Technology Firsts

Two of my Technology Firsts.

My first computer technology experience involved buying a Sinclair ZX81 computer, and in a way it was my first technology disappointment. It was a small, light ‘home computer’ that came with 1k of memory (though I did get its 16k expansion pack) and fed its monochrome output to a television. It was, in its own way a fun device to use and could even play a far better game of chess than I ever could. (You try today to get someone to write a fully working chess game using less than 16k of ram!) However what let it down was an awful membrane keyboard, but what really killed it for me was an unreliable program loading and data saving system. The device had no internal storage system so you had to use a domestic cassette deck connecting its headphone and microphone sockets into the side of the ZX81. This was so temperamental and unreliable – getting the cassette player playback and record levels correct, sorting out cassette start and stop routines – it made using the ZX81 a real pain.

I could see that computers were the way to go, so later replaced this with a Commodore VIC-20. What I liked about the Commodore (compared to the then available Sinclair Spectrum) was that the Commodore had a really nice typewriter style keyboard and its own dedicated cassette tape drive for data storage.

Another technology first was my first mobile phone – a Sony CM-R111. This was a wonderful device. It could only do one thing – make phone calls – but I really loved it to bits. A small device which almost fitted in the palm of your hand (at the time when so many were large chunky ‘bricks’) and with a rather novel flip-down microphone. This was at the time when the mobile system was an analogue one, so no text messaging or fancy data systems, just simple phone calls!

Belkin LiveAction Microphone

Last Christmas I was given a present of a Belkin LiveAction microphone, so I thought I’d give it the once over.

On the box it stated that it was for iPhone / iPad type devices, however it uses the standard jack plug that’s common across most devices. It worked without any problems on the two different Samsung phones I have.

It’s about 12 cm / 4.75 inches long, so not that large, but is quite big compared to the size of a phone. If plugged into the phone and you’re using the camera that facing the way the microphone is pointing, then end of the mic may come into view. (Just something to be aware of.)

Once plugged in, there is a small knob to turn that helps to secure the device to the phone. On the side there is a three position switch. Off, close-up directional, long distance ‘super-directional’. It uses a standard AAA size battery.

Over the years, phone manufacturers have spent a lot of time, money and effort in improving their internal microphones. Under standard indoor conditions I didn’t find any huge advantage to using the Belkin. Where it really did come into play was outside. Using its standard directional setting it picked up my voice quite nicely while cutting out (or at least reducing to an acceptable level) most of the other background sounds. At one time I was standing beside a busy road where the level of traffic noise was such that if I was talking to somebody standing beside me I’d have had to shout, however the Belkin picked up my speech nicely. I can see this having some potential in a gig or live event type situation where you want the sound from the stage while minimising the noise from the crowd beside you.

Using it switched to its super-directional mode it did pick up speech from quite a few metres / yards away. The quality of sound was not particularly good, however I’d rather have some sound that may be poor but I can work with that no sound at all! I can’t see myself using it in this mode very much, though I guess it’s handy to have there.

Overall I rather like it. With phone video quality improving more and more people are using this function when out and about, and under difficult conditions this Belkin does do a better job than the phone’s internal microphone. It does however still pick up wind noise, I must look out for a windshield / dead cat screen for it.
