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.
At the top there is the spindle drive (20hp) and 3 servo drives.
On the right (with all of the blue wires) is the new PC interface, we're using a Mesa 7i77 board.
CNC electronics enclosure with a switched-mode power supply, a solid state relay for spindle control, three A3977 based stepper motor drivers for x, y, and z, a controller power supply, and the controller board. The controller is based on Microchip PIC18F8680, and the milling program is read off a USB stick using a VNC1L (the board is not shown). The whole system is controlled using a graphical touch screen LCD.
Using an ATtiny 85 to control power supply. Push button toggles power on/off with ATtiny in charge of reading button after power on and actually powering down circuit.
Long shot of the area to the right of the stage. Lots of traffic to and from the Women's restroom at this point.

This is the input point of the household 220 V ac and the output of all secondary voltages.
This is the heart of the layout.
All selves can be extracted so as to have access to components.
It goes without saying that this is also hand made as well...

A new generation of cheap lightweight plastic electronic technology that does not require silicon, but which is optically transparent and can be coated onto everyday objects would transform our world.
"Working collaboratively with industry is not only satisfying in that I see aspects of my work translate into real engineered products, but it provides inspiration for new avenues of research too. Roadmapping then allows me to critically assess how I should be developing my research portfolio and engaging with industry to maximise the likelihood of productive collaboration."
—Dr Andrew Flewitt
Imagine electronically updated food labels, computers embedded in our armchairs, even contact lenses linking us directly to the Internet to bring us into the age of plastic electronics. In this video podcast Dr Andrew Flewitt and Dr Robert Phaal both from the Department of Engineering and Scott White serial entrepreneur and CEO of Pragmatic Printing talk about the creative partnership forged between different parts of the Department of Engineering and outside companies that enable the technology and research in this area to be exploited successfully.
