This page will host instructions on assembling and using the infrared/visible dual camera kit as distributed through the Balloon Mapping Kit Kickstarter project.

This page is under construction and will not be complete until mappers report their early experiences with the equipment. Please get in touch on the mailing list if you want to contribute your knowledge here.

Introduction

• How this works, why we do it -- theory and science
• What it's useful for (applications, case studies)
• How far we've gotten
• Things to try and/or improve (how/where to contribute)

Construction

• The dual camera rig: Assemble the camera bracket
  • Putting the T rig inside a big soda bottle, or other techniques to protect the cameras.
  • Attaching the timer and batteries.
  • Use the camera strap as a safety landyard.
• Simple shutter release: Trigger the cameras with rubber bands
• Hardware for synchronous shutter release: Assemble the electronics
  • Assembling the 555 timer circuit
  • Preparing USB cables
  • Preparing batteries and battery holders
• Enhanced firmware to enable USB triggering and synchronous shutter release
  • Install and configure CHDK

Using your kit

• Using the Canon A495 cameras: Configuring the camera menus
• Do a test flight

Processing the images

• Link to Photoshop/Gimp technique
• Video screencast of MapKnitter technique
• Brainstorm better techniques

Interpretation

• This will be written last

Attached is the "introduction" document which shipped with each kit (also editable in Google Docs). For help, please contact the mailing list -- either register on Public Laboratory or email publiclaboratory@googlegroups.com.
