botvolutionQuestion for the more industrial electronics/electrical peoples here:I've got a little build on the stocks which requires quite a few wire-to-pcb connections. The BOM uses TE MTA-156, but those really require a special (absurdly expensive) tool to attach the wires to the female connector.I'll sodder the wires direct to the PCBs if I have to, but I wondered what other neat, pluggy, inexpensive solutions there might be?<a href="https://mastodon.sdf.org/tags/diyelectronics" class="mention hashtag" rel="nofollow noopener" target="_blank">#diyelectronics</a> <a href="https://mastodon.sdf.org/tags/electronicsdiy" class="mention hashtag" rel="nofollow noopener" target="_blank">#electronicsdiy</a>

Fredrik JanssonVacuum tube radio progress: got decent reception of several medium wave AM stations: BBC radio 5, Radio Caroline and a Dutch one. I learned to stay away from switching power supplies, all I tried were so noisy I couldn't hear anything else. With a linear supply the sound is pleasant, but could still be a bit louder. <a href="https://mastodon.online/tags/radio" class="mention hashtag" rel="nofollow noopener" target="_blank">#radio</a> <a href="https://mastodon.online/tags/diyelectronics" class="mention hashtag" rel="nofollow noopener" target="_blank">#diyelectronics</a> <a href="https://mastodon.online/tags/vacuumtube" class="mention hashtag" rel="nofollow noopener" target="_blank">#vacuumtube</a>
