See the new sign and blue light in upper right. (Photos: J. Maus/BikePortland) PBOT has been trying to educate bicycle riders how to get green lights for a long time now. I spotted their latest effort ...

[KLOZ] submitted his final project from college. Rather than an expensive CCD camera, he used a set of colored resistors LEDs and a light dependent resistor (I’m assuming he means a photo resistor) to ...

Color vision, ocular color detection is achieved with complicated neural mechanisms in the eyes. Researchers have found color detection with a simplest mechanism in the fish pineal organ, an ...

Using the lamprey, researchers analyzed the photosensory mechanism of the pineal organ, also called the pineal gland, in non-mammalian vertebrates and discovered a novel mechanism of pineal color ...

The student projects that come out of [Bruce Land]’s microcontroller- and FPGA-programming classes feature here a lot, simple because some of them are amazing, but also because each project is a ...
