I have completed the basic "Air production, storage and delivery modules (see attached photo):
- Power supply from an old computer
- Three air tanks: you can shut off two with a valve
- Three double solenoids (one 24 v, two 12 v) to power up to six actuators
- Manual push buttons to actuate each solenoid
- Quick disconnect for additional loads

Update 27 Oct 2013
- I have added a separate power supply for the pump: the "on board" one powers the relays and instrumentation
- Per above suggestions, an pressure switch drives an automotive relay to cycle the pump

To do:
-The "air production module" is now complete. I will put a Lexan screen over the plastic tanks per the above safety discussion.
-I am now working on the "test bench" module. This is where you can quickly lash up different mechanisms and try them out.
- I need some sort of "tinker toy" parts quick to assemble arms, gears, cams, grippers, levers, etc.
- I need to have alternate inputs to allow solenoid actuation from the robot cRIO
- My son (in Electrical Engineering program) is developing a data analysis systemm with pressure and position transducers, force load cells, and a PC-based data recording system so we can quantify performance and compare designs.

If anyone has good ideas or would like to team up, please let me know!
