Building on the previous successes with the chipKIT WF32, the Wi-FIRE uses the same 43 available I/O pins, 12 analog inputs, 3.3 operating voltage, 4 user LEDs, potentiometer, buttons, uses MRF24 on-board wireless module, microSD Card, dedicated SPI Signals and high efficiency switching 3.3V switching power supply for low-power operation.
The Wi-FIRE is significantly faster than its WF32 counterpart, with 200 MHz operation speed, 2MB of Flash, 512kB RAM, High-Speed USB and a 50MHz SPI. The PIC32MZ core includes the MIPS M5150 CPU Core from Imagination Technologies. The M5150 is a highly efficient, compact core that is optimized for cloud-connected based projects, using Imagination Technologies' FlowCloud software.

This photo is from a workshop on Program Night at the Suncoast Camera Club in Pinellas County, Florida. It requires the use of either a Micro Processor or at least a Micro Controller. You have to be able to control the time between the release of the Droplet (of Water) and the triggering of the camera. It is also suggested to use a dye to color the water.
Even with an adjustable timer, the capture is a Hit or Miss proposition. These two photos were taken with a specialized camera setup belonging to Presenter Ron Mayberry. Each camera club member brought a Compact Flash Memory Card, which Ron inserted into his camera to take the photo after which the Flash Cards were returned to each member with the recorded photos.
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

The Arduino Uno is a microcontroller board based on the ATmega328
It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.

Solder side of my TiVo IR controller I made becasue the IR blaster doesn't work on that TiVo, which has Product Lifetime, and is beyond warranty, and modifed to no end, so they can't take it back.
The board takes the serial commands meant for a DirecTV receiver, and basically decodes them and interprets them into what buttons to push on the OEM remote for my satellite receiver, which it does with a 4051 and 4052 CMOS switch (one doing row, the other column). I would have used two 4051, if I had two, but for that job, a 4052 is adequate. In there behind the wire (which is the power wire that gets power from the TiVo's USB port) is the Max213 serial receiver driver chip.
Just about all of it is done surface mount, by hand.

Pixel VGA, version 1 (Floor Cluster) - Garnet Hertz
Two dozen old computer monitors occupy the center of a gallery floor in a cluster facing the wall. Each screen is controlled with custom electronics to create pulsating and strobing patterns, casting a colored wash across the darkened gallery.
Dimensions: Variable (approx 3m x 3m). VGA monitors, custom electronics. 2011.

My traffic-light PCB plugged into an Arduino Nano via the red female headers. Only changes needed to the sketch were the pin assignments.
The uC32 features a USB serial port interface for connection to the IDE and can be powered via USB or an external power supply. The board takes advantage of the powerful PIC32MX340F512 microcontroller, which features a 32-bit MIPS processor core running at 80 MHz, 512K of Flash program memory, and 32K of SRAM data memory.
The uC32 can be programmed using MPIDE, which supports PIC32. It contains everything needed to start developing embedded applications. In addition, the uC32 is fully compatible with the advanced Microchip MPLAB® IDE and the PICkit3 in-system programmer/debugger.

Found plastic flowers, foam, light sensors, mp3 players, microcontroller, speakers, birdsong
An ersatz version of nature; beautiful, yet a little bit deadly when one considers the natural resources required to create such impeccable imitations of vegetation. Is it also a reflection of human hubris... what else motivates the manufacturing of fake flowers? Why replace the ephemeral with plastic permanence? What joy is there in a whiff of a petroleum-based bouquet rather than the delicate scent of a rose? Secret Garden offers an opportunity to contemplate these questions at the same time it tries to seduce you with extravagant color and joyous birdsong performed just for you.
