[...] When is a harp cooler than a guitar? When it’s a friggin’ laser harp. According to creator Stephen Hobley, a call of lasers expands out of a bottom unit, and users retard a light to emanate MIDI synthesizer-created music. Sliding your palm adult and down even changes a tone. Check it out. [...]

Dude, that’s amazing. I’m starting to think about where to put them already haha. That’s really good and would be cool pretty much anywhere!

Thanks for the inspiration!

Hello.

How can i do to get the filles for build a laser Harp? What is the price?

I read your paper on Makezine for the laser Harp
The sensors GP2D12 are obselete or very difficult to find.
Can we change it with a GP2YOA21YKOF? and if it’s possible where can we found the output conversion for this sensor?

Regards.

I know that with the 5mw green/red lasers I use, the I get a response time of about 60+ times per second, using a framed design, with optic sensors. In the reflected unframed design, the reaction time may be a bit slower, though I am about to get a ProLight Laser Harp controller, to test it out. I will also see if the ProLight will work with my OptiMus software. And if it will interface with the OptiMusic midi controller, which will register the voltage produced , and trigger accordingly, with a pitch or volume shift, according to where your hand is in the beam. Stephen, have you had a chance to try out the ProLight or Kroma controllers yet? It might be interesting to have you try them out, and do a kinda Laser controller consumers report !!:–) A question for you, you sold your plans,… do you know if the entity who bought them is coming out with a production model ??

If you are trying to use a regular video camera then you will run into latency issues – my original design using a photodetector array synced to the laser projector output (ILDA) – there were never latency issues, once the system was calibrated for the venue.

Hey,
I’m not sure if this is active or not anymore, but I kinda want to build a laser harp. The biggest issue stopping me even THINKING about it is latency. Seems like that’s the main reason you always see videos of people using them strictly for pad and such rather than instruments with quick attacks. Anyways, any idea what the latency on them are?

Thanks,
Alexey.
