Curvature of the Earth

We all know that the surface of the Earth is curved, but exactly how ‘curvy’ is it?  At what scale do you actually need to start compensating for it in a construction project?  Let’s do some easy math and find out… The Earth is not a sphere — it’s actually an oblate spheroid — but […]

Free Dehumidifier

Air too humid inside your house?  Got mould problems?  Clothes take ages to dry inside during the wet season?  How does a free dehumidifier with zero running costs sound? Most folks don’t know that their ‘frost free fridge’ can easily be hacked to act as a dehumidifier.  As it runs continuously, it can be used […]

Slow ADSL Download Speeds

Got an ADSL connection that’s running slow?  Downloads taking too long?  Wonder if there’s anything you can do to speed things up?  Maybe, maybe not.

Lawn Tractor Oil Filter Tips

If you have a John Deere D125 lawn tractor (aka ride-on mower), or pretty much any of the D-series, and have ever replaced the oil filter, then you’ll know how annoying it can be.  The crux of the problem is that: the ‘proper’ oil filter (the AM125424 for a D125) is a very short filter […]

Grid power is dirty!  It’s polluting the planet!  We should all put solar panels on our roofs, some batteries in the shed, and go off-grid!  For the sake of the children!  Hmmm… Not so fast.

Camping Shower

There are a lot of different camping showers available for folks that want to go camping but don’t want to wash themselves with a towel.  Some have heaters, some have pressure tanks and a lot are ridiculously expensive.  I recently was faced with having to choose between the various options and I ended up grabbing one of […]

Dremel sell a Sharpening Attachment Kit with an attachment for sharpening chainsaw chains.  If you follow the instructions included in the kit you will damage your chain, cause extra wear and tear on your bar and chainsaw, go through more fuel and oil, find cutting more difficult and tiring, have difficulty cutting straight lines, and […]

Internet Radio

I have elderly parents (in their 70s).  They immigrated to Australia (from Finland) nearly half a century ago.  As they get older, their immigrant friends are dying off.  Living in the country, as they do, they are feeling more and more isolated.  Their English is (still) not very good so reading local papers or understanding television news is… […]
