  • Mine is a ball python. They seem to prefer basking under the heat lamp after eating. Also they haven’t ever pooped in their water dish that I can remember, but I have had them horf up a partially digested rat in there before. That incident was made even more pleasant by the fact that I had their heat lamp positioned over the water dish at the time (to try and keep humidity up) and it happened while I was sleeping so I didn’t catch it for several hours. So I awoke to my entire house being filled with the miasma of a partially digested rat which had been stewing under a heat lamp for several hours. The smell was indescribable and beyond the imagination of any sane individual.



  • Oh yeah, basically the easiest way to do it would to pump water out of each basin, through a heat exchanger, and then back into the basin. That way you could have your whole temp control aparatus located outside of the terrarium. Plus that would also easily enable automatic water level management to keep the water levels identical. For your heat exchanger you could just use a CPU water block and a peltier device. You regulate the power going to the peltier device by monitoring a temp sensor in your water return pipe and just pulsing the peltier device on and off at different rates to control the heating or cooling rate. Plus with the peltier device you can just reverse the polarity to switch from heating to cooling to enable the shuffling of the basins. All of this would be controlled and charted in a csv file by a raspberry pi. Additionally you could connect a simple motion sensor so the pi could flag the times the snake was using one of the basins to make it easier to read the data.

    Rather than monitoring ambient temp or humidity you would probably be better off just keeping them tightly controlled and constant via other systems. That would further reduce variables for the initial test.




  • I have been thinking that all day. But to do it properly I need a bigger terrarium and some more supplies. You can’t have the dishes be different sizes or that’s an additional variable. But I also want to keep a big enough dish that they can soak in it. They never actually do because I keep the humidity high enough but they should still have the option.

    So I need to have a large terrarium with several identical water basins all in the same area. 3 basins would work (warm, room temp, and cool) but ideally I would have several set to various specific temps. Each basin should be able to be heated and cooled to reach a set water temp and which basin has which temp of water needs to be shuffled ocasionally to eliminate selection based on exact basin location or similar variables. That heating and cooling could easily be acheived with a peltier module and a temp sensor on each basin linked to a controller. You would also need a camera to view which basin the snake actually uses.

    Of course I already know what would happen. I would spend a couple hundred dollars setting all that up only to learn that my single braincell possessing snake would only ever use the closest basin.
