Flash Destroyer is a device that writes and verify an EEPROM  memory until it fails. According to manufacters a flash memory can be written a million times. This device is going to verify this pushing flash memory to it’s limits. The times the memory is written is displayed on 7-segment LED displays. [via]

Located in a cave more than a mile underground in Canada, SNO can be thought of as a type of telescope, though it bears little resemblance to the image most people associate with that word. It consists of an 18-meters-in-diameter stainless steel geodesic sphere inside of which is an acrylic vessel filled with 1000 tons of heavy water (deuterium oxide or D2O).

Attached to the sphere are 9,522 ultra-sensitive light-sensors called photomultiplier tubes. When neutrinos passing through the heavy water interact with deuterium nuclei, flashes of light, called Cerenkov radiation, are emitted. The photomultiplier tubes detect these light flashes and convert them into electronic signals that scientists can analyze for the presence of all three types of neutrinos.

uOLED-32028-P1T is an Active Matrix OLED Module with Touch screen sized at 2.83″. OLED screen is controlled by a PICASO-GFX graphics controller using code that runs on host controller or by serial commands send by an external microcontroller. In that way it can be a stand-alone add-on to any project. In this article learn how to quick start using this module.
