In many parts of the world leaving open a door or window is a good way to get a house full of bugs. Remembering to close doors behind them can be surprisingly hard for members of the human race, so the [DuctTape Mechanic] used the components from a car’s electric window to automate his sliding screen […]

It’s often taken for grated, but the modern world is full of luxuries. Home automation, grocery delivery, and even access to the Internet are great tools to have at hand, but are trivial to most of us. If these modern wonders are not enough for you, and the lap of luxury is still missing a

COLOUR SENSOR Previously I have made a colour sensor using Arduino but don’t have the time to update it on my blog. Today I am going to share the details of this mini project. Basically, the sensor consists of three LEDs and Light Dependent Resistor (LDR). The LDR will detect the colour and display it

March 20, 2014 – University of Utah electrical engineers fabricated the smallest plasma transistors that can withstand high temperatures and ionizing radiation found in a nuclear reactor. Such transistors someday might enable smartphones that take and collect medical X-rays on a battlefield, and devices to measure air quality in real time. “These plasma-based electronics can

Have you ever been at the bookstore and stumbled across a great book you’ve been looking for, but had a nagging feeling that you already had it sitting at home? Yeah, us too. If only we’d had something like [Kutluhan Aktar]’s ISBN verifier the last time that happened to say for sure whether we already had

On the face of it, making a clock that displays the time by moving a pointer along a linear scale shouldn’t be too hard. After all, steppers and linear drives should do the job in a jiffy. Throw an Arduino in and Bob’s your uncle, right? Wrong. At least that’s not the way [Leo Fernekes]
LINEAR CLOCK RATCHETS UP THE ACTION Continue Reading
Very often, particularly on the Internet, we’re fooled into thinking bigger is always better. The fact remains that this isn’t always the case. When it comes to reflow ovens, for example if you’re working with short runs of small PCBs, or if you just don’t have a lot of space in the workshop, a smaller

If you think about building a moving machine, you probably will consider wheels or tracks or maybe even a prop to take you airborne. When [nwlauer] found an earthworm in the garden, it inspired a 3D-printed robot that employs peristaltic motion. You can see a video of it moving, below. The robot uses pneumatics and soft plastic,

Most of us reach for an over-the-counter medicine if we have occasional pain, but menopause doesn’t act like that. Hot flashes don’t build like a headache, dizzy spells don’t wait for a good time, and panic attacks don’t announce themselves. Predicting and addressing sudden hormone shifts is the intent behind Menesto, a vest with sensors, cooling apparatus,
