A Crummy Commercial

This was a weird video: source:  https://www.youtube.com/watch?v=nxUEOdC4VzU The weirdest thing to me is that data centers are rated by the power they use in gigawatts !  Here is a snip from a EE Times story about an OpenAI and AMD deal: . Lisa Su of AMD and Sam Altman of OpenAI A gigawatt is 1,000,000,000 watts or 1000 megawatts (nuclear power plants like Point Beach in Wisconsin are a pair of 625 megawatt plants). https://en.wikipedia.org/wiki/Point_Beach_Nuclear_Plant Maybe it's the QRPer in me, but why would anyone rate an AI Data Center by power rather than gigaflops or whatever the actual computing benchmarks are for AI, tokens ?  what are those ?  After viewing that video this Wisconsin data center seems sketchy to me: https://constructionreviewonline.com/openai-oracle-and-vantage-to-build-15b-lighthouse-data-center-campus-in-wisconsin/ It reminds me of this: https://wb9kzy.blogspot.com/2023/03/foxconn.html They knocked down some houses, did a lot of land grad...

I did a search using Duck Duck Go for:     pn5179 ham radio circuit schematic (I just happen to have a bunch of PN5179 transistors in the junkbox). And one of the links was: https://www.edaboard.com/threads/pn5179-equivalent-transistor-needed-for-construction.259327/  where I saw this: Ah, the little guy with the hammer !  That's from the QRP Popcorn blog.  So I tried looking at the QRP Popcorn blog and got this: Some of the QRP Popcorn pages are found almost completely intact on archive: https://web.archive.org/web/20241226034145/http://qrp-popcorn.blogspot.com/2022/10/some-analog-ic-gilbert-cell-mixer-notes.html  But I noticed that on some other pages, pictures and diagrams are missing, bummer ! BTW I also tried a search for: "Discrete BJT Transformerless Feedback Amp" (the title on that PN5179 circuit) and nothing - I was interested in seeing his comments on the circuit. Also, I didn't see any of his videos on Youtube either.  I'm hoping it's j...

I was looking for a rig schematic and happened to find this on the Archive site: https://archive.org/details/qrp-l?tab=collection Very cool, the digest archive ends around 2004.  The search is pretty decent.  It was a great list then although probably even better before I joined and after I left :)  Lots of technical content and activity reports - QRPers do stuff !
