the peristaltic pump

July 23rd, 2010 by g

We built a persitaltic pump to be capable of extracting the liquid from the tank without contaminating it.

In this case we use a stepper motor from an old printer. This motor executes 1770 steps to transport 10ml from one container to the other one, after that it does 1000 steps in the opposite direction to return the surplus of the sucked liquid that remains in the tube to the original container.

We improved the pump putting 8 skate bearings, 2 for each axis, to have more suction power, reducing the speed of the spin but increasing the power, looking for the optimum balance between these two variables.

The extraction is not always as precise as in the video, 2 ml up or down, but counting on this margin it works well for us.

a catch sight of spirulina

July 11th, 2010 by g

After 2 excursions to the pond of the Llobregat rivermouth, where we got some spirulina but we couldn’t isolate it after a couple of months working on it, Javi from Can Masdeu gave us some of this algae putting and end to our odissey.

The microscope is made out of a webcam with the lens inverted, monuted into the internal structure of a CD drive to control focus.

The machine is coming to life!

Peristaltic pump with animal draught

May 26th, 2010 by g

This short clip shows the peristaltic pump we’ve built with a silicone tube, 3 skate bearings and some wood and screws.

We are working already in the motorized version with a stepper motor, stay tuned.

getting closer

May 9th, 2010 by g

In this case we are using the lens of a digital compact camera, Pentax Optio s60, to get a higher magnification (=higher instability).

Not enough yet.
