Re: The Corona Virus Hoax of 2020

I find it hard to believe that he would publicly suggest killing old people. Those ted talks must be pretty edgy. Ted Turner chiseled "The Good Club's" goals in stone at the Georgia Guidestones. How much more obvious do they have to be before you see this JR? I was not familiar with the "Guidestone...

Re: The Corona Virus Hoax of 2020

It does raise the question of why invest in trying to protect those with the least years remaining but this is a political decision not economic. Bill Gates summed it up in his Ted Talk. Old people cost too much to take care of. Soft-killing them with vaccine is low-cost and he can make money doing...

Re: The Corona Virus Hoax of 2020

55 deaths coincident with 12M jabs may be statistically significant or not... This first cohort receiving vaccines are the oldest, and weakest among us, so some of them would have expired anyhow... the foaming mouth was a nice detail to make this seem scary. :lol: It does raise the question of why i...

Re: The TL071, TL072 and TL074 "H" Next Generation Enhanced Versions

I checked and digikey has inventory on both H and non-H parts including TL07x from non-TI vendors. Can you send me the link to the TI "H" parts? I couldn't find them on Digi-Key either. https://www.digikey.com/en/products/detail/texas-instruments/TL074HIDR/13563033 smd not TH parts... but they show...

Re: The TL071, TL072 and TL074 "H" Next Generation Enhanced Versions

It would be nice to see an updated schematic if they changed the insides. It is not surprising that they may want to call a new part by the old part number to keep all the design-in volume... (like the sundry newer 2n3055s that are not the same as the original). I checked and digikey has inventory o...

Re: The TL071, TL072 and TL074 "H" Enhanced Next Generation Versions

My bad... I didn't catch that but saw a written warning probably referring to the old non-H versions. Something like avoiding 1V from minus rail. I did find another "H" spec that looks like 1/2V below - rail is OK. :oops: JR PS: I don't see anything obvious different about the internal schematic but...

Re: The TL071, TL072 and TL074 "H" Next Generation Enhanced Versions

Looks like process upgrades/improvements.

From notes, they still haven't fixed the polarity reverse when inputs get close to - rail, unless they forgot to mention that.

Re: beverly hillbilly storm windows and cybernetic heat control

I just got my latest electrical bill nudge this time saying I used 4% less electricity than my efficient neighbors. This doesn't reflect my recent changes just finished. My new strategy is to shut off my 600W of auxiliary heaters and rely on just the single 250W baseboard heater and blower, to bring...

Re: Entropy

Going back to the old trap post... I often bleach my traps and also run a lot of boiling hot water through them. Then lots of hot water-heated water. It takes 2-3 feet/sec flow rate for a pipe to self-clean. Bleach isn't so great for metal traps but mine are all PVC now. connecting another dot or t...

Re: Entropy

Today's entropy episode involves my smart battery charger... today after returning from my once a week shopping trip that is inadequate to keep my car battery topped off, I connected my smart charger (plugs into the cigarette lighter).With no charging... I first checked the obvious suspects and char...
