RColours converts the colour bands commonly found on
resistors into the value of that resistor or it converts a given value into the
colour bands that would be used to represent that value. 3 and 4 band
representations are supported and the user can switch between the two to compare
the result (the value is held constant and the colour bands altered to suit).
The value is displayed or can be entered in the industry
standard 1K2 style. The colours are displayed on a picture of a resistor as well
as being named in the drop-down dialogue boxes that can also be used to select
the colours when converting to the value.
Informative dialogues can be opened to provide explanations
of the tolerance band colours and the temperature coefficient colour-band if it
exists. A help file is also included.
RColours is a freeware: there is nothing to pay in order to get and use it. The
RColours 1.00 free full version has a size of 53 Kilobytes. Only one minute will
be needed to get it on a DSL connection, or up to 2 minutes if you are using a
56k modem to download RColours 1.00.
RColours 1.00 will run on Windows 95 / 98 / Me / 2000 / NT. To run on your
computer, RColours will also need the following system requirements: Any Windows
PC + VBrun300.dll.

I am an Electronic Engineer who has migrated into embedded software (firmware
if you prefer). I have always had an interest in computers and first learned
how to program by taking an evening course whilst still at school. In those
days my programs where punched onto cards then sent away for compiling and
running and I didn't get to see the outcome until a week later. I like to think
that this experience has resulted in a determination to design my programs
carefully and get them right first time, however I'm still human!
for anyone who might be interested.
Here are three programs which I consider suitable for publication on the
Internet. RVal and MailUtil have been the result of my own needs - often the
best reason to write a program. But first, RColours which I have published as
an unashamed advert for RVal
Yes, I'm joining the hoards of people that have written Resistor colour code
convertors - there are even Java convertors for use on-line! What makes mine
different? Firstly it will convert either way; from the colours to the value (as
all of my rivals do) and from the value to the colours. Secondly
it's small, both in terms of program size and in the screen area occupied (neither
of these can be said of some of my rivals!). It supports 3-band and 4-band
representations of the value as well as providing a comprehensive list of
tolerance band colours as well as (the rarer) temperature coefficient band
- New in RColours V1.02:
- The program now behaves correctly on systems where the decimal point
character has been defined as something other than '.'
- User interface colours now obey system colour choice!
This program has been written using Microsoft Visual Basic version 3.0, so it
will run under 16 or 32 bit Windows operating systems (Windows 3.x or Windows 95/98/Me
and NT/2000). It has been tested on Windows 3.1, 95, 98, Me and NT 4.0.
If you do not already have the file "VBRun300.DLL" on your machine (probably
in the "Windows\System" directory) then you will need to obtain a copy from
(226K). If that fails try searching the web for "VBrun300" or
e-mailing me and I'll send you a copy.
RColours is Freeware so no registration is required. If you wish to
Suggest improvements or report any problems
I will be pleased to hear from you.
