Julian's Home Page at PCBUNN

Thanks for visiting my homepage, even if you arrived here by accident!

I make no apology for the bizarre ordering on this page, which I use mainly as an aide-memoire for myself!

You are looking at my home page. The archived main page for the PCBUNN web server is here. My blog is here.

I am a Member of the Professional Staff and Principal Computational Scientist at Caltech's Center for Data Driven Discovery, a Research Geophysicist with the USGS, and a Fellow of the Institute of Physics. Prior to joining Caltech, I held a staff position as a physicist at CERN in Geneva, Switzerland, where I worked on the CMS and Aleph experiments. Prior to that I was at the Max Planck Institute in Munich, working on the NA24 experiment, followed by a spell working on the UA1 experiment for the Rutherford Appleton Laboratory in Oxford. I have a Ph.D. in Particle Physics from the University of Sheffield, and a B.Sc. in Physics from the University of Manchester.

A proposal from 2009 that incorporates sonification of scientific data, entitled "Audiovisual cueing of significant events in large multivariate science and security datasets".

Pervasive Computing for Disaster Response

This was an NSF-funded project, in collaboration with UC Irvine and IIT Gandhinagar, India. See the project website here.

The objective of this project is to develop key components of community-based pervasive systems which will allow citizens to respond to disasters.

The Community Seismic Network is a related project.

Sandra Fang, a Caltech SURF student in 2012, built a "Home Hazard Weather Station" - check out her blog here. This is a photo of the completed prototype, which contains sensors for dangerous gasses such as CO and LPG, acceleration, barometric pressure, humidity, sound, light, and radiation (using a Geiger counter).

Judy Mou, a Caltech CS student, is now building a situation awareness Android app for a tablet and/or Google TV, that takes the sensor data from the Hazard Weather Station and combines it with a dynamically updated collection of regional environmental, hazard and news information.

There is a SURF Announcement of Opportunity to work on this project in 2013.

Old MWPC Data from Georges Charpak

In the late 80s, when I was a junior member of staff at CERN in the computing division, I worked briefly on some multiwire proportional chamber (MWPC) data that Georges Charpak needed to have rendered as graphics. I used an Apollo workstation (See http://en.wikipedia.org/wiki/Apollo_Computer) running in "borrowed mode" (whereby the application had access to the whole screen of the device). Charpak's data was of the head, chest and pelvis of one (or more?) patients, and came in three files: heglo1, kulin1, and tihon2. I do not recall what these names signified. I can remember Charpak getting quite excited when he saw the images! These data may possibly have some historical significance (I have been unable to find an email address for Charpak to ask him), so I have zipped them up, together with example Fortran code I wrote for decoding them, in the archive here for posterity.

My Nixie tube clock.

I found a nice little box to put it in in a shop in France. The biggest challenge was drilling the required 1" diameter holes (I ended up using a Forstner bit). Here are the guts:

At the top left hand corner is the power supply, which produces 250V DC regulated no load. Underneath is the clock board, which uses a programmed PIC to generate the required signals for the tubes. Then you see the four tubes at the bottom, with the cathode wires and multiplex anode feed wires attaching them to the clock board. There are also two LEDs, in the centre of the tubes, one of which flashes seconds, the other flashes half seconds. The two switches in the top right hand corner are used to set the time and control the brightness of the tubes.



Here is the completed clock as installed in the sitting room, next to an old writing cabinet.

I can't tell you how much fun making this clock was, and what a pleasure it is to see the warm glow of the Nixies telling the correct time :-)

I think I inherited my interest in electronics, radios, scopes etc. from my Dad, who is also a physicist.

My Dad and I went to buy my first scope from a surplus shop in South London ... when we got there, they had about a dozen ex-Navy Solartron scopes for sale. Of course, we only wanted one, and my Dad started going through each of them testing all the functions. By the time he got to the last one, we realised that not one of them was in perfect working condition: each had something that didn't work.

However, the guy who owned the shop had one on his bench, the one he was using. My Dad said "Well, what about *that* one?!". Of course it worked perfectly, and that was the one I ended up with.

But the real event that started my electronics interest off was buying an ex-GPO amplifier box from a surplus stall on St.Albans market. I have no idea why I bought it, or how little I paid, but when I got it home and opened it up, I was fascinated by all the little components, transistors, resistors, capacitors. It also had lots of knobs on it ... and I think this is a key attraction ... anything with a lot of knobs is by inherently very interesting. Because I wanted to know how the amplifier worked, I wrote a letter (I suppose I was about 12 years old) to the GPO. I told them the number on the box, said I wanted some details, and waited for a reply.

A week or so later, a GPO post office van pulled up outside our house, and a postman came down the drive carrying an envelope. Inside was a letter from a Mr. Betton, and attached to the letter was the circuit diagram for the amplifier. I still have it. Even more wonderful: the postman returned to the van, opened up the back door, and fetched out a pile of Practical Wireless and Practical Electronics magazines, tied up in string, which he then gave to me. I still have all those magazines, dating from the early 60s through to the early 70s. A gift from Mr. Betton, who said he had no further use for them, and thought I might like them. That sort of helpful benevolence is a wonderful thing.

My Single Ended Stereo Tube Amplifier.

Uses a 6SN7GT as a pre-amp, and doubled-up 6GF7A triodes as the power stage.

More details, including schematic, here.

A spectrum analyzer I made in about 1990.

It was built for 220 Volts mains, and included a 9V rectifier.

