Hi,
I'm looking for information about an author (and
a series of magazine articles he wrote in the early
70's concerning analog computers) by the name of
D. Bollen.
The articles might have been published in "a popular
English `do it yourself' electronics magazine called
something like Practical Electronics".
Does anyone have a near complete collection of
Everyday Practical Electronics (EPE) Magazine? Maybe
the magazine has an author's index. Can anyone think
of the name another similar magaazine that fits this
description?
I've been told that these articles contain the
"Full details" of my C180 english analog computer.
Regards,
--Doug
P.S. If you CC me then I don't have to wait until
tomorrow for your reply. :)

Back then, Everyday Electronics and Practical
Electronics were 2 separate
magazines..............
I have a reasonable set of both from 1972-1973 onwards (just about every
issue after 1973, many from 1972, and a few before that). D.Bollen wrote
articles in both magazines, mostly (as you might expect) on analogue
stuff............
What I can't find is any articles on analogue computing. There were a few
pots + 1 amplifier type dedicated analogue computers in said magazines
Thank you very much Tony.
The person that wrote to me said "I would recognize this
computer anywhere.", refering to the picture on my web site:

I have made a guess from date codes that it was built with
1971 parts by Physical & Electronic Laboratories Ltd. But the
writer says that the computer was designed by D. Bollen
"from top to bottom" and was featured in this series of
articles. I wonder if the computer might be a magazine
project kit. That would be a very interesting development.

Right. Well my first step would be to email someone at the magazine. EPE
now own/have merged with just about every other popular electronics mag in
the UK apart from maplin's "Electronics". They seem to be a friendly bunch
from the dealings I've had with them.
Going from the front cover of the latest issue (dropped through my door
just a few days ago) their website is http://www.epemag.wimborne.co.uk/
You also might like to try techdept(a)epemag.wimborne.co.uk
Hope that's of some help to you :&)

The bad news is that contacting them didn't answer
any questions, so I've decided to let this little quest
simmer for awhile.
Sorry but we have no data on PE prior to 1991. I know
there was such a
series but we are unable to provide dates etc.

The good news is this episode got me to thinking about
again about obtaining a copy of Doulas Hartree's 1935
article describing the construction of a Differential
Analyzer using Meccano parts. This time I got up the
courage to email the Manchester Literary and Philosophical
Society directly. They were very helpful and they are
copying and sending me the article at no charge.

I have quite a few copies of Practical Electronics, as well
as some Everyday Electronics. I'll check them out.
I've been told that these articles contain the
"Full details" of my C180 english analog computer.
I remember reading old copies of PE in the school
Electonics Lab, back in 1979. There were articles about
making a quite sophisticated analog robot of the "white
line follower" or "light-seeking" type. The magazines were
old, even then, so I'd suspect a date from the late 1960s.
