"Hi, I bought two small servo motors last month. I was thinking what I can do with this two servo, since it is only two in number. Then I asked this to my friend Achu Wilson and he suggested me to try a four legged two servo walker and he shown a youtube video in which some one demonstrating it. Then I also got interested to make some thing similar to that."

"I developed this WSN for a coursework on my MSc and I’m hoping others will find this useful or at least interesting 🙂 I’ve just installed the first parts of this WSN back home to collect sensor data from various outbuildings and it will be part of my new Arduino controlled greenhouse project."

"…At this moment the robot can measure its speed and regulate its motors to keep a desired speed. This means that when the robot goes uphill it will recognise that its speed has dropped and will increase motor power and vice versa when it goes downhill. The regulation is currently nothing more than: if speed is faster than desired then decrease motor power with a constant amount…."

"This project is a small LED matrix sign/display/badge intended as an SMD trainer…I designed this version from scratch to make it a bit bigger to allow the use of larger LED’s (easier to hand solder), and use a “better” microcontroller to allow more creative programming (in C)."

"One day a friend (who is also a Mechatronics engineer) and I decided to build an ultrasonic rangefinder. Sure, you can already buy modules such as the LV-EZ1 from Sparkfun, but where would the fun be in that? Moreover, things get expensive when you start wanting several of these sensors."

"This blog serves a narrow but illustrious audience: the photographically inclined electronics hobbyist. Yes folks, I’m going for the masses here:) Kidding aside, if the line above describes you, or even if it doesn’t but you find yourself having to illustrate an article here and there with an analog oscilloscope screenshot, then this article is for you."

"The Witness Camera is a combination of a VGA CMOS camera, a passive-infrared movement sensor, a 1 GB SD-card (or bigger), and an AVR Mega32 microcontroller implementing a solid-state time-lapse recorder. It is a compact, complete, self-contained surveillance system designed with home users in mind."

"The main incentive behind this project was to see how much I could cram, in terms of both hardware and software, into a wristwatch-like device that is no larger than the display itself. An OLED display was chosen for being only 1.5mm thick and not requiring a backlight, but mostly because they look cool. "

"An interesting project has come up as a fund-raiser for BuildBrighton members – to “hack” some alarm clocks and modify their behaviour so that instead of playing a single sample when the alarm sounds, one of up to seven different sounds can be played."

"Capacitors are one of the most common passive electrical components that are extensively used in all kinds of electronic circuits. In this project, we will discuss a technique of building a digital capacitance meter using a PIC microcontroller. This project can measure capacitance values from 1 nF to 99 uF, with a resolution of 1 nF."
