Two projects – one conclusion.

A couple of things didn’t happen this week – yes, I know, many trillions of things did happen, but most of them were insignificant in the grand scheme of ‘even-bigger’ things.

First, scientists working with the Large Hadron Collider are starting to admit that the Higgs Boson is an even smaller needle in an even larger [...]

Joe’s Soup Kitchen: 19th Nov. 2010

A stinking cold and sore chest, together with seasonal North-East England weather, brought thoughts of at least one hot, comforting, bowl of tasty soup each day foremost to my mind. Usually this means a ham or gammon shank, loads of dried pulses, onions and carrots. But I decided to do things differently this winter, giving [...]

Digital Kitchen Timer for 79 pence? – Don’t be clucking silly!

Digital Kitchen Timer for 79 pence? – Don't be clucking silly!

Yep. It’s true.

Yep! It's true!

The out-of-packet experience is a very positive one. The unit is housed in a reasonably-tough plastic enclosure, and is light enough to bounce when I drop it on the floor. Setting the timer is a doddle. Use the ‘RESET’ [...]

SAD? Light up your life with my DIY 200 watt mini-sun!

SAD light

After my experience in hospital just over a week ago, the house seemed dull and dark. I partially alleviated the problem in my workshop by mounting a 3-spot fitting over my head. (where I’m sitting typing this) Whilst the 150 watts of georgeous warm light shining down on me is wonderful, it came [...]

The Hairbrush From Hell

Hairbrush From Hell

OK, it’s not from Hell, and you probably wouldn’t like to brush your hair with it. But if there are hairbrushes in Hell, I imagine they would look something like this. Basically it’s a nail sandwich on the end of a stick, which is really useful when laying carpets.

Table-Leg Paper-Towel Holder

Paper-Towel Holder

Even though this item uses almost all re-cycled stuff throughout, it wasn’t built expressly for that reason, rather it came about because I couldn’t find anything that fitted my requirements in the hardware/kitchen stores.

A pair of 1Kg dumbbells will cost you around £6.00, depending where you buy them. My dumbbells cost about 30p. [...]
