Motorized Pulldown Curtain (Phone & Radio Controlled)

https://youtu.be/v0-TlGm9BxM I pull my curtain up and down a couple of times a day. If I watch a movie I pull it down and then, I pull it up to get better lighting. I also pull it down when I go to sleep and I pull it up again when I wake up. I want this process to be automatic, if my curtain rises before I wake up, it will be easier for me to wake up when the clock goes off. Just like those night lights th ...

30 Minutes HIV Detection Using USB Stick

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 read by a computer, laptop or handheld device. We have taken the job done by equipment the size of a large photocopier, and shru ...

Arduino Sprinkler Valves + Wifi + Twitter

This is my first post so... be brutal ! I have a small yard with a very odd shape, well... L-shaped really and not enough pressure at the tap to be able to water it in one go. So I had to create 3 sprinkler sub systems that can only be turned on one at a time. I sourced 3 Gardena valves but refused to cough up the extra cash for their dull 'computer' (not sure why they call it a computer btw). Besides, cont ...

These tiny batteries can be charged in seconds and last for a week

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 are searching for a way to make a battery that’s tiny yet capable of holding the charge for a long time. So, what’s the so ...

Simple Audio Amplifier

In most cases first project in electronics for beginners is building simple audio amplifier. That is because it requires small number of elements and not a lot of knowledge to build one. For low power amplifiers we could use integrated circuits like TDA family. But I will show how to make amplifier using operational amplifier. This amplifier is only to proof the concept. It real use can be as preamp for gui ...

Use Arduino Code on a TI Launchpad MSP430

You can now use Arduino sketches to program your TI Launchpad MSP430. The video show me programming an Arduino Mega 2560 and a TI Launchpad MSP430 with the same Arduino sketch. https://youtu.be/-KKmkwHapSw The TI Launchpad MSP430 is a microprocessor development board from Texas Instruments.  It's very similar to the Atmel chips in the Arduino.  The MSP430 2553, which is the processor that ships wi ...

Build the World’s Smallest Atomic Clock

For Fridtjof Nansen, 13 April 1895 started well. Six days earlier, the Norwegian explorer had set a new record for the closest approach to the North Pole, and now he was moving quickly over unbroken sea ice toward Cape Fligely and home. But then came a sickening realization: In his eagerness to break camp, he had forgotten to wind the chronometers. He had lost track of precise time, and thus the ability to ...

PNP Transistor – How Does It Work?

The PNP transistor is a mystery to many. But it doesn’t have to be. If you want to design circuits with transistors, it’s really worth knowing about this type of transistor. For example: Want to automatically turn on a light when it gets dark? The PNP transistor will make this easy for you. In my article how transistors work, I explained how a standard NPN transistor works. If you haven’t already, I’d reall ...
