Things you will need in order to complete this instructable:
- A small pumpkin (mine was about 6" in diameter)
- Access to a 60 watt laser cutter (you can use the laser cutters at TechShop!)
- Corel Draw or Adobe Illustrator (TechShop has this software installed for members to use)
- A bit of creativity
Step 1: Hold Your Pumpkin Steady
Step 2: Create Your Laser File
You can't have an image that is too big because the laser will go out of focus as it gets to deeper or shallower parts of the pumpkin. For a 6" diameter pumpkin I found that a 2"x3" image was a good size to minimize the effects of the laser going out of focus.
To find the TechShop logo, I simply did a Google search for "TechShop logo."
If you don't know how to use Corel Draw, TechShop can teach you some of the basics in the "Laser Cutting and Etching SBU", here is the link to sign up: http://www.techshop.ws/take_classes.html?storeId=1&categoryId=10
Step 3: Laser Etching Time!
Now it is time to enter your power settings, mine were as follows:
- Power: 60% (on most 60 watt laser cutters this would translate to 90% power)
- Speed: 25% (if you go any faster than this the etching will not be deep enough and your pumpkin might start to shake)
- Resolution: 600dpi
- Image dithering: standard
