I designed and built an Arduino based shutter speed tester today.

I tested the Leica R4s, Leica M3, Rolleiflex 3.5A (recently CLA'ed) and a sad Rolleicord V.

As expected, the R4s came out best, typically 1 or 2% out from my predicted value. The Recently CLA'ed Rolleiflex was typically 15% too slow.

The M3 and the Rolleicord were way out.

Ingredient for a simple target board: Perfboard, 6-pin DIP header, optional battery box, and two types of 20-pin socket: low cost and zero insertion force.

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.

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."

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 announced a new family of PIC32MX3/4 microcontrollers (MCUs) in 64/16 KB, 256/64 KB and 512/128 KB Flash/Ram configurations. These new MCUs are coupled with comprehensive software and tools from Microchip for designs in connectivity, graphics, digital audio and general-purpose embedded control. The MCUs are an expansion to the popular PIC32MX3/4 series of high-performance 32-bit microcontrollers. They offer higher RAM memory options and higher integration of peripherals at a lower cost. The PIC32MX3/4 feature 28 x 10-bit ADCs and 5 UARTS, 105 DMIPS performance, serial peripherals, graphic-display, capacitive-touch, connectivity and digital audio support.

This was intel's first 8-bit microcontroller, introduced in 1976. In addition to the microprocessor, this chip featured about 1K of EPROM memory - memory that could be set at the factory and remained permanent. If necessary, the developers could erase it by exposure to UV light then re-use it. For this purpose, the package incorporates a crystal lens over the chip, making the whole affair visible to the camera.

This macro photo was taken by holding an 18-55 zoom lens backward in front of the camera body. It was difficult to get good focus but I think this shot actually resolves some of the traces and memory cells.

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.
