Dorkbot Bristol, December 2008: Drew operating the dropper on his high-speed photography rig. It's based on an Arduino and triggers the camera shutter and flash at precisely the right moment to capture the splash.
It's an alphanumeric persistence of vision display. This photo was taken by setting the camera on self-timer with a 2.5 s exposure. When the picture started going, I just walked through the frame at normal speed. Ha! I'm invisible.

An Atmel ATtiny24 microcontroller drives an R/C servo wich in turn rotates a line LASER taken from a LASER level.
The microcontroller runs a software real time clock and turns the servo and the line LASER to mimic the shadow cast from the style of a sundial as the time goes.
Microchip and Digilent's chipKIT(tm) Development Platform is the first 32-bit-microcontroller-based, open-source development platform that is compatible with Arduino™ hardware and software. More information is available at: www.digilentinc.com/chipkit.
The four-member PIC24FJ256GB210 microcontroller family integrates USB for Embedded Host/Peripheral/On-the-Go and 96 Kbytes of RAM. This large RAM enables the buffering of sizeable amounts of data and better overall throughput, for applications such as Ethernet connectivity, remote sensing, data logging and audio streaming. It can also be used to store generated images or data for dynamic content, such as real-time, remote sensor data graphs. In combination with Microchip’s free USB software library and TCP/IP stack, these MCUs lower system costs and footprints in a broad range of industrial, instrumentation/measurement, medical and consumer applications.

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

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
A Switec X27-168 stepper motor wired up to the Arduino. The pointer was moving when I took the photo, hence the blur. The motor's windings only consume about 20mA, so it's safe to drive directly from the pins of an AVR microcontroller -- although it does need protection diodes.
There's a software library to drive this type of motor, called Gaugette: github.com/clearwater/gaugette
Microchip Technology's RE46C165/6/7/8 photo smoke-detector ICs make it easy to quickly determine which detector in an interconnected loop triggered an alarm. The ICs’ low energy use enables smoke detectors with a battery life of 10 years, and an interconnect filter enables a connection to other devices, such as CO detectors.
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.
I originally used this keyboard many years ago with a UNIX computer. Recently I dug it out and added a PICAXE microcontroller to use it to change the messages on the Green LED Clock.

The MCUs feature an on-chip 12-bit Analog-to-Digital Converter (ADC) and a peripheral that enables mTouch™ capacitive touch-sensing user interfaces. They are ideal for applications in the automotive (e.g. body control modules, automotive lighting, door/seat/steering/window control, HVAC control), industrial (e.g. security systems, elevators and escalators) and medical (e.g. glucose meters, patient-monitoring devices) markets.
