s0 Traingirl Era<p>I wrote a quick blog post about my Soldering Fume Extractor v4 finally. </p><p>It's a relatively cheap (~AU$120), compact, effective and quiet fume extractor, that uses cheap off-the-shelf filters.</p><p>Anyone who's interested in making one, check it out. If there's more interest I'll see about building a v4.5 with stronger 7mm ply.</p><p><a href="https://blog.s0.is/blog/soldering-fume-extractor-v4" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">blog.s0.is/blog/soldering-fume</span><span class="invisible">-extractor-v4</span></a></p><p><a href="https://cathode.church/tags/tinkering" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>tinkering</span></a> <a href="https://cathode.church/tags/s0Projects" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>s0Projects</span></a></p>

s0 Traingirl Era<p>Gonna re-post my guide for anyone with a Mitsubishi Electric split-system Air con from the last 10ish years, on how to integrate it with Home Assistant/ESPHome for $20 with one extremely easy, reversible, safe hardware addition!<br>I've been running it without issue for 9 months now, and others have successfully followed my process.</p><p><a href="https://github.com/echavet/MitsubishiCN105ESPHome/discussions/183" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">github.com/echavet/MitsubishiC</span><span class="invisible">N105ESPHome/discussions/183</span></a></p><p>Original post here: <a href="https://cathode.church/@s0/113509209574322642" translate="no" rel="nofollow noopener" target="_blank"><span class="invisible">https://</span><span class="ellipsis">cathode.church/@s0/11350920957</span><span class="invisible">4322642</span></a></p><p>I've used the integration to do stuff like automatically turn off the aircon an hour after I go to sleep, and put an automation so if we leave the house, it'll turn the aircon off in case we forgot. I also built an automation to run it in fan only mode on low for 15 minutes after being on cooling, to evaporate the moisture inside that otherwise leaves to building up mould.</p><p><a href="https://cathode.church/tags/tinkering" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>tinkering</span></a> <a href="https://cathode.church/tags/homeAssistant" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>homeAssistant</span></a> <a href="https://cathode.church/tags/homeAutomation" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>homeAutomation</span></a> <a href="https://cathode.church/tags/ESPHome" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ESPHome</span></a></p>

s0 Traingirl Era<p>Had a dead Soundcraft Ui12 needing repair. Was browning out any PSU connected.</p><p>Ruled out the CPU board and DSP board, meaning it was the analogue board.</p><p>Sheesh, three factory bodges!

@Rp12Biker :verified:<p>The 3D printer is currently printing something really useful. Our food processor is missing the pusher for pressing potatoes/onions, etc. down.

AI6YR Ben<p>New data:</p><p>Definitely a Class 2 e-bike. There'a right hand throttle, which works to engage speed.</p><p>Then there is pedal assist. The pedal assist (appears) to be either on or off, though there's a switch on the left handle... not sure if that's "high" or "low" or what, but there's some kind of difference in how the engine kicks in when "pedaling"... ie how many strokes before it turns the motor on?</p><p>No speed control with the pedal assist... not sure if that's the expected behavior or not, it just turns the motor on when the disc passes the sensor at a particular time and then turns it off. </p><p>Except for the "ignition off" (missing key), there is no other button to turn off the pedal assist. So, you're either "pedal assist + throttle mode" or "off". One would think you might wish to occasionally turn assist on/off by pressing a button/switch. (this of course I can fix if I want by adding a switch inline with the "key" circuit.</p><p><a href="https://m.ai6yr.org/tags/bike" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>bike</span></a> <a href="https://m.ai6yr.org/tags/tinkering" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>tinkering</span></a> <a href="https://m.ai6yr.org/tags/bike" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>bike</span></a> <a href="https://m.ai6yr.org/tags/hacking" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>hacking</span></a></p>

hobbsc<p>it does seem to consume hella tokens but i did a quick test: on two blank dirs, i gave claude 3.5 the same prompt: "Write an OpenTofu configuration that will create a bucket in digital ocean spaces for storing OpenTofu state files."
