There is pretty much two options for creating the payload:
- Buying a pre-made styrofoam insulated box.
- Making your own custom made design from polystyrene sheeting.
After a bit of research, we decided on making our own. This would allow us to create precisely the size we needed, something that our components would fit tidily into and into which we could also include internal compartments. Furthermore, the available pre-made sizes seemed to be rather heavy so we figured there was a weight saving to be made with a DIY box.
We purchased several sheets of yellow Styrofoam. We only needed two – but better safe than sorry. We were advised that the yellow styrofoam made less mess when cut than the white. We also purchased glue specially designed for styrofoam. Regarding cutting the polystyrene, we looked into the benefits of a hot wire cutter but since we were only cutting straight lines we decided to take our chances with household tools.
Finally we have got a cheap, lightweight payload where you can enclose the equipment. It has good thermal insulation and is sturdy enough to sustain a fall without damaging anything.
