These days we are living and surrounding by many tiny computers called embedded products. Unlike the general purpose desktop computer that we use for browsing or typing our email, this tiny computer is designed to do only a limited specific task.

And this CNC board is significantly less painful to assemble than the previous one.
I got around to trying the circuit board I built yesterday and it works! Shown here is a PIC 12F675 microcontroller (mcu) running the mcu equivalent of Hello World, making an LED blink.
A microcontroller is a very small computer, here shown in the black package which is a little bit bigger than a quarter-inch on a side. They vary widely in physical size and capabilities and are typically used as the brains of control circuitry such as fuel injection systems, smart battery chargers, stuff like that, on up to fairly powerful devices like MP3 players. There's a hobbyist community centered around them and people come up with some pretty interesting stuff.
The idea behind a Hello World program is that it's the minimum necessary to show that you are able to develop a working program in whatever environment it is you're using. For most computer languages, you're able to assume some kind of device that can output text, whether an old-style terminal console or a web browser or whatever (and the traditional text, attributed to Brian Kernighan in the early 70s, is "hello, world.") With a microcontroller, though, the simplest setup doesn't have any text output. Instead, a light-emitting diode (LED) is connected to one of the chip's pins and a program written to make it blink. Blinking is the simplest way to show that the program is running - steady-on might happen by accident depending on how the circuit is wired. The blink shows both that the program is executing properly and that it's running at the speed you expect.
The way MCU development works is that you write the program for the little chip on a PC and send it (nowadays) through a USB cable to a device called a programmer. The programmer configures the MCU's memory to contain your program and off you go; newer programmers like the PICkit 3 pictured here are also able to let you run the program one instruction at a time and observe its behavior on the development PC. The circuit shown here doesn't support that, but I don't use that functionality much anyway - my projects tend to be more complex than Hello World but not hairy enough to need that kind of debugging power.
I built this little setup so that I could make MCU-based projects for my new year 2012 resolution of making some object every week. One problem I've had with my electronics hobby to date is that I never finish anything; it's enough for me to show that I can get something working, then I don't take the last step of putting it in some sort of durable form that can then be presented to someone and used. Mostly, that's not really a problem, since there isn't any obligation for a hobby to produce useful things. But I would like to actually put some stuff in peoples' hands.

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.

Robot Charlie's radio transmitter, it has an AVR ATMEGA168 microcontroller inside to take the data from the Wii Nunchuck, decode it, and transmit the decoded data with a radio transmitter.
My friend wanted something he could install in his truck that would make it so his taillights would flash a couple times when he stepped on the brake, so they'd be more attention grabbing. Since that sounded like something I could make, I made one for his Christmas present.
This was taken using his present to me, a new lightbox. It seems there's perhaps a little more to using one of these than I previously thought.

The processor is an ATmega168V AVR microcontroller.
Made from a fluorescent clock kit (adafruit.com). It's a really well thought out design that's both easy to assemble and fun to make. In the end, you've got a cool and functional clock.

I didn't have a USB2TTL cable laying around and so I looked in to what one entails. Turns out the magic in those cables I already had in a break-out board.. I just soldered on a header and used a little breadboard to pull over the pins I needed. But alas, it didn't matter. All the magic was gone from that FTDI chip anyway. Though I've ordered another one of those rather than paying more for a whole cable that doesn't give me the same flexibility.
This shows the new controller and lights being tested in Nestbox1 for the 2009 season. The heart of the system is an AVR microcontroller (the ATtiny2313). It controls eight white LEDs and two IR LEDs, and communicates with the controlling computer via an EIA-422 link. Both the EIA-422 signals and power are carried over a single CAT5 cable.
The computer sends signals to the controller to vary the light levels throughout the day, at night only the IR LEDs will be on so as not to disturb any occupants.

David presents an interfacing Arduino and Adobe Flash. Dorkbot crowd makes up a quick game called "Busy Proctologist" using some craft items, a pressure sensor, and the goatse image.
The crowd concluded after finding a latex glove, a styrofoam ring, some bubblewrap, and some red and brown felt, and a pressure sensor that the game would be called "Busy Proctologist."
Gameplay involves "examining" as many patients in the day as possible (measure by a 1 minute timer in Flash) without causing undue discomfort during the rectal exam (exceeding a moderate pressure range measured by the sensor and arduino.)
