The Tech in My Life #5: Home Electronics Kits

When I was 10 or 11, my favourite Christmas present was a Gakken 150 IC-in-1 Home Electronics Kit (model no. 81357).

This Japanese-made toy (marketed via Tandy and RadioShack) gave me a solid education in the fundamentals of electronics: circuits, components, DC and PV power (it had a solar battery), photo-resistance (it had a cadmium sulphide light-sensitive receiver switch), short-range radio transmission and reception. It also had an integrated circuit board, as well as a range of resistors, capacitors, rheostats, relays, tuners, and transformers.

There was even an experiment for making electronic percussion – this involved wrapping some wires around my wrists, and connecting other wires to some pieces of aluminium kitchen foil. By tapping my hands on the foil (and completing the circuit), the resulting sound was like electronic bongos, and not a million miles from the electric drum pads Kraftwerk played during their appearance on BBC TV’s “Tomorrow’s World” in 1975.

This dabbling later led me to dismantling an old television, and repurposing some of the components to make a very rudimentary synthesiser (with bits of tin can for the keyboard) for a school science project.

More importantly, playing with this kit drove my curiosity as to how things work, learning to take them apart and repair them, and triggered an equal frustration with sealed-unit devices and labels saying “no user serviceable parts” inside.

The Tech in My Life #4: Reel-to-Reel Tape Deck 

When I was a kid, my family had a late 1950s/early 1960s Grundig reel-to-reel portable tape deck. I don’t really know why my father bought it, because the only home recordings I can recall were of my siblings and I playing the recorder (badly), and an attempt to tape an episode of Top of The Pops on BBC TV.

Although simple in design, it was actually quite cumbersome to use. The motor and the electronics generated significant machine hum which leaked on to the audio. It was mono, but offered 4 tracks – 2 in each direction – and in theory, it could record overdubs and play both signals back together, if only you could sync the play and record heads. Years later, I used it as a guitar amp, but I could only hear this auxiliary signal if the deck was in “play” or “record” mode – so I would have it on “pause” all the time, which tended to stretch and tear any tape.

Nevertheless, it sparked my life-long interest in tape, which took off when I eventually acquired my own tape deck in the early 1970s. The humble “compact cassette tape”, when combined with a portable record and playback machine, was the way many young people got into making their own music. Not only did these machines often include a built-in radio (vital for recording John Peel sessions on BBC radio 1), they also enabled live overdubbing (and cassette duplicating with twin-deck tape-to-tape functionality). I had a portable cassette player in the early 1980s that had a built-in stereo microphone as well as proper audio inputs for external sources such as guitars, keyboards, microphones and record players. So it was possible to not just make mixtapes but also make your own home recordings, which could sound pretty decent. I even played around with tape loops, and splicing cassettes, but in a pretty amateurish way. A friend had a Tascam 4-track Cassette Portastudio, in the mid-80s, on which I made some demos of my own music.

Cassettes were a way to produce and circulate music cheaply, and there was a cottage industry of bands and labels distributing albums on cassette, via mail order, using small ads in the weekly music papers. (I own an original copy of one such self-released cassette from 1981, which last sold on-line for over US$180.) Less scrupulously, you could go to somewhere like Camden Market on the weekend and buy a tape of a gig you’d been to just a few nights before.

But, with the arrival of read/write CDs, Digital Audio Tape, MiniDiscs and Digital Compact Cassette, the analogue compact cassette fell out of favour in the late 1980s and early 1990s. And then the music industry decided to discontinue most of these newer formats, because of the increased risk of piracy and bootleg recordings.

Yet, the compact cassette still survives today, alongside a renewed interest in tape loops, and the early pioneers of electronic music and musique concrète. New albums and reissues are being released on cassette, and for a number of years there was Cassette Store Day as a sort of adjunct to its bigger vinyl sibling. Stock of new blank cassettes can still be found for sale on-line, and the format has outlived some of those digital successors that suffer from a lack of suitable playback equipment, or software/hardware compatibilities in the digital age.

Even today, in my current music recording setup of MIDI controllers, computers and software like Ableton Live, I use digital plugins based on tape decks, to emulate tape itself, or to replicate early looping effects, or simply to apply some “analogue” limitations to my work.

The Tech in My Life #3: Crystal Radio

The first radio I owned was a cat’s whisker or crystal receiver, housed in a chic red plastic box. The outward appearance suggested space age technology; the inward reality was a primitive but robust design, and represented my first hands-on experience of electronics.

The advantages of this gadget were portability, ease of use (just a single tuning dial), and no need for a battery or external power source.

The downsides were: limited amplification (no built-in speaker, and the audio was via a single ear-piece – no WiFi or bluetooth in those days!); the need to be connected to an external aerial (a long length of copper wire dangling out of my bedroom window); and it only received medium wave radio signals.

But the worlds it opened up were endless. This was the days before BBC Radio One, and the height of pirate radio stations such as Radio Caroline and “wonderful” Radio London. Listening to the sounds of the psychedelic sixties aged 6 or 7 were formative years in the development of my musical tastes. And thanks to certain atmospheric conditions I could sometimes hear European stations, which sounded very exotic to my young ears.

The Tech in My Life #2: Goonhilly

After the previous tech-related blog on Telstar, it makes sense to mention Goonhilly, a UK-based satellite dish that has been playing a key role in communications and space exploration for more than 60 years.

Goonhilly received the first trans-Atlantic TV signals transmitted via Telstar, and broadcast them into British homes, in 1962. I was too young at the time to recall seeing those early signs of global communications; but I do remember getting up early in the morning to watch the live broadcasts of the Mexico Olympic Games in 1968, and the Apollo 11 moon landing the following year.

During a family holiday in Cornwall in the mid-1960s, my parents took us on a visit to Goonhilly Downs, including a tour of the satellite tracking station. Of course, it was not really possible to see what the dish was actually doing, but I came away with a small souvenir of this new age of technology.

I was given a short strip of computer punched tape. I had no idea what the holes on this piece of paper meant, or what information they represented. But it felt significant to have hold of this data artefact, which I kept for several years.

After I left high school, one of my first jobs was as an outdoor clerk for a firm of solicitors. This involved spending many hours in the communications room, where among other things, the telex machine was located. The secretaries who sent out telexes from the firm typed the text using a keyboard, and the message came out as a series of holes punched into similar paper tape. The tape was fed back into the machine to play it at a higher speed than could be humanly typed, to transmit the recorded message. Even though faxes were becoming more popular, the legal profession still used telex, not only for speed and for long distance communications, but where the record of a telex transmission was required as proof of delivery.

Goonhilly itself is an icon of both technology and culture, and retains a special place for people of my generation – growing up, its name was synonymous with space and communications. And it has been the inspiration for a number of musical tributes, including a concert to celebrate the 50th anniversary of the first moon landing.
