ICONIC - The Ultimate Edition

The new Ultimate Edition of ICONIC is offered in a white Cromwell Aristo Grain clamshell case with a custom PCB designed to pulse an LED embedded inside the case itself. 

The circuit is powered by the high-performance, low-power Atmel 8-bit AVR RISC-based microcontroller which combines 1KB ISP flash memory, 32B SRAM, 4 general purpose I/O lines, 16 general purpose working registers, a 16-bit timer/counter with two PWM channels, internal and external interrupts, programmable watchdog timer with internal oscillator, an internal calibrated oscillator, and 4 software selectable power saving modes.

The Ultimate Edition PCB, designed here in Atlanta together with Flash Automation, uses a very simple circuit to gently pulse the surface mount LED three times after the ball sensors are triggered by movement.

The assembly source code used to flash the Atmel is available for download (edit: I'm having issues uploading to GitHub at the moment - contact me if you want it and I'll email it through - Jonathan).

The board and clamshell were designed to make removal of the board easy for the purpose of enabling and replacing the battery. The battery is a standard watch cell CR2032. Based on our calculations, the LED should pulse approximately 9000 times during the life of an average CR2032. Since the LED pulses three times on each movement cycle, that means that it unless you plan on picking up the book more than 3000 times, the battery should last a long time. But because it's so cool, we think that you might actually reach that number - so we made it very easy to swap out the battery.

Also included are two individual prints and a letter of authenticity from the author. This is a must have for Christmas!
