  1. Joined the "crowds" at Did what it said. Also: (Bonus Points) London And (Water) Lilies. Not shown: People taking selfies with the (Celebrity?) Artwork.
  2. Did a final big shakedown ride before the Marin Metric Century in two weeks. I didn’t want to see the hardest climb (Wilson Hill) for the first time on Fondo day. It was indeed a bear, but I am ready for this. The training has paid off. Should be a fun century. West Marin is pretty damn good riding when you aren’t on the major through roads.
  3. Lately, a few cattle egrets have been wandering around my house.

  6. I’m still working on the above. It’s sort of a known issue (main page image funkiness) but the posted solutions don’t work for the specific issue that we have. I need to join the support forum for the software platform and I’ll see if anyone there can point to an actual solution. What is supposed to work is at the “user level” where if you click your own name at the top of the main page you’ll see a Theme Editor option which is supposed to allow you to be able to configure what you see/don’t see. I haven’t found a way that productively helps with the mobile version of the site and can’t find a way to set a tiny image as the stock forum image so at least the view might condense down while we find a better solution.
  7. This one is for @MexicanDragon - we’ll see if I made a good decision a week from now.
  8. A few years back I discovered a newish country singer named Charlie Crocket. I've become a big fan, and today I went to see him play at Stern Grove Festival in San Francisco. It's an outdoor, kind of natural amphitheater. Nicki Bluhm opened for him and both artists were great. It was a long day but well worth it!
  9. Here are some photos of the SS/ZF switch board I have been using in my CFA3 build. The original SS/ZF switch board, designed by ang728 & vwvwbg, uses a ULN2003 as a relay driver. The mode-control input drives several ULN2003 inputs in parallel. When the control line is high, the corresponding Darlington outputs sink current through the relay coils, so the relays energize. When the control line is low, the ULN2003 outputs turn off and the relays release. The relay coils are tied to +5V, and the ULN2003 provides the low-side switching path to ground. Its COM pin is tied to +5V so the internal clamp diodes handle the relay flyback. I have been using this SS/ZF switch board for about a year and a half without any reliability issues. The only thing I noticed is that switching modes produces a small pop. Even with headphones on it has been acceptable, but recently I started wondering whether this could be improved. . So I added a small Arduino Nano interlock board in front of the existing SS/ZF control input. The Arduino reads the front-panel SS/ZF switch and outputs the required mode-control voltage to the existing ULN2003 relay board. The sequencing is: 1. Detect SS/ZF switch change. 2. Assert mute. 3. Wait briefly. 4. Change the SS/ZF relay control output. 5. Wait for the circuit to settle. 6. Release mute. The mute control is done through a PC817 optocoupler. On the Arduino side, one digital output drives the PC817 LED. On the protector-board side, the PC817 transistor pulls the existing protector MOSFET gate node toward the protector board’s -12V rail. This mimics a fault condition and forces the headphone output protection relay to open during the SS/ZF transition. So the Arduino does not touch the audio signal path. It only sequences the existing relay-control line and temporarily forces the existing KG protector circuit into mute during mode switching. In the installed photo: The top connector goes to the front-panel switch. The switch controls whether Arduino D2 is grounded or left open. The middle-right connector outputs the mode-control signal to my SS/ZF switch PCB. This is the 0V / control / +5V connection. The lower-left connector goes to the KG protector board: one wire to the 2N7000 gate node, and one wire to the -12V output of the 7912 regulator. The lower-right connector is the 5V / 0V power input for the Arduino interlock board. Arduino code attached below: const int SWITCH_PIN = 2; const int MUTE_PIN = 8; const int MODE_PIN = 9; const bool MODE_INVERT = true; // if SS/ZF mode inverted const unsigned long MUTE_BEFORE_SWITCH_MS = 250; const unsigned long SETTLE_AFTER_SWITCH_MS = 700; const unsigned long POWER_ON_MUTE_MS = 1500; const unsigned long DEBOUNCE_MS = 50; bool currentMode; bool readMode() { bool sw = digitalRead(SWITCH_PIN); // HIGH = open, LOW = grounded bool mode = sw; if (MODE_INVERT) mode = !mode; return mode; } void forceMute(bool on) { digitalWrite(MUTE_PIN, on ? HIGH : LOW); } void setMode(bool mode) { digitalWrite(MODE_PIN, mode ? HIGH : LOW); } void setup() { pinMode(SWITCH_PIN, INPUT_PULLUP); pinMode(MUTE_PIN, OUTPUT); pinMode(MODE_PIN, OUTPUT); forceMute(true); delay(100); currentMode = readMode(); setMode(currentMode); delay(POWER_ON_MUTE_MS); forceMute(false); } void loop() { bool newMode = readMode(); if (newMode != currentMode) { delay(DEBOUNCE_MS); newMode = readMode(); if (newMode != currentMode) { forceMute(true); delay(MUTE_BEFORE_SWITCH_MS); setMode(newMode); currentMode = newMode; delay(SETTLE_AFTER_SWITCH_MS); forceMute(false); } } }Some pics:
  10. ^ Agreed and nice fall off. Visiting my dad and hit a nearby car show last weekend. And by car show I mean a car. Rain threatened the event so only a 1974 Challenger 383 Four Barrel was left when I showed hours before the scheduled end. Quick tests of the used Hassy 55v f/2.5 I recently picked up. Much to learn.
  11. I'm looking forward to those as I'm slowly working on my own version just for me, i.e. fixing how they sound. :) I got these recently: https://poloyoaudio.store/products/hongshu-eh1 It is my third one of these as they design has been maturing over the years. I'm waiting on a replacement set as mine had some noise issues in one driver so I'll do a proper write up as they arrive but I do like them a lot. The earpads are crap but there is a lot of potential there.
  12. Here’s one of my secrets - I’ll take Coltrane and Bill Evans over Miles Davis any day. That’s probably little to do with the artists, but damn is this album great (the cover art is not)
  13. Standard geo, and probably thrown off by the extreme closeup. Yes, 58. Echo, 1st generation. I’ll take better pix when it gets here. TLDR - I had a friend who was looking for a gravel bike and mentioned that I had been thinking about moving the Canyon that I bought last fall. I had really bought that bike for the wheelset that was on it and so that my friend Tom would have something to ride for the century we do every year. Those two needs met, it wasn’t a bike I loved or really cared about so out it went a couple weeks ago. I had just missed the chance to buy a first-gen Allroad and had been looking at Allied’s offerings when I came across this Echo. Frame is from 2022, color is BMW’s Java Green Metallic, and it allegedly only has 1,000mi on it. I think I’m going to have Allied make a color matching stem for it and the wheelset will be getting upgraded from the Boyd aluminum hoops that there are there now. Should be a fun whip and will likely take over commenting duty.
  14. Dpa 4015gs -> mma-a Knoxville https://archive.org/details/jason-isbell-2026-07-17 https://archive.org/details/jason-isbell-2026-07-18 I’m jealous. I’ve wanted to see him but it hasn’t worked out for me yet.
  15. Great job Adam! You're definitely ready -- especially for a supported ride with breaks and refueling stops. Impressive progress!
  16. Unfortunately, the dusty haze kept me from capturing the full moon. It's normal here ☹️ I had planned to go to one of the highest points on the island on thursday to try and take some pictures of the Milky Way... I have confidence in my equipment but not in my abilities. Some photos with the RF 35mm F1.4L usm. I really like how this thing catches the light.
  17. AP NewsJudge questions difference between Hegseth's testosterone...Defense Secretary Pete Hegseth’s new initiative to test and treat troops for low testosterone is facing scrutiny from a federal judge.I kekked.
  18. yep exactly. on the back of the board as close to the output pins as possible.
  19. nothing with 60db of gain is going to be completely noise free. unless you want to move to a much colder climate. and even then maybe a couple of extra db of s/n. without a volume control in front of the input stage you have no idea how loud, loud is. that residual noise is undetectable when playing music. you can try say 10pf instead of 5pf. anything higher and the frequency response will change.
  20. Here's a fascinating (at least to me) series of lectures by one of my heroes - Richard Feynman. These are all about an hour long, and I was enjoying his engaging talks about diverse topics. For example, below. You get a flash at the beginning that I missed. But at the bottom it is Feynman Reborn, an AI Feynman, along with unmistakably his voice. There is a list of publications at the bottom (for example the Feynman Lectures on Physics). There is a series of these, and the only real hint that something is up is if you look at the background. I think that the authors of the AI Feynman left a really weird background to give a sense of the unreality of the superb AI Feynman.

