Password Based Circuit Breaker

Electrical accidents are rapidly increasing especially electric line repairs incident due to the lack of communication and coordination between the maintenance personnel and the electric substation staff. The password based circuit breaker device could just be the solution as only the lineman could reliably control the circuit breaker to avoid miscommunication. The system requires a password to turn ON/OFF ...

Things heat up for self-destructing electronic devices

Expanding on previous research into electronic devices that dissolve in water once they have reached the end of their useful life, researchers at the University of Illinois have developed a new type of "transient" electronic device that self-destructs in response to heat exposure. The work is aimed at making it easy for materials from devices that usually end up in landfill to be recycled or dissolved compl ...

Compensation of Oscilloscope Probes

sing simple wires to measure signals with the oscilloscope would result in unreadable plots on the scope, the main reason being the noise coupled onto the “probe” itself. The first line of defense against that would be to use a coaxial cable as a probe, which would prevent external noise coupling. 1. Introduction An unwanted deterioration of the measured signal is due to the capacitive loading that such a p ...

Unlock a Door with your Fingerprint

We built a biometric fingerprint-controlled lock prototype. A fingerprint scanner is used to capture and store the fingerprints of authorized users. When the scanner recognizes a user, a solenoid plunger disengages and opens the lock.Parts List: The fingerprint scanner module is powered by an ARM Cortex M3 CPU, which controls the on-board optical sensor and fingerprint recognition. Fingerprints are stored a ...

Tiny DDS – Open source DDS generator

Description The homemade function generator is a quite common project on the internet. We can find different ways to do it: - The quick & dirty way based on a DDS module bought on eBay - The analog version based on a MAX038 / XR2206 - The “clean” way based on a FPGA and a fast DAC (e.g. http://www.circuitben.net/node/14) - The software way (e.g. Arduino + R/2R DAC) From my side, I wanted a small one whi ...

Large Current Relay Driver

This is a large current Relay module with single pole double throw switch which provides normally closed and normally open operations. The Relay is the most common used module in application such as home automation, industrial automation, and machine on/off. Sometimes you need to control large current such as the fans, lights, water heaters, room heaters, Air-conditioning, vacuum pumps That is what this Lar ...

Passive Infrared Detector Circuit

The infrared (IR) is invisible radiant energy, electromagnetic radiation that we cannot see with our eyes, but we can sometimes feel on our skin as heat. The infrared light falls just outside the visible spectrum, beyond the edge of what we can see as red. Most of the thermal radiation emitted by objects near room temperature is infrared. The circuit uses a MCP6032 microchip operational amplifier. The MCP60 ...

Find the right solder for you

The solder matters, it is an undisputable fact confirmed daily in a development and production of electronics. Hand soldering of prototypes, automated machine soldering, soldering of small SMT components or on the in contrast soldering of big joints of massive connectors, rework, … all that wants a solder optimized for a given usage. As we know, features of a solder wire are determined by an alloy itself (P ...
