https://www.allaboutcircuits.com/news/toshiba-debuts-thermoflagger-as-temperature-sensor-ic-alte rnative/ This seems awfully silly to me. At least it's cheap, about 13 cents. Maybe it's useful for something else.

The circuit has to operate in both differential input and single ended input modes. When in single ended input mode, there's no way to ground one input, so it will float. In this circuit, the two inputs are tied through C9. So I can't see how this circuit would allow single ended operation. If, however, C9 is split in two, as a pair of 1 uF capacitors to ground, that would se

UPVC Jakarta Pintu kusen jendela UPVC adalah salah satu jenis pintu yang populer digunakan dalam bangunan rumah tinggal. UPVC sendiri adalah kepanjangan dari unplasticized polyvinyl chloride, yang merupakan bahan yang tahan lama dan tidak mudah rusak. Pintu kusen UPVC memiliki banyak keunggulan dibandingkan dengan pintu dari bahan lain seperti kayu atau aluminium. Pertama, pintu kus

https://www.bbc.com/news/uk-wales-65615890 I was paying $5 to $7 a dozen for medium eggs just four weeks ago. Now I can by them for $2.25 here in Puerto Rico. WTF? How can prices fluctuate so wildly in such a short time? Even semiconductors took some time to elevate prices. It would seem semiconductors are coming back to normalcy though. All the parts I've used in my designs that ...

I don't know what the th is in the expression f/fth. "The rate of coalescence in AC field is characterized by a sharp threshold frequency. At f/fth there is no coalescence, whereas at f/fth coalescence depends on magnitude as well as frequency of the applied field." Thanks, Mikek P.S. Even if I understand the term, I'm not sure the sentence mak...

Article: Given that the thermosphere extends out to several hundred kilometers, that 342 meters might not seem like a lot. However, a paper published in September by physicist Ingrid Cnossen of the British Antarctic Survey in the UK showed that thermospheric cooling could result in a 33 percent reduction in atmospheric drag by 2070. Atmospheric drag is what helps satellites and r
