Modular Hydroponic Tower Modifications

I modified the excellent original design by boundarycondition to suit my particular needs:
- strengthen the base for the Muskot pot. Here I took the 24cm ⅓ bracket designed by miqueltbjr and added additional rims to strengthen the lid.
- a control unit box to house the Arduino UNO, LCD display and PCBs for the other sensors (pH, TDS), the relais and other required electronics. The control unit box consists of three parts. The basic housing, the lid with holes for LCD and pushbuttons and on/off switch to control the unit and a cover to protect the lid from water spills. A thin transparent plastic sheet needs to glued into the cover.

- a bracket that fits over the pumphose and has customised holes for each of the four sensors (pH, TDS, water level, temperature). This ensure the sens
