Bats Updated.

As there are 75 species of Bats in Southern Africa and only 20 that are insect eaters it should be easy to find which type these bats are. Unfortunatelly on the South African website for bats it doesnt give too much info for the layman. Having compared my pictures with some thumbnails on the web I think I know which kind they are. If anyone can give me any info please email me. whitewolf1@live.fr

I am still trying to get some really close bat pictures but my flash is still not fireing at the right time. At the moment it has become very random. Last night I took another 40 pics and got these 2.

Looking at some pics found on the web I can see that they are Pipestial bats.

Bats in my Hair?

bat2bat1

Well thats just a myth. Sitting in my garden at night I noticed that whatever was swooping around my garden made a clicking sound. On pluging a mic into the laptop and feeding this through a sound editor I realised they were Bats. I compared these sounds and presume they are Pipestal Bats and are eating insects. I wodered why I had no mosquitoes biting me on the stoep.

I think they came out very light because I was using a flash. I had to take 30 photo`s to get these two. This night photo taking started with the unusual pics I got in my earlier blog. I don`t think it was Bat Breath.:=))

UFO and VLF Detector.


This circuit is very simple and can be used for many purposes. I have tranfered this info by photographing part of my notebook. This and other info was requested by SAUFOR several years ago for a lecture they were giving. I do not believe in little green men or flying suasers. I have scanned and photographed the skys for many years and seen a lot of unusual things, but have yet to prove any sightings of alien craft. I have however sent photographs to NICAP in the USA which they have certified as authentic. These photo`s I tried to get publish here in the Cape Times and was told that the CISR would not let them do so. They kept the prints and the copies of the negatives and I never heard from them again. The pictures can be seen here. And part 2 here

Wardriving Laptop power supply.

comp-setup11

With the problems of power cuts and downtime from Telkom I have been forced to drive round to find free hotspots. The trouble was that with my reasonably new computer I did not get more than a 1 hour stint on the Net.

The reason why many Laptop batteries do not hold their change is because they are never allowed to be drained flat by either going for a drive or switching off the power supply until the laptop switches off.

The best thing to do is remove the battery pack when very low and leave it out of the computer for a few days. During this time your laptop works as normal without its battery. After a few days your battery will have gone flat, you can then fully charge it by putting it back in the laptop.

If the battery is removed my “Sony” laptop works very well between 14.5-18.5v dc. The start-up voltage is around 19v . I tried this with the original battery in the laptop and it drew 4.5Amps, with the battery removed it drew mostly 1.09- 1.8Amps. This was when it was being used with a WiFi dongle. In extreme cases when more than one application was being used the amperage drawn went up to 2.4amps for a short while. I have tried it for 2 hours and have no adverse effects. The advantage of using the charger input is that you get full screen brightness and all functions as if using the mains. This method is much cheaper than a DC -DC power supply that drain the battery when not using the engine. I have driven with this setup and found that it does prolong the time I can use the computer on line around town.

The way I got the voltage was joining a 6 volt battery in line with my car battery, using a cigarette lighter plug. The wire carrying the DC plug for the laptop was cut and another plug and socket added. I can now use this with the laptop power supply or the battery version in my car.

I will put all the photo`s on this blog latter in case anyone is interested. Or I can email them to you. whitewolf1@live.fr

All photo`s and text will be on the Webpage first.

The Fly Gun, South Africa.

instr1instr2

Have you ever wondered if there was a gun to shoot flies. I one made one like a miniature shotgun that used plastic caps and sand. Not the sort of thing for around the house.

Below is the original South African invention that took off with a bang, many years ago and has now died. The instructions are on the first two pics. After that comes the unloaded and loaded positions of the original gun. It made quite a lot of noise when a fly was hit against a window or cupboard. Don`t shoot one on a painted wall unless joy want a lot of work cleaning it. It was fun shooting them as they pass by, but you must know the length of the string or it ends up hitting you on the rebound. Try to hit the fly before you have sent all the string towards it.

Things 4 Politicians 2 Wear ?

This was this picture that started it all. It`s for people with runaway mouths and cuts the tongue every time they try to speak. This page was inspired by a comment from Roly. Click 4 his Webpage or Blog.

I was asked to look into things to stop the problems of rape and sexual harassment among politicians. I have searched the net and found these. Now we nead to find a way to make them compulsery in parliament and anywhere they may go.

We have a choice of two, you must decide who, has which one and why.

Hope this is some help, if not we could do it the traditional way, and use a rusty knife.

Christmas Cakes with a Difference.

The saga of the Christmas Cake has come to an end. As can be seen on the last two years cakes my wife likes to amuse the grandkids with unusual cakes at christmas. She has decided to leave off any writing on the cake this year as all they want is the different Santa.

Kids Spearfishing Equiptment ?

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.

Mini Crossbow.

I have made many projects, this being one of the oldest to be found in the junk box. It still works and is too powerful to let kids play with it. It was used to fire tooth picks but they were too light and metal arrows (bolts) had to be made. Thick cardboard boxes were used as targets.

School day Codes.

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.

diagramatic_key

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.

diagramatic_msg

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.
