Daniel Marks<p>I finished assembling the TriacControl <a href="https://www.github.com/profdc9/TriacControl" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://www.</span><span class="">github.com/profdc9/TriacControl</span><span class="invisible"></span></a> speed controller, which phase controls a universal motor based on an analog or PWM signal. It is to control the router spindle speed for a 2.5D CNC machine using the PWM output of a CNC controller. It could also be used with the PWM of a microcontroller, as the input can be configured for 3.3V-24V. The control signal and motor are opto-isolated. <a href="https://mastodon.social/tags/diy" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>diy</span></a> <a href="https://mastodon.social/tags/electronics" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>electronics</span></a> <a href="https://mastodon.social/tags/openhardware" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>openhardware</span></a> <a href="https://mastodon.social/tags/hardware" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>hardware</span></a> <a href="https://mastodon.social/tags/opensourcehardware" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>opensourcehardware</span></a></p>
