  1. Real World / Second Life Joining the Real and the Virtual Jonathan Oxer January 30th, 2008 Linux.Conf.Au 2008 Melbourne, Australia

  2. free your mind

  9. re-imagine reality

  11. Warning: this can kill you!

  12. I accept no responsibility for what you do with the wild ideas I'm about to put in your head ;-)

  14. Choices, choices! Parallel, RS232, PS2, PCI, USB, IR, Bluetooth, ...

  15. the parallel port is good because it's “dumb”

  16. no flow control no comms protocol

  17. just flip bits

  19. the parallel port is bad because it's “dumb”

  20. scripting language support very poor

  21. use a trivial C helper

  23. Introduction to Arduino

  26. Arduino IDE Installation Extract archive for your OS On Debian and derived distros: # aptitude remove brltty # aptitude install libftdi0 \ sun-java5-jre gcc-avr avr-libc # update-alternatives --config java (select java-1.5.0-sun)

  27. Introduction to Linden Scripting Language

  28. State machine

  29. states and triggers (or “events”)

  30. LSL Building Blocks

  31. HTTP out of Second Life

  32. XML-RPC into Second Life

  34. Email into Second Life

  35. Modified SL client

  36. Custom SL client using libsecondlife

  37. Private SL sim

  38. Introduction to Electronics

  39. Voltage, Current, and Resistance

  40. Voltage (Volts, V) is like pressure

  41. Current (Amps, A) is like flow rate

  42. Resistance (Ohms, R) is like... well, resistance

  43. Ohm's Law: V = I x R I = V / R R = V / I

  44. Ohm's Law: V = I x R I = V / R R = V / I

  45. Ohm's Law: V = I x R I = V / R R = V / I

  46. Breadboard

  47. Breadboard

  48. Resistor

  49. Transistor

  51. Diode

  52. LED

  53. LED

  54. Capacitor

  55. Switch

  56. Hardware Building Blocks

  57. Transistor / Relay

  59. free your mind

  60. hardware is malleable

  61. use scripts as glue

  62. More information More Information Skeleton site now up at: www.secondlifeintegration.com Join the Second Life group: “Second Life Integration” These slides are at: jon.oxer.com.au/talks Thanks for listening :-) Making Things Move Jonathan Oxer

  63. Ohm sweet ohm

  64. Not just a pretty face
