1 Reviewed Specs for Photo Diode,
Learn to use Keil PK51 Package
Looked at Current to voltage Converter
2 Set up simulation for I to V converter Learn to use Keil PK51 Package
3 Finished simulations for both I to
Begin coding weapon software
V converters and started building circuits
4 Finish building circuits and test them Interface weapon software and
laser systems
Conclusion
 Software
- Working on weapon software
 Hardware - Working on laser receiver
for the weapon
 Many challenges to overcome to finish
weapon
 A little behind schedule
