I used j113 in Phase 90 clone, works just fine.

Short press (400ms or less) - normal latching operation.
If I press and hold button longer then 400 ms, then MCU turns into momentary mode and effect will be switched to bypass on button release

I added relay bypass for my blueshift.
Attiny13a based. Both momentary and latching operations.
Who cares?  ;)

I bought this scope to calibrate bbd choruses, it's working great.

I've tried center negative adapter (accidentally) and there is a diode protection, so nothing were harmed.

I've never tried this, but here is some pc sound card scope info: https://makezine.com/projects/sound-card-oscilloscope/
I used suggested program as a signal generator and this http://www.jyetech.com/Products/LcdScope/e150.php oscilloscope for calibration.

Suggested 8KHz Sine was not very accurate, but 1KHz to 3KHz was perfect.

New I/O jacks configuration. Now it makes sense both horizontally and vertically. Both inputs connected in parallel.

Now I feel that my Blueshift really needs to be rehoused. It's too ugly and big,  compared to others.
But now I'm thinking if this thing could  be biased with PC and soundcard?  Is there any software for this work?

I used standoff that 12 mm long. This just a hair shorter then switches.
Maybe I'll move input jack to the left side of enclosure, but for now it's fine, just conterintuitive when turned horizontally.
Sounds great, biased to 3.4v with multimeter, bl3207/bl3102, minimalist bypass

Well, new plan. Who needs battery anyway....
I decided to do it much simpler.
Everything on a long side
Not a piece of art, but I can't wait to finally hear how it sounds like

Thanks for sharing your thoughs. Battery isn't really necessary.  I tend not to use them anyway. Main reason was that I wasn't able to get 125B and miniature power connector, so I decided to use what was avaliable.

Build Reports / Blueshift DimensionC in 1590BB

Hello!
This is much less interesting then putting this beast in 1590B, but this is how I decided to build it.
I'm going to make it slightly assymetical and battery powered .

Now it almost fully soldered, but not housed yet. I'll post some pictures in a few days

IC3 is not in signal path, it's fine that you can't hear you signal there. Check t1 trimmer and blend and level pots

I've biased my mn3207 to 5.2v on pin 3. Did you try to adjust trimpot?

Just lift one end of R9 and put it to switch

I've tried this. Sounds nothing like slapback anymore, but chorusing very weak and depth pot needs to be set almost at max. Maybe with some LFO tweak it will be good
