TiLDA MKe/Ideas List

"ElectroMagnetic Boogaloo" TiLDA mk2

Notes from the initial meeting held during Makerfaire April 28th 2013

Numbers and Timeline

• Look at around 1500 site licence for EMF2014, so at least that many landyards
  • look to build at least 10-25% excess
  • also need to know numbers for weekend tickets vs day tickets and if day tickets are also getting a lanyard
    • day tickets didn't not get a TiLDA in 2012
    • suggested that day ticket holder could purchase one as discount say £10 on top of their ticket price, vs posible selling any spares at say £40
• Looking to budget about £30 each
• They must be built at least 1.5 month before the event, NO last minute rush again
• Also includes firmware and software to be ready one month ahead of time,
  • possible in final testing phase
  • three main parts to consider
    • firmware for lanyard
    • colocated gateways
    • web/server side (local at camp and hosted online)
• Looking to have early prototypes (breadboards) within a few months, working prototypes by end of the year, small run of 50-100 for developers

Things it must do

• Receive broadcast announcements on talks scheduling
  • user registers their lanyard and which talks/workshops they are interested in on 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
  • games
  • talking to TiLDA or SiNE
• Torch Mode
• Arduino Compatible
• Work during the event and be useful afterwards

Hardware that's required to support the above

• Arduino Compatible
  • Looking for 32bit Cortex M3
  • Due chip Atmel SAM3X8E
  • Keep the Arduino 1.0 (R3) style headers (moving them to the back as the screen will take up most of the front)
• LCD Screen
  • Graphical
  • Black and white (colour is likely to be to much power)
  • Fill a large area of the front side ( 50x80mmm )
  • Low power (if only we could get e-ink or sharp memory)
• Speaker or at least a buzzer to help notify users of update
  • Buzzer is lowest option
  • SAM3 can to sound playback thanks to the DAC's. Arduino has support for playback of WAV files
• Broadcast receive, this means a radio
  • Wifi is too expensive and needs to much power
  • First choice is Ciseco SRF module (868MHz, same chip as IM-Me)
  • BLE/BLE emulation would be nice, but would require 2.4GHz radio
• LiPo battery
  • Same as TiLDA? 1500mAh single cell
  • needs charge hardware from usb/dc point
  • need to be able to run the badge from USB without the battery plugged in
  • On/Off Switch (slide)
• Torch Mode LED’s
  • High bright white or same RGB as last time
  • RGB means can have other uses as well
  • Torch mode button/slide switch
  • Firmware can do touch sleep modes (turn off after X minutes)
• PCB’s
  • Same style as TiLDA
  • As close to same size as possible, but depends on screen and moving of the Arduino headers
• Input methods
  • Buttons
  • joystick
  • Blackberry trackball
  • Capacitive touch
• Landyard’s to hang it off
  • Printed with EMF branding
  • Snap release at the back
• IR
  • Lessons learnt from TiLDA and SiNE IR??
• Sponsors Logo’s
  • Need to leave room for these some where

Things we would like

• Real time clock
• µSD socket (footprint at least, if not socket and card)
• Use the spearks as a PA system, (download recorded WAV over network then synced playback start)
• Unique ID for each badge possible MAC address or even IPv6
• Locations tracking
• Send text to it, not just talks (SMS you friends badge?)
• Twitter client?
• Battery voltage measurement and display
• Lilypad Landings so it can be turned into a wearable
• Tiny robot shields (motors/wheels/sensors) that it can plug into
• Custom Glass LCD http://www.alibaba.com/product-gs/614004757/customized_TN_positive_graphic_lcd_panel.html
• TV-B-Gone code
• Lego Holes
• Cake (is not a lie)
• Limited editing for staff/volunteers (different color PCB’s)

Crazy Ideas that we might add if theres any budget left

• IMU
  • Accel
  • Gyro
  • Compass
  • Barometer
• Inductive charging
• Microphone
• LDR
• Temp
• Humidity
• GPS
• GPRS
• TAOS TSL230R Light wave sensor
• Servo Headers
• Capacitive Touch Pads
• Laser cut case (might be used to help mount the LCD)
• FPGA Chip
• Brain Monitor
• Mini Led matrix square 8x8 20mm square
• Pulse sensor
• Fingerprint Scanner
• Barcode scanner
• Bluetooth LE

Crazy Ideas have been dismissed for random reasons

• Taser mode (NO)
• Laser (NO)
• NFC (to expensive and power hungry)
• WIFI (to expensive and power hungry)

• Camera (to expensive and power hungry)
