Rommudoh<p>One of the final modules for my <a href="https://social.tchncs.de/tags/StackSynth" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>StackSynth</span></a> project: the <a href="https://social.tchncs.de/tags/noise" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>noise</span></a> generator. It outputs white, blue, and pink noise and uses a #3904 and a <a href="https://social.tchncs.de/tags/TL074" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>TL074</span></a> with a lot of resistors and a couple of capacitors.<br>It is based on Moritz Klein's video: <a href="https://youtu.be/0yB_h_wFkh4" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://</span><span class="">youtu.be/0yB_h_wFkh4</span><span class="invisible"></span></a><br>I prototyped it on solderless <a href="https://social.tchncs.de/tags/breadboard" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>breadboard</span></a> and then designed the <a href="https://social.tchncs.de/tags/PCB" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>PCB</span></a> in <span class="h-card" translate="no"><a href="https://fosstodon.org/@kicad" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@<span>kicad</span></a></span> and let <span class="h-card" translate="no"><a href="https://aisler.social/@aislerhq" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@<span>aislerhq</span></a></span> manufacture them again. It turned out quite nice and sounds great.<br><a href="https://social.tchncs.de/tags/soldering" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>soldering</span></a> <a href="https://social.tchncs.de/tags/diysynth" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>diysynth</span></a> <a href="https://social.tchncs.de/tags/synthesizer" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>synthesizer</span></a> <a href="https://social.tchncs.de/tags/KiCad" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>KiCad</span></a> <a href="https://social.tchncs.de/tags/pcblayout" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>pcblayout</span></a> <a href="https://social.tchncs.de/tags/MoritzKlein" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>MoritzKlein</span></a></p>
