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.

a “12vdc massive motor from a savaged printer” costs at ona radio (barcelona) about 10 euros… brand new

i just purchased a water pump (350 l/h at 9vdc), 7,68 ex vat, and two sets of gears by cebek

fun guaranteed

In order to have a microscope to check the cultivated cells we’ve been experimenting inverting camera lenses to get some magnifications, here are the first results.

In this case we are using a Minolta reflex zoom lens at 28mm and infinite focus placed upside down in front of a Sony H20 compact camera with the optical zoom at x10. A support is essential to have a stable image.

A higher magnification and a built-in microscope is required though.

Seeing the results from the guys of Hackteria we got motivated to build something really similar. So once we get our webcam we’ll try out.

Coming soon new images!

since the schematics of this cheap phmeter are unknows we  decided to rip it apart

it all turn to be quite simple

the meter generates a voltage, but its too litte

so, op-amps are under study, with the great help of Alex Posada (Hangar)
