[JUN12] List of Current Members (with working E-mail) and Old Members. Details include Experience, Interests, and Qualifications.

Officers and Committee Members of the British Amateur Electronics Club Archive.
Mr. George Burton, Chairman and Hon. Editor (retired) prontaprint.bristol*cableinet.co.uk When contacting George it is best to include "For the attention of George Burton" in the E-mail title as this is his work address and probably used by other people as well. Sadly Prontaprint seems to have shut down. Perhaps it was too expensive. It gave a cheap quality service for many types of printing.

[JUN06] Chris D Baragwanath cbara*global.co.za Age: 46 [as of 2006] Beginner: Yes Interests: Automotive Elect. / Time keeping. "My interest in Cars is primarily in the old BMC products and includes the Minor, the Mini, the Mini Moke (mine is No. 281 of the 300 assembled at the BMC Plant in the then Rhodesia, MGB and of the Landies (Series II). Am always interested in any discrete ccts. that can be used in restoring / improving the electrics of this generation of Cars, while keeping them authentic. China is fast becoming a force to reckoned with and notice may of them here in SA. They are the apparent recent cause of an increase in basic metal prices, which for Copper has been 52% in this year. Seems they are buying up the place ! South Africa has a small but steady industry designing and producing electronic Fuel Injection Controllers and ECU's (Engine Control Units or 'Black Boxes'), and exports these extensively. (Bosch is a large customer). These are all based on embedded processors. Have not seen any anything PC based as yet, other than the diagnostics for the ECU's. For cheaper, small Cars I have seen electronic ignition controllers that are probably PIC based. There is also quite a market in 'modified' programs for existing brands of ECU, (i.e. more power or more economy, alcohol based fuels) etc... that seems to do well locally. These modern ECU,s are a b@#$%r to mend ! - Often there are no schematics for them, (only ever given out to 'official' repair depots) and then many of the IC's have 'house numbers' rather than the usual identifying numbers on them. Other IC's are specific to the manufacturer and / or LSI and so difficult ever to get spares for." Country: South Africa (Zuid Afrika in Afrikaans apparently, hence the .za in the E-mail address).

[Added JUN06] H. P. Friedrichs hpf*gainbroadband.com. AC7ZL. Age: ** Beginner: No Computers: Variety Experience: 20+ years experience as electrical engineer practicing a variety of engineering disciplines including Twenty-plus years experience in a variety of engineering functions including technical project/personnel management, hardware/software systems integration, design, implementation and repair of electronic hardware and software, and technical documentation. Fields of activity include computer, instrumentation, automotive, audio, aerospace, medical, and test equipment. Programming languages: Assembler (Z80/64180, Microchip PIC, 8051), C/C++, FORTRAN, Pascal, Python, HTML, Clipper (dBase), SQL, Powerbuilder, DICOM. Operating systems: Linux/Unix, Windows, OS2, DOS, and embedded realtime kernels (RTOS). Hardware: Discrete, chip, and board-level analog, digital, and mixed-signal circuitry. PCB design.

