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.

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!

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.
damasta says: Oct 7, 2008. 12:49 PM
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
Xellers says: Oct 18, 2008. 11:44 AM
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.
Tommyhzy says: Aug 8, 2009. 3:23 PM
Totally agreed. I bought a 30mW laser and 100 magnets from them, perfect.

Shoop Da Whoop.
CarolineTigeress says: Jul 24, 2008. 9:30 PM
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..
Matt D655 says: Jul 17, 2008. 12:39 PM
thats viscious.
npsark says: Mar 7, 2008. 1:01 PM
Amazing!! finally something useful i can do with my laser!!
mever says: Nov 8, 2007. 2:13 PM
This is major cool! Wondering the same thing as billbob though ... how powerful is the laser you used?
novalasers (author) says: Nov 9, 2007. 7:18 AM
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.
mever says: Nov 9, 2007. 3:18 PM
Cool, nice to know... Awesome instructable
hamishofangus says: Dec 6, 2007. 10:17 PM
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.
novalasers (author) says: Nov 9, 2007. 7:22 AM
We had to dispose on the pumpkin. Luckily for all you explosion fans, it went out with a bang. Watch the video.
BlueFusion says: Nov 8, 2007. 2:48 PM
Novalasers FTW! I buy from them. :D never had an under spec laser! always ~5 to 10mW over!
gwrober says: Nov 8, 2007. 2:20 PM
Very, very, cool!
X_D_3_M_1 says: Nov 7, 2007. 11:30 AM
