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 [...]
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!
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’ [...]
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 [...]

There will be some items that you need to buy, this is unavoidable. So when you do need to purchase anything, consider its’ future use. If the item stores well, it may be a good idea to buy larger quantity packs, as these are inevitably cheaper in the long run. A word of caution here: [...]
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. Most Towel Holders are free standing, and to me that equates not only being moved so that it can’t [...]
Despite their popularity, the importance of dumbbells is often over-looked. With them you can perform basic exercises that will strengthen and tone most major muscle groups. Gym instructors advise you to start with a light-weight pair, then gradually work upwards.
A pair of 1Kg dumbbells will cost you around £6.00, depending where you buy them. My dumbbells cost about 30p. [...]
