Pen Replacement

I wrote with a ballpoint pen for many years. My favourite is the Uniball Eye fine (=0.7mm) permanent and waterproof. My favourite colour is wine red - dark and highly visible for marking up engineering drawings.

A warning though do not take it on plane - the change in air pressure causes the ink to leak out. If the cap is on it will fill with ink - permanent and waterproof.

In grade 8, the Canadian teacher did not understand that biro was the Australian term for a pen, after the inventor.

In order to reduce my use of plastic, I am saving my remaining pens for special use. For everyday use I am converting back to pencil.

When I started school, the teacher said that my work was far too grubby and that I needed to change from HB pencils to 4H pencils. I used Copperplate 4H  for the rest of my school days.

Now because I like a thick dark line I am using 4B, and 6B pencils.

 

Radiola

 

A friend asked me to look at their radio. The radio was a present from their father for doing well at high school exams, but it no longer worked.

The radio is an AWA Radiola model B24Z first made in 1964. The original power supply was an Eveready 9 volt battery (type 2362), and is no longer available. I tested the radio with a modern 9 volt alkaline battery (6LR61) and it worked very well. So I replaced the battery connectors with new 9 volt snap connectors, I added a cardboard holder for the new battery as it was considerably smaller than the original and I installed the new battery.

These radios have great reception with a five inch ferrite rod antenna internal shielding and an all metal front face. They are a great collectable radio.

So the radio from 1964 - 57 years ago - works very well. I wonder if anything else that man purchased in 1964 is still in working order.

Colour Matching

 

On Mars the rovers carry colour calibration targets. This allows the images captured to be adjusted to the correct colours depending on the light conditions and the colour response of the cameras.

At my favourite hardware warehouse I found a colour calibration card for use with mobile telephone cameras. It is a card with various colour squares and a grey scale and raised ridges. These characterise the light source and the camera response. In the centre is a hole for the colour to be matched.

The card is stored in a sleeve to protect it from abrasion, staining and fading.

The trademark on this card is Coloursmith and there is a mobile phone app to go with it to produce a colour matched paint.

This card could have applications for recording science.

Line up

 

Long ago I used to put off folding my washing because there were so many tasks to complete. Now I do it very quickly.

One of the changes I made was to make all of my socks the same - it is no trouble to pair them up now. A sock can pair with any other sock. 

Attack

 

It's high summer, my bee hive is under attack. The flies (which are imitating wasps) are laying eggs in crevices hoping that when the maggots hatch they can sneak into the hive.

Tasty

 

I got together with some friends. We all have native bee hives. 

I helped to extract some honey. Then demonstrated how to split a bee hive into two.

We laid out samples of our honey and compared tastes. 
Left     - Sweet with mild flavour
Middle - Well balanced flavour
Right   - Very strong flavour

The reward

 

This is native bee honey harvested from the hive of the previous post.

The hive produced a total of two jars like this, about 1 kg.

The native bee honey is less viscous than european honey bee honey. The taste is sweet with a citrus tang. Like honey bee honey the taste varies with the plants used to make it. Because the honey matures in pods made from a mixture of wax and resin it has favours and substances contributed from the resin. The antimicrobial activity of Tetragonula carbonaria honey has been measured to be higher than the famous Manuka honey.

It is delicious.
