About Xinhai Dude 辛亥生

The name Xinhai Dude 辛亥生 is a pun in Chinese, as it means both “he who was born in Xinhai” as well as “he who studies Xinhai”. I had an ambitious plan to write something about the great Xinhai Revolution of 1911, thus my blog https://xinhaidude.com. But after an initial flurry of activities the initiative petered out. One day I will still carry it through. But for now, this website has turned into a conglomerate of my work on various topics of interest to me, including travel pictures, RC model airplane flying, ice skating, classical music composition, science fiction short stories, evolution and atheism.

2018 XiSheng RC Extravaganza 西盛遙控飛行嘉年華

New Taipei RC Flying Extravaganza (西盛遙控飛行嘉年華會慶) organized by NTAMA (新北市航空模型協會) took place on Sunday, Nov 4th, 2018. It was joined by flying enthusiasts from all over Taiwan. I went with friends from the RC club from Kaohsiung 高雄市遙控運動協會, courtesy of 陳振國.

This article hosts pictures I took and edited of this event. Perhaps I’ll come back and finish it with additional descriptions. Perhaps I won’t. It exists for now as a place for enthusiasts to browse and download pictures I took of them, or their planes. I compiled two YouTube videos: a shorter one comprising video clips I took that day, as well as a longer slideshow highlighting some of the many exciting moments I captured in still pictures. As usual, some of the best pictures will eventually end up on Wikimedia. Continue reading

NorCal for the model aeronautically-inclined

This is a guide and a preview to upcoming articles I’ll be publishing, on Northern California through the eyes of a New Yorker, with an inclination to see things from a model aeronautic perspective. It is similar to my model-aeronautic take on Ogunquit and its bipolar beach. Here I’ll examine various Napa Valley and Sonoma vineyards on their applicability to flying, while accompanied by my brother’s family. I’ll show you where to find legitimate flying fields manned by AMA chartered clubs, as well as secret flying places that fanatics frequent. We toured San Francisco, Golden Gate Park, Half Moon Bay, Point Lobos, Fort Ord Dunes State Park and the Monterey Bay Aquarium. Continue reading

Cello sheet music: Adagio from Bach Organ Toccata

Folks, more free Bach cello music can be found in this new article. This is part of the Clean and Free Sheet Music initiative I’ve undertaken.

I took a detour from my usual Bach cello suite transcriptions this time. A few weeks ago someone on Reddit posted a question asking for identification of music. It was a recording of Mstislav Rostropovich playing the cello for the Emperor of Japan, at the White House in 1994. The first piece at 0:37 caught my attention. I swore that I knew this music well – I could hum along ahead of Rostropovich. But I could not recall what this was. The music stuck in my head for days. The mystery drove me crazy.

I tried all sorts of “find the music” magics online, including by singing, by humming, by audio file, by playing on a on-screen keyboard, by entering notes explicitly, and by typing in the contour (shape). Nothing worked. Clearly this was a famous cello piece, but I just could not find it.

Not until I randomly searched for “Rostropovich” and various terms, that I hit the right combination of words. In hindsight, I could have found it in a few minutes, with just “Rostropovich adagio”. So, it turned out that this piece was actually Bach’s organ toccata, BWV 564. Pablo Casals transcribed it for the cello, and apparently it was one of Rostropovich’s favorite piece. Continue reading

What is a Doob 3D Selfie?

Last year my family visited the miniature park, Madurodam. We had ourselves scanned at the Fantasitron, and subsequently our 3D selfies printed by Shapeways. I was so impressed that I wrote an entire article about 3D scanning, stereophotogrammetry and gypsum-based 3D color printing. We have since found another venue for making 3D selfies, this time in New York City. The company, Doob, delivers an impeccable service, starting from the first moment we made an appointment online. This smooth and professional experience extends to email reminders, in-store consulting, and actual 3D scanning. It concludes with flawless 3D-printed figurines delivered to our house.

However, Doob as a company is rather secretive about its scanning process and 3D-reconstruction software. It is almost impossible to find any information about its 3D printing process. Unlike Madurodam and Shapeways, Doob offers no technical details on either its American website, or the English version of its main German website.

Hopefully this article will help answer some of most frequently-asked questions folks may raise, concerning Doob 3D selfies. If you come across this article, make sure you first read the one about Madurodam 3D selfies, to understand the basic concepts. Continue reading

3D selfies made in Fantasitron at Madurodam

Writing a computer program to map 2-dimensional drawings to 3-dimensional models had once been my obsession. This stemmed from the endless hours I spent drawing, by hand, orthographic projections of 3D models, and vice versa. While this was condemned as a chore universally by my classmates at Escuela Técnica No. 28 in Buenos Aires, I quite enjoyed it. After my family moved to New York, I no longer had to make these homework drawings. Instead I wrote a C program to generate 3D polyhedrons from 2D polygonal views. The long paper I wrote alongside this program won the gold medal at the New York Math Fair.

That seemed like a lifetime ago. In between then and now, algorithms had been invented to generate 3D models of people in color and with great details, all from simple 2D photos. But it is only in recent years that such technologies started to become commoditized. Just a month ago, Elisha and I stepped into, for a few seconds, a photo booth the size of a restroom, at the miniature park Madurodam. Three weeks later we received an exquisite 3D selfie printed by Shapeways.

Droning at and around Ogunquit Beach
