Why?

To celebrate another fruitful year's end.

Tools

Available

  • Acer P1303 projector
  • speedlink webcamera (needs to get to run under linux)
  • creative webcam
  • T42 laptop
  • red laser pointer mouse
  • transportation means: Martian742's bike trailer

Needed

  • power source (our projector draws 2.3A @ 230V peak and 300W avg.)
  • place for the performance
  • faster computer
  • green laser pointer(s) - User:b42 will borrow a pair from friend

How?

Plan

  • find stuff needed
  • make the speedlink camera to work
  • read the configuration suggestions [1]
  • try different computers and settings

Resources

Conclusion

The peformance failed due to inadequate power supply from the generator (why?).

Lessons learned

  • Obtain more reliable generator, or less reliable one with UPS, next time. Test whether it can power the whole setup for an extended period of time.
  • The bike trailer is great for transporting all the things (+a crate of beer) needed without a car and doubles as a projector stand.
  • USB-powered laser?
  • There was an ambition to rewrite the lasertagging program using OpenCV.
