We had national holiday last friday and I had very little time to work on this project (I wish I had it done by then).

Shape of the pump, it's connectors and extra battery pack made fitting the components inside the case a (small) challenge. In previous version of this project both water pump and it's batteries were simply glued to the back of the device.

I made short 2-minute video describing the project and showing how it works (in garage). I will post it in the description section. I had to skip a lot of footage to meet ~2 min requirement, if I won't receive temperature probes this week I'll upload it, as it is always better than nothing.

Next step: tripod and bottle holder
