I have been using computers from the earliest days of home computers or personal computers, you know the days of the Sinclair ZX81, or the Commodore VC20, Apple IIe, etc. Actually my first real computer was an Apple IIe. Before that I programmed TI and HP calculators. Afterwards I had PCs and then Macs and PCs, and now a couple of decades later my house is filled literally with dozens of computing devices from the latest tablets, to old laptops, etc.
Why did we all want to have a computer?...
The Shuber Plates are a flexible accessory to protect your playing cards. Two stainless steal plates together with a special rubber band secure your cards regardless of if you want to protect one card or more than a regular deck of cards.
You can not only protect your cards, but you can also use the Shuber Plates to build a pocket card press. Take two large paper clips of the kind shown below.
Clip one on each short end of the deck enclosed in the Shuber Plates. Then remove the wire handles from...
Over the years I had a couple of pretty lame business cards. You know the kind that your employer issues to you or the ones you print out yourself after an hour of fiddling around with a graphics software. During the last years I did not have a business card. While I am not great at handing out my business card, I do get occasionally asked if I have one, and then I am embarrassed that I don't have one. The most recent such incidence prompted me to get a business card made. But I did not want to...
Cy Endfield was a film director, magician and inventor. Among his many achievements he created a unique chess set which he patented in 1974 in the US (3,806,128). This chess set, which allows one to interlock all back row pieces into a tube for easy storage, was the official FIDE commemorative chess set for the legendary 1972 chess battle between the American chess genius Bobby Fischer and the Russian protege Boris Spassky.
The set was originally made from silver and gilded silver in a limited...

"Twisting the Aces" is one of those rare blockbuster card effects which are easy to do and have a very strong visual effect. It was developed by Dai Vernon and uses the Elmsley Count as its primary move. An exceptional trick like this spawns a lot of variations. Everybody is putting his spin on it. I personally learned a variation by Thomas Hierling from Germany from his New Wave Close-up Magic book. It was one of the first tricks I performed that truly and utterly amazed my audience. Over the years I must have done...

I have been interested in magic squares longer than I have been interested in magic. And I have been interested in magic for a long time. It was actually a close cousin of the magic square, the magic matrix as described by Martin Gardner in one of his mathemagic books, which got me into magic. But that is a story for another day.
In this article I want to explain two simple ways to construct an arbitrary 4x4 magic square.
The easiest method possibleStart out with memorizing...
On October 19th 1994 I created a giant origami model using a square sheet of paper measuring 6.36 meters on each side. Total weight was 5.45 kg. I made the fold inside the largest paper factory in Austria, Leykam Muerzthaler. I used the entire width of the paper the factory manufactured. Just to cut off a perfectly square piece of such a large piece of paper was a challenge.
This happened during my time in Japan. I was exposed to the art of origami and when I returned home for break I wanted...
I decided to combine some of the ideas I found online how to make a cheap non-evaporative air-conditioner. The basic idea is to blow air through ice or cold water to cool it down. The simplest solution is to fill a cooler with ice and have a fan blow air into the cooler and out from another opening comes cooler air. But that simple solution does not provide a lot of air/ice surface for heat exchange. Particularly once the ice starts melting the pool of water reduces the exchange surface and thus...

The mystery around the authorship of The Expert at the Card Table and who S. W. Erdnase really was, has lead to many theories and lots of speculation. In this article I am offering a completely new theory. I call it the Nickname theory. I will also try to develop the case for August Roterberg's involvement, either as the author himself, which I think is unlikely, or his participation on some level, which I think is...
