DomipheusLabs has posted part 3 or their “Pi on the Wall” series. This part concerns reducing power consumption.
From the start, I wanted to stretch the boundaries of the Pi On The Wall, and therefore, Raspberry Pi power consumption. It seemed like a rather fun exercise. This post describes what I did in reducing power consumption fairly drastically, given what can be done in this limited power space.
For those who want a jist of what follows: I reduced power requirements of the Raspberry Pi with PiTFT and WiFi drastically. Had to plan for high inrush currents in the designs. Choose switching regulators wisely given voltage and load characteristics. Efficiency varies drastically! Espressos are expensive!