The wiring is what I would call "Boutique", as you can see from this photo:

The audio input is fanned out into five separate bandpass filters of my own design. Each filter is based around a 741 opamp, and tuned to a different frequency from the rest. The output from each filter is fed to a set of five LM341 LED driver ICs which each turn a bank of 10 LEDs on depending on the output level. The 341 can run in two modes: the first mode lights just the LED corresponding to the output voltage, the second lights that LED and all below it. I had a switch to select between the two.

In this image the LEDs are in the second mode, and the Analyzer is responding to a 5kHz sine wave input.










My design had several flaws, most serious was that there was interference between the lowest two banks of LEDs. I think the filters are very wide, and I was too ambitious in tuning their centre frequencies. The result is that, for low frequency inputs, the lowest LED banks oscillate in brightness.

Precision Tube Testers

A web page devoted to the various models of Tube Testers made by the Precision Apparatus Corporation, who were eventually bought up by B&K Instruments

Here's a picture of my Precision 660 ... this is different from all other 660s I've seen in that it has more transistor and tube sockets. I refurbished the case, since the original cloth-like covering was very tatty. To do this I removed all the material, sanded down the surfaces, and applied three coats of Danish Oil.

Solartron Oscilloscope

This is a pic of a Solartron 'scope identical to one I had as a boy. I believe these were used by the British Navy. I cannot recall the model number, but it was perhaps an OS-20?

My dad and I drove down to Dartford (South London) to buy it. When we arrived, the guy had around six for sale, and another he was using on his workbench for himself. My dad and I checked each of the
others, and none of them worked properly, so we ended up with the one the guy was using (we'd come a long way, and I think he was a bit sheepish about how the rest didn't work)!

MJS Sweep Marker Generator

Hewlett Packard 608C VHF Signal Generator

Above picture shows the generator as received. Below shows the generator after repainting, face cleaning etc.

Look at the engineering inside (there are several belts and pulleys)

I checked the performance using my Leader digital frequency meter: the 608C produces beautiful sine waves and is accurate up to at least 90Mhz (the limit of the Leader). The front panel meters correctly show the modulation and output signal levels. Somebody said that by using the analogue modulation input on the 608C it would be possible to broadcast video to a nearby TV!

The manual for the 608D (very similar to the 608C, but features a crystal marker) is here.

Of Historical Interest

Here is a programme of work document for CERN's ECP/PT Group, dated August 1990, drafted by Paolo Palazzi, and containing a contribution from (amongst others) R. Cailliau proposing a new project on "HYPERTEXT / HYPERMEDIA". This was to later turn into the World Wide Web. Of note is that this document pre-dates the official birth date of the world wide web, which seems to be pinned at November 1990 ...  The PT group never really got off the ground, although I do remember a very convivial set of meetings that took place in a good Auberge in the Jura. The relevant section follows:


Hypertext is a form of information storage that is a web of interconnected nodes. The nodes contain information of some kind (document, program, picture, sound, ...), the web lines are ways of getting from one node to another. Searching in hypertext is aided by various mechanisms, each of different speed and efficiency (there can be indexes and keyword lists). However, the user can also navigate by following paths or just hopping along existing links in a random manner. Thus there are no restrictions on how a node of information is reached (in more classical systems one usually has to know part of the location of the information). In addition, users can construct their own additions to the set of links. The information nodes reside on different machines, the links across machines are handled by hypertext servers resident in the machines.

In the context of LHC practically all information will have been generated by machine. However, there is no unified way of accessing this information by machione: different platforms are used and different formats have been used to create the documents. Hypertext seems at the right stage of maturity to introduce it as the unification of these otherwise incompatible sources of data.

The pilot project would aim at giving a minimum level of access to LHC related information from any workstation. No attempt would be made to implement a large range of features, thus one would not provide uniform access to bitmapped pictures on all platforms, or to fully formatted text, since the formats for pixels, character fonts etc. are too divergent on different systems. However, one would attempt to provide
for a small number of the most popular formats, and just use plain alphanumeric text in other cases. This is the only road to success.

Phases are:

- look at commercial products & get educated,

- select the level of services that can reasonably be implemented and the platforms on which they would be provided,

- buy all components that can be bought,

- integrate,

- populate.

Population should be done by incorporating existing documents only. The first phase takes about 6 months.

The introduction of this technique cannot be done in isolation for one project: it has to be done in conjunction with other services and groups such as CN, the administration of CERN, and the accelerator divisions. Technical details of the project are to be found in a proposal by T. Berners-Lee of CN, with whom I would work closely."

CERN's first "Computer" ... the incredible Wim Klein. Here is an extract (kindly provided from the CERN Archives by Miguel Marquina) from a demonstration of Klein in action, taken from his official retirement show at CERN, December 10th. 1976. (There is some more information about Wim Klein here.)

This is an amusing story I was told about Klein. I have no idea if it's true, or not.

An HP salesman came to CERN with one of HP's very first digital calculators, which were exciting a lot of interest in the science community at the time The DG himself arranged a demonstration, and invited
all the Directorate. The room was very crowded. The HP guy set up the machine, and when he was ready, asked the audience for two many-digit numbers to multiply together. Wim Klein had meanwhile come into the room unnoticed, wondering what the crowd was looking at. Somebody suggested a couple of large numbers, and the HP guy started to key them in to the calculator. And before he'd even finished keying, Wim Klein shouted out the answer from the back of the room!
