PDP-11/HACK edit / delete

Building a minimal -- and I really mean minimal here -- breadboarded PDP-11 system around a J-11 chip. The built-in monitor is pretty cool. I imagine J-11s are even harder to find than HD-6120s, though (although I've wondered for several years about building an SBC around the Russian PDP-11 CPUs...)

Generating random numbers by analogue modular multiplication and feedback. Neat idea. (And should be easy to hack together using a FET-input op-amp and an Arduino board for the FTDI chip...)

Hardware and Firmware Issues in Using Ultra-Low Power MCUs edit / delete

"This report describes the hardware and firmware issues one must consider when designing very low-power coin-cell products." I imagine there are other concerns as well, but lots of interesting stuff here.
