Hi Brad,

I just sent you an email that  addresses some of those questions.
I can definitely be in EEL 108 tomorrow at 1.

See you then.

Hi folks,

If possible, it would be good for someone from the DSG to drop by
EEL/108 Friday at 1pm to take a look at what has been completed and make
sure we are on the same page here.  Emmanuel and I were planning to meet
at that time already.

There were some prior questions about getting power to the humidity
sensors.  It sounds like that detail was missed and needs to be
addressed as well:
  - What is the expected current draw?
  - Is it feasible to use 3.5V?  We have that available in the detector
    already.
  - Can the power be supplied on the same multi-conductor cables used
    for the thermocouple/humidity sensor readout?
