== Obstacle ==
== Components ==
* plastic bottlesGlass bottle (recylcling should be better, pet is pretty bad for you)* * can be simply mate bottle, the geeky feel is a plus* Water pump:** the first solution is a hornbach water pump.* timer* Second solution would be a cooling system pump.* top * Fred: I have two water pump from coffee machine (230V)* Timer:** We can even go further and use an mbed, or the serial port of [foo|Internal_Server]. * Top and bottom reservoir of water * * No top reservoir should do it, we can add one after to normalize the water flow* Tubes:** some copper tubeswould add a nice touch to the whole thing** pvc tubes could be a simpler solution, but that wouldn't be that reliable under the heavy sun. list of components:<br>[[File:parts_list.pdf]]<br>Bottles cutting instructions:<br>[[File:bottle_cutting_templates.pdf]]
== Schedule ==
* 23 March: some pumping test with a coffee pump. Two main issue have occured : the pump is not powerfull enough it can only withstand a water column of 2 meters. The flow is also not important enough.
* 24 March : Second try with the coffee machine pump. The flow seems to be sufficient with a little tube. We can maybe use a double reservoir approach, one up and one down.
* 18 April : Basic pump testing with the coffee pump, it only need a nice box around it to secure the 220V connection. Apart from this, everything is working fine.
