Here's one you've likely never seen before. You can see from the documentation that the design was by Ray Marston and development by Geoff Nicholls. Neither have been referenced here on MATRIXSYNTH. Dick Smith has, however, this is the first post to feature the Drum Synth & Sequencer.

"Vintage Dick Smith branded ETI Project Drum Synth circa 1982. I bought this for $100 for parts not working some time ago, I've since had it professionally restored and offering it for sale. Also included is a buddy seq, which I have not restored as I have plenty of ways to seq. There is paperwork collected and printed off the web to assist if you wish to carry out further restoration, or just muse about being entertained by the past."

"I was cleaning up yesterday, I found my Stylophone 7" demonstration record. Recorded it as 96k mp3s and slapped it up on a very very basic page. A friend has a stylophone for me, but, I haven't gotten it from him yet. When I do, I'll attempt to make a schematic - because I haven't seen one online.

Jaycar Electronics - an Australian electronics company has a Stylophone-like kit you can built - as does Dick Smith Electronics. None of them are as good as the Dr Bohm Hobbytron. The Dr Bohm isn't the same as a real stylophone, though. A real stylophone has a BJT based oscillator, where as the Dr Bohm (and the Jaycar and DSE kits) are all 555 based.

Rolf Harris was quite famous in Australia, and more so, I think, in the UK. He was from Bassendean - a pretty dreary suburb in Perth (where the sadly defunct Casio featuring band Turnstyle were from). He had a kids TV Show in the 70s. He recently painted the most up to date official portrait of Queen Elizabeth II.

An inside picture of one here.

My LP recording is here.

The "Vibrato" on a Stylophone actually lengthens one side of the rectangle wave, not both sides, so, it is Vibrato, but, it is also Pulse Width Modulation. My friend Robin Whittle found this out when he hooked his stylophone up to his oscilloscope.
