The Outlet Nanny

The Outlet Nanny

We designed a power monitor that could communicate with the PIC32 through UART to give both power and current readings for any device(s) (that use NEMA plugs) plugged into our box. These readings are then accessible on a website interface, on a graph. We chose to do this project because of the growing issue of …

TFTanks

TFTanks

Introduction TFTanks is a two player game in which small artillery tanks shoot projectile shells at each other across the TFT display screen. The game board consists of a randomly generated terrain landscape with sharp hills and valleys that players can destroy incrementally with their shells. The game is turn based, where players use sliders …

NEW STUDY SHOWS RARE FORM OF MAGNETIC AND ELECTRICAL PROPERTY IN STACK-TWISTED GRAPHENE

NEW STUDY SHOWS RARE FORM OF MAGNETIC AND ELECTRICAL PROPERTY IN STACK-TWISTED GRAPHENE

A group of scientists at Columbia University and the University of Washington has found unique electronic states along with an uncommon kind of magnetism, can develop in a three-layer graphene structure. The work was inspired by current research studies of twisted monolayers or twisted bilayers of graphene, making up either 2 or 4 overall sheets. These results were discovered to treat …

Sunrise Alarm Clock

Introduction This report covers the design and building of a programmable alarm clock that uses a full spectrum LED to wake you up using your body’s natural response to sunlight. Rather than waking you up with an annoying alarm, a sunrise alarm clock slowly turns on a light in your room over the course of …

VISHAY INTERTECHNOLOGY AUTOMOTIVE GRADE PIN PHOTODIODES FEATURE LOW 0.7 MM PROFILE, INCREASED SIGNAL TO NOISE RATIO

VISHAY INTERTECHNOLOGY AUTOMOTIVE GRADE PIN PHOTODIODES FEATURE LOW 0.7 MM PROFILE, INCREASED SIGNAL TO NOISE RATIO

Vishay Intertechnology introduced two new surface-mount Automotive Grade silicon PIN photodiodes in the compact 0805 case size with a low 0.7 mm profile — 0.15 mm lower than previous-generation devices. Offered in black packages, the opaque sidewalls of the Vishay Semiconductors VEMD4010X01 and VEMD4110X01 eliminate unwanted side illumination to increase their signal to noise ratio. The AEC-Q101 qualified photodiodes are optimized for …

1A OVER CURRENT PROTECTION LOAD SWITCH

1A OVER CURRENT PROTECTION LOAD SWITCH

The Over-current limit load switch project presented here provides full protection to devices and loads from access load conditions. The default current limit is set to 1 Amp, however, this load limit is adjustable from 0.4A to 2A with the help of R4 ISET resistor. When an overload condition occurs circuit responds to that overload condition that lasts longer than …
