Overview of Status of Analysis, Design, Fabrication, Tests, etc.
Determining space constraints, parts locations, and ways to make parts easy to get (Amazon) and minimal machining (3D printing, lasercutting, bandsaw, drill, tap)
Considering different options for heating reservoir
Accomplishments from Previous Week
Determined volume constraint for full assembly, and made CAD drawings to allocate adequate space for each part. Will probably need a 2nd pump. (Sebastian)
Prototyped a brewing module canister from easy source-able parts (fittings, drill, tap) that is theoretically easily cleanable and modular. (Sebastian)
Eliminated several options for heating components (Phil)
Selected a relay and wrote code for Arduino control, and built test system using an LED and potentiometer (Phil)
CAD of the system (Alec)
Goals for Next Week (list names after each item). Use specific and measurable objectives.
Determine how to cut the coffee grinder plastic casing and mount it to the rest of the assembly to allow for coffee-ground gravity-feed (Sebastian)
Assemble basic on / off control of heater using Arduino and relay (Phil)
Finalize design concept of heating reservoir (Phil)
Next prototype of brewing module (Alec)
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
If it takes around 7 mins to heat up the water, then it's good
instead of 1.6L, they want 1L now
In the future, instead of using a kettle, think about designing our own water heating reservoir
Try to come up with a way of getting gravity to feed the water (AKA, design your own reservoir)
Design PI controller and heating system on our own, use inexpensive components if possible
On / off heating control is fine for preliminary designs

Write name after bullets
Think about water stratification when it heats up
is 15'' inches between countertop and cabinet an actual standard? No, it's 18'' (from here)
