Planning for TiLDA version 2

The TiLDA mk2 project, Code name "ElectroMagnetic Boogaloo", is being headed by Charles, Bob and 'RepRap' Matt

Aim

The main aim of the 2014 badge is to give camp attendees live schedule updates and notifications. As with the original TiLDA we wanted to keep with an Arduino compatible platform that will allow badge hacking during and after the camp. As with previous badge all code and design files are available. Work can be found here on github.com/EMF-TiLDA

Features and Functions

A initial planing session was held during the Newcastle MakerFaire 2013, during which a list of essential features was decide upon along with a big list of shiny, mad ideas that may happen depending on budge and time.
The notes from that session can be found here TiLDA 2/Ideas List

Essential

The following are considers core things that the badge must do for EMF2014

  • Receive and display announcements on talks scheduling
    • user registers their lanyard and which talks/workshops they are interested in on the emf web site
    • lanyard’s registered for talks receives reminders and notice of when and where a talk will be especially important if a talk is moved (time/location)
  • IR interaction
    • could be used for business card mode, allow users to exchange info at push of a bottom
    • games
    • talking to TiLDA or SiNE
  • Torch Mode
    • One of the side effect of the two RGB LED's on TiLDA was they made a great torch
  • Arduino Compatible
  • Work during the event and be useful afterwards
    • Battery voltage measurement and display, Charging management

Nice to have

The following are things that we hope to implement if we have the time and budget.

  • Locations tracking
    • By looking at which gateway the badge is talking to we can get a ruff idea of where on the camp site a badge is located
  • Send text to it, not just talks (SMS you friends badge?)
    • we will have a screen and ability to display text, so sending something to a other set badge should be easy.
  • Use the spearks as a PA system, (download recorded WAV over network then synced playback start)
  • TiLDA ad SiNE reprogramming
    • If we can develop some new firmware to go on SiNE or TiLDA, we might be able to reprogram them from Mk2 by jumping the ISP headers together
  • TTS https://github.com/going-digital/Talkie

Hardware

The following hardware has been included on the badge.

  • Atmel ATSAM3X8A
    • This is the same chip as the Arduino Due and gives us the base platform for the badge

  • Joystick
  • Buttons
  • RGB LED's
  • IR
  • Arduino Headers

Prototype

Design for the badge prototype v0.1 was finished on 4th Jan, files are on GitHub. The aim is to have 2-3 PCB's made for testing and firmware development.


Production

As yet there is no information on the final production board other than we expect to make around 1500 and have them ready at least 1.5 months before the event.
