Work-in-progress: an Atmel AVR ATmega8 connected up to an RS-232 level shifter and some robot sensors. I'm actually using the hall-effect sensors in the CD motor to substitute for opto-reflective sensors on the robot's drive gear. One side of the robot is opened up, showing the gears, although three of them are removed at the moment. The RS-232 level shifter, a MAX232 chip, is connected to an HP 95LX handheld computer, acting as a terminal at 9600 baud.

Have you ever thought that most of our perception about the robot is based on the Hollywood movie! The well-known 3CPO and R2D2 from Star Wars until the little cute garbage compacting robot named WALL-E; all of these machines are example of our dreams or should I say our quest to what we all think about the robot should be. Although the robot that we are going to build here is still far away from the technologies shown on those movies but at least it will give you an introductory to the robotics world. for more information please visit www.ermicro.com/blog/?p=983

We developed a music player based on the Arduino Lilypad microcontroller board. The system plays a kids song with the using the acccelrometer. Five different directions represent the the notes C, D, E, F, G which are used to play little songs. We programmed the LEDs such that they indicate the flow of the melody. The sample video plays the beginning of "Hänschen Klein" [Wikpedia says: "Hänschen klein" is a traditional German folk song and children's song originating in the Biedermeier period of the 19th century. The title translates to English as "Little Hans". en.wikipedia.org/wiki/Hänschen_klein] Find the video of the system in action unter: www.youtube.com/watch?v=x2INT71RGfI

A Switec X27-168 stepper motor wired up to the Arduino. The pointer was moving when I took the photo, hence the blur. These little geared stepper motors are designed to be used in car instrument panels, as the speedo, rev-counter, fuel gauge and so on. Not a great deal of torque, but quick to respond and high resolution (due to the internal gearing).
There's a software library to drive this type of motor, called Gaugette: github.com/clearwater/gaugette
Lissajous figures are interesting curves that occur in systems where oscillation happens in more than one direction, for example when a pendulum hanging from a string moves in the plane.
These pictures are from an easy persistence of vision approach to playing with Lissajous figures. Read more about this project here.

Talks and performances by people doing strange things with electricity
Fri 23 March 2012, 6.30-10pm with interval at the Showroom Cinema, Sheffield.
Dorkbot is a meeting of people interested in electric/electronic art in the broadest sense; robotics, kinetic art, microcontrollers, interactive art, algorithmic music, net.art... The only real conditions are that it is a bit strange and involves electricity in some way. It is really defined by whoever turns up, be it engineers who want to be artists, artists who want to be engineers, or the otherwise confused.
This MEGADORK event features a cabaret of talks and performances from among the UK's dorkiest, to entertain and amaze:
Paul Granjon - A strange performance from the world renowned self-styled robot artist.
Patrick Tresset - Talks about his drawing robot Paul (on show as part of the Alan Turing: Intuition and Ingenuity exhibition).
Daniel Jones and James Bulley - talking about generating live music from patterns of weather.
www.variable4.org.uk/about/intro
Sarah and Jenny Angliss - playing robot music from past futures.
spacedog.biz
Sergi Jorda - talks about the Reactable tangible tabletop music playground (which you'll be able to try out at the Central Library Saturday 24 March)
Dan Stowell - Demonstrates his use of the Risset illusion in techno music.
Silicone Bake - Live coded pop songs about love, death and counterfeit watches, where all lyrics are taken from spam emails.
Megadork is curated by Alex McLean.
Dorkbot started in New York, spread to London, and now dozens of cities around the world, including several active UK chapters; Sheffield, Bristol, Anglia, Newcastle, Cardiff and Alba (Scotland). Find out more at: www.dorkbot.org

Also available in a 44-pin package, the PIC18F47J13 MCU features XLP technology for eXtreme Low Power consumption and mTouch™ capability for implementing capacitive touch sensing user interfaces.
Here's the result of carelessness when ordering microcontrollers (aka μCs, "μ" for "micro" and "C" for "controller). They, like other chips, are available in different sizes. Same silicon inside, but varying carriers. As you'd expect both the silicon and the packages have gotten smaller over the years, but the old larger packages are still available for many chips for compatibility with existing circuitry, and, well, I'm not sure why else.
So the other day I decided the prototyping of my Nixie tube watch was getting toward where I could start thinking about making some circuit boards, so I chose a suitably small form of the watch's microcontroller and ordered a few - I thought.
The chip at the top is in the classic Dual Inline Package (DIP). There's one like it wired up in my nixie watch prototype. Though fine for prototyping, this form of the chip is much too big to be used in an actual watch - even a big fat nixie watch.
The chip in the lower right is the size I meant to order - the Small Outline Integrated Circuit (SOIC). They're reasonably small, and I've soldered them into circuits successfully before.
I goofed up, though, and the little guy below Lincoln's nose is what I ended up with: the Micro Lead Frame Package (MLF). This one is lying on its back. It's a great size for use in a watch, but much teenier than anything I've attempted to solder before. That is, I've soldered stuff that is overall no bigger than that, but this chip needs 20 separate solder joints, 5 on each edge where the little light bits are. Those are half a millimeter apart - yikes!
But you know what? I think I'll give it a try, just to see if I can pull it off. With a bit of care and solder flux, a lot of magnification, and a super-duper fine point iron tip, I bet I can get it to work.
The Rainbow Lighter V2.2 completed, it took several evenings to get it all put together. I grabbed an Altoids tin from my bits'n'pieces supply bag for the 9-volt battery holder.
There is a piece of 1mm black foam (neoprene) attached to the back of the circuit board. The Altoids tin attaches to the foam with a piece of velcro to hold it in place.
Thanks to El Endemoniau for inspiring me to create my own Cr@p Lighter.
My version is using tri-color (manually controlled) LEDs so each individual LED is three LEDs combined. Each one can be lit up to be red, green, or blue...the cool part being that you can then generate different colors using combinations of these three colors. For example, red & green = yellow, green & blue = cyan.
The next step is to develop software for the AVR microcontroller so I can display patterns and text. ;-)
The servo motor is used widely in model hobbyist such as airplane R/C model for moving the rudder, ailerons, elevators and acceleration control or in the car R/C model for steering and acceleration control. In this tutorial we will learn how to control the servo motor as well as the simple close loop control algorithm for this servo motor. For Further information please visit www.ermicro.com/blog/?p=771
