Progress Continues: Microcontroller and GPS Purchased

Arduino Diecimilia

Why?

• Has a serial input


• Multiple Analog input/output controls


• Very cheap (~$30)


• Familiar programming language


• Large user help base

After buying this, I realzied I need a GPS first and foremost:

ETEK EB-85A

Why?

• Cheap (~$55) seeing a pattern here?


• 5 Hz refresh rate (say wah!?, most are 1Hz, or even 1/2Hz)


• Serial NMEA output

Anyone know where I can get cheap, accurate pressure sensors?
