Subject: [alt-beam] tiny limit switches
content-transfer-encoding: quoted-printable
Evening all.
I've been using these really small limit switches on my HPV's for tactile s=
ensors, but I can't find a vendor. The ones that I've used have been glean=
ed from old CDROM drives. Anybody out there know where I can find these li=
ttle critters?
BTW, I have put four of the HPV's together and tried out different combinat=
ions of photodiodes, IR LEDs, and phototransistors for the eyes. In the da=
rk (I hooked up a 9V battery to them), the ones using the IRLEDs and the ph=
ototransistors exhibit negative phototropism. In the light, it's positive!=
Would that classify as emergant behavior?
