  • As a musician and designer of gesture-based musical instruments, I'm very interested in this product. My previous designs have employed passive photocells, and, most recently, the Sharp family of IR sensors. The Sharp sensors work in a similar manner to these, and although they are cheaper, they are slower and do not detect left-right position and motion.

    One big question in regard to using multiple units is: how much cross-talk will there be when more than one unit is positioned in close proximity? Or, put another way, how far do the units have to be apart to eliminate cross-talk?

    It would be great if SparkFun or XYZ could provide some guidelines on the issue.

  • Can you please post the actual dimensions of the board? A photo of the board next to a quarter on its side gives a general idea, though not as good as your usual method of depicting devices next to a ruler. Neither, however, is quite so accurate (nor so easy to list) as the actual dimensions. If one has these, the photos are superfluous.

  • This is a great product, except (in my opinion/experience) for one "fatal" oversight: the lack of a power on/off switch. In the past couple of years, I've worked with several products that use the same batteries and connector, but also omit a switch. Therefore, the only option to reserve power when not in use (other than running in low-power mode on the processor---a requirement in some applications and impossible in others) is to unplug the battery. And that is not an easy task, given the almost glue-like grip of the JST connector. You either must use a tool (though you will need to adapt, as there is no tool specifically designed for this purpose), or expect to have a few broken fingernails.

  • To be more specific: I want to create a stack with the Edison on top, the 9DOF board in the middle, and the battery module on bottom. Will I be able to do this without any additions or modifications to any of the boards?

  • In the image shown for the battery module, the stacking connector is not present on the board. Is this an oversight, or will users be required to add the connector themselves (a capability not within the ability of most users)? Also, do all the SparkFun Edison modules include connectors on both top and bottom for stacking?

No public wish lists :(
