<p><span class="h-card" translate="no"><a href="https://mastodon.social/@whitequark" class="u-url mention">@<span>whitequark</span></a></span> the pin 1 mark is a pit not a bump</p>

<p><span class="h-card" translate="no"><a href="https://ioc.exchange/@azonenberg" class="u-url mention">@<span>azonenberg</span></a></span> if you look carefully you&#39;ll see two raised(?) bumps which make grinding unlikely</p>

<p><span class="h-card" translate="no"><a href="https://mastodon.social/@whitequark" class="u-url mention">@<span>whitequark</span></a></span> How many pins? This looks like a Xilinx package, FFG676 for Kintex-7 isn&#39;t too different.</p><p>I would expect there to still be laser markings on it though.</p>

<p>Hello Mastodon! I&#39;m a power engineer who is trying out solo game development and on the way to release Power Network Tycoon - a game where you build and manage your own electrical grid with real physics simulation.</p><p>If you&#39;ve ever wondered how power systems actually work (or why they fail), this might be your jam. I built it to be technically accurate while still being fun. To say it&#39;s been a challenge is an understatement...</p><p><a href="https://mastodon.social/tags/GameDev" class="mention hashtag" rel="tag">#<span>GameDev</span></a> <a href="https://mastodon.social/tags/IndieGame" class="mention hashtag" rel="tag">#<span>IndieGame</span></a> <a href="https://mastodon.social/tags/Simulation" class="mention hashtag" rel="tag">#<span>Simulation</span></a> <a href="https://mastodon.social/tags/Gaming" class="mention hashtag" rel="tag">#<span>Gaming</span></a> <a href="https://mastodon.social/tags/Energy" class="mention hashtag" rel="tag">#<span>Energy</span></a></p>
