Forgot to post last night, grabbed dinner after meetings in Mississippi concluded. Turns out the south knows how to do chicken and waffles.

A few updates. Bought the above Obscura, but returned. Really loved the idea, but less robust than I like (Magrette Regattare being my only automatic reference). Also photography related, Increment Labs is releasing their first watch in a couple weeks with a light meter built in. That’s interesting, though the design is not. Take a look Casio lovers - https://www.increment-labs.com . Hope it succeeds. My Obscura refund money needed to go somewhere (besides the obvious savings), so being an Ohio native and a veteran, Lum-tec Watch Combat Field X5 Titanium 24H incoming. Even bought from a reseller near where I used to bike in high school. Apple Watch holds on the other wrist.

Saw it was your BDay on my mobile, and thought I'd post when I get home....looks like we all forgot! Hope it was a great day, and wish you many many more! BTW: one of my (humorous) pet peeves are people who wish "Happy Belated Birthday." The BIRTHDAY wasn't late, your wish was!! 🤣

Thank you guys! Maybe your information will help me with the problem I've with my CFA3smd in SS mode. Removed feeback resistors from board and wired 50K xicons (at red arrows) from outputs to after 5K resistors at inputs. Now steady bias and zero offset. So far so good. But it's still on the kitchen table.

great work ! glad my post helps and yes total length of feedback loop will affect DC offset from my past experience with my own split board attempt , looks like having some oscillation ?

Crazy to think that the 5th Annual Walk for Belonging is here. I joined the board of directors of Communities of Belonging just before the first walk. They have all been motivating and enriching. Originally called "Second Chance Walk" in 2022, a part of April being Second Chance Month. We rebranded the second year as Walk for Belonging (W4B) - because our charter includes homeless as well as justice impacted. 2024 Crew: 2025 smiles: The 5th Annual Walk for Belonging is back at Green Lake on the 25th of April. (I have a lot to get done in the next week). We worked hard this last year and was able to expanded our board to 7 people, which helps with workloads. We are working to expand to a second house to at least double the number of people we can help. Like last year, grants are pretty far and few between under the current administration, but we are ever grateful to our supporters to provide stable clean and sober housing.

Happy non-non-AI birthday wish

Done as well! Keep up the great work, Mikey.

Agreed, listened to it a couple of days ago.

Reworking my CFA3 for ZF/SS switching. Inspired by ang728's hat board, I designed a split-board version. It works fine with ZF but has issues with SS: R channel: 0.2V offset, fluctuating ±0.1V. L channel: <30mV offset, fluctuating ±0.1V. Bias: Stable. Tried those solutions from previous posts but unsuccessful to solve any issues: -Removed hat board; use original jumpers for ZF/SS. -Added 680pF between B-C of output transistors. -Removed C9, C10 (20pF). -Replaced all PZTA56/06. -Swapped THAT340 / K389-J109 / K170-J74. Changing R171, R211, R272, R322 from 300R(silkscreen) to 600R(schematic) fixed the 0.2V offset, but both channels still fluctuate. Suspecting trace interference, I directly wired the jumpers to SS mode. The fluctuation is gone. So I redesign the hat board. SS resistors(R44, R49) sit on hat boards. SS jumpers and SS resistors are removed from cfp3smt2splitpre. My final result to get stable and low DC offet will be: -Using the hat board -R171, R211, R272, R322 = 600R. -Remove C3, C7, C9, C10 (600pF & 20pF) Thanks ang728, his posts helped me a lot.

Middle Eastern wars just sounded ... better in the 80s.

I think I've lost count of how many Winters I've had this year.
