Inside the ALU of the first ARM microprocessor
Dave @ daveshacks.blogspot.co.uk takes a look inside the first ARM microprocessor and explains it's design. With that in mind I embarked on my own attempt to reverse-engineer parts of the armv1. Some background knowledge of the processor's architecture is helpful, and googling for...

Parker Dillmann @ macrofab.com has designed a wrist LED binary clock based on PIC16F527 Microchip mcu. The Macro Watch stemmed from those constraints. I picked the PIC16F527 microcontroller by Microchip to be the core of the watch because it was the cheapest MCU I could find that had...
