#mastoadmin This happened to me with a live server, and I've verified it experimentally, and so I pass it on to you:
If you're upgrading to Mastodon 4.3.x, it no longer supports Postgres 9, and it's tempting to export your PSQL 9 database and import it directly into a more modern version like 12 or 16; this is supposed to auto-convert it to the new format.
Please don't. Step upward by one version at a time. The direct upgrade trashes Mastodon's performance somehow.
mitxela has built an #LED matrix earring from 52 0201(!) LEDs (i.e. 0.65 × 0.35 mm footprint) on a 9 mm diameter circular PCB. Or rather, two PCBs soldered back-to-back because this density of components basically requires a four-layer PCB with blind and/or buried vias, which would've been very expensive. The video also features a "very cheap" (3600 USD) pick & place machine. I expect these to show up in makerspaces soon.
