This fabric-based microcontroller project has been taking up more and more of my life. Every corner turned, every goal reached, opens up a thousand new possibilities and a thousand new tests to make.
Here I am with Tara O'Con, presenting at Maker Faire NYC. Thanks to Chris Cummings for the photo!
The chipKIT PGM is designed to work with the MPLAB® and MPLAB X development environments available from Microchip. This allows the chipKIT boards, for example, to be used as a more traditional microcontroller development platform using the professional tools available from Microchip. While the PICkit™3 programmer can generate programming voltages needed to program all Microchip PIC devices, the chipKIT PGM can only program devices that are programmable with 3.3V programming voltage. Further, the PICkit3 can source a small amount of current to provide power to some boards being programmed. The chipKIT PGM does not provide power to the board being programmed.

I think I can call myself an accomplished solder-er, after adding those header pins without a problem.
This is a view of the electronics inside the model R/C tank I am designing on a gearbox + Tracks & wheels from Tamiya. The radio is Hitec and two receiver servo outputs feed my microcontroller-based Pulse Position Modulation output into Pulse Width Modulated power output to the two motors.

They feature excellent latch-up immunity, enabling extremely robust applications in the consumer and computing markets, such as digital power conversion, DC-to-DC power supplies, three-phase BLDC motor control and telecom equipment.
Gotta show off a little! I've had an itch to get back into microcontrollers for a while and finally bit the bullet and went for it! At my young age, I gotta keep the ol' brain active!
The Arduino micros are cheap and a very inexpensive way to create all kinds of fun projects! Programmable with C/C++ language, I've actually been able to remember quite a bit. It's been years!
"Hello World!" is the classic first code most folks write for almost every programming language.
Btw... the microprocessor is that tiny thing on the left with the red power LED. It's an Arduino Nano.
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.)
I made a Mandelbrot Set viewer with an Arduino. It does zooming and it's pretty cool.

One of the commonly asked questions when we move to the bigger and powerful 16-bit microcontroller is do we really need it? As the 8-bit microcontroller is already suite almost all of our needs from a simple blinking LED to more sophisticated embedded application such as robotics
The 8 pins PIC12F683 microcontroller is one of the smallest members of the Microchip 8-bit microcontroller families but equipped with powerful peripherals such as ADC and PWM capabilities. This make this tiny microcontroller is suitable for controlling the DC motor speed. In order to demonstrate the PIC12F683 capabilities and to make this tutorial more attractive, I decided to use the PIC12F683 microcontroller to generate simple and yet fascinating laser light show from a cheap keychain laser pointer.

When found by the artist, this small oyster shell had a perfectly round hole drilled into it, perhaps by a predator. The hole was a perfect fit for a light-emitting diode.
It dimly blinks the “Arecibo message,” a transmission sent towards star cluster Messier 13 from the then-new Arecibo radio telescope in 1974. Though it was considered a “message to aliens,” the Arecibo transmission was brief, less than three minutes in duration, and was sent only once. It was a demonstration of the telescope creators’ technical prowess more than an earnest attempt to advertise humanity.

My company, AVIX-RT, develops and markets an RTOS for Microchip PIC24/dsPIC microcontrollers. Since the main focus is on software, for hardware I am always looking for easy solutions where I do not have to spend a lot of time reaching my goals. I found such a solution with Schmartboard. Schmartboard enables me not only to create a converter, making it easier to work with SMD devices. Schmartboards offer much more than this. These boards allow me to put complete circuits on a single board reducing footprint and ‘Time to Prototype’, this all with minimal effort. I really love these boards since they allow me to focus on my main goals. More information can be found at www.avix-rt.com

This Arduino shield by Bulgarian company Olimex is a rather strange beast which incorporates an onboard PIC microcontroller to read serial data in and display it on the 16x2 LCD using a custom library (amongst other things).
I'd mistakenly read the manufacturer's name as Olimerx, not Olimex,
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

Simple prototyping boards for AVR microcontrollers. This one is designed for the Atmel ATtiny2313, and you can read more about it here. It's a complement to our earlier ATmegaxx8 board.
The wires at the top of the photo connect to a 9-pin D-connector. I can then plug a stepper motor (or some other kind of half-amp load) into that.

Microchip announced a new addition to its PIC12/16LF155X 8-bit microcontroller (MCU) family with the PIC16LF1554 and PIC16LF1559 (PIC16LF1554/9) devices. The PIC16LF1554/9 includes two independent 10-bit 100K samples per second Analog-to-Digital Converters (ADC) with hardware Capacitive Voltage Divider (CVD) support for capacitive-touch sensing. This unique ADC configuration enables more efficient sensor acquisition and assists with advanced touch-sensing techniques for extremely noisy environments, low-power applications, matrix keypads and water-resistant designs.

This is a backup board (the proto-board versions come in sets of three anyway) showing the components. The large IC is the PIC16F887, an 8 bit microcontroller with 38 IOs (including 10 A2Ds if desired - all output pins are programmable on the fly). The small IC to the left is the Dallas Semi conductor Real Time Clock chip, which is interfaced to the PIC with a I2C serial bus. The large disk to the left is the battery used to keep the RTC alive when the unit is not powered. The white header next to the battery is for the hand controller and autoguider (ST4) interface. Above the PIC is the In-Circuit Serial programming interface. To the right of the PIC are the two daughter boards that drive the steppers in any of the various modes (from full to 32 microsteps) Under the daughter boards there are jumpers which can be used to configure the main board to use either these (based on a TI chip) or similar boards (full to 16 microsteps) based on the Alegreo driver chips. The crystal for the processor is 20mhz, giving an instruction cycle time of 2e-7 seconds. When both axes are running at the full planned rate (960X sidereal) less than 50% of the CPU time will be used. The board will also support one of the PIC18F chips with a 40mhz clock with more performance and memory. All through-hole technology for ease of repair and assembly.
Game controller with 2 microcontrollers inside (ATTINY85), both generating algorithmic music.
For each microcontroller, the 2-axis analog stick controls two variables of the currently selected algorithm, the switch of the analog stick cycles the algorithms and an additional switch is used to mute/unmute the sound.
Note: Nothing fancy here, this a just a demo with only 4 algorithms and the same program on both microcontrollers.
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.

This was a later test to see if I could mill a tube, kinda like a little bullet casing. The answer is a resounding "kinda." It still suffers from the grain problem mentioned in the previous pic, wherein bars formed with crappy aluminum don't mill evenly as spun around beneath the end mill. Certain edges mill cleanly, while others seem to flake away, leaving lost, unsharp edges.
In the background you can see the DIN cable plug into a simple board I made that connects to a BASIC Stamp BS2p40, which is on the stamp dev board (with the green power LED). All it does it kick out a steady stream of rotation commands to slowly rotate the rotary table. In this pic, the table sits on the angle plate, which is just there to raise it up enough to give the rotary table's CNC motor (foreground right) clearance over the Y axis handwheel (out of frame bottom). On the rotary table is a 4-jaw independent chuck, which is holding the 0.25"x0.75" stock vertically for the milling. Using the rotary table, I cleared away the space around a little bar shaped piece, and then began milling the tube into the center of it. Obviously, I can't get much depth with that tiny 1/8" end mill, and moreover, this operation is far more suited to both a lathe (almost next on my wishlist), and better grades of aluminum, or other metals entirely.
Again, just another test. Note also the white copy paper and black electrical tape way-guards. I don't like getting shavings around the exposed Y-axis threaded rod, and I haven't made a fancier system yet. This works quite well for now.
