Laser Harp
Prototypes
The beginning of this project was a lot of "proof of concept" work. Here is a line of photoresistors being tested for digital-switch compatibility.
Getting it dialed in.
choosing the correct resistors to work in a wide range of light scenarios.
Models and Sawdust
In the Thingspace I started to see about what dimensions would be best for the harp body.
Mocking up
I needed to see how accurate and adjustable the lasers would be when I mounted them like this. 7-8 inches is the sweet-spot.
Options
I had to see if a tight fit recessed hole was better than a larger opening that offered more adjustability.
Beam Length
I was checking ergonomics and playability here.
On/Off
I wanted to be able to control notes being played so I ordered a set of switched that will turn lasers on-off depending on if the player needs that note.
Visual Aesthetics
For installation and viewer interest I wanted to see how visible the beam could get under different circumstances.
