root42<p>Question to all the <a href="https://chaos.social/tags/ee" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>ee</span></a> or <a href="https://chaos.social/tags/electronics" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>electronics</span></a> experts here: I have two TI chips here. the one in the background is from 1985 and has shiny legs. The one in the foreground I bought in the last 5 years new from Mouser. It came with those tarnished legs already from the factory. Why are the legs so tarnished? What coating does TI use that makes it so black looking. I understand that back in the 70s supposedly TI used a silver coating that turned black over the decades, but this is something different...?</p>

amen zwa, esq.<p>When I was an undergrad <a href="https://mathstodon.xyz/tags/EE" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>EE</span></a>, I used the then-current "Advanced <a href="https://mathstodon.xyz/tags/Engineering" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Engineering</span></a> <a href="https://mathstodon.xyz/tags/Mathematics" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Mathematics</span></a>", <a href="https://mathstodon.xyz/tags/Kreyszig" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Kreyszig</span></a> (4ed, 1979).</p><p>It's a superb book for engineers. Over the decades, I've always recommended it to young engineering students. But for the past 10 or 15 years, my new favourite textbook on the subject is "Mathematical Methods for Physics and Engineering: A Comprehensive Guide", <a href="https://mathstodon.xyz/tags/Riley" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Riley</span></a> (3ed, 2006).</p><p>The first edition of this book came out in 1997, which was long after my school days. These days, I always advise young engineering students to read Riley, even if their uni uses a different textbook.</p><p>Riley 3ed—<a href="https://www.amazon.com/Mathematical-Methods-Physics-Engineering-Comprehensive/dp/0521679710" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://www.</span><span class="ellipsis">amazon.com/Mathematical-Method</span><span class="invisible">s-Physics-Engineering-Comprehensive/dp/0521679710</span></a></p><p>Kreyszig 4ed—<a href="https://www.amazon.com/Kreyszig-Advanced-Engineering-Mathematics-4ed/dp/0471042714" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://www.</span><span class="ellipsis">amazon.com/Kreyszig-Advanced-E</span><span class="invisible">ngineering-Mathematics-4ed/dp/0471042714</span></a></p>
Alex@rtnVFRmedia Suffolk UK<p>I was in a gastropub for a works Christmas meal on Friday. In spite of being in 5G LTE area, <a href="https://social.tchncs.de/tags/mobile" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>mobile</span></a> <a href="https://social.tchncs.de/tags/Internet" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Internet</span></a> was heavily lagged and barely anything worked. Network Cell info showed device hunting between 800 MHz, 1800 MHz and 2100 MHz. I didn't have my RF Explorer with me (or I would have been highly tempted to scan the airwaves!) but either <a href="https://social.tchncs.de/tags/EE" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>EE</span></a> / <a href="https://social.tchncs.de/tags/BT" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>BT</span></a> cannot handle the traffic in that area, or Christmas tree lights in the pub are chucking out wideband RF <a href="https://social.tchncs.de/tags/interference" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>interference</span></a> (both are possible!) >></p>
amen zwa, esq.<p>Despite the several decades that had passed, I still recall vividly the very first time I, a first-semester <a href="https://mathstodon.xyz/tags/EE" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>EE</span></a> undergrad, wandered into my college’s <a href="https://mathstodon.xyz/tags/engineering" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>engineering</span></a> library, strolled through the aisles, absentmindedly picked up a Bell Labs technical journal on telecommunications, thumbed through the first few pages, then muttered to myself, “Huh?”</p><p>That day, I learned a life lesson of immense value: how not to use an engineering library.</p>
