I mean static buildup in the box of drawers, from the drawers rubbing against the frame.</p><p>Thank you!</p>
niconiconi<p>Wrote more documentation. GUI software tutorials are tedious to write. It's just an endless repetition of "where to click things."

Memecosystem Services<p>First finished (??!) print!! Paper made from linen and ryegrass with some sphagnum inclusions. Cyanotype print is made from historical pamphlets, maps and images concerning postwar Irish agriculture. The print was then toned by soaking in water from a bog in Lixnaw in North Kerry. Finally, a clover is embroidered along the line of a gas pipeline map on the print with conductive thread, allowing the print to be a touch sensor for electronics. <a href="https://social.coop/tags/papermaking" class="mention hashtag" rel="tag">#<span>papermaking</span></a> <a href="https://social.coop/tags/cyanotype" class="mention hashtag" rel="tag">#<span>cyanotype</span></a> <a href="https://social.coop/tags/electronics" class="mention hashtag" rel="tag">#<span>electronics</span></a> <a href="https://social.coop/tags/EnvHist" class="mention hashtag" rel="tag">#<span>EnvHist</span></a></p>

✨ justada :polish_cow:<p>I received an old car radio some time ago and decided to scrape components from it. One of the chips was a TEA6330T sound fader, that miraculously has a not classified datasheet ( <a href="https://pdf1.alldatasheet.com/datasheet-pdf/view/19741/PHILIPS/TEA6330T.html" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">pdf1.alldatasheet.com/datashee</span><span class="invisible">t-pdf/view/19741/PHILIPS/TEA6330T.html</span></a> ) so naturally i decided to bring it back to life with a custom Arduino library! <br>You can view the lib on my github here: <a href="https://github.com/adreline/TEA6330T" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://</span><span class="">github.com/adreline/TEA6330T</span><span class="invisible"></span></a><br>The library includes functions for every option the documentation mentions. I tested it without actual speakers but the chip responded correctly to all the commands. Sound test remains on my todo list.</p><p><a href="https://eldritch.cafe/tags/arduino" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>arduino</span></a> <a href="https://eldritch.cafe/tags/electronics" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>electronics</span></a> <a href="https://eldritch.cafe/tags/diy" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>diy</span></a> <a href="https://eldritch.cafe/tags/tech" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>tech</span></a> <a href="https://eldritch.cafe/tags/sustainability" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>sustainability</span></a> <a href="https://eldritch.cafe/tags/upcycling" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>upcycling</span></a> <a href="https://eldritch.cafe/tags/salvage" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>salvage</span></a></p>
Dave<p>Assumed this was a spade terminal to earth and broke it off the power transformer. I think this is a ring lug thermistor? I get 120ohm across the two wires at room temp. Any idea what the nominal value might be? The markings E2 75, maybe 7.5kOhm? </p><p>Amp goes into protection mode without it so I've put a 2kOhm resistor in its place which lets it power on but the speakers are very quiet now. Could it be winding back the power in response to temperature? <a href="https://mastodon.me.uk/tags/hifi" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>hifi</span></a> <a href="https://mastodon.me.uk/tags/electronics" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>electronics</span></a></p>

niconiconi<p>Wrote more documentation. "The classic 1990s Tcl/Tk (Tkinter) GUI may look old-fashioned, but it works, and will keep working until the end of time."

I think the photo I'm working from for this practice kit is wrong. I read that the stripe on an electrolytic capacitor points to negative, but the completed kit photo shows the stripes pointing to the positive indication on the board. The two latter snaps are my WIP board. Who's right?</p>

The one in the foreground I bought in the last 5 years new from Mouser. It came with those tarnished legs already from the factory. Why are the legs so tarnished? What coating does TI use that makes it so black looking. I understand that back in the 70s supposedly TI used a silver coating that turned black over the decades, but this is something different...?</p>
