Holding us up today (Sunday 5th April) is a requirement for an Arduino compatible display. Ideally we need an I2C LCD 2004: http://wiki.sunfounder.cc/index.php?title=I2C_LCD2004
The display is needed by one of our team - Simon, who lives in Berkshire. If anybody has one close by and can lend / give / sell it to Simon then we would be very gratefull.
We also need:
Polycarb, or Acylic 1000x 600 x 10mm makes 1 case to current geometry.
150 x 150 x 20mm acetal for 1 pair of paddles
Fasteners for case, assembly options to be decided
Bag outlet adaptors to enable mask to be remote from bag
PEEP valve Rapid prototype (Ambu design) springs
Potentiometers Linear or otherwise (don't care)
Arduinos/STM32f' development boards
Breakout boards for quick wire wrap development
Case for electronics, Peli case (Size not yet confirmed)