Communications gear including RS-232, 422, broadband and TCP/IP. 3 phase power and cryogenic controls. Avionics test sets and other precision pneumatics. Lasers, motion control electronics. Interests: Electronics, science, engineering, writing, composing/playing music, nature, dogs. Qualifications: BSEE, U.S. EXTRA Class Amateur radio operator, 3 U.S. Patents, Author, 2 books. Not all the processors, protocols, and languages mentioned above were familiar to me. So made a quick scout through the most reliable, informative and free source: http://en.wikipedia.org/ - wikipedia on-line encyclopaedia and turned up the following results: Zilog 64180: a direct successor to the Z80 microprocessor of ZX81 microcomputer fame (released in July 1976), and totally compatable. Has a 16-bit address bus, instead of 8-bit. RS-422 (substitute for the RS-232 over longer cable distances). Data Rates: 10Mbits/s at 12 metres cable length ; 100Kbits/s at 1200 metres cable length. One driver can connect to up to 10 receivers. SQL (Structured Query Language): is the most popular computer language used to create, modify, retrieve and manipulate data from relational database management systems over the internet. PowerBuilder (sometimes abbreviated PB): is a computer application development system. Touted as a Rapid application development (RAD) system, it includes tools for drawing the user interface and reports, and accessing database content. Digital Imaging and Communications in Medicine (DICOM): is a comprehensive set of standards for handling, storing, printing and transmitting information in medical imaging. It includes a file format definition and a network communications protocol. This protocol is an application protocol, it uses TCP/IP to communicate between systems. DICOM files can be exchanged between two entities that have the capability to receive the information - image and patient data - in DICOM format. 8051: a Harvard architecture single chip microcontroller (µC) developed by Intel in 1980 for use in embedded systems. It was extremely popular in the 1980s and early 1990s, but today it has largely been superseded by a vast range of enhanced devices with 8051-compatible processor cores that are manufactured by more than 20 independent manufacturers. It contains Processor (CPU), RAM (128 Bytes), ROM (4 Kbytes), Serial Port, Parallel Port, Interrupt logic, Timer etc. Much more information here: Intel 8051 microcontroller. Books: "The Voice of the Crystal" and "Instruments of Amplification" authored by Mr. H. P. Friedrichs. AC7ZL. Photo gallery links: VOTC Gallery - Pictures of the evolution electronic components from the "The Voice of the Crystal" book. IOA Gallery 1 / IOA Gallery 2 - Pictures of the evolution electronic components from the "Instruments of Amplification" book. More about the Books. The books are available in the UK through Camden at http://www.camdenmin.co.uk/. The suggested retail price of "The Voice of the Crystal" is $14.95 USD and "Instruments of Amplification" is $19.95 USD. A vendor list is here: http://www.hpfriedrichs.com/bks-buyit.htm. Quote: My components are not antiques [described in the books]. They are projects designed to teach the principles of radio/electronics. The devices you saw were constructed with my own two hands within the last few years. Marconi has not touched these instruments...except in spirit. "The Voice of the Crystal" describes the principle behind basic A.M. radio, and then goes on to describe the principles behind capacitors, coils, detectors and headphones. These explanations are accompanied by projects built primarily from garbage can items...screws, a plumbing fitting, an old cigarette lighter, a hank of wire, a cabinet magnet, and so forth. "Instruments of Amplification" introduces the principles of amplification, and then describes a number of experimental amplifying devices including homemade electromechanical amplifiers, several homemade vacuum tubes (valves) and even a couple of experimental homemade transistors.

