assignment
what will it do?
It is aimed to make Biosphere2( that multiple species living in the closed environment live with ecological balance) that can be placed on the desktop. To keep it long term , it will be able to manage temperature and light. And it has various sensors, so we will be able to obtain information(biosphere recipe)to make longer .
who's done what beforehand?
- Biosphere2
- eco sphere by NASA
- device like...Aquapioneers by Teyssie Guillaume

what tasks need to be completed?
what questions need to be answered?
- How do I milling branch parts?
- What do you do with the power supply part of the circuit? The heater uses a relay to move 100 V, but can it be shared?
- What to do with water moving? Is it a pump or fan? Can it be made smaller?
- I want to let the ball out. How do I make the connection part?
- How do I waterproof the sensor?
what is the schedule?
I do not like schedule.I use only task list.
how will it be evaluated?
Can ecological balance be maintained for more than half a year or not
