Serviceman's Log
11 August 2008
Occasionally, when I am allowed out by myself, I wander off to the auctions for the day. I always enjoy the experience but I have learnt that what you might gain is at the expense of a day's lost wages and if you do buy something, it's often a pig in a poke with no guarantees.

DIY Electrical Work: Are Aussies DUMBER than Kiwis?
05 June 2008
Did you know that it if you want to paint a wall and need to unscrew a power outlet or light switch, you cannot do it legally in any Australian state? Nor can you replace a light switch or power outlet, install a dimmer or ceiling fan. Nor anything else which involves any form of electrical installation, repair or modification. But you can in New Zealand!
