<p>This feels like it could be a rich source of graduate student projects for years to come: <a href="https://turso.tech/blog/introducing-limbo-a-complete-rewrite-of-sqlite-in-rust" target="_blank" rel="nofollow noopener" translate="no"><span class="invisible">https://</span><span class="ellipsis">turso.tech/blog/introducing-li</span><span class="invisible">mbo-a-complete-rewrite-of-sqlite-in-rust</span></a></p>

Like, my trigger crossbar started in September (?) of 2023. Sure I spent $1K ish on the board but that&#39;s $66 a month so far and the firmware isn&#39;t even done yet.</p>

<p><span class="h-card" translate="no"><a href="https://chaos.social/@gsuberland" class="u-url mention">@<span>gsuberland</span></a></span> Fair enough.</p><p>I normally work on designs where I spend a month or more of spare time on schematic and layout, put several hundred dollars at *least* of parts on it, then months on firmware.</p><p>The board needs to just work, so I&#39;m going to do everything I possibly can to tip the odds in my favor and minimize the chance of needing a respin because of something stupid.</p>

<p><span class="h-card" translate="no"><a href="https://ioc.exchange/@azonenberg" class="u-url mention">@<span>azonenberg</span></a></span> I personally don&#39;t mind working around these issues because it&#39;s soooooo cheap. More than enough to be the difference between me doing a design and not doing it.</p>

<p><span class="h-card" translate="no"><a href="https://chaos.social/@gsuberland" class="u-url mention">@<span>gsuberland</span></a></span> This kind of thing is why I haven&#39;t been a fan of JLC and similar places except for cheap &quot;I don&#39;t care about quality or performance&quot; stuff.</p><p>I&#39;d rather give the fab a full material spec and stackup and have them either use it or tell me they can&#39;t do it.</p>

<p>I&#39;ve noted this flaw in the question and asked them to add a feature where it warns you about this issue.</p><p>They won&#39;t do Tg135-140 for 8L, only Tg155, so it&#39;s correct there.</p><p>For 10L and up they use S1000-2M instead, which they refer to as Tg170 (it&#39;s actually Tg180 according to the datasheet, so I&#39;ve posted another question about that discrepancy), and their impedance calculations correctly assume that material, so the issue is avoided here. It&#39;s only the 4L and 6L boards that are affected.</p>
