Cycloids are interesting geometric figures.
info on cycloids (German: Zykloide) can easily be found on Wikipedia
in German and in English:
"A cycloid is the curve defined
by the path of a point on the edge of circular wheel as the
wheel rolls along a straight line.
If we further allow
the line on which the circle rolls to be an arbitrary circle
then we get the epicycloid (circle rolling on outside of another
The picture to the left is such an epicycloid.
This simple little
program can draw a whole lot of them on your Psion.
- Solver for Sheet
a macro for Psion / EPOC ER5 machines to execute a simple solver
function as well as a search for minima or maxima of a given
function for the built in Sheet application. It runs a little
but still much better than doing a trial and error method by
hand. Keywords: Solver, inverse function, "was wäre wenn".
USE: In Sheet, you may have programmed a complicated
function. One cell (called 'target cell') shows the result of
the calculation. Another cell ('cell to be altered') is the
variable that influences the target cell.
1) Search value
mode (Solver mode): The macro determines for you, which value
in the cell to be altered is necessary to get a certain value
(target value) in the target cell.
2) Search Minimum/Maximum
mode: The macro determines for you if your function has a minimum/maximum
value in a given from ... to area. The function is examined
in a defineable number of steps, if a minimum/maximum exists there.

- ROT13 and other simple encryption methods
For a family fun project
I wrote a small macro that encodes any marked text in an application
into the backward (=drawkcab) character sequence. By chance
I heard of ROT13, so I quickly added this as well as ROT5
(for numbers) to the code. Anyone who is interested may use
it - but don't encode any secrets with it - if you really have
to, use at least double ROT13 (: for added security :)
tells us: ROT13 ("ROTate by 13 places", sometimes hyphenated ROT-13,
or lowercase rot13) is a simple Caesar cipher used for obscuring text by
replacing each letter with the letter thirteen places down the alphabet. A becomes N, B
becomes O and so on. The algorithm is used in online forums as a means of hiding joke punchlines, puzzle solutions
... from the casual
glance. ROT13 has been described as the "Usenet equivalent of a magazine printing the answer to a
quiz upside down".

MONSTER5 is a demo program of various
recursive algorithms for generating self-similar objects. You
can select between Recursive Trees, Snowflake, Dragons,
Frond of Fern, the Tower of Hanoi and Langton's Ant. Pertinent
Keywords are: Fractal, Chaos, Self-similarity. The package
is delivered with the OPL code and a mbm graphic, so that you
can experiment with it. You are encouraged to alter the fractal
values in the opl code.

Macro for Psion Route with

There: set map orientation to:

GPSmap2drive keeps the car-mark in the
lower third of the Psion 5mx screen. What is it good for?
Route.app and Citymaps, the car mark is often positioned just
below the upper screen. Then you cannot see the roads ahead
of you.With this macro you can.
All keypresses for Route
IMPORTANT: to quit the macro, you must call it
again, then press 'q'. This unelegant 'feature' I would like to change.
Any help welcome.
Should work for Citymaps as well, but it
is not as necessary since the car mark moves quite fast.

- Psioncloth for dust protection
or click to cover)
Like many other Psion owners, I have
acquired some spare machines for the day when my everyday machine
gives up the ghost. I've found that the spare machines are of
no use when waiting in a drawer for day X. So I went and put
it next to my stationary telephone in the hall, where it serves
well as phone directory, local calendar etc. It is synchronized
with the main machine via EPOCsync (see below).
in the open, dust becomes a problem - but opening and closing
the machine for every lookup is not the thing to do: every Psion
owner must have heard of the wear out problem of the display
cable. So, to prevent it from dust, a friend of mine has made
this very nice Psioncloth from silk and some embroidery. It
shines in different colors depending on the light conditions
- a beautiful piece of art. If anyone is interested in such
a thing of any size and any design, feel free to send me a mail
- I'll forward it to her. She does textile wall pictures and
other stuff, too.
- Selfmade mirror for easy Synchronisation of two EPOC machines
EPOCsync is a great program for synchronising specified folders
and files between two EPOC machines. All you have to do is to
align the infrared eyes of both machines. My spare machine acts
as a stationary phonebook and sits with its back to a wall -
no access to the infrared eye in this position.
So I went
and built a small mirror from an old AOL CD. Probably the best
use I have got from it. Just use your fretsaw (or whatever
you have), cut out two pieces and apply some hot glue to join
them together. From now on: very simple weekly syncing without
having to move the secondary machine.

- How to open a SIEMENS S25 mobile
The SIEMENS S25 was a companion
of my Psion S5/MC218 for a long time. Here are some uncommented
pictures on details of the inner mechanics for eventual repairs. In
my case, some keys stopped working. After opening the casing
the key pad, it worked again.
Open your S25 only if you
have no guarantee for it any more, and if you are a "techie"
kind of a person. This is NOT a simple job. Don't blame me if you
ruin your phone. Read the disclaimer below.
I used to have
several links to instructions on how to open this phone.
Unfortunately, these pages all have disappeared from the net.
