Would just require HAL c code for access to peripherals<br /> **Would allow users to run their own code on the badge without any additional software on their PCs. micropython appears as mass storage or via a terminal on USB<br /> *have SD card support for additional user storage<br /> <br /> == User Interface (Screen Options) ==<br /> *'low res' black &amp; white LCD (as 2014)<br /> **can be seen during the day without a backlight<br /> **backlight needed at night (~10mA)<br /> **good outside contrast<br /> *'high res' colour TFT LCD<br /> **higher resolution and colour adds to experience<br /> **backlight needed all the time (can be dimmed in low light)<br /> **contrast is poor in daylight<br /> **cost about the same as the mono LCD<br /> **'transflective' modules with improved daylight contrast available, but likely increased cost<br /> <br /> <br /> == Wireless Network ==<br /> *Downloading camp info<br /> *Can be used to obtain badge location based on RSSI<br /> *send messages to friends<br /> *ask for friends location<br /> *sensor network<br /> **combine with location to map temperatures and so on over the weekend<br /> *potential parts - MRF89XA (3mA rx current, 868MHz, 10mW)<br /> <br /> <br /> == Other peripherals ==<br /> *IR for sharing between badges<br /> **can share python/LUA scripts, contact details<br /> **used to 'friend people' to share messages via the radio<br /> *accelerometer to go into low power mode when put down<br /> **eg MMA8652 (40p)<br /> <br /> <br /> == Power supply ==<br /> *ideally would last the weekend (60 hours)<br /> *single AA<br /> **standard alkaline - 2.5Whr (~15mA average at 3.3V)<br /> **lithium AA - 4.5Whr (~25mA average at 3.3V)<br /> *lipo<br /> **2014 lipo ~4Whr<br /> **requires charging circuitry<br /> **ideally wants a hard back to prevent damage<br /> **increased cost<br /> <br /> == Hackability ==<br /> *conductive thread pads next to lanyard<br /> **supply little bags of LEDs and thread for say £2<br /> *extra GPIO broken out<br /> **ardiuno footprint?<br /> *python/LUA would allow for beginners to hack the badge</div>
