Yusynth on Stripboard

[helix_modular]

Dear EMs,

with permission of Yves Usson I intend to share my stripboard layouts of various Yusynth modules. I am very thankful for Mr. Usson's amazing work and I learned a lot in the process of designing the stripboards. Each layout has links to his homepage, after all there is the reference for wiring and the like.

All posted layouts are tested and verified.

A word on my design guidelines:
I tried to maintain a board format that fits behind a 5u standard panel in 'sandwich' configuration, much as the original designs.
The power section is intentionally very generous to be readily adapted to your needs. For my part I use 2x5 Eurorack connectors but feel free to modify. Just make sure these 10Ohm resistors are in series and the caps in parallel and grounded (!).

The provided PDFs are true to size. Print with a ratio of 1:1 and it fits your standard stripboard perfectly!

Feedback is highly welcome and appreciated. Time to give this amazing community something back!

Yusynth Min Max + Inverter (Mod)
http://yusynth.net/Modular/EN/MINMAX/index.html

I've added two simple inverting opamp circuits to 'complete' this module in a sense of analog boolean logic: MIN = AND, MAX = OR, INV = NOT.
Inverter may be easily omitted.

Since you're good at making stripboard layouts you might be able to help out here.

Thanx a lot for this

Yusynth Clock Divider
http://yusynth.net/Modular/EN/DIVIDER/index.html

Modification (suggestion) with reset on rising clock (instead of falling, as in original design) included. Please also refer to this thread:
http://electro-music.com/forum/topic-69933.html

Mounting:
As there's a lot of wiring to be done, I suggest to mount the board in L-configuration. This keeps the wires to the rotary switches short and tidy.

Update (2018-06-05): small image of the reset mod included.

Note (2020-03-29): I recommend to reduce R40 (reset pulldown) to 47k. This amends triggering all outputs at high reset inputs (~ +/-15).

Yusynth Comparators
http://yusynth.net/Modular/EN/COMPARATORS/index.html

Suggestions for different thresholds included. I think this circuit may be simplified in a few places, too (which makes it possible to avoid hookup wires on the board).

Im loving this thread

[artilect99]

Two questions... are any modifications necessary for the clock divider to run on 12V? And 2) does anyone know the what rotary switch is needed (1p12t)?

[helix_modular]

@artilect99

I think the clock divider would work on 12V without modifications. Running Yusynth on 12V is discussed in this thread:

http://electro-music.com/forum/topic-39693.html

However, the tripping voltages for the discrete Schmitt-trigger (input processing stage) are probably a bit off (read: lower, therefore it will trigger at lower threshold). You could play around with the resistor values (R3-R6) if it does not behave as desired. If you feed it a proper pulse there should be no problem anyways.

For the switch: any one pole with up to 10 throws. The original version provides up to divide by 8, the core chip (CD4017) allows up to divide by 10 (as indicated in my upload). A 1p12t switch can probably be configured to lower throws.

Cheers

[artilect99]

Thanks helix. I will try it out and see if it triggers as expected.

Yusynth Saw Animator
http://yusynth.net/Modular/EN/SAWANIM/index.html

I've included standard 1k output protection resistors. If you don't want them, replace them with a jumper or change the position of the output pins.
