive, or just a violet colored laser which is quite affordable. any help?</p>
awesome! I was expecting something complicated but this is totally doable! good job!
<p>AWESSOOMMEE!!! I would love to make it but I don't have a uv laser point *sniff*. Anyway Great Job !! :)</p>
<p>Look on ebay. I got a pack of 3 (red/green/blue) for like $9 shipped. The blue is actually more of a uv color and lights up highlighters like a black light!</p>
Awesome! Thanks for sharing!
