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!
