&lt;p&gt;It started with a spec sheet and a dumb question: &lt;em&gt;how tightly packed are the LEDs in the Steam Machine&amp;rsquo;s front light bar?&lt;/em&gt; It ended with a cloned kernel driver, a strings dump of the Steam client itself, and a from-scratch Linux kernel module driving a WLED replica. This is the story of everything in between.&lt;/p&gt;
&lt;h2 id="act-1-what-can-you-learn-from-one-product-photo"&gt;Act 1: What can you learn from one product photo?&lt;/h2&gt;
&lt;p&gt;The Steam Machine&amp;rsquo;s spec sheet gives you two numbers: &lt;strong&gt;17 individually addressable RGB LEDs&lt;/strong&gt;, and a case that&amp;rsquo;s &lt;strong&gt;156mm wide&lt;/strong&gt;. Divide one by the other and you get a density - about 109 LEDs per meter, roughly one LED every 9mm. Simple enough, if you&amp;rsquo;re willing to assume the strip runs edge-to-edge with zero bezel. It doesn&amp;rsquo;t, of course. Nothing does. So the real question became: how much margin is there, actually, and can we figure it out without a teardown?&lt;/p&gt;</description></item><item><title>Making WLED Lights React to Music — Without a Microphone</title><link>https://endemics.github.io/posts/wled-audioreactive/</link><pubDate>Tue, 02 Jun 2026 03:57:14 +0000</pubDate><guid>https://endemics.github.io/posts/wled-audioreactive/</guid><description>&lt;h2 id="how-i-wired-home-assistant-music-assistant-a-raspberry-pi-and-a-wled-esp32-s3-together-to-get-audio-reactive-lights-driven-entirely-from-the-music-stream--no-microphone-required"&gt;&lt;em&gt;How I wired Home Assistant, Music Assistant, a Raspberry Pi, and a WLED ESP32-S3 together to get audio-reactive lights driven entirely from the music stream — no microphone required.&lt;/em&gt;&lt;/h2&gt;

&lt;h2 id="the-goal"&gt;The Goal&lt;/h2&gt;
&lt;p&gt;I wanted my WLED-controlled lights to react to whatever was playing through my HiFi system — pulsing, flashing, and shifting colours in time with the music. The catch: I didn&amp;rsquo;t want a microphone picking up room noise, and I wanted it to work automatically whenever music played, without any manual intervention.&lt;/p&gt;</description></item></channel></rss>
