The internet‘s ruthless efficiency killed little shops run by old men where they would find you a specific screw, bolt etc from their dusty boxes out the back. Now the internet has gone to shit, you google that specific item and get shown a big pile of random loose screws. Bring back old man shops.

Stainless steel knurled thumb screws, high type. No use to me because I want M4 knurled brass thumb nuts, high type.

It bothers me that Bach's Toccata and Fugue in D minor is invariably associated with horror/occult. I grew up as the child of an organ builder and in my early experience that was just another piece by good ol' Bach and it brings happy memories. Sad that it's tainted as weird.

I'm saddened to report that my friend and colleague Paul Schreiber passed away this morning. He was a consummate engineer with deep roots in music and technology and worked on the TRS-80, the Realistic Concert-Mate MG-1 synth, the MOTM modular system and many Eurorack modules. He will be missed.

Yesterday we had a wet weather system (first one in months) come thru the Phoenix area. It dumped some snow in the high country, including the Four Peaks area northeast of town. We took a drive up that way this afternoon and caught this panorama.

A panorama photograph of a desert scene. A gnarly dead tree on the left side, snow-capped mountains on the horizon and dry, grassy scrub in the near area. Saguaro cactus in the near distance and blue sky with little fluffy clouds above.

Rewatched "The Lost Boys" tonight. Found myself identifying more with Barnard Hughes' Grandpa character this time than I would have expected the first time I saw it. Gotta say though - that's some weapons-grade 80s nostalgia.

Somewhere in my neighborhood a dog is barking incessantly. The reverb on that sound is amazing - far away with a really long tail. That'd be a good audio effect.

The deserts of central Arizona are being overrun by an invasive species - Globe Chamomile aka "Stinknet" was accidentally introduced from southern Africa. There's no known way to control it aside from herbicides that cause collateral damage. I don't think we'll win this one.

Cute yellow flowers that look like tiny balls on the end of long stalks amid a haze of greenery with a blue sky in the background.

NBC showing the 1st Harry Potter movie tonight. Lotsa pharma ads. I guess they're admitting that it's not a movie for kids now - it's for old folks who remember when they were kids.

Assembled PCBs back from JLCPCB - they did the SMT parts and I added the rest (pots, jacks, connectors, etc). It's a prototype Eurorack audio generator based on a CH32V003 MCU driving a PT8211 stereo DAC. Three CV inputs, one gate input and two audio outputs. A button and RGB LED for mode control.
