Juice Injection pumps?

[WillyB]

The smallest TCS micro pump on that site flows at 150ml/min. That is a whopping 2 1/2 mil/second flow rate. The tubing looks like 1/8"?

How do you keep from flooding the atty?
I can only imagine that you have to both choke the tubing size on the outlet and reduce the input voltage to the pump. You still would have a few small window between "not enough" and "darn! 30 drops too many".

From the builder.

hold it 3 seconds get 3 drops of juice
