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.
Microchip announced an expansion of its 8-bit PIC® microcontroller (MCU) portfolio, with the peripheral-rich, low pin count PIC16(L)F161X family. These new MCUs expand the offering of Microchip’s Core Independent Peripherals (CIP), which offload timing-critical and core-intensive tasks from the CPU, allowing it to focus on other application tasks. Additionally, this family integrates fault-detecting hardware features to assist engineers in developing safety-critical applications. For more info, visit: www.microchip.com/get/VLDM
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

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

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.
Microchip Technology's RE46C190 3V photo smoke-detector IC with horn driver and boost regulator. The world’s first smoke-detector IC to offer low-voltage operation with programmable calibration and operating modes, the RE46C190 IC enables the desired operating modes to be selected and calibrated during manufacturing. This simplifies smoke-detector design and manufacturing, and reduces component count, and cost. Additionally, the IC’s low operating current of 8 microamperes typical enables up to 10 years of operation from a single Lithium battery. Two Alkaline batteries may also be used to power the RE46C190.

Customers can reuse or customize the free firmware for their needs, which further shortens time to market and enables them to differentiate their products in the marketplace.
The camera body is a small plastic box from Maplin's. The ribbon cable connects the sensor chip to the Arduino, and supplies 5V power.
This box contains a microcontroller that keeps the box locked from the inside until its GPS sensor detects that the box is located at coordinates I can specify beforehand. Basically, I program the box for a certain location and lock a treat inside. I give the box to someone and they get to figure out what the box does and how to multilaterate the position the box "wants" to reach.
I originally made this over 30 years ago. With the technology available then it needed another big metal box. Recently I took it down from the back shelf and managed to get it all in the nice old box by using a PICAXE micro-controller.
One of the advantages using the Microchip PIC microcontroller Pulse Width Modulation or PWM for short is; this PWM peripheral circuit is designed to control the DC motor using the full bridge mode PWM feature. The PWM peripheral works by supplying the correct signal to the H-Bridge DC motor circuit such as speed controlling and changing the DC motor direction.

The PIC16F75X family of 8-bit microcontrollers (MCUs) featuring intelligent analog and core-independent peripherals, making them ideal for general-purpose applications, as well as power supplies, battery charging, LED lighting, power management and power control/smart energy applications. The new PIC16F753 MCU builds on the success of the popular PIC12F752. The PIC16F753 offers all the key features of the PIC12F752, such as the integrated Complementary Output Generator (COG) peripheral that provides non-overlapping, complementary waveforms for inputs such as comparators and Pulse Width Modulation (PWM) peripherals, while enabling dead-band control, auto shutdown, auto reset, phase control and blanking control. Additionally, the PIC16F753 offers an Op Amp with 3 MHz of Gain Bandwidth Product (GBWP), and a slope compensation circuit to help in Switch Mode Power Supply applications.

This is the CPU board with a 8-bit microcontroller PIC12F629, a 20MHz crystal and a bypass capacitor to reduce the noise. This little board goes into a 70-210mm f/2.8 lens and an identical one is made for a 28mm f/1.8 lens. There is an internal oscillator but can only run at 4 MHz which is too slow for this application.
