Some build pics of the Herbs & Stone module.
This is from a company in Italy called Liquid foam.
It's a monophonic analog "groove box" that revolves around a dual sequencer designed to encourage complex pattern exploration
This version uses uses bananas, though there is a 3.5mm jack version.
The panel size is neither 3u or 4u. so it wont fit into a euro case (unless you have the eurorack version) or a serge case
Gianluca, the designer, posted a PCB and faceplate to me.
I'll need to find the parts myself., build it, then make a case.
Looks like a straightforward build. I think this is suitable for a beginner.
There are no SMD components. The parts easy to find & are well spaced. etc
Lots of CMOS ICs which I mostly already had in my little store of parts.
What I didn't have was purchased from Tayda & Mouser

+ Here’s a pdf of the manual.
All component values are screen printed on the PCB apart from diodes (1n4148) and NPN transistors (2n3904) which have only a symbol to indicate the component rotation.
The liquid foam uses a 9V power supply. I understand that this version uses a LM7805 regulator. (I found that I was able to power it with an old 6V DC adapter).
The build notes say you can use a LM7809 regulator if you are using a +12V power supply
Get the IC sockets on first.
These are the ICs needed.
cmos:
40106 ... logic Ic ... Hex Schmitt - trigger inverter
4069UB .... hex invertering buffer ,,,unbalanced
4070 .... XOR gate
4040 ...... divider/ripple counter/Binary counter.
4052 ..............Dual 4 channel multiplexer
4053 1x - on order
4015 ..... 8 position shift register.

\----------------------------------
op amps:
lm13700 1x yes
lm358 2x yes
lm324 2x yes
----------------------------------------
diodes (1n4148) and NPN transistors (2n3904) ..
solder these on next .
----------------------------
Resistors next
-------------------------------
Capacitors.... longer lead into square hole.
The white half is -ve
Voltage regulator:LM 7805
lm7805 (TO-220) or lm7809 (if you use a 12VDC PSU)
Surface components are mounted.
next push in the ICS... into their sockets
TThe Pots go on the other side of the PCB, as do the LEDs.
Its wonderful when everything just works the first time.
