  1. it had been a while, I baked some bread.. Simple country loaf, About 24 hour fermentation, and my scoring was crap.

  4. After watching this: I thought I might try to make my latte look like something. I have never really cared in the past. After a two failed attempts during the week, I didn't have my foam right. Today I made a thing. Not great - but still drinkable... that's all...

  5. Another "welcome back" gift from a friend of mine. Starting to read it tonight. The Narrow Corridor: States, Societies, and the Fate of Liberty by Daron Acemoğlu and James Robinson.

  6. More Than A Feeling by Boston (1976) Because: There is a lot going on, and it was all done in the analog domain. impressive. So crank it up, and sing along like no one is watching / listening. You know you want to. Tariff Free!

  8. I put together a Nachos bar for the Saturday crew at work. To say it was successful would be understated for certain. It was decimated quickly. It was also a lot of fun.

  9. That looks great. I have tried and I've pretty much given up. Tastes great, but the art thing I'm screwing up consistently...LOL. HS

  11. I may be a hack, but I switched from using 4-gang pots to shunting stereo pots because I think they work better. A big part of the reason why I would build a balanced circuit is to benefit from its CMRR (and even order distortion cancellation by proxy). I measured the matching between gangs on a 20k RK27; it's better than the specified 20% tolerange, but it's not great. Here are some measurements at arbitrary rotations. Gang A Gang B Matching 51.4 51.6 0.4% 255.7 252.8 -1.1% 623 624 0.2% 1299 1300 0.1% 3042 3089 1.5% 4230 4368 3.2% 8470 9080 6.7% 14680 15420 4.8% 19100 19930 4.2% 19900 20380 2.4% The matching is directly proprotional to the CMRR. So I took a measurement of CMRR using the following circuit. The idea is that this simulates the balanced input of an amplifier and will tell us how balanced things actually are. Not very, it seems. Each trace is a different rotation angle on the pot, with the -115dB one being with the signal fully shunted. (There is some resitual resistance with the pot at 0.) -35dB of CMRR will significantly degrade an amp's performance. I repeated the measurements with a shunting pot configuration, using Yageo 1% 2k resistors and the same 20k pot. Although the AP input capacitance degrades CMRR at high frequencies, even the worst 1kHz measurement is about 12dB better than the best measurement with the series pot. The low frequency degradation is most likely caused by the AP's 1/f noise-- we're measuring microvolts at this point. If I wanted to further improve performance, I'd use resistors with better matching. The Vishay ORN arrays are available in 0.01% and would probably be my pick. LT5400 isn't bad either. https://www.mouser.ca/ProductDetail/71-ORNTA1001ZUF I don't know that this is necessarily relevant to the design in the first post-- looks like it doesn't use a pot at all-- but the circuit has its place.

  12. Two quick listens. Chicken Heads 50th Anniversary by Bobby Rush (2022) https://open.qobuz.com/album/p1a5wnkma1tzb Example: Just 4 versions of the same song: Bobby Rush, Buddy Guy, Gov't Mule, Christone "Kingfish" Ingram... I like Bobby's more raw blues, but the others are fun. And then more fun. A lot of things still hit: "Well, he may be a fool but he’s our fool" Good Old Boys by Randy Newman (1974) https://album.link/fw6p7j6rpszzd Example: Some really pretty tunes along with the hard hitters.

  14. Note to self -- Keep the induction cooktop away from the oven exhaust when I am baking at 500+ degrees... Mostly cosmetic, but may effect longevity... 🙃
