I hope he is wearing green wavelength filtering glasses. This laser is no play, it looks like at least 100mW. Even with the motors spinning, it isn’t really required much time under direct exposure to (slowly) damage your eyes.

I made one of these in the 1980′s back when a 2 mW HeNe laser pulled from service was over $100. We set it up at night pointed at the side of a warehouse during an art festival right over the Abita Turbodog keg. The spiro motors were battery powered and as the night wore on they got slower and slower until everyone was just kind of watching the dot whirl around. Good times.

assuming hes taking the right precautions, it looks pretty well balanced considering the spinning platform consists mostly of toothpick/steel wire and solder.

i wish people who did this stuff would use longer exposure/low sensitivity when taking video of it though, i’m sure the video is missing a lot of the patterning.

must..have..instructions…

also make a line-in for a headphone jack and up the voltage so you can use the variation in electrical frequency to drive one of the motors at varying speeds.
would be great for raves.

Awsome just photocopy my eyeballs a shot of expresso and im ready to party!

funny you mention that, gilliam, as when i first saw that video i was like, “alien portals bro”

I like this a lot, great project.

Pretty neat. Could this guy make a lightsaber for me next? But seriously, how can this not be bad for your eyes when watching firsthand….
