Battery anxiety is a modern day problem for many of us. Mobile phone and wearable technologies are getting developed rapidly, but battery issues seem to be neverending. As phones and wearables are getting thinner, there needs to be a trade-off between battery life and design. Scientists...

In partnership with DNA Electronics,  Imperial College London researchers had developed a revolutionary USB stick that can detect HIV in the bloodstream. In order to detect the virus, it’s enough to use a drop of blood. Then the USB stick generates an electrical signal that can be...

Tiny Bar-Graph display provide a Red color, bright, easy to read display which is proportional to the force applied on the FLEX sensor surface.  This Bar-Graph has 20 segments in single color and display Force applied on FLEX sensor. The Barograph force monitor is based on PIC...

When you are waiting for a very important letter to come, it's really bothersome to go and check the post box again and again. The problem gets worse when you are not at home and anxiously thinking if the letter arrived or not. Well, now IoT or Internet Of Things is your...

David Johnson-Davies designed a minimalist ATtiny85-based watch using 12 LEDs, arranged like a clock face, to show the time in analogue-style. He writes: To show the time you press the button on the watch face, and the time is then displayed for four seconds. It lights one LED to...

The PCB Rax is an easy to use, versatile printed circuit board holder for repair, prototyping , and assembly that can hold nearly any shape of circuit board. Check the details on the link below. Not all circuit boards are rectangular. PCB Rax was designed to hold all kinds of...

Susanne Nell @ edn.com has a design idea on how to measure high dc currents. To measure high levels of direct current for overload detection and protection, designers frequently use either a current-shunt resistor or a toroidal core and Hall-effect magnetic-field sensor. Both methods...
