On Measuring
Using the arduino we can measure Analog Voltages using the 6 Inputs ADC. If the signals are to low, such as µV in the example of potentials in plants, we need to amplify the signal and make sure we do not have too much noise or other garbage in our signals. INA118 is a high end instrumental amplifier, with low noise. But maybe cheaper amp might do the trick aswell, such as the LM386
If we want to measure more inputs we can multiplex them. meaning we measure one input at the time using a chip (4051), which got 8 inputs which are then routed to one single input on the arduino. read more about using the 4051 multiplexer/demultiplexer

DIY Microscopy
To be able to observe the pipette we can build our own hacked digital microscopes, using cheap webcams, surveillance video cams or the PS3 eye. see more on the hackteria page.