[JUN06] David Ledgard, BAEC Archive Hon. Webmaster david.ledgard@tiscali.co.uk Has been a member since 1990 (studies permitting). Age: 35 [as of 2006] Beginner: No Experience: Digital Electronics, Programming, Making Printed Circuit Boards, Fault Finding, Electronic Theory, Building Projects in Electronics Magazines, and Computer Interfacing. I have worked on the following kit: Infra-Red Hand-dryers. Electronic Gas Detectors. PIC + Fibre-Optic Loop + Psion Laptop Controller driven Battery Monitoring Equipment. The system used two PICs each to monitor each indidual battery. One got the data, the other transmitted data via an RS-232 optical fibre loop to sucessive batteries terminating at a PSION laptop where stats could be viewed, and warnings given. This set-up was used for critical back-up-battery systems like Banks. Psion SMT Palmtop Computers (note they went from straight from series 3 to series 5 without a 4 as this number is considered unlucky in China). PIC Driven Medical Ventilators. Interests: At present writing Internet Pages, Pascal Programs, and Computer Games including Historical Military/Industrial Scenarios & Interactive Fiction Text Adventures (entered in the 1998 annual IF competition), Interfacing Computers, Church, Gardening, buying and selling on eBay, going out in the Mini Bus. Computers: 1982, £300: Commodore VIC20 - 22 chars./line + 3.5K memory + tape drive but with colour! Games included Amok (killer Robots out to get you), and Bomber (where you are flying a plane and have to bomb all the skyscrapers before to descend to far and crash into them!). I also coded in BASIC: Bat & Ball, and Mines (where you have to balance workers, mine output etc... so you can keep of buying new mines). Also had ROM plug in games cartridges available for games like Galaxian, and Gorf. 1986, £1,000: Amstrad PC1512 (Alan M. Sugar TRADing) PC Clone with x2 5.25 Inch floppy disk drive and monochrome monitor. It had a primitive wordprocessor called wordstar which had about 6 disks that you kept having to change with Spellchecker! Games includes: Chess, Infocom Text Adventures (where you type in commands like GO NORTH, or UNLOCK DOOR WITH KEY... basically a book where you play the central character). Also had Turbo Pascal, a good compiler for it's day (designed by Computer Scientists not Hackers). A lot more classy than BASIC or C (which was cobbled to together by to programmers at Bell Labs to drive the UNIX operating system). See BASIC and Pascal download sections near top of main page. Built some electronic interfaces for it that drove, LED's, 7-segment Displays, Starburst alphanumeric Siemens, A/D converter, and SPO256 Speech Synthesizer. Double sided home made PCB card plugged in motherboard expansion slot, coded addressing to PC Prototype Port. 1990, £300 - no monitor or and only one drive: Commodore Amiga plugged into colour TV with annoying rear connector (or monitor), 512 Kbyte RAM (upgraded to 1 Mbyte), x3 floppy 3.5 Inch external diskdrives, and Icon driven. Also had built in speech synthesizer (what ever happened to computers you could talk to?). Classic games: Sim City, Railroad Tycoon, and Civilization 1. 1995, £1,500 + Interest (from Dixons of course, with extra 5 year cover - at a price! Plus costly monthly payments): Pentium 233 PC, with one 3.5 Inch drive, and a handy CD-ROM. Colour Monitor. DELL DIMENSION 3000 PC with XP, Flat Screen (1024x768), Intel Pentium 4 (80'986) processor, 512 MByte RAM, x5 USB Ports (carry data and power on same cable). Upgrades & Extras: 146 GByte Harddrive (ordered x2 size), 3½ Inch Floppy Disk Drive (1.38 MByte), CD Rewriter (ordered +write), 56K Modem, Word (with Spell Checker), and McFee Firewall & SPAMBlocker (£40/year!). http://www.dell.co.uk/tv, very good value! Basic unit £400 including delivery. Qualifications: 1981-86 Comprehensive School: 'O' Levels (or equivalent, last year to do them in 1986): Computer Studies 'B' (wrote a programme to convert between the Decimal and Roman Numeral number system, try multiplied in Roman Numerals!), Mathematics 'C' (I think I could do better now), Electronics CSE 1 (made a two way intercom out of an electronics magazine on veroboard, with drilled aluminium box cover), Biology CSE 1, Technical Drawing CSE 2 (I didn't revise ;-( )... also studied Metal Work (with lath and blueprints - made a paint scrapper and balancing metal man), Woodwork, Cooking... The school also ran it's own farm as a lot of the pupils went on to work in agriculture (somewhere interesting to go before lessons, now sadly closed). 1986-88 Technical College: 4 Passes, OND Computer Studies (10 Distinctions, 5 Merits, 5 Passes). Computers included the Apple II and BBC Micro. Learn Spreadsheet, Wordprocessors, Databases, Pascal, BBC Assembler, MS-DOS (ripped off from C/PM designed by a Computer Scientist who got NOTHING for his efforts), Maths, Fetch-Execute Processor Cycle (Status Register, Flags: Zero, Carry, Divide-by-Zero error... Accumulator, Programme Counter, ALU - Arithmetic and Logic Unit...). Also COBOL (COmmon Business Oriented Language) designed in 1959 by a Committee of Computer Scientists for the United States Department of Defense. Used by Banks a lot. The old computers had very limited RAM and disk / tape space so most programmes only stored the date as two digits. The 2000 year seemed a very long time away. So many old COBOL programmers had to be recalled from retirement to fix this 'Y2K' problem. Incidentally as there are 1024 bytes in a Kilobyte (not 1000!) Y2K is actually 2048! Also note Psion Laptop computers calculate their date from 1980 in seconds! So they will face a date problem in about 2030 when the maximum number of seconds in reached. They have procedures to convert the zillions of seconds number into year, month, day, hour, minutes, and seconds. 1988-90 Polytechnic: HND Information Technology (11 Distinctions, 4 Merits, 5 Passes). Computers included the Icon driven Apple Mac with Image Writer printer, VAX mainframe (lots of dumb terminals - keyboard and monitor talk to the main computer), and 68000 based processor. Languages included Modula-2 (Pascal with libraries), C, and Z80 & 68000 Assembler. Studied 7 layer networking (RS-232 25-pin D-type serial port: NAQ, AQ, Tx, Rx, Gnd... Parity Bit checks... can use 9-pin, like what drives Dial-up Modems), and packet switching (used by the Internet to divide a big file into small chunks each sent, registered, and reassembled). Programmed RS-232 Serial Link, Spreadsheet, Modem Dialer (goes through all the possible Baud rates until it hits one that gives a recognisable signal). I did the low level stuff in C (which is good for bit twiddling). It was hacked together by two Unix Operating System programmers at Bell labs. Not classy like the languages designed by Computer Scientists. 1991-1994: BEng Electronic & Electrical Engineering (2i Hons.). Algebra, Trig., Advanced Mathematics, Servo-Motor Theory, Robotics... 1998: Two 10 Week Technical College Courses: 'Introduction to the Internet' (E-mail, World Wide Web, History, URL's...) and 'Writing Web Pages', HTML (Hyper-text Mark-up Language used to write webpages)... Most useful.
