I've got a bad case of loving you

They didn't have pink acrylic so I decided to join two kinds of acrylic together to make pink. Can also etch in to the pink with a design! Tried to do that myself but am going to get my friend Daif to do it.

Trying to figure out where the knobs and the lasers will go and all the internal circuitry.

I think in this photo we were trying to figure out if the laser should go flush against the laser or sit in a bit ha.

The first white heart has been cut! I need to figure out how I am going to join the hearts together so I haven't cut the pink parts yet. Maybe it could be joined with metal? That would look cool. Also thought about doing a living hinge out of plastic but it might not work. Could snap easily.

Daif is a genius and this is his design for me.

Needed to make some knobs for controlling parts of the harp.

At first we thought we needed three knobs in total. One for scale, one for transposing and one for performance.

The two Crystal Gems are for the scale and transposing as they don't need to be used during a performance. I decided to make the performance knob quite large and so that it would fit in my hand and be easy to see and use during a performance.

The test knobs turned out quiet well! 

We have decided to add an extra flat knob so that we can also control the reaction to ambient light. 

 

Now just need to decide which colour to print the knobs!

What do I know? Flashinlights, lights

The diode's arrived!

The diode's arrived!

Nicolas putting together a trial of the circuit. Used AA Batteries to power LED + transistor. Needed a multimeter to test voltage output by the diode amplified by the transistor. We were aiming to get a big jump in the number on the multimeter when we cut the beam between the LED and the Diode. At first when we cut the light between the LED and the diode there was only a small difference, so Nicolas added in a transistor to amplify and the difference between that and when the beam was broken was much greater.

He also put a casing around the diode to protect it from ambient light. He just used heat shrink tubing cause it was the right size. We will have to 3d print some casing for it so that it is somewhat protected from the ambient light. We will also have to design the casing so that when it is stuck on to the heart the laser can be adjusted to line up with the diode when needed. Will probably do a screw and socket design.

To do an extra test, Nicolas put in an LED in the bread board to test the circuit. The LED turned on and off when the light was blocked between the laser diode and the other diode in the casing. SUCCESS!

"I think I need a new heart"

Building the casing for my laser harp!

Designing the heart in Illustrator + also sketching where I think the performance knobs could go.

Cardboard test of what the heart could look like, and where lasers could go.

I wanted the heart to be big as I want it to look good on stage. I made the proportions to fit my body so it's about 80cm wide so I can easily trigger the lasers. The width of the heart border also needed to be able to fit an arduino, the lasers and the other electronics. 

BZZZZT LASER CUTTING!

BZZZZT LASER CUTTING!

Cutting out the heart in two parts as the wood we had wasn't big enough to cut the whole heart in one piece. Thought about reducing the height of the heart but talked with Nicholas and he said keep it big! Need to think about how to join it. This heart was tweaked a wee bit from the cardboard heart.

The trial cut in wood. Happy with the shape so now figure out where to put the knobs!

Instant Fantasy Lazer Harp

Creative Concept

I make music under the name Instant Fantasy and as part of my live show I would like to create a lazer harp in the FabLab. I use projections and vocals for my performance, and have explored other types of elements for the show (Wavelength app) but I would like to add another performative element to my live show that is both audio and visual.

The lazer harp would initially be used to control a keyboard through a midi controller, but could also be used to trigger visual elements of the performance.
