The Hungarian coat of arms features an iconic cross with two horizontal beams. In Hungarian it’s called “Kettős Kereszt” which translates to “Double Cross”, usually called the Patriarchal cross in English. This cross is present on other emblems around the area of Central and Eastern Europe too and has been featured on the Hungarian coat of arms at least since the reign of King Saint Stephen of Hungary.

Seeing as it’s a Hungarian national holiday today, in memory of the heroes and martyrs of the Hungarian revolution of 1956, everyone has their Hungarian flags out. I decided to do something Hungarian too, while trying out some tools for preparing models for 3D printing. So far I’ve been using Blender, because I have some experience with it, but it’s for creating 3D scenes and although you can use it to design 3D models for printing, it’s not CAD software. This time I tried Autodesk’s web-based program Tinkercad, which although lacking many of the features you’d get in a full-blown CAD program, is plenty enough for me to design simple things like this. Not being a mechanical engineer, I probably wouldn’t even know what features I’m missing!

The program is very intuitive to use. I put a few cubes on the workplane, stretched them out into intersecting rectangular boxes and exported an STL file for printing within minutes. You can see a screenshot of the result above. I also made a version with a hole cut out of the top so you could hang it on a key chain. That turned out to be as easy as putting a cylinder in one of the boxes, stretching it out of the top and bottom box faces and marking it as a “hole” in the model.
After scaling the model down to 30% so it fits on my print bed, the final print came out as shown in this photo. It took less than 10 minutes to print at 30% in-fill and seems pretty rigid. I’ve painted on the red, white and green of the Hungarian flag and will hang this up somewhere, who knows, maybe it’ll even be good for a Christmas decoration. If you’d like to print your own Hungarian cross you can download both of my STL files here:
Very strange. On Thursday, on my way to work I saw a cat in the park being harassed by a crow so I recorded it. Unfortunately the video isn’t very sharp because the animals were far away and I was recording them with my phone. I thought it was really funny, as if the crow had a big problem with the cat being there, meanwhile the cat completely ignores the bird.
Funniest of all, I walked the same route the next day and they were there again doing the exact same thing!
The site is back up on line! For more than a month it’s been down while I transferred it from the Namibian server to a new Hungarian web host and now it’s back. Apologies to anyone who wanted to access the site during this time and thank you for your patience. Now that things are working more or less smoothly I should be able to post some fresh content! 🙂
These are some pictures I took while exploring Dornbirn with my roommate, Svaťa earlier this week. The river is frozen and there’s lots of snow everywhere. Click the thumbnails to see bigger pictures and descriptions.
So, what’s going to be different about your blog this year?

This year I’m going to write something on this blog at least once a week! Last year I wrote a mere 13 posts, an average of just over one a month. During that time a lot of my effort was also focused on moving my blog over from Blogger and on various projects. This year I want to write more, so I’ve put the Post A Week 2012 badge on my site to remind myself and other people. If you’d like to participate too, go get yourself a badge from The Daily Post, let’s see if we can do this!
His blog was a great resource for people who keep things light and get the most out of the technology they have. It has a huge list of software and a wiki too. He used to post very regularly, about once a day, but although the site is still online, he won’t be making any more additions. This was without a doubt my favourite blog, probably the only blog I actually read. I’m not sure I’ll ever write that much on here, I haven’t even written anything for the last 4 months or so, but I somehow hope I can carry on what K. Mandla started and share my useful ideas and information with you.
