Saving power on your raspberry pi

Most of my Raspberry Pis do one single thing well. Which means that there is probably quite some stuff that can be disabled. For instance, if you use your Pi without a monitor, you can disable the firewire. And if you don’t need an ethernet and don’t need a USB connection, you should disable those. It will save quite some energy.

Shut off your Pi

I guess the number one tip is to shut down your Pi when you don’t need it. For some applications a simple on/off button would work. Here’s a nice, very simple explanation of how to do that.

Disable the USB and Ethernet block

How to set up a headless pi

Download the latest version of Raspbian Lite, which is the version without a desktop environment.

First install Raspbian onto a mini sd card using a tool like Etcher. When the burning is done, mount the drive onto your computer. If we want to access the Raspberry PI using SSH (which we want) we need to add two files to the root of the mounted drive before we can use it in the Pi:

  • A file called ssh with no content.
  • A file called wpa_supplicant.conf which should have your wifi credentials and look something like this (change the country to your country code):
country=NL
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev

Principles of inclusive desin

As found in the book Inclusive Design: Design for the Whole Population These principles seem to be focused on physical products mostly. These principles are described in chapter 19: Universal products in the US. So, to be more accurate, these should probably be called the seven principles of universal design. Even though I’m not sure every life form in the universe will find them equally useful.

Principle one: equitable use

The design is useful and marketable to people with diverse abilities. Guidelines:

Grids op papier, en grids op het web

Tijdens de eerste drie weken van de CMDA Minor Vormgeving hebben we ons naast typografie beziggehouden met grids. Grids zijn, simpel gezegd, hulplijnen die houvast bieden bij het maken van layouts. In deze drie weken hebben we ons de terminologie eigen gemaakt. We hebben een flink aantal verschillende, klassieke grids onderzocht. We hebben ook content geplaatst in drie verschillende soorten grids, op papier. En uiteindelijk hebben we een responsive grid ontworpen voor deze content.

Terminologie

Grids bestaan uit columns. Dat zijn er twee of meer naast elkaar. Veel grids hebben daarnaast ook rows, en dat zijn er meerdere onder elkaar. Zo’n systeem van columns en rows vormt een raster wat bestaat uit een aantal modules: de kleinst mogelijke cellen van een grid. Je kunt content in één zo’n module plaatsen, maar je kan ook meerdere modules samenvoegen tot een spatial zone. Vaak zit er wat ruimte tussen columns en rows. Dat noemen we gutters. De w

The Cleaninglady number 12: georgette, furazolidone and purloiner

Zaire 74 was a three day live music festival that took place on September 22 to 24, 1974 at the 20th of May Stadium in Kinshasa, Zaire

In addition to silk crepe de chine belted jackets with peak lapels, silk/cashmere knit halter tops, pleated skirts and dresses in silk crepe de chine and doublefaced silk georgette in muted colors, there was also a silk/wool bonded silk satin shirt paired with matching skirt and rubber-soled , double-strap sandals made with clear vinyl.
