3D printed a stone

Why? Because i can

While on holiday in New Zealand i made photos of a rock i found on the campsite we where. Nothing special about the rock, but it was a nice subject to try to replicate.

So i took many many pictures of the stone from all sides.

Imported those images in meshroom and convered it to a 3D stl object.

Blender object

Printing and airbrushing

Added some grass from our clock project

Mount Taranaki New Zealand

While traveling New Zealand we went to see Mt Taranaki

Mount Taranaki (Māori: Taranaki Maunga), also known as Mount Egmont, is a dormant stratovolcano in the Taranaki region on the west coast of New Zealand’s North Island. It is the second highest point in the North Island, after Mount Ruapehu.

I made this timelapse using a Nikon D750.

Convert a series of jpgs into a mp4

ffmpeg -f image2 -r 24 -start_number 8296 -i "750_%04d.JPG"  -vcodec libx264 -profile:v high444 -refs 16 -crf 0 -preset ultrafast -vf scale=1920:1080 output.mp4

Working on 8mm film projectors

I’ve got some old 8mm film from my father. And i wanted to digitise them.
Luckily he had some projectors. One was his own and a borrowed one.
Don’t know about the third one.

Not being used for 30+ years, none of them worked.

So i took them apart and tried to fix them.

Most of them had a driving belt issue, and two of them needed a new bulb.

In the end I had three working projectors. Let the digitising begin!

I started off with putting a Nikon camera beside it and selecting 24 frames/second and putting the speed dial just right .. i got a decent recording.

Tips:

Most drive belts still can be bought, sometimes you have to search for an alternative with same dimensions.

Measure the resistance of the power connector. The old transformers could have a shorted connection. (cause: dried out insulation of copper wires)

Use a pressurized can of air to clean the insides.

Keep track of the parts when disassembling. Those things are not made to be easy fixed.

Below a uncut/unaltered recording, so the media needs some cropping!
I love the authentic shutter sound!

Stabilise and speedup movie – Death road Bolivia

This year we spend our vacation in Peru and Bolivia with Arja. (20160606-20160704)

We did the Death road in Bolvia, wellll Arja and me. Coline fell ill the day before.

I tried to get a sense of what it was using a action cam mounted on my helmet and speeding it up in afterprocessing.
Shamefully i have to admit, that most of the times my camera was recording my frontwheel ..

To post: script/program to create this effect

This movie has been stabilized and sped up.

See https://en.wikipedia.org/wiki/Yungas_Road for more information.

Starting at 4700 meters and on the good parts going down @70km/h. Then the dangerous parts started. Feeling like ‘offroad’ narrow corners, where you can expect to see a minivan coming around the corner anytime. Steep drops without barriers. Water and land slides.

(Whole story in dutch)

Us at a bend in the ‘road’

Nikon Lenses

Created a graph for my Nikon lenses. It shows me what lens i can use at what Aperture / Range.

( https://media.henriaanstoot.nl/websites/lenses/ )

It uses canvas to draw lines and text, but thats only interesting for static stuff. ( https://www.w3schools.com/graphics/canvas_drawing.asp )
My example uses a php script to load information from a csv file. And loops though those entries and draw lens info.

Piece of canvas script to draw 17-70mm lens info.

ctx.fillStyle = 'rgba(0, 200, 100, 0.9)';
ctx.lineWidth=2;
ctx.beginPath();
ctx.moveTo(189.98560128675,163.25813588993);
ctx.lineTo(359.81942904592,202.49237972319);
ctx.lineTo(359.81942904592,250);
ctx.lineTo(189.98560128675,250);
ctx.strokeStyle="rgba(0,0,0,0.9)";
ctx.closePath();

ctx.stroke();
ctx.fillStyle = 'rgba(0,0,0,0.9';
ctx.save();
ctx.translate( 189.98560128675,153.25813588993);
ctx.rotate(-Math.PI / 4);
ctx.fillText("17-70mm", 0,0);
ctx.restore();

Making a lot of graphics for a book.

Protographing a bonsai we made (360 we made )

Coline is publishing a book for her thesis.

So we had to design Covers and graphics for this.

I used Scibus to make a mockup design.
The graphics in the book are made using Inkscape.

The book itself was written using Indesign.

Inkscape is perfect to create vector graphics. These can be resized to any resolution. So always perfect.
https://simple.wikipedia.org/wiki/Vector_graphics
In the past i’ve used a program like sodipodi, there is something like it now integrated in Inkscape.
This is a tool to convert bitmap to vector graphics.
(Using a small jpg, i could convert it to vector graphics and print it in a huge size)

Inkscape work


Some designs

Final design

Web controller for Acdsee

UPDATE: 2023 It’s still working

I made a webcontroller for viewing images on a big TV.

Using a Acdsee instance with MCE Controller installed and a webserver.

https://tig.github.io/mcec/example_commands.html

Rate the picture 1-5, clear rating, slideshow start, escape, open/close image, zoom-in out and zoom-reset. Previous and next image fullscreen and delete/yes

Some used defined keys (see php file)

 if ($cmd=="I"){ $put="chars:+"; };
 if ($cmd=="O"){ $put="chars:-"; };
 if ($cmd=="R"){ $put="chars:*"; };
 if ($cmd=="Y"){ $put="chars:y"; };
 if ($cmd=="F"){ $put="chars:f"; };

 if ($cmd=="N"){ $put="right"; };
 if ($cmd=="P"){ $put="left"; };
