Research Development of microcontroller based systems for science Several projects involve the use of microcontroller systems to design new instrumentation and sampling devices. The systems are based on the open source Arduino microcontroller and the popular BASIC Stamp modules from Parallax. 
Breadboard development for keypad input to underwater sampling system
   
Nautilus - an autonomous reactive underwater sampling system.
Collecting samples from remote areas or over extended periods of time require specialized equipment. Much of this equipment is not commercially available so we need to design, build, and test this equipment. Early schematics and plans of NAUTILUS - an autonomous underwater sampling system
Keypad input to enter methods and record volumes filtered
Pumps and solenoid valves to control filtering system
MOSFETs to control solenoids
