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.

The Ethernet PICtail™ Daughter Board provides a cost-effective method of evaluating and developing Ethernet control applications. The board is designed for flexibility and can be plugged into a wide selection of Microchip’s standard PICDEM™ demonstration boards. The development board is populated with the 28-pin ENC28J60 Ethernet controller which interfaces to the RJ-45 female connector. With a standard 28-pin PICtail pin out, the board is easily interfaced to Microchip’s 8-bit demonstration boards.
Features
10BASE-T Ethernet
RJ-45 Female Ethernet Connector
Plug in compatible with these evaluation and demonstration boards:
PICDEM HPC Explorer (DM183022)
PICDEM LCD Demonstration Board (DM163028)
PICDEM Z Zigbee Demonstration Board (DM163025)
Together with the experience of the promoter in projects involving Government Sectors and Private Industrial Sectors,Techon Electro Controls now looks forward to participating in the International projects to carrying out Design, Manufacturing,Installation and commissioning of Small,Medium & Large Captive Power Plants as well as complete power utilization & distribution solutions.

Wires!
I was experimenting with controlling an ADC to drive some laser positioners. This worked :)
I've also rebuilt this into a little more comprehensive circuit board for future use. (Also added an output stage to give me a wider voltage swing, and some stuff to turn on/off a laser diode)
This is built on a pcb I designed to breakout the LPC134x microcontroller, explicitly to enable this sort of prototyping :)
A fun and easy way to get started with programming and hardware interaction. The Inventor Kits are used for classes and special programs in the Lee Innovation Lab.
