The MC13224 from Freescale is a ZigBee System-On-Package device. The three dies pictured are the microcontroller, radio, and flash memory.
The kiibohd PCB makes use of the open sourece MC HCK microcontroller (mchck.org). This is the first keyboard I’m aware of that has used it.
An Atmel ATtiny24 microcontroller drives an R/C servo wich in turn rotates a line LASER taken from a LASER level.
The microcontroller runs a software real time clock and turns the servo and the line LASER to mimic the shadow cast from the style of a sundial as the time goes.
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.
These pictures are from an easy persistence of vision approach to playing with Lissajous figures. Read more about this project here.

Picaxe microcontroller project: thermostat. The serial 7 segment display (from Sparkfun) shows actual temp in Fahrenheit. Setpoint adjusted with the potentiometer on the right. (display alternated between showing setpoint and actual temp) The microcontroller is the Picaxe 18X in SOIC form on the bottom, temp sensor is the Dallas 18B20, mounted on the wires to the right. Heater is controlled by an Omron 653-G3MB-202P4DC5 solid-state relay (black box left of 7 segment display).

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 chipKIT™ Pro MX4 is a microcontroller development board based on the Microchip® PIC32MX460F512L, a member of the 32-bit PIC32 microcontroller family. It is compatible with Digilent's line of Pmods, and is suitable for use with the Microchip MPLAB® IDE tools. The chipKIT Pro MX4 is also compatible for use with the chipKIT MPIDE development environment.
The chipKIT Pro MX4 provides 74 I/O pins that support a number of peripheral functions, such as USB controller, UART, SPI, and I2C ports as well as five pulse-width modulated outputs and five external interrupt inputs. Fifteen of the I/O pins can be used as analog inputs in addition to their use as digital inputs and outputs.

This is the MSP430F5438 microcontroller from Texas Instruments. The 40 megapixel die photo had to be significantly reduced in order to fit Flickr's limit, so email me if you'd like it in full resolution.
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.)
Microchip Technology Inc., a leading provider of microcontroller, analog and Flash-IP solutions, today announced the expansion of its RF power amplifier portfolio, with the addition of the new SST12LP17E and SST12LP18E devices. The SST12LP17E is the smallest fully matched power amp in its class, requiring only one DC bypass capacitor to achieve optimum performance. The SST12LP18E is a lower-cost, lower-voltage alternative to Microchip’s popular SST12LP14E power amp. It offers the lowest operating voltage of any Microchip RF power amp, while operating at -20 to +85 degrees Celsius. The devices feature operating voltages as low as 2.7V, linear output power as high as 18.5 dBm at 2.5 percent EVM using IEEE 802.11g OFDM 54 Mbps, and 23.5 dBm for IEEE 802.11b and a high power-added efficiency of up to 38 percent for IEEE 802.11b. They are ideal for embedded WLAN applications where small size, high efficiency and low-battery voltage operation are required, such as in the consumer electronics market, in cell phones, game consoles, printers and tablets.
This is a high-res scan of the PCB, for those that care. The little extra PCB up top is the PIC microcontroller added by RetroZone to convert this into a USB paddle.
I considered building the Minifilter into this loudspeaker enclosure, but in the end I decided against it, preferring the flexibility of not being tied down to something quite so bulky when using the minifilter.
However it would have been perfectly feasible to do so.
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.

Working on a simple quad, it's been a project I've wanted to do for quite some time, and some random thoughts I had led me to try it now.
This is the main PCB, its roles are to distribute power, watch sensors (gyro, accelerometer, magnetometer) for stability, and provide control signals to the 4 rotors. Also has two central connectors for add-on boards; I am working on a board with an nRF radio and a flash chip for flight logging, the other could be used for other experimental features.

This Sparkfun treat arrived late last week and I have been utterly consumed by my class until now. So I broke out the new Android IOIO board from Sparkfun, a convenient package all wrapped up and ready for easy access from the Dalvik platform. I have the board cabled to my Nook Color.
In this photo, the app on the left, "Hello IOIO" simply toggles the yellow LED next to the microcontroller. The RED LED signals power. This board requires external power and can power the attached Android device if there is enough current to power everything in the circuit.
It's a convenient platform. One can imagine using it as a versatile physical computing interface for common and inexpensive devices like the Nook or cast-off Android phones.
I study electronics on third year, and I will probably be on the third year also next year, so it’s best time to finally get some interest into my studies. I find microcontrollers are very powerful tool to know, so I’m playing a little bit with Microchip PIC’s with PICKit2. I’m curious to see what these little chips can do :)
Sanguino is an open source Arduino-compatible microcontroller board that is based on the Arduino, and inspired by the Boarduino form-factor. It uses the atmega644P chip which has 4x the memory, ram and 12 more GPIO pins than the Arduino's atmega168.
