This is/was one of my blogs. Just a few bits and pieces - IT, woodwork, metalwork, electronics, DIY, technology articles and anything else I might be currently interested in and get around to documenting.

There might be some broken things because this site was converted roughly from Wordpress to jekyll.

My main area of interest these days is political party innovation which I’m building a project for at oneaction.nz

Now for something completely different….after shelling out for one of these awesome microchip cat doors to be installed I thought I’d DIY the opening in my security mesh door. – As the weather warms up hopefully I’ll get more DIY stuff up here.

Mark the bars you'll need to cut to get make a square just a little bigger than the cat door openingMark the bars you’ll need to cut to get make a square just a little bigger than the cat door opening

Cut where you marked using some hefty bolt cutters - a good excuse to buy tools, it would cost more to get a guy out to do the job, right? For now only cut the bars not the screen.Cut where you marked using some hefty bolt cutters - a good excuse to buy tools, it would cost more to get a guy out to do the job, right?

Make up 2 "picture frames" using mitre saw. The inner dimension should be about the same size as the cat door opening or just slightly bigger. I glued and tacked mine together with small nails.Make up 2 “picture frames” using mitre saw. The inner dimension should be about the same size as the cat door opening or just slightly bigger.
