The Digilent Pmod MTDS is a gorgeous 2.8" touchscreen display with a powerful on-board microcontroller that performs graphics processing tasks. The display is a capacitive touchscreen with QVGA resolution (320×240) and 2 finger multi-touch support.
The most compelling aspect of the Pmod MTDS is the programming experience provided by its Multi-Touch Display System (MTDS) Firmware and the associated libraries. These allow you to design sleek, stylish user interfaces very quickly and with very little code. The timing dependent tasks are handled by the firmware, so integrating the display into existing projects is also a snap. Some of the key functionality provided by the libraries include the ability to draw basic shapes and text, draw images stored on microSD with binary transparency, draw buttons and easily check if they have been pressed, and check the status and location of the user's two fingers. The libraries are supported in Arduino IDE and Xilinx SDK, and have been tested with Ardiuno, chipKIT, and Arty host boards.

Some recycled parts to make a row of LEDs to plug into the AVR's I/O port. A ten-LED array, some protoyping board, a 16-pin right-angle header and eight 330Ω resistors. I got the LED array out of a scrap telephone control panel, and the resistors were from FreeCycle.

The PIC16(LF)190X family supports many general-purpose applications and enables the implementation of LCD into any design, such as security tokens, smart cards, medical devices, home appliances, or any application involving a simple LCD display.
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.

Motor Base
This is the basic Beakman's Motor base from my original page. The motor is sitting on a base made from Brio pieces.

Instructables
The six-member PIC18F46J11 and the six-member PIC18F46J50 8-bit MCU families feature typical sleep currents of less than 20 nA. The general-purpose PIC18F46J11 MCUs provide up to 64 KB of Flash program memory and the peripheral set of a typical 64- or 80-pin device in only 28- or 44-pins; while the PIC18F46J50 devices add integrated Full-Speed USB 2.0 to enable connectivity for embedded applications requiring remote field upgrades or the downloading of data.

Some extra parts for the Atmel AVR boards. I plan to build another one with an ATmega32 chip, so I'll need the 40-pin DIL socket for that. There's a good selection of 0.1μF capacitors for decoupling and a spare 10-pin programming connector.
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.

New flash trigger I made today, with the intent that I'm going to write some external interrupt code for one of my ATmega16 microcontrollers tonight. This one detects the interruption of a laser pointer light beam, and signals pretty much right away.
The signal will interrupt the microcontroller, which will set the timer interrupt (for roughly 1 millisecond), and count off n milliseconds before firing the flash. Assuming I can get the coding done, later tonight I'll post a series of water droplet shots at various closely spaced intervals.
The timing won't be exact, since I'm using the microcontroller's internal oscillator at 8 MHz, but it should be consistent enough to test the concepts involved. When I think I've got it where I want it, I'll order a crystal, which will be much more accurate than the internal oscillator. I might even get a 16 MHz crystal, to cut the extra code execution microseconds in half. A more enthusiastic person than me might count instruction cycles and remove them from the timer count, but give me a break, this is for fun, after all...
How big a difference is there between .001000 seconds and .001014 seconds? Not enough for me to count instruction cycles...
I made a prototype to test how the LEDs would work around the rotary encoder. They worked, but the board was too clunky to get a good feel for how the knobs would work.
