It's been a long time since I updated this thread and lots of maintenance - after spring's down-turn and careful maintenance tank recovered to some degree but went down again during one of the heat waves - I usually keep my room AC at 78 and it's enough to keep the tank 78-80 degrees but this...
Raspberry alone is 40$ + SD + power supply - doesn't make too much sense when there are ESP8266/32 and/or Sonoff smart plugs controllable via any IOT API. IMHO linux is too much for those simple tasks like temp monitoring.
It's hard to make 3d print as strong as injection molding - PETG plastic might work if it's possible to get the old impeller off the shaft we can try to model it.
It'll get back once new sand is in place - been there, done that. Remove it completely - I was thinking of adding sand back after a year but without it looks much cleaner.
The downsides are that everything not glued to the glass will move around.
It sound strange but looks like we have to much of stylo already - I had to discard couple frags due to luck of space. We need frag swap ASAP! [emoji2957]

Hello,
I would like to share results of a project that was done more than a year ago but I think it's still cool. The idea and original design taken from thinginverse project, modified, remixed and finally re-designed from scratch.
The idea can be seen in this video -
I changed arduino to...
I have more 3d-printed tech - the more interesting is esp8266-based fish feeder - my first version is kinda rough but works for more than a year without problem. It connects to cloud and has cell phone UI based on blynk.io. I took the original from thingiverse and re-designed it for esp8266 and...
