Picture of Laser Pumpkin
This is a quick tutorial showing how you can create a Laser Pumpkin.

The idea for this project came from last year's article entitled "Jack-O-Laser of Doom" which involved creating a Jack-O-Lantern with a Laser Vortex projecting from the mouth and eyes. Our pumpkin was very similar, but instead we used a couple of our laser accessories to create a unique Jack-O-Lantern. This project would be great for parties and dance clubs, as well as your front porch.

The equipment you will need will be a laser with continuous operation, diffraction gratings, a pumpkin, and something that will create fog or smoke.

Step 1: Carve a Jack-O-Lantern

Everyone knows how to do this step, it's easy. Scoop out your pumpkin guts, and carve out a scary face. Keep in mind when designing your Jack-O-Lantern how you would like the laser beams to project out of the eyes, nose and mouth. The best pumpkins for this will have large mouths and eyes.

This is neat! We're going to have to try this with our laser cut pumpkins this year! Laser cut pumpkins with laser lights... Lasers everywhere!

Where can I cheaply get a laser that can produce a visible beam? Can I somehow overpower a regular laser pointer to achieve a visible beam? Are there any cheap devices such as wall alignment tools that I can get and then extract a laser out of? Please help.

just blow some smoke, cheap smoke machines can be found online, but you can also buy some dry-ice and put it in a bowl of hot water

I would do that if I were more interested in a Halloween effect, but right now, I'm bent on getting a laser that can at least project a dot that can be easily visible in moderate daylight, or a laser that projects a visible beam...
If you're not in the US or Australia, http://www.dealextreme.com/details.dx/sku.469~r.25675451 will be perfect. Cheap as nuts too.
Visible dot in daylight, visible beam at night. It's great. I've had several (bought more for friends). And DX is indeed a good reputable site - lotsa great stuff, and they're great on returns if it's needed.
Totally agreed. I bought a 30mW laser and 100 magnets from them, perfect.

WOW I was super surprised when I looked at all of the optics at NovaLasers! Most sites only have a couple diffraction gratings and usually charge an arm and a leg... Great Instructable!! Really cool idea!

Two words: DANCE PARTY!!!
Shoop Da Whoop.
Great idea, great instructable. I was wondering if you were to put mirrors on the sides of the pumpkin wouldn't you generate greater defraction..

This is major cool! Wondering the same thing as billbob though ... how powerful is the laser you used?

For this project I think the green was around 20mW, the red was only a 5mW and the blue was a 50mW. But we didn't put the power ranges in this Instructable simply because power is not a major concern for this project, you can use very low powered lasers and it will still look amazing. But for all the laser fans out there, I know you guys like to know the power outputs, so I apologize for leaving them out. :)
I tried this with a 125 mW green laser! :D It looked SO cool! but stupidly I kinda forgot about my neighbors who got all freaked out because they saw a bunch of little green dots on their wall.
Cool, nice to know... Awesome instructable
Blue lasers? That's some pretty expensive tech inside that pumpkin... blueray technology costs thousands of dollars, even for a low-power stationary laser.
its green ray!

if you need a blue-ray prep a ps3 for organ doring see my post http://www.instructables.com/id/organ-donor-ing-in---eletcric-stuff!/

Coolest pumpkin I've ever seen.

We had to dispose on the pumpkin. Luckily for all you explosion fans, it went out with a bang. Watch the video.

Novalasers FTW! I buy from them. :D never had an under spec laser! always ~5 to 10mW over!
