Instructions of how to build a rowing machine which generates electricity. An average healthy but non-athlete adult can generate about 100W for extended periods. I row most days for about 20 minutes.

This ebook describes my build, some of the dead ends I ran into, lessons learned, and some additional suggestions and alternatives. I do provide all the details that will allow anybody reasonably handy to build the same or a similar machine. You will find photos, sketches, schematics, links to all components I had to purchase and approximate measurements. However, I will not provide instructions...

A spectator populates a row of a 4x4 square with any four numbers. You fill out the remaining 12 squares in seconds to construct a magic square. Does not require any math.

This has become my favorite impromptu magic square effect, because it is easier than a classic magic square - there is literally no math, unless you consider counting up or down by one math - and it produces a stronger effect with spectators. Thus a win-win all around.

The effect: Take any piece of paper, for example the backside of a restaurant receipt, and draw an empty 4x4 square. Then ask a spectator to fill in any...

You will receive a perpetual Gregorian calendar, covering the years from 1500 - 2299, which is printed on one self-adhesive label of size 2.25" x 4" (54 mm x 100 mm). Below the calendar table are the instructions in three lines of text. If you do not need the instructions simply cut them off.

The sticker fits nicely on a case for a deck of playing cards, with the instruction portion bent over the lower edge. (See the photo.) Thus, the calendar fits without the instructions on the back of a poker-size playing card. The calendar...

To have filament feed out of the spool two screws are loosened so that the cover can freely rotate around the spool. For storage the screws are tightened,...

If your deck is already warped and bent, no problem....

From the introduction:

Anybody who has done a good amount of reading in magic literature will have noticed that some of the biggest gems are hidden in magic magazines and journals. There is a good reason for that. Books typically focus on...

The primary innovation in this model, besides that it is 3D printed, is a screw-needle combination which makes adjusting the depth of the punch a breeze. Simply turn the screw a bit more in or out to set the needle tip deeper or higher. If you have moderately strong fingers you will be able to turn the screw by hand....

Tommy Wonder produced his lock from brass. However, brass is not necessarily the best material for this type of device, because...

The starting design came from Randi Middleton who gave me permission to use it anyway I like. I have made several changes to the design, rounded some corners and edges so that it feels better in the hand. Since I am using a stronger material I also could thin up the walls to make it slimmer and I optimized the tongue shape to maximize the noise. I also improved 3D printability. The biggest change is in my use of materials. The housing...

The stand is 17 cm long, 17 mm high and it has a semi-circular cross section. The depth of the slit is 13 mm - meaning the bottom most 13 mm of a card will be hidden by the stand. The stand is short enough to be carried in an inside jacket pocket. ...

Some card routines, particularly the recently published ones in Sunken Treasury by Nick Conticello require one to remember two key cards. In the heat of performing such an effect these can be forgotten, rendering the trick a failure. This system allows you to easily keep track of one or two or more cards that you want to remember.

There is very little to learn for this system. Reading this manuscript should be enough to put this system to work....

One of the first and most active Erdnase hunters was well-known science writer, puzzle expert, and magician Martin Gardner, who erroneously thought he identified cardshark and murderer Milton Franklin Andrews as being Erdnase. After Andrews many other candidates were proposed, but none had a case strong enough to withstand scrutiny. None wrote like Erdnase, nor had sufficient opportunity, nor even a...

You will get 5 replacement rubber bands. Each rubber band is custom made from a transparent synthetic rubber. They are 0.75" (~2cm) wide. Their flat length is 3.7" (~9 cm). They fit the Shuber Blades perfectly but have also many other uses.

I sometimes use these rubber bands without blades. It doesn't give you the same protection...

Shuber Blades are two sturdy stainless steel plates with size and shape equal to a Poker card. Put one plate at the bottom, the other at the top of your deck and secure everything with the custom rubber band. The plates will protect your cards and keep them flat and clean. You can protect anything from a single card, or small packet...

The day was March 6th 2011 when Werner Miller sent me his Da Capo 3 and Da Capo 4 ebooks. Whenever I receive something from Werner I make time to read it. He has a knack to incorporate new twists and takes, or entirely new principles which stimulate my own grey cells.

Browsing Da Capo 3 I stumbled on an unusual effect which Werner titled “Pointing the Way”. It was first published in 2001 in Club 71. This effect consisted of two parts. One was a printing effect where blank cards were shown, which later had arrows printed on them. This part of the effect was nothing special, the usual...
