@Extelec why a musical tap looper design of course! https://concretedog.blogspot.com/2011/04/new-tap-looper-design.html?m=1
@concretedog ahem thats a 14557 not 14577 video amp

@Extelec doh!

@Extelec I got the 14557B bit right though... its a long time ago!

@concretedog It did prompt the question, I really thought there was an alternate use for the video amp chip i was unaware of

@Extelec oooh 4017 is a beauty. CD40106 hex schmidt was in many ways my 555. Loved a 4011 and a 4040. Cheekily gonna add the motorola mc series 14557B as well!
@concretedog @Extelec 40106 was also the favourite of Ray Wilson of MFOS and I can see how it could be your 555.

@synx508 @concretedog 4011 was my 555

@synx508 @concretedog and this was my bible

@synx508 @concretedog 4011 was my 555
@Extelec @concretedog Weirdly mine was 4047, because my introduction to 4000 series parts was through Tom Duncan's Adventures with Microelectronics, the followup to Adventures with Electronics. I never had the third book, Adventures with Digital Electronics, so I don't know what happened next…
-
Mine was always 4011... closely followed by 4001, 4020 and 4017.
@Extelec I once owned about 10,000 4020s that I'd bought from Bonex for £50, which also meant that I'd cycled the 11 miles home with them on a bike without panniers. It took me years to get rid of them at rallies and still find tubes of them in unexpected places. I still remember the huge box that they were originally in had a hole in it and it would occasionally launch some tubes of 4020s as I cycled home.

@Extelec thinking about it, it must've been more like 2,000, an unmanageable quantity …anyway

@Extelec Duh! 4017 - how else are you going to make LED scrollers?

@Extelec 4011, idk why, I think it was because when I was 11/12 I followed a tutorial that taught how to build a computer out of them; and now I'm here, and here is pretty nice

@Extelec
It was the 4046 PLL for a while then the 4066 Quad switch.
Maybe now the 4069U unbuffered Hex inverter as it can be an amp or osc up to 18V.
Long ago I switched to 74HC logic instead of slow 4000 series. -
@rasteri 4066 quad analogue switch iirc
-
@rasteri @Extelec IIRC 4016 is more amenable to using it in a linear mode but it's a while since I tried. 4066s are used with a PWM control signal in several 1980s and even early 1990s broadcast audio processors, you get a 40dB or so of control range with no meaningful distortion, just add low pass filters on the i/o to get rid of the switching noise and to prevent aliasing.

@Extelec CD4060 crystal oscillator/counter.
