After a year or so of reading and drooling over other people’s wonderful projects in these pages I decided to finally make one of my own. Here is my first instructable, a version of the ever popular Battery Desulfator, which I built in an Altoids tin. First, some background: My urge to build this project […]

A little bigger than a postage stamp, the Simple Servo Tester lets you control two digital or analog servos without using a transmitter or receiver, just plug in your battery pack to start testing. Use it to check your servos before installing them into your models or to center your servos when setting up linkages. […]

Sleep modes and idle modes in general-purpose microcontrollers have allowed embedded processors to reduce real-time energy consumption and tackle many battery- and low-powered designs. However, as embedded systems become increasingly complex, it takes additional logic to implement a denser, more sophisticated micro core as well as the higher-end peripherals we expect to see today. As […]

PoE – Power over Ethernet is already a common is already a common matter. With the Ag5200 module you too can use this functionality and eliminate a mains adapter. A thought to use an Ethernet cable even for a power supply is already known for many years. To use an existing data connection even for […]

Researchers at the San Diego Supercomputer Center at the University of California, San Diego, have developed software that greatly expands the types of multi-scale QM/MM (mixed quantum and molecular mechanical) simulations of complex chemical systems that scientists can use to design new drugs, better chemicals, or improved enzymes for biofuels production.

Baylor University researchers, in collaboration with an international team of scientists, have discovered definitive evidence of the environment inhabited by the early ape Proconsul on Rusinga Island, Kenya. The groundbreaking discovery provides additional information that will help scientists understand and interpret the connection between habitat preferences and the early diversification of the ape-human lineage.

I’ve started to build a little FM radio with one of this cheap modules with a Phillip chip, the TEA5767. I will control it with a MSP430, probably I’ll use some kind of encoder to change stations and a potentiometer for the volume. The TEA5767 is a single-chip electronically tuned FM stereo radio for low-voltage applications […]

(Phys.org) —Self-replicating malware has struck some older Linksys routers and Linksys has acknowledged awareness of the malware, called “TheMoon.” They plan to make firmware fixes for all affected products available “Linksys will be working on the affected products with a firmware fix that is planned to be posted on our website in the coming weeks,” according to a company statement. Only those routers with Remote Management Access enabled within the administrative settings are vulnerable

This wearable LED heart simulator pendant was inspired by my work as a cardiovascular surgical nurse as well as my love of electronics.  It simulates the electrical activity of 17 different rhythms and when paired with the heart backplane, it becomes an audio and pulse simulator as well.   It is not so much a […]

Introduction Imagine a marathon on a very hot, dusty day when saving every ounce of energy matters to the outcome. This race isn’t half over, but the winner seems certain. The lead looks insurmountable, because this runner can do more with less energy. This runner shines brighter. In the face of heat and competition, this […]
