The GrassrootsMapping wiki details how to put together a balloon-powered aerial photography kit with about $40 and some elbow grease.
Here’s what you need to put together this weekend project:
- A balloon or even a giant trash bag
- Helium
- Long String
- Camera Mount: Crafted from scraps or a drink bottle
- Camera (even a cameraphone will work)
Your camera must be able to take photos at a regular interval. CHDK, which we’ve walked through setting up in the past, is a great firmware replacement that adds loads of useful features (including interval photos) if you have an old Canon laying around that you are willing to fool around.
After your balloon has returned to earth, you can use the Cartagen Knitter to sync up your photos into a large photo.
For full instructions, check out the Grassroots Mapping wiki, and make sure you are following any local rules and regulations regarding balloons. If you give it a try, share any photos of your project below and offer any tips you might have for our other readers! Photo remixed from nadya.
