FYI the #ampache demo servers are moving house today.

Expect a few hours down time while they're physically moved over and I update the DNS to the new IP.

#ultrasonic and the Ampache #kodi demo sites use these demo's.

Another one for the #maker, #3dprinting, and maybe #science bubble:

What, if any, are the considerations when selecting a reasonably priced decent quality #ultrasonic cleaning bath?

Use case would be to clean and degrease/deoil small tools, glasses, watches, etc. Maybe a second unit some day to experiment with e.g. wood-chip infused milk; that second unit would remain food-safe.

I didn't get much farther than "probably stainless steel, and correct volume" -- and select that from eBay?

#Particulate Matter (PM) from Showers
