Operating Millifluidics
Always use less than 10 psi inputs into the millifluidics and pressure regulator to avoid breaking them
Never use ethanol to sterilize millifluidics as it breaks them. Use bleach to sterilize and flush it with sterile water.
Plug in 5V power supply and 5V fan
Changing Pressure Settings
Option 1: Manually change via Arduino (hard coded)
Follow the Arduino Software Installation
Unplug the SAMD21 from the pressure regulator before uploading code (otherwise there might not be enough power to the SAMD21 from the USB)
Upload modified pressure code to SAMD21
Option 2: Add a 'pres' command to the evolver conf.yml and modify conf.yml
Connect a 8-10 psi air input into the input port (only port on its own in 1.0 design)
Connect regulated line to both sensor (below) and controlled output (white, above) as shown below:
Set Up Solenoid Control
Solenoid Bank Diagram (facing holes)
The solenoids should be normally open and connected to the 8 psi air source. ie Vacuum when closed
Connect solenoid ribbon cable to slot 5 on the fluidics box
Turn on eVOLVER server and fluidics box
Check that the solenoid bank is correctly set
Run ipp_cal.py on the server:
Use command:
python3 ipp_cal.py <frequency (hz)> <seconds to run>
Hook IPPs up to a pressurized input bottle for consistency
Make sure that IPPs are operating as expected and producing the expected flow rate
