The traveling exhibit

So that's the traveling exhibit. Marcy 2 underwent 2 board designs to support 2 different cameras. After 3 days fighting it, the TCM8240 finally won & no picture could be gotten from it. There wasn't enough documentation to get either JPEG or RAW.

There was a brief fascination with getting the TCM8240 to work in any RAW mode, once JPEG was proven unworkable, but without JPEG, it's absolutely worthless & too heavy to justify buying any more of.

In 1280x1024 mode, the scan rate would be so slow, it could only photograph stationary objects. No-one is going to invest in an SRAM if cheap spycams can get higher resolution. Finally, the TCM8240 overheated the power supply.

With single layer home made etching, the TCM8240 board can't be reconfigured at all to use the TCM8230. Rerouting is only feasible with the arrangement on the TCM8230 board. It needs to get a lot bigger to support sonar.

If the TCM8240 worked, it would have been a wifi video downlink from the Blade CX. It would have been neat, but the Blade CX is going to a customer, never to be seen again.

It got me thinking the monocopter is extremely limited. It could only be used for low resolution still photos, but nothing useful. The neatness of 4fps video from a spinning wing quickly fades when considering the usefulness of video from a stationary copter. Something that automatically follows your face would be useful for a low end video blog.

Both platforms are aerial, so always very shaky compared to a ground based camera robot, but still ahead of most content. Anything aerial would be better suited to still photos. Part of the motivation to fight for shaky, low res video on a copter that's going away, with a camera that's going away, was to keep the $60 spent on those from being a mistake.
