1. Big projects using Arduinos Aka Guerrilla Tag using Arduino Created By George Patterson 30 May 2012

2. Breaking down your Project a) Break down the project into smaller pieces such as buttons, LCD, RF Modules etc b) Devices using serial ports should use pin 0 and 1 c) If you have devices that are timing sensitive such as triggers or rotary encoders, pencil those in next on interrupt pins d) Next are the bus devices such as i 2 c and SPI, if used e)Finally position the rest, such as LCDs and LEDs.

3. Laser Skirmish Think of it as paintball skimish No pain, paint and mess Longer range -More realistic What is a tagger?

4. Arduino Easy level of entry Large community Totally open source (almost)

5. Guerilla Tag Inspired by Open Source End-to-End-to-Server Developing with the help of CCHS Contains multiple sub-systems Infra-Red Emitter Infra-Red Sensor Focusing Lens Sound Generator Radio module

6. Sub-systems: Infra-Red Emitter DIY and even commerical laser tag is not using Laser Simliar technology as a TV remote. An emitter is simly an Light Emitting Diode (LED for short) Focused using a Lens for longer range and accuracy Driven from hardware driven PWM.

7. Sub-systems: Infra-Red Sensor Detects the IR signal from a tagger or other device while suppressing interference Deceivingly simple but contains a IC to pre- process and shape the signal into a digital signal.

8. Sub-systems: Focusing Lens Require double convex or bi-convex lens to that match the LED Plastic or glass is okay.. no iron though.

9. Sub-systems: Sound Generator Arduino can generate beeps and pew-pews – Doesn't sound good. Using an sound recording chip using a ISD17xxx Build your own – Not simple

10. Sub-systems: Radio Module In order to communicate with the server and other taggers, you will need a RF module Find something that works Digi Zigbee modules work well but are not open There can be only one Coordinator on the same PAN SeeedStudio RFBee is open but very low level.

11. Simplified Protocol (General) Player shoots and hits a target Target makes a sound Hit and rounds fired are recorded for score purposes

12. Simplified Protocol (Large field) Similar as the general scenario just covered At long range you can't hear the target when they are hit Instead use RF to send a radio packet back to player saying that the target was hit

13. Simplified Protcol (Server) Once an RF transmission is available, it can be widely utilised by adding a simple server Configuring all taggers and targets for a game type. Players can be assigned to teams via the server Server tally statistics in real time for specators Your suggestions

14. Don't be an idiot! Don't use infrared lasers in Laser Tag Do not create a tagger that looks too realistic, Sci-Fi taggers are fun! Don't spook the mainstream Do not hold a game in public parks Get permission and have a ball on private property. Game one

15. Future Project Design a Remotely controlled vehicle Repurpose a childs ride-on electric car – cheap platform. Requires two cameras and a gimbal mounted tagger. Operator(s) sit at a console of some sort. Accessible for Inclusion

16. Next Challenge Currently working on the Infra-red protocol Following that I will be working on the Optics Adding RF comms Attending with proof of concept at BarCamp Melbourne? Discussion: Web based graphing software

17. Summary Paintball without the pain(t) and mess A lot of work if building from scratch-Initially repurpose if possible Get the protocols right and build on the foundations
