Project Development

Complete your final project, tracking your progress:

what tasks have been completed, and what tasks remain?

• Simulation was tested successfully, even with real serial ports. 
• Electronics are working right now, tests were successful.
• The design of the module is completed.
• The MDF module was cut perfectly.
• The cables and sensors were correctly mounted on the MDF module.
• Software was tested correctly.

All tasks were completed correctly.

what's working? what's not?

Regarding the activities developed that were relatively simple, they were: the design of the laser support module (AutoCAD) and the cutting of MDF (press fit technique). One of the most complicated stages was the assembly of the electronic components in the MDF module, due to the little space to place the wiring. The testing of the program code also took me a while to perfect (trial and error).

Additionally, the most complicated issue in itself were the final tests since a completely dark space with the presence of smoke is required to be able to appreciate the presence of the laser rays between the emitter and receiver.

what questions need to be resolved?

It's important to know the electrical comsumption of the instrument. Because in the future it can use batteries for standalone use.

what will happen when?

The design will be upgraded to use 3.7 V lithium batteries. (maybe a second version)

what have you learned?

I've learned about MIDI signals, protocols and design. It's possible to build whatever kind of instrument using digital fabrication with MIDI protocol.

The easiest and cheapest to design an instrument with no limitation.
