Location: Logan HS
Time: 4 hours
Goal: Fabricate the tanks and piping system for the Desalination Machine.
Students: Dom, Ben and Andy
Most students had the day off because the Junior were taking the ACT at Logan but Dom, Ben and Andy came in to work on the Desalination Machine.
We really wanted to focus on getting the PVC piping tanks and returns completed so we had and idea of how big this machine was going to be. We have to make a cart to haul it around and we needed to get dimensions so that could be build.
Andy and Ben worked on water sensors and a potentiometer for the main pump. The water sensor did not work as well as expected but the pump control did. We also had some thermistors (sense temperature) that we wanted to test out that were given to us, but we were unable to find a datasheet for them and they would not work on the existing program we have for sensing temp.
Ben also worked on our flow down matrix which is proving more difficult than expected. The hose we are using keeps kinking when we loop it to create layers so we are going to have to use some 90 degree connectors. We will continue to research and test solutions for this part.
Dom worked mainly on fabricating all the piping. The hardest part was getting the 4" pipe into the Fernco reducer. The Fernco is very solid rubber and it was unforgiving. We had to bevel the PVC pipe end and then use soapy water to get it into alignment. We did not glue anything in place yet as we just wanted to test fit everything.
Next work day will be spent on getting a flow down matrix created and make a platform to support our peltiers for heating and cooling.
