NEW FLEXIBLE RECHARGEABLE SILVER OXIDE-ZINC BATTERY 10 TIMES STRONGER THAN LITHIUM BATTERIES

NEW FLEXIBLE RECHARGEABLE SILVER OXIDE-ZINC BATTERY 10 TIMES STRONGER THAN LITHIUM BATTERIES

A team of researchers made up from the University of California San Diego and California-based company ZPower have developed a flexible, rechargeable silver oxide-zinc battery with a 5 to 10 times greater energy density than standard batteries. A good characteristic of the battery is that it is easier to manufacture because most flexible batteries need to be manufactured in sterile conditions, under vacuum, …

Image Plotter

Image Plotter

Introduction Our ECE 4760 final project was an image plotting system with high-level processing done in a MATLAB script we wrote and the low-level control software done on the PIC32MX250F128B microprocessor. Our MATLAB program takes images and extracts endpoints of line segments and sends the coordinates over to the PIC32 via UART serial communication. The …

600W STEP-UP BOOST CONVERTER (12 – 60 V 10 A) WITH ADJUSTABLE VOLTAGE AND CURRENT

600W STEP-UP BOOST CONVERTER (12 – 60 V 10 A) WITH ADJUSTABLE VOLTAGE AND CURRENT

As a maker, we are always looking for the best way to power our projects. Usually, buck and boost converters are a considerable part of our project, because without good power, then everything else can be compromised. As important as it is, one does not want to splurge huge amounts of money on something that …

STRETCHABLE CONDUCTORS MAINTAIN CONDUCTIVITY UNDER 700% STRAIN

STRETCHABLE CONDUCTORS MAINTAIN CONDUCTIVITY UNDER 700% STRAIN

Conductive materials change their properties under strain or stretching. The electrical conductivity decreases and resistance increases with stretching. The US Air Force Research Laboratory (AFRL) is working with liquid metal systems that can autonomously change the structure to become better conductors in response to strain. Polymerized Liquid Metal Networks, the material developed by AFRL scientists, can show …

TEXAS INSTRUMENTS TMAG5124 HALL-EFFECT SWITCH SENSOR

TEXAS INSTRUMENTS TMAG5124 HALL-EFFECT SWITCH SENSOR

Texas Instruments TMAG5124 Hall-Effect Switch Sensor is a high-precision Hall effect sensor that offers a 2-wire interface designed for industrial designs. The TMAG5124 integrates a current source that switches between two levels depending on the value of the magnetic field applied to the part. While the high value is fixed, the low value can be selected from two ranges. …

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 …
