My grandson was at a loose end as most kids are on the holidays and asked for some help. He had made a bow and arrow and wanted to go and fish with it. I told him that it was very difficult to shoot a fish when you are out of the water. He then asked what I used when I went skin-diving and I told him I used a spear-gun. Not having the equipment to make one I suggested a very old method that we could make with the things we had. This was the result, using some old bamboo, an elastic band, some string and fishing line and a twig.

For information only.

Another popular system called a diagrammatic cipher, used by many children in school,
substitutes symbols for letters instead of other letters. This system is, in essence,
the same as the letter substitution system, but it’s easier to remember than
26 randomly picked letters. It uses the tic-tac-toe boards and X`s as shown below.

Although when we used it only one tic-tac-toe board and one X was used and two letters were put in the spaces. When tracing the Dan Brown trail some years ago, I found one of his codes was on a similar system . He just used a tic-tac-toe board and put 3 leters in each space. The dot then came in that space to indicate the letter required in that shape.

The same secret message as above, using the line-shapes that surround each letter
(and including a dot where needed) becomes:

Even though it looks like undecipherable outer-space alien text,
this would take an arm-chair cryptologist only about 10 minutes
or less to figure out. Why? Given enough ciphertext, certain patterns become obvious.
Notice how often the empty four-sided box appears: six times out of a total of 29
characters or about 20% of the time.

This would immediately indicate that the empty box
was almost certainly the symbol for “E,” the most frequently used letter in English.
Other letters can also be determined by their frequency and by their association with
other nearby characters (see “Frequencies”). Almost all substitution ciphers are open
to this kind of analysis.

Rudolf Hell. The inventer of ” Hellschreiber”

and the forerunner of the Fax .

Born: 1901 in Bavaria

Died: 2002 in Germany

This man developed a system of communication that is still in use now, although not very well known by a majority of people. It was still used by many Swedish Army personel until the 1960`s, and is still used by amateur radio operators (Hams). I got interested in it many years ago as I like all mechanical devices and have built a printer from his sketches. Since the advent of computers it is much easier to transmit and recieve this form of signal.

The interesting thing is that it prints the letter twice. They are not dots in the original form but dashes, one dot wide and two dots long. this give a resolution of 14×7 instead of 7×7. The 3 has a tail on it so it is not confused with a bad forming of other letters or numbers.

Here are a few links that will explain the system and there are downloads if you wish to try it.

There is a video that can be watched on youtube or on the lower site above. The video is by N4QLB (Ham) the music is “Highway to Hell” by AC/DC, it is interesting and informative. The program can be got from the link above.The download is “Hellsetup.ZIP” and is 972kB.

The link below may not work, but it is on youtube, information is on this page.

It works on my computer.

Brainwaves have been altered in many ways over the centuries using many different methods. Africans and North American Indians have done it with flickering fires and drum beats, usually to obtain a state of excitement and violence associated with a battle. In the East it has been used to cause a religious fervour usually with music and girating.

In the modern era and the advent of electronics it is very easy to alter the brain waves, now we know their frequency. Below is a list of these frequencies and their uses and effects.

There are quite a few ways these waves can be altered, the main being visual and acoustic. The visual method can easilly be done by feeding the output of the brainwave monitor to some LED`s set into a pair of glasses. The acoustic method requires only headphones to be plugged into the monitor. Deap relaxation can be obtained by using the feedback as an indicator to lower your beta waves. Deap trance states can be obtained with training. The reverse can be done by increasing the rate of certain waves to cause excitement. Nausea and vomiting can occure when these waves are taken to the extreme.

Your body is filled with electrical impulses that can be used as communication. This circuit although quite old, still works after 20 years. The gain of this little op amp has a gain of 300,000 which is able to drive a transistor amplifier or radio. It was originally wired straight onto the volume control, but can be fitted with a jack plug and used in the microphone input of any amplifier. Just be careful that there are no high voltages on this input, if possible use a battery operated amplifier. The electrodes are small copper coins with flexible leads soldered on. Sometimes using a piece of cloth soaked in salt water and wrapped around the coin improves the contact.

Placement of the electrodes on the body is important; usually they should be 100 mm apart across a muscle. Contract the muscle and you will hear what sounds like static. To listen to your heart place the electrodes 130 mm apart on either side of your heart.

I also still have the brain wave monitor working, which was an improvement to this circuit with filters for the Alpha and beta waves of the brain.

With the brain wave monitor other filters were fitted on a rotary switch, 5 in all, with the 6^th one used for pulse.

Biofeedback was the next step and a audio output was fed from the monitor through headphones to the subject wearing the electrodes. They were then able to control their beta waves and relax more.

As my DSTV dish is no longer neaded I have decided to use it for WiFi experiments.I started moths ago with a sieve as a reflector to improve my WiFi signal, it has worked very well especially when mobile. Being some distance from the wireless router I am using the signal keeps dropping.

Because I keep loosing the signal I now use this setup with a small sieve as a reflector. In the centre of the sieve I fitted the dongle attached to a USB extension cable. When this was fed into the laptop I had a steady signal. I am now waiting for my local shop to get me a dongle with external antenna fitting then I will experiment with some small hi gain antennas.

This picture of hands was taken with a standard colour film but was not taken by me. Below is a collection of thumbnails of other items photogaphed by this method.

There are several ways to take these photo`s either striaght onto a film emulsion which neads developing or through a clear electrode with a digital camera. I prefer the latter now as getting the film and developing it is too expensive. The reason for this is that a lot of this work is done by trial and error. Years ago when I was interested in this form of investigation film was cheap and easy to obtian. I always did my own developing, printing and enlarging. With the advance it technology its now possible to do the same work at a very small cost and much quicker. Also much fun can be had when they are put on the computer.

Because I have always spent a lot of my time outdoors and usually on the beach or in the bush, sticks have always been part of the equiptment. I have made so many i cannot count them. Most have been given as gifts and are in daily use. This collection goes from swordstick to knobkerry. The one that looks somethning like a hippo`s head was a branch that I found on Muizenberg mountain after the fire some 40 years ago.

The long skull is not finished yet as I want to work on it with my dremmel, to give it teeth.

I used the same mould as I did for the other skull stick, except rotated it so the skull went down the stick,and easier to hold. the other skull I use mostly on the beach as its lighter and very good for moving kelp, to see what is washed up.

I was going through a few school projects and came across this one. It is not very old and is painted on modern handmade papyrus. The picture was traced from a book. The paints were sample tins of acrilic paint and this was sprayed with clear laquer from an aerosol can.
