“A good friend of mine, Corey, who lives on the other side of the pond (the US) asked me if I wanted to help building a Mikrokopter Octocopter kit he recently purchased. I accepted right away. It’s not every day you get to build a 2000 dollar multi-rotor platform and compare it to your own 100 dollar platform.”

“This is an SMS controller using a PIC16F688. Why a PIC16F688? Well for one, I have this in my parts bin and second of all, it is like an LF series part number operating from 2.0V up to 5.5V. I am using this on a Nokia mobile phone where the voltage level is around 2.7V. But it can also be used directly on GSM modems. This SMS controller utilizes textmode AT commands as the communication protocol.”

“Since I like to use the PIC microcontroller in my projects I figured it would be nice to make a mini development board that could fit onto a breadboard and already had a power circuit and programming circuit connected. This way I won’t have to rebuild the same power + programming circuit everytime I start a new project. This article describes my design process so that you can build one too!”

“During World War I and slightly before World War II, military fighter aircraft had machine guns mounted to fuselage of the plane. These machine guns were mounted right behind the propeller. The first question that comes to mind is how can the gun fire and not hit the propeller blades as they are spinning? Some planes had special steel plates mounted to the propeller to keep the bullets from shredding the propeller.”

“The original design for the PIC10T used the ENC28J60 standalone ethernet controller and a PIC18F4620, this article is an updated version of the original project page, which will cover in more detail the basic hardware design, some recommendations and troubleshooting tips for putting together your prototype.”

“The objective for this project was to build a portable unit containing a HD44780 Character LCD that could be updated through a wireless link. For the wireless communication link, I chose to use a low-power, short-range, ZigBee device. The 1 mW Digi XBee modules fit the bill nicely, and they’re reasonably priced.”

“Normally, Papydoo is asleep. The enclosure sits on top of a vibration sensor. Papydoo is waken up by a sufficiently strong vibration. Two eyes are then displayed on the LED matrix, wandering randomly around. After a few seconds with no vibration detected, the eyes close and Papydoo goes back to sleep.”

“The AVRcam is a small, real-time image processing engine capable of tracking colorful objects. The system was specifically designed to provide hobbyists with a vision system that can be easily added to their projects (robot, security, monitoring, etc).”

“In this article we will use a pair of XBee modules to build a quick wireless interface which will be used to wirelessly control a servo based pan and tilt system which can move my camera 45 degrees in any direction, left-right-forward-backwards. ”

“The Uzebox design guidelines were simple: keep complexity and parts count low, yet don’t cut on quality. And the ATMega644 greatly helped me to accomplish this. They have so much integrated peripherals and functions (like SPI, UARTS, counters, analog comparator, pull-ups, etc); it was ‘almost’ too easy to attain that goal. Let’s a have look at the big picture and then I’ll describe the global flow and what each block does.”
