This forum has lots of ideas and I need some help, please. We've got a lot of excess inventory at Parallax - it accumulates every time we obsolete a product.
We have about 1,200 Sharp short-range reflective photointerrupters (GP2A25J0000F) and 3-pin cables that accompany. These were used as our ActivityBot encoders before we got the Feedback 360 servo. I'd like to put these in a bag as sets of four, maybe with 10K (or 20K) resistors, the cables, maybe some jumpers and try to liquidate them. Probably have about $5-6K worth of parts.
A quick grab of data from Karlson Robotics:
Description: GP2A25J0000F Series are OPIC output, reflective photointerrupters with emitter and detector facing the same direction in a molding that provides non-contact sensing. This family of devices uses light modulation to reduce the affects of disturbing light, and the sensor is optimized to work in the selected focal distance. A 3-pin connector is included to allow remote-mount or off-board designs.
Reflective with OPIC Light Modulated Output
Includes additional screw fi xing holes
Position pin to prevent mis-alignment
Short focal distance
Detecting distance : 1 to 9mm (White paper) 3 to 7mm (Black paper)
Undetecting distance : over 27mm (White paper)
What kind of super simple project could be done?
If we had a four-pack of these available for sale on-line for $10, what kind of very simple project could be made with them? I could imagine them being lined up for a 4-bit piano if there was a speaker, or used as an edge detector for a robot. . .or even just provide a sample piece of code. If we sell them, it would be nice to show people what to do with them, but it's also not necessary.
Are there any simple applications that you might have in mind, even if we just offered an "idea list"?
Apologies for the cruddy pics - quickly snapped by a co-worker!
