I want to build some automatically refilling flowers to use in a study of hawk moth foraging behaviour. The flowers will hold 2μl to 20μl of sucrose solution. The system must be capable of automatically recording data.
I need to be able to control:
1. Fill rate (μl /second)
2. Maximum fill volume (this may vary over time e.g. visit 1 moth gets = 20μl, visit 2 moth gets 6μl)
I need to record:
1. When moth drink (time)
2. How long it drinks for (time)
3. How much it drinks (volume)
These flowers must be:
1. Suitable for use in the laboratory
2. Fairly inexpensive (e.g. less than 100 pounds each)
Any ideas as to how I could achieve this?
