That looks extremely unsafe.

We're on Hacker News - a site focused on startup and entrepreneurship. Risky, dangerous, and unsafe are all buzzwords that we flock to.

Yes but you can go from seeing to blind in under a second with these lasers - and anyone else unfortunate enough to be hit with one of these.

It's not only unsafe but possibly criminally negligent to operate this as is shown on that page.

All I can really say about this is that I want one. Now.

According to author, it costed him about 1000 zł - it's about 300 USD. Laser diodes are taken from DVD burners and Blu-ray readers, he also used current stabilizers taken from HP printer, but the most expensive parts, being half the cost, were galvos, used for moving the ray.

He said that it's certainly unsafe, and not only because of potential eye damage -- combined static ray is capable of burning through the cardboard and creating skin burns.

So if I offer $600 he might make me one? :)

Even given the safety issues, it's still very impressive.

You can just hire commercial ones. Multicolour may be banned in your country:(

Look for a stage rental company like: http://www.youtube.com/watch?v=vLMYYWxir_s&feature=youtu...

I want one. I'll commission it like a piece of art.

This reminds me of the awesome lasers in the 80s flick, Real Genius. Awesome!

Impressive as a home build.

They banned colour lasers in Austrailia circa 2000.

At the millennium party Mobile Home they used a commercial laser to project whole Tom and Jerry snippets onto the cliff face of North Bondi.

The ban came in shortly after and we were left with monochrome :(

Aren't all lasers coloured?
