Hello,
I am looking for a simple device that dispenses liquids that is
computer controlled via a USB or serial port. Nothing fancy but I just
need to control the amount of a liquid that get dispensed in a bottle.
For example when you go to Home Depot and get a certain color paint,
they put the can of white paint underneath a nozzle, enter in the
color on the computer and the computer dispenses a few different
colors to create that paint. I am looking for that kind of dispenser.
I would write the software. Any ideas? Sorry is this is the wrong
group to post this in but I am trying to figure out where to start.
Thanks

One possibility is to use a peristaltic pump or a syrings pump driven by a
stepper motor. |

Companies such as Zymark or Gilson might have some equipment such as
syringe pumps that can be controlled by computer. Check that they can
tell you the commands, or alternatively supply a manual that can
first! You must also ensure that the pumps are using something you can
access using whatever language you are using (RS232 I'd guess)

I use an old Hamilton Bonaduz Microlab MT Diluter/Dispenser
syringe pump. It is controlled by simple commands over the RS232
port. The three-way valve can be set to either Prime or Dispense.
The plunger can be moved up or down the length of the syringe
in 1000 tiny steps.
Hope this helps,

You will need different pumps and controls depending on the volume you
are dispensing. EFD makes air-actuated systems for dispensing small
amounts repeatedly. www.efd-inc.com

Yup.
EFD just came out with this:

Search under infusion pumps to find more.