  25. You'd better hurry, as Sunday is the last day, and this weekend is the Marathon which will make things interesting. I'll have to see if we can fit in a visit to see Boom and Bust before it's last day on August 2nd!
  26. Just to confirm, do you mean adding a .1 to 1 uF ceramic capacitor directly across the RKZE-1515 isolated supply output (+15V to -15V) that powers the CCS section?
  27. 1) damn, that's a tall headtube 2) 58? 3) I can't even tell which model that is, but you're the first Allied owner I know. Neat! 4) Where are the proper pix!?! And details!?!

    How about speaker model porn? A famous 1970s live rig from some jam band or other.
  29. the resistors are just there to make sure its stable with nothing plugged into it. change the input resistors to as low as possible compatible with what is going to drive it. 10k is probably what i would do.

  34. Here are a couple of posts in Audio Asylum from the late Mr. Charles Hansen (founder of Avalon speakers and later Ayre electronics) where he illustrated the history and inner working of HDCD. There are many more related posts you can find in Audio Asylum. I found them both educational and very interesting read. https://www.audioasylum.com/audio/digital/messages/18/184385.html https://db.audioasylum.com/mhtml/m.html?forum=digital&n=184436&highlight=HDCD+pacific+charles+hansen&search_url=%2Fcgi%2Fsearch.mpl%3Fsearchtext%3DHDCD%26b%3DAND%26topic%3D%26topics_only%3DN%26author%3Dcharles%2Bhansen%26date1%3D%26date2%3D%26slowmessage%3D%26sort%3Dscore%26sortOrder%3DDESC%26forum%3DALL
  35. I had a leftover crust, so tonight I decided to make spinach-bacon quiche so I'd have something good for breakfast.
  36. Finished this morning, devoured at work.
  37. Saturday was Pie Day so we had previously agreed to celebrate this week. So tonight I made but did not bake Taco Pie and also made the crust (and did bake) for a Chocolate Chess Pie.
