I just ran across this post today.· Phil, you've got my brain juices flowing again from when I used to work on this stuff in the Army.· The stuff I worked on was 1970s technology(still used today), so I am sure with the quality of parts we can have some real fun with this
I received an email requesting more info on this project. Here's what I used.
Hardware:
····BOE with BS2. ····Parallax thermal Senosr Module (#28040). ····Custom machined imaging disk (0.03" black paper phenolic). ····Miniature servo to turn the disk. ····Mounting plates (custom machined), fasteners, etc.
A DXF file for the disk and vertical mounting plate are included in the attached ZIP. The vertical mounting plate attaches to the BOE via 1/4" dia. standoffs and 3AG fuse holders, which clip onto the standoffs.
Software:
Attached below. There are two BASIC Stamp programs: one for snapping the picture, the other for dumping the data to the serial port. This data is then copied from the DEBUG screen and pasted to the end of the included Perl program to create the PNG image, a sample of which is included. 'Sorry about the lack of comments or other documentation. I'm on to other projects, and this is the best I've got time for right now.
If anyone has further quesitons, please ask them here, rather than via email.
The heat sensor is insensitive to sunlight (and even candle flames, I've discovered). Sources that incandesce in the visible region have a black body radiation spectrum whose wavelengths are too short to register with such a sensor, apparently.
Hi Phil, I continue to be amazed by all the cool stuff you build.
The insensitivity to sunlight or candle light is due to an integrated long pass filter.
From the manual: "An optical filter (long-wave pass) that cuts off the visible and near infra-red radiant flux is integrated in the
package to provide ambient and sunlight immunity. The wavelength pass band of this optical filter is from 5.5
till 14μm."
I'm glad this thread was reopened. This project was designed around a BS2. What could be done with a propeller? I once wanted to buy a flir camera but they are so expensive.
