Present: Bill, Brent, Jim, Doug
Discussion Items:
- Airflow sciences has been given the PO to perform calculations on a 10.5' vehicle. They are working on it now. Results in ~1 week
. - Note sent to Tong Chen of Teledyne describing high-level needs for sampler component to see if they might be interested in collaborating. He forwarded to Mike Metcalf and 'others'.
DWSM
- Doug testing a new bag cap assembly. This led to a lengthy tutorial on the construction of the bag cap and the problems he's seeing with the pressure compensation component. Now we know what the problem is (too much oil in the compensation-side of the system), such that the bag-empty switch is not thrown. Switches always seem fine; it's the hydraulic line that is leaking. Unclear why/how this leakage is occurring.
- Still on track for a first build of DWSM on Monday, April 25.
- Doug has wand designed; parts going into shop soon. Will work with Scott to have complete electrical build of the wand system finished next week for testing.
ESP Drifter
- Brent has been wrestling with his choice of host board. Finally can write files to internal flash, but must turn off lots of bells and whistles, making board much slower. Now will start layering things onto this board.
- Moxa boards work with the x86 but unclear if it works on embedded host. This is next hurdle.
- Will meet with Gene and Doug Monday to discuss Gene's battery tube needs. Might be some issues with the size he needs.
