So you've got your Raspberry Pi, maybe as a Christmas present, and you've followed the Quick Start Guide. You've got a black screen with confusing white text, and you've managed to "login", whatever that means. What do you do now?

There's loads of lists on the net, but they all reiterate the same old examples. Here are some new ones.

Urwin's First Law Of Meetings

The amount of time taken by any meeting is proportional to the square of the number of people attending.

Game Description

Title:The Strange Case Of Miss Trees
Players: 6
Mode: Tabletop

Life at the Carlos Cory School for Gifted Orphans is not a bed of roses; the academic regimen is punishing and the discipline is worse, but once a year you get to go on vacation. Two years ago you visited the school's biggest benefactor, Miss Flaumel, and instead of going to socialite balls, you rescued Miss Trees from a sabre-tooth tiger and a sticky end. Last year you went camping in the national forest, and instead of rock-climbing, white-water rafting and so forth, you defeated a dozen demons and saved the world. It makes a change.

A few months ago you followed the mysterious Misty Reese to spooky castles and strange blue caves, you watched beach vollyball in Hawaii and rescued Marisha from Sven, even if she did not want to be rescued. Oh and then there was the cabal of people who wanted to kill you, and in some cases had already killed your parents. That was quite a wake-up call. Maybe you should do something about that. Miss Flaumel said you shouldn't, but Miss Flaumel is not here, has not visited the school since and, if the recent cuts are anything to go by, has not even been sending funds. And then Miss Trees' last few lessons were taken by a supply teacher. Something, it seems, is up.

After last year’s adventures, Harryn, Skye, Dave and I decided to opt out of the summer camping trip this time around, and as soon as everyone else had left, we started planning where we would go on our holiday. Of course, we weren’t supposed to go anywhere, but we didn’t think anyone would notice we were gone.

A collection of two relays, two diodes, one resistor and a toggle switch to safely power down the RaspPi.

NB. R2 must have a 3.3V coil capable of switching with about 5mA. R1 must be suitable to whatever you are switching.

You should also have reverse-biased diodes in parallel with each relay coil, 1N4001 would probably be good. The lines on the case should be on the side away from GND. A resistor in series with GPIO A is also probably a good idea. 1k would probably be suitable.
