DIY: auto AC for your pet fish
The sweat came out in a fine dew on my forehead when I left a room with AC and get outdoor yesterday. It just came up to my mind that my pet fish may need their own auto AC since I would go for a trip some day. So I DIY an AC through Waterproof DS18B20 Digital Temperature Sensor from DFrobot. It suits every rectangular fishbowl and costs little power.
Here is a tutorial for anybody new here to build such a device from 0 to 1.
