"Interestingly the resistance of the material decreases when bent, implying that the electrical connections are being broken in the material because it is being stretched or damaged. When pressured the resistance through the material decreases."

"I have decided to create and document the design of a simple PID velocity DC motor controller. While this idea is not new or novel I feel that many people can take what I have learned from this project and implement it into their own designs."

"ArduCopter is an easy to set up and easy to fly platform for multirotors and helicopters. Its features go far beyond the basic manual control RC multicopters on the market today."

"This post shows how you can output VGA signals to a monitor, turning your Uno (or similar) processor into a ‘video card’."

This project is very similar to our own Arduino VGA output but much more comprehensive — including assembly code!

"I have been searching for ideas of making a Quadcopter Arduino flight controller Adapter to sit my Arduino nano board and the GY80, also have some header pins for motors and receiver to make the cabling tidy. There are a lot of Arduino shields people have designed for the Quadcopter. I didn’t follow any of the designs. I actually didn’t follow any planned design and solder the parts on the veroboard as I go along."

Now for a really fun lesson in our PyroEDU’s Analog Electronics course! This week we dive into Active filter circuits. Here’s a quick intro of what this PyroEDU lesson is all about:

This type of analog filter is one that utilizes op-amps which can make sure the input signal is the same strength as the output signal. In this lesson we will build an active band-pass filter and see the effect it has on an audio signal when we vary its parameters.

"A geekish clock using a single 8-pin AVR microcontroller that tells the time with LEDs in binary for each decimal digit, much like the famous ones from ThinkGeek, but with some exclusive features such as couting in Gray code."

"The circuit was build with microcontroller ATmega8.
Here, I’m extending the same circuit to control the DC motor with IR remote control. The motor is fitted on a toy car wheels with gears, as shown in the figure above."

"The 2009 Robot Rally spotlighted all the flaws that result from a quick 3 week engineering and building project. Time saving shortcuts in code and hardware bit my butt several times. Failed edge detectors – Ouch! Failed beacon tracker … chomp! Ow! Line follower reversal – Arrrg! I’m happy to report I’ve investigated all the issues that cropped up and fixed them all."

"A modern microcontroller has almost everything that’s needed to implement a touch sensor matrix. There are several sensing technologies: IC manufacturers typically advise using certain tech, sometimes they offer ready to use hardware- or software-based solutions. I was curious to try to implement a sensor matrix entirely from scratch all by myself."
