These are a few general observations that might be of interest to some people.
I have always rather enjoyed plugging test equipment into a PC and capturing the readings. Way back in my early days of using GNU/Linux I had a lot of fun with a program called QtDMM. I still have my old £15 bargain-bin Tenma 72-6870 which worked almost flawlessly with QtDMM on Ubuntu, back in 2008….
Firefox running in Debian with KDE Desktop has a rather annoying bug, where it won’t open geo URI links using OSM (OpenStreetMap). This was doubly annoying for me because I have taken a lot of care to include geo URI links in this site recently. Moreover, OSM is by far my preferred mapping service. Anyway,…
I just had quite a busy couple of weeks updating all the tables in our “Reference Tables” section. This is the part of the site where we put all the boring but occasionally useful stuff, such as battery sizes, radio frequencies, internet radio streams and an assortment of other tabulated data that comes in handy…
Another little AI image generation project using Stable Diffusion, via perhance.org. The original idea was to create some fantasy communications receivers as header or “hero” images for our various radio frequencies and internet radio stream pages. My concept was to create well-engineered, expensive, exotic, fantasy communications receivers in retro futuristic settings. However, I got a…
This was a little AI project to create a handful of hero images for our deprecated TV Sound Frequencies pages. Frankly I have mixed views about AI Images. Not least that despite my giving Stable Diffusion very specific instructions, it still managed to make lots of silly mistakes. And the actual televisions don’t bear too…
If you live in the UK and you want decent speed at an affordable price, then you need to establish whether FttP (Fibre to the Premises) is available to your property yet? It’s being rolled out across the country right now. Almost 10 years later than former prime minister Tony Blair said it would. But…
Went to try to photograph today’s solar eclipse. I have to say I’m not 100% happy with the results. The mix of a somewhat unsophisticated lens, and a crude homemade filter resulted in lots of unwanted artefacts on the images. I cleaned up the worst ones in GIMP, but everything else is pretty much SooC…
Found myself on top of Portsdown Hill again today, with its magnificent views over Cosham, Portsmouth, Southsea, the Solent and 13 km+ into the distance, the Isle of wight. Despite the bright sunshine, it was still quite hazy over the conurbation. Still, I was somewhat reassured to discover that our green and pleasant land is…
Sandwiched between the suburban sprawl of Fareham, and a section of the 42 kilometres of perpetual roadworks also known as the M27 motorway, there is, or there will be, Welborne “Garden Village”. At the moment, it’s 405 hectares of grassy hillsides, sparsely peppered with excavators and other builders junk. However, the glossy AI-generated video at…
[Jump to gallery | script] These are some almost SooC images BUT cropped square AND with left and right images swapped AND “alignment circles” at the bottom. These 3D square stereograms were captured with my recently constructed stereo camera module. This is part of an ongoing project to create a modular GNU/Linux digital camera system…
[Jump to Gallery] As part of my embryonic GNU/Linux digital camera project, I recently built a 3D camera module. Basically its a ELP board, in an aluminium 1590A type stomp box with a short internal USB3 extension lead. This is a small collection of processed images I created while I was testing my 3D camera…
I thought it might be handy to make a small collection of web-based resources for outdoor photography and similar activities. Some of these resources are right here on GarfNet. The rest are dotted around the worldwide web. So I thought it would be helpful to list all these links here, all on a single page,…
[Jump to gallery | scripts] This article documents my first experiments in producing red-cyan anaglyphs. The gallery contains of four near-identical 3D anaglyphs with varying amounts of X & Y offset to compensate for the fact that the cameras on the board don’t quite point in the same direction. One can create anaglyphs in GIMP….

I visited the recently rewilded Knepp estate earlier today. Consequently I found myself within 1500 metres or so of Shipley, the location of the infamous Kings Mill. Not to be confused with Kings Mill in Castle Donnington, some 200 km or so north-west of here, this King’s Mill (aka Vincent’s Mill) is a smock windmill…
Today is my wife’s wedding anniversary 🙂 and she has a bit of a penchant for white storks. I think it is a Central European obsession. Anyway, she said we should go visit the white storks at the recently rewilded 1416 hectare Knepp Estate in West Sussex. So I packed my little Lumix DMC-GX7 camera…
[Jump to gallery | script to add exif] These are some unedited 3D SooC (straight out of camera) 1600 x 1200 pixel stereo pairs (3200 x 1200 pixel overall) from my recently constructed stereo camera module. This is part of an ongoing project to create a modular GNU/Linux digital camera system using easily available generic…
Found myself near Cobden bridge, in Southampton, armed with my recently converted , “full spectrum” Lumix DMC-GH2 Micro Four Thirds camera. This was converted just before Christmas 2025 by Protech Photographic in Crowborough. So I thought I would capture some images of Cobden bridge by Infrared… Cobden bridge is a busy road and pedestrian bridge…
Following on from a discussion on a photographic forum who which I belong, an old hobby horse of mine raised its head again. Namely the possibility of building one’s own Debian GNU/Linux digital camera, using Raspberry Pi 5 single-board computer, or similar, and one of the camera modules that’s available for it. Or indeed some…
These are a few infrared snaps using studio lighting. I also took a couple more snaps of my old Wray Stereographic 3D camera. With many thanks to my friend and model Estella Rose who posed for the infrared images in the above gallery.
I suffer dreadful mental blocks at times. I’m also a tad forgetful. To work around this, I use Jaap Karssenberg’s ‘Zim’. This is an excellent indexed, searchable, cross-linkable, exportable, cross-platform note-taking program. Described by its developer as a ‘desktop wiki’ Zim turns effective note-taking from a tedious chore into a simple and routine task. And…
This is the tale of yet another crappy British telecoms provider. On 2025-12-05, I bought and paid for 30GB per month Lebara data SIM card from its Amazon store. But the SIM card Lebara sent was ONLY 25GB. What a con! https://www.amazon.co.uk/dp/B0DQLKFN4H I did not notice that I had been cheated, until it was too…
It was a cold but sunny day today. So I decided to take my “full spectrum” converted camera up to Portsdown Hill for some infrared snaps. I thought it might also be interesting to try it on my 120 year old Bausch & Lomb + Beck 101.6mm lens. Whilst this is not a sharp lens,…
Seems this time it’s Venezuela’s turn to have its infrastructure destroyed and its citizens blown to pieces. Trump claims it’s to stem a drug problem and that President Nicholas Maduro wasn’t fairly elected. Much of the world thinks United States’ Invasion of Venezuela is mostly to satisfy the United States’ insatiable appetite for other people’s…
