A Rowing Machine which Generates Electricity

by Chris Wasshuber

After I had too much pain in my knees running, I decided to switch to a lower impact exercise. The obvious choice would have been cycling, but I discovered rowing and liked the fact that it trains more muscles, because it also exercises the upper body. I like to be efficient with my exercising. I don't have all day just to exercise. An exercise that engages more of my muscles is therefore more time efficient. It also produces lower joint impact than running. Cycling is even lower impact than rowing,...

The Many Uses of The Shuber Blades

The Shuber Blades are a flexible accessory to protect your playing cards. Two stainless steal blades 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 Blades 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 Blades. Then remove the wire handles from...

Edward Gallaway is S. W. Erdnase

by Chris Wasshuber

To read the full story, the full case why Edward Gallaway is Erdnase, get my ebook The Hunt for Erdnase: and the path to Edward Gallaway.

I know this will come as a shock to some, particularly those who hold on to the old rumor that it was an Andrews. However, this rumor cannot be substantiated. We have to trace this back from Vernon to Sprong to a Drake son who would have to get it from his father who we don't even know had any direct contact with Erdnase. Yet some believe this like it is an irrefutable fact. Let me give you the news, it isn't. It...

Anverdi-type Haunted Card Box

by Chris Wasshuber

In the mid 90s I played around with incorporating electronics into magic. Anverdi had a great idea where a box would close just before a spectator selected card could be placed inside it. I didn't like the mechanics of his box, which was a box for two decks where one half was used for the electronics and the other half for the actual action. The sliding lid of the box would slowly close. Here is a video for the original Anverdi box:

After I read Anverdi's book I could build the variation...

Cy Endfield's Chess Set

by Chris Wasshuber

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.

Largest Origami?

by Chris Wasshuber

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...

Non-Evaporative Cheap Portable Air Conditioning

by Chris Wasshuber

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...

Folding Slingshot

by Chris Wasshuber

As a boy I made many slingshots ever since my father showed me how. Find a y-branching twig, cut it to size, attach rubber bands, and a piece of leather to hold your projectile. I must have made dozens of them. I loved the compactness of a slingshot. I also liked to make bows and arrows but those were not weapons you could put in your pocket. And they were harder to make for a boy. Finding straight arrows was one of the problems. With a slingshot any pebble, cone, or other smallish piece of something...

Bitcoin Mining: A Miners Tale

by Chris Wasshuber

I have been actively mining bitcoins since June 2014. I fell in traps, was scammed, insulted, lost money, made money, learned a lot and have now learned to wrestle the beast that is called 'bitcoin mining'. It is not an easy way to make money. It is also not guaranteed that you will make money. It requires time and effort to get to know all the good and bad, the things to stay away from and the strategies that work. In this article I will share the lessons I learned in the hope to get you up to...
