From 2019 I am living a more relaxed life. After 35 years I am retired from engineering practice.
You can expect me to mention retirement projects, travel and of course the beloved.
My hobbies may include nature, camping, repair, and reading.

Glasochrom
The Catan Dice Game comes with small marking pads to keep score, but you can get the pdf of the score sheet off the Catan website and print it out full size.
By laminating the pages with plastic (yes I know) I could mark the pages and then re-use them.
I did not want to use a plastic pen to mark them but I found a pencil to do the job - Staedtler Glasochrom.

Be sharp
Of course when writing with my pencil I want a nice sharp line.
I found a sharpener that gives a great point. But it has plastic parts.

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.
