TOTAL = 1081

Additional cables: NOK 200

ESTIMATED TOTAL OUTPUTS: NOK 11.665

NOTES:

- My plan is to get as many physical inputs installed in the organ as soon as possible, preferably by the summer.
- A decision was made to order 2 midi interfaces and as many sensors as possible from Interface Z for compatibility reasons.
- A single distance sensor will be purchased and tested before ordering more.
- A demo of the airbrush system will be given by GAC the last week in May to determine if the system is appropriate for the needs of this project.
- I need to test how much force it takes to depress the airbrush valves to find out which push solenoid to order.
- Erich suggested that I test the distance sensor during his Making Sense worklab at Atelier Nord (introduction to physical computing) in May, and to attend the Making Sense project-based workshop in June for other development issues.
