I've got a couple of versions of this. .. in banana format and the early metal plate euro format.
The new module is SMD. I understand this is version 5.
"it's 555..." resonator/drone/noise source with CV control of pulse width for all five stages (plus a CV all input)
This module takes an input signal and splits it into clusters of 5 independent pulses. Each pulse can have its width modulated by pot or CV and can be set to any amplitude or even inverted. The pulses are summed together at the output to give a rich strong signal, choc-full of harmonics. It is a very powerful sound that cuts through any mix.
Andrew adds in his build notes:
"this design is based on the Electronotes EN#93 Cascaded Monostable Generalized Resonator.
The main changes from the EN version are that it has been expanded to 5 stages and uses \
larger valued capacitors to allow the pulses to get wide enough to merge with each other and promote mayhem".
So whats a resonator?
According to wikipedia:
"A resonator is a device or system that exhibits resonance or resonant behavior. That is, it naturally oscillates with greater amplitude at some frequencies, called resonant frequencies, than at other frequencies."
You will need five 555 ICs
These are pretty easy to get on. Watch the orientation.
Next are the BCM857
These are bipolar PNP matched transistors
Tricky to get on the pcb , and watch the orientation.
There is a dot on the top left
The BC847s are NPN matched transistors
