OpenMV Cam, Final Week

OpenMV Cam, 1.8" x 1.4", final week on Kickstarter
If you haven't heard of OpenMV Cam, it's a small machine vision module that's affordable, and the first that runs Python and is expandable with shields. It's funded and we're entering our final week on Kickstarter so don't miss out.

Wait. Python? Yes, it runs Micro Python on the module.

That means with some simple Python scripts, your project can detect and track a human face, or an object, or you can track multiple colored objects of different colors, you can take a picture, record movies, interface with UART, SPI, I2C, control servos and more.

For NoCo Mini-Maker Faire, I set up a demo with my red Magician robot rotating to track a yellow object (placed on my Pololu 3pi). I tweaked the color tracking script in a few minutes to output the blob coordinates over serial to the PIPduino controlling the Magician, then wrote the Arduino code in another few minutes to spin in place based on blob position. Then tuned the color matching, et voila:
