The Wi-Fi® Comm Demo Board combines Microchip’s best-in-class 32-bit PIC32 microcontroller family with its low-power MRF24WB0MA agency-certified, IEEE 802.11, embedded Wi-Fi radio transceiver module. Additionally, Microchip provides a free and full-featured TCP/IP stack, which is available today for download at www.microchip.com/TCPIP. This compact and cost-effective demo board is easy to integrate with existing embedded designs, to evaluate Wi-Fi connectivity and 32-bit performance with minimal effort.

An Arduino being used to measure the speed of a 12V computer fan. An IR light emitter and photodetector are placed on either side of the fan. As the fan blades spin, they break the beam of light coming from the IR emitter from being seen by the detector. By counting how often this happens, we can figure out how fast the fan is spinning. In this picture, the LCD display says the fan is spinning at approximately 5040 RPM. This was programmed in C++.
This project was interesting because it is a very direct way to see how fast computers really are. The fan is spinning so fast that it just looks like a blur to the human eye, but even this tiny, not-so-powerful microcontroller had no problem keeping up with it and counting the rotations. Very cool.

Microchip announced a new series within its high-performance PIC32MZ family of 32-bit microcontrollers (MCUs) that features an integrated hardware floating point unit (FPU) for high performance and lower latency in intensive single and double-precision math applications. This new 48-member PIC32MZ EF series also offers a 12-bit, 18 MSPS analog-to-digital converter (ADC) for a wide array of high-speed, wide-bandwidth applications. Additionally, the PIC32MZ EF supports an extensive DSP instruction set. This combination of DSP instructions, a double-precision FPU and a high-speed ADC improves code density, decreases latency and accelerates performance in process-intensive applications.

Microchip expanded its eXtreme Low Power (XLP) PIC® microcontroller (MCU) portfolio. Features of the new PIC24F “GB4” family include an integrated hardware crypto engine with both OTP and Key RAM options for secure key storage, up to 256 KB of Flash memory and a direct drive for segmented LCD displays, in 64-, 100- or 121-pin packages. Dual-partition Flash with Live Update capability allows the devices to hold two independent software applications, and permits the simultaneous programming of one partition while executing application code from the other. These advanced features make the PIC24F “GB4” family ideal for designers of industrial, computer, medical/fitness and portable applications that require secure data transfer and storage, and a long battery life.

Microchip announced the industry’s most comprehensive 32-bit microcontroller firmware development framework—MPLAB® Harmony. This framework is the first to integrate the licensing, resale and support of both Microchip and third-party middleware, drivers, libraries and real-time operating systems. Currently, Harmony includes third-party offerings from Interniche, freeRTOS, wolfSSL and OpenRTOS, with many more on the way. The result is that developers can greatly simplify their PIC32 MCU code development process by reducing common integration bugs, thus accelerating time to market.

Jeremie, the brains behind the SB-FireFly, has been hard at work on some hacks for it that incorporate a Piezo buzzer. Get the details here.
Electronic Pornography - The "business side" of my Peak Electronics ESR60 Capacitor Analyser
People who are clever at programming microcontrollers - in this case a PIC can really make them sing and dance and jump through hoops.
This instrument is a very good example of that skill (or is it art?!)
I'm also becoming increasingly impressed with the little Canon Powershot SX260 camera I used to take this picture.

The manufacturer has recently (Jan 2014) upgraded the firmware and probe set at a very reasonable cost. One little gripe I had with the operating convenience of this unit was that sometimes three hands were required - two to hold the test leads onto the component, and a third to operate the "test" button. This has been addressed with the later version of the firmware. The company also turned the unit around extremely quickly, and were an absolute pleasure to deal with.

This is the microphone preamp for my simple circuit to display music on a VGA monitor like on an oscilloscope.
It is worth to note that this is not mounted on a PCB, rather I glued some red paper on the perfboard then opened the holes necessary with a needle.

Dorkbot Bristol, December 2008: Richard's Arduino controlling a pair of micro servos (intended for radio-controlled aircraft) as a walking robot. It's simply two servos linked together with cable ties, plus some bent wire for legs. The program in the Arduino sends pulses to the servos that make them walk.
Exploring micro-controllers with the Arduino NG development system. Seen here running in standalone mode with a 9v battery. Arduino makes embedded programming fun and easy by bringing together a clean and simple hardware and software development environment.
Here, I'm messing with reading analog input from a 10k potentiometer and PWM (pulse width modulation) of leds to produce variable brightness.

www.arduino.cc/ - "Arduino is an open-source physical computing platform based on a simple i/o board, and a development environment for writing Arduino software. The Arduino programming language is an implementation of Wiring, itself built on Processing."
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.

Two 1960s-era moving-coil meters, with one of them rigged up to a DAC (digital-to-analog converter) on the Arduino. The meter movement was rated at 1.4mA, full-scale. I'm using a 2.2kΩ resistor to produce that current from the 4.096V output of the DAC.
I'm getting a Lily Pad wearable open source arduino microcontroller in the mail soon and i can't wait to get going with it!
