My initial idea was to visualize cockroach’s movement by creating tiny robot
that moves by itself to random places.
I’m not sure I can call it robot, but basically it is like a tiny robot that runs by
3v battery and motor to generate random movement. Then it draws with
mechanical pencil lead on the surface as it moves, and creates abstract drawing.
It wasn’t easy to come up with an idea to put an battery on to it since
motor is too small, and it only has small surface.
first prototype.
I ordered these solar cells from Sparkfun.com. This little thing can generate
up to 4V when it exposed to the sun, but unfortunately it has tooooooo! low
current. Thus, I can’t not make this to power up anything, not even single LED.
So, I have to go plan B, which I don’t have… lol, or try to connect series of them,
and hope it to create enough current to run my tiny motor.
Update:
I had an experimental with Elio in the sensor lab to find way to store little current
that solar cell generating.
Well, it turnes out that I can use this super capacitor to discharge current only
when it is charged manually from 3v source, while solar cell generates little
current. However, current that solar cell generating is too small that it cannot
charge the capacitor when all the current of capacitor is fully discharged.
Thus, I will not use this solar cells for this project, but it is worth it to explore
and experiment with it.
