Intro

• The Midi Glove has the following features
• Allows a user to specify key and scale they wish
  to play in
• Translate your finger positions in space
• Convert these into musical notes played by the
  Z80 trainer

3
Challenges

• Create a glove that sends out signals based on
  finger position
• Understanding and Implementing the UART
• Triangulate position of glove
• Translate X,Y,Z position and finger position into
  MIDI signals.
• Deal with a feedback problem given off by the Z80
• Getting all the parts sent to the right address
• Using third-party hardware (glove, MIDI keyboard,
  ) can create problems more than anticipated

What We Learned

• Integrating hardware is more complicated than it
  may seem especially when a Z80 is involved
• Leave plenty of time for unexpected set backs
• UPS and FedEX have trouble finding Lerner Hall
• Learned Valuable design, debugging, and problem
  solving skills

Conclusion

• Using microprocessors in a project is pretty
  challenging but at the same time important in
  providing flexibility.
• Designing of generic code allowed us for a quick
  and robust integration.
• A more reliable micro trainer would have
  facilitated a smother and less error prone
  integration of our hardware components.
• Thanks to all those who helped out on our
  project.
