It's impressive. Art is subjective. This piece, especially. https://sfstandard.com/2025/04/20/naked-lady-sculpture-sf/ https://sfstandard.com/2025/04/20/naked-lady-sculpture-sf/

Does the new sculpture look better in person?

Hello Friends, a nice family shot with no load, no current limitation. Have to figure out why the bias doesn't kick in at 580V, otherwise quite happy. Edit, discovered it's the dmm impedance, bias is just right 👍

That was fast! Thanks a lot. -
Find it. I will share the info here anyway if you are curious. The switching freq range is between 900 to 2400(kHz). Lower than the LMQ, but shouldn't have any problems. https://www.ti.com/product/TPS62913

I don't what chip it is. Marking might be???? Very hard to see. 26QH 288 A3HL Including in curcuit is also dual comparator 2093B and .05R sense resistor. Good luck and looking forward a report. -
It's a great idea. I’ll likely move forward with the current plan for now since I’ve already ordered the PCB prototypes, but I definitely want to explore how that auto-detect function works. My guess is that it detects the difference in cold filament resistance between 2A3 and 300B tubes, but I’m not exactly sure how it’s implemented in detail. I’ll need to dig into that more. Also, from the image you shared, you reminded me that I should probably add a few small ceramic caps for filtering (like C9, C8, C7 on the right side of U1). Thanks for the heads-up.😅 The test PCBs should arrive this weekend. If I’m able to populate and test them successfully, I’ll report back with results. BTW, do you know what kind of DC-DC chip on the picture? Too blurry for me to read.

Took a Boat To The City Saw some controversial art. SF prices? Walked to a tech conference, where the zeitgeist is not just AI, but agentic AI. With phat/sick beats. And the expected A/V kit. Had a tech demo from a CEO, as one does. No need to be alarmed, citizen. Your timer starts now ... The conference ended with a nerd get together ( Code Block Party) Then some San Franciso Street Life And a First Thursday Gathering with one of many Waymos. Then back past the art, In time to catch the Last Ferry back a busy, but enjoyable day

Corporate Marketing Budget Depletion by eating in San Francisco today. There was quite the selection. But choose wisely! I think I did. But a reminder to always read the small print to avoid failure of expectations. A neighbor at my table thought they were getting a Bacon Cheeseburger, But instead got a "Bacon" Cheeseburger. Plant based Bacon sounds like an oxymoron, and was described as "an abomination". Avoid. However, later that day there were cheese truffle fries. Not bad. Where's the duck fat, though?

Nice idea. If you can implement an auto detect function as well – like Elekit has done with TU-8900. Power module… filament supply in black square, and the tiny - 2mm x 2mm - step-down converter. -

So some Chinese folks were caught smuggling in a grain fungus. They are either overzealous researchers or part of a plot to attack Crops. Either way, not good. Too many bad things are caused by Irresponsible actions like this. Let's hope this isn't an evil plot. If it is, they'll try again.

Visiting around Paris. Paris, Tennessee that is. It's a great place to see nature. But today's weather is a bust. Great retirement location.

Where did you found the schematic? We canot find anywhere in the thread. maybe you can share the link to the classified? sometimes one can find new sellers searching the pictures. I am deeply sorry I meant the to ask if the center board unnecessary?? is the same true for the board mounted on the sides? if unneccessary why are they there??
