I tried writing an #android #application in #AndroidStudio by giving instructions by the integrated #Gemini . After ten minutes of instructions, that appeared very promising, I ended up with an application that crashes at startup, and Gemini entered an infinte loop trying to fix it. I guess the agents are still not able to replace us...

Here's my latest #freeCAD design and printout on my #crealityk1 printer. A bracket for connecting a 80mm fan to cool down a harddrive.

I have recently played around with the #Memileo #brushes in #krita, and though as fantastic as they are, there is something which is bothering me with these brushes and that is the repetitive pattern and lack of randomization. E.g. in the following image from https://www.youtube.com/watch?v=YxMfMSzBaz4&t=332s video you can see the same ridge pattern at different places in the image.

I just published a #micropython #mqtt server and #python client for accessing a remote filesystem on a micropython device by mqtt.

See:

https://github.com/dov/upython-mqtt-file-server

Meanwhile I have used it for uploading photos to my #pimoroni #presto device.

This library solves the "grandma problem" of how to place a photo frame on grandma's mantle piece and push images to it without her interaction.

First time I'm playing around with sniffing USB traffic with a 5 USD, 24 MBit/s logic analyser from AliExpress connected to my desktop running #pulseview. Now I have to figure out what to do with the acquired data.

I have turned my #pimoroni #presto into a digital photoframe. Images are uploaded to it through #MQTT So the pimoroni frame can in principle be placed "anywhere on the internet" with mqtt broker access, and then you can upload images to it from afar.

I plan to publish the code on github in the next few days.

Using #FreeCAD, I designed a cover for my #Pimoroni explorer, which I then printed on my #crealityk1 printer.

Here is my work in progress automatic slide scanner project. There are several #freecad designed parts, some #blender modified parts, an #m5stack controller for my #legonxt motors. Next step is to setup my #canon mirror less camera and automatically scan and download the photos by python #gphoto2 to my #linux host and then process the raw files in #darktable.

I managed to compile #love2d for #arkos on the #R36S. 🙂 My changes are at: https://github.com/dov/love/tree/r36s

I finally wrote a short guide about how to write native programs for the #R36S handheld "game computer" running #ArkOS and plug them into #EmulatorStation. See:

See: https://github.com/dov/r36s-programming

I recently got myself a #R36S box which is really a cute #Linux system. Of course, I had to program it, which was actually quite easy, using either #python or #cpp with #sdl2 . The programs can easily be plugged in to #emulatorstation running on the device. I did the editing using #tramp from #emacs over #SSH Here are some screenshots. I thought about writing a post describing the experience if there is interest.

I wrote a minimal #GPU footprint #STL file viewer using #VulkanSceneGraph. I finally feel that I'm getting the hang of #VSG 🙂

See: https://github.com/vsg-dev/VulkanSceneGraph/discussions/1262#discussioncomment-10379415

I wrote a #shadertoy like program using #VulkanSceneGraph (#vsg). Slowly, slowly, am I starting to understand how to use this awesome library. See: https://github.com/vsg-dev/vsgExamples/pull/314

I created a new repo for a #3dmodel viewer based on #qt and #vulkanscenegraph. We'll see what features I'll add. But blender like view directions, auto reload, and quickly moving between files on the disk by space and backspace are on my short list.

See: https://github.com/dov/qtvsgviewer

I made my first PR for #vulkanscenegraph, or rather for vsgExamples. A gizmo axis that tracks the rotation of the main view.

I just published a short intro to my image and vector viewer #giv. See: https://youtu.be/AD45x79Vqi8

Here's my latest creation with #cadquery and printout with PETG on my #3dprinter . An adapter between my macro lens and an illuminated negative and slide holder. The adapter fixes the alignment, the distance and straight light between the negative and the lens. A small scissor table also helps for the alignment.

I like toys and gadgets. So I got myself a #3dconnexion #spacemouse . Attached is the first program I wrote for it, written in #python #pygtk with #goocanvas. The program lets me control a directed cursor with the space mouse. You have a amazing and fast control, though I still fill that my brain is learning new patterns. I'm sure you could use it for games. Any ideas?

My next planned step is using it for controlling the camera in #vulkanscenegraph.

Here's my latest construction with #cadquery and printed in PETG on my #3dprinting printing #crealityk1 . A bracket for attaching my rear light to my bicycle.

Finally, after a long time, I finished my macro lens to negative scanner adapter, modeled with #cadquery. And I then tried to #3dprint it with PLA my Creality K1 printer. The result was a disaster. Even though I had cleaned the bed and applied glue, did the parts not stick to the plate. I got a terrible spongy texture on the legs (but not on the support structures)! Now I have to figure out what went wrong, before printing again.

There are two things that always fascinated me. One, the graphics language developed in #MetaFont → #MetaPost → #asymptote And second, connecting various libraries from different sources.

With that in mind, here's another proof of concept of an interface for loading asymptote paths expressions into #CadQuery.

I added Cubic Bezier support to #cadquery. I hope to prepare a pull request in a few days.

Here's my latest design in #freecad and printed through #3dprinting on my #ender3v2 . A shower holder for my soap/shower bottle. This is really an example of "scratching your own itch". 🙂

Thanks #BehdadEsfahbod for pointing me to this great article on #opentype font design with #metapost! Perhaps I’ll extend it with a cursive Hebrew version. That would yield a Hebrew color font. I wonder if there are any other Hebrew color fonts? See: https://typoday.in/spk_papers/Santhosh_Thottingal_Typoday2023.pdf

Here's a #lifehack if your #GalaxyBuds2 keep falling out of your ears. Use (swimmer's) wax earplugs as a wedge between the earplug and your outer ear. I use half a plug for each ear. Make sure not to cover the microphones.

Wow, it's amazing the amount of traffic that #pomelo has generated in the last few days since it was announced on #blendernation . Thank you for all the interest. 🙂

One issue that has repeatedly come up is the #svg support. Note that #pomelo currently does not support general svg, but only supports a single svg path. There is not really any technical reason for that and I plan to fix it. Meanwhile, do object-to-path and stroke-to-path before saving the svg graphics.

I just released a new version of #paps including configurable headers and footers! Here is an example that used pango markup and generated a pdf file with paps.

I just reported a a bug in #pango / #gtk that causes my program #paps to insert redundant hyphens when turning source code into pdf. I'm ignoring this bug right now and will still create a new version in the next few days. See: https://gitlab.gnome.org/GNOME/pango/-/issues/725

#gtk I have just recreated my cross compilation environment for compiling my image viewer #giv for windows. See, https://giv.sourceforge.net/giv/.

Cross compiling dcmtk, cfitsio, glm, isn't trivial. 😫
