A simple Moth Trap

There are thought to be over 2500 species of moth in the UK.

Inspired by a friends mercury vapour illuminated Skinner moth trap, I decided to knock up a quick & cheap imitation.

So my design mostly uses bits & pieces that I found in my garage.

I thought our Sony smart TV was suffering from early onset dementia.

It seems to have forgotten how to provide any kind of catch-up tv.

So I've had to look around for alternatives.

Photography: I like manual lenses

Manual lenses can be a lower cost alternative to those that support automatic operation.

The disadvantages are pretty obvious.

But I still prefer to manually set the camera before releasing the shutter.

Hacking my Pentax K to M4/3 lens adapter

Lens adapters that allow you to connect different format lenses to camera bodies can be very handy.

But they ideally need to be the correct length to maintain focus range.

I decided to try to hack an adapter that is just 1mm or so too short.

Using Pentax SLR lenses on a micro four thirds camera

Although we got rid of the majority of our Pentax gear over a year ago, I still have a few lenses.

Since these are just gathering dust, I thought I'd try to put them to use...

...so I bought a lens adapter!

BirdBox2020: it didn't end well

It was shaping up nicely for an interesting bird box season.

Several birds tried our camera nest box for size and some even laid a few eggs.

But with only a week to go before the chicks were due to fledge, it all went tits up!

The Olympus 9mm Body Cap Lens

A lens the size of a camera body cap!

Is it any good?

I guess there is only one way to find out.

Experimenting with Focus Stacking

Focus Stacking is supposed to be a good way to increase the depth of field, especially for macro photography.

In an idle moment I noticed that my camera had a built in mode to help with this.

So here are my notes on focus bracketing and stacking.

Re-discover the Night Sky #3: hot, stuck & dead pixels

Camera image sensors may have faults.

This may result in an incorrect pixel value.

Welcome to the world of hot pixels, stuck pixels & dead pixels!
