cybervegan<p><a href="https://autistics.life/tags/JournalEverything" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>JournalEverything</span></a> DIY bike shed alarm update: I've been chewing this over for a few days now. I didn't post about it at the time, because I was still processing it. </p><p>I was busy hooking the updated ESP32-based external alarm panel electronics up on Saturday night, in fact I was nearly done, and as I was working I noticed a "hot electronics" smell. No <a href="https://autistics.life/tags/MagicSmoke" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>MagicSmoke</span></a> but a definite "hot" smell. Using my built-in temperature sensor (aka index finger) I traced this to the actual S2-mini ESP32 board. And it was hot enough to make me recoil. <a href="https://autistics.life/tags/BadNews" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>BadNews</span></a> .</p><p>I disconnected the power - both the battery backup and the DC feed and bailed. It was dark and I was well overstimulated from trying to get everything wired together properly in the cramped space of the enclosure box. </p><p>So I've been mulling this over "on the backburner" (i.e. subconsciously) ever since. I hadn't reached any conclusions yet, so I let it sit there.</p><p>This morning, I have some ideas/theories. Will be investigating further:</p><p>1. The piezo sounder could be drawing too much current. It was sounding constantly from the time I hooked up the backup battery.</p><p>2. The tone() call I'm using to drive could be too CPU intensive.</p><p>3. The <a href="https://autistics.life/tags/ESPNOW" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>ESPNOW</span></a> radio comms is somehow causing the heat - perhaps winding the output power up really high because it was getting no response from its peer, which was switched off at the time. I don't know how much, if any, handshaking ESPNOW does.</p><p>4. Something else electronic is drawing too much current through the onboard voltage regulator or similar.</p><p><a href="https://autistics.life/tags/WeWillSee" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>WeWillSee</span></a></p>
