Re: Week #15: (4/29-5/3) Progress Reports, Inductive Prox Sensor
A couple of us came in on the off-day, Thusday night to play with Raspberry Pi and get a barcode scanner working. It was interesting to see and learn about what this little compute is and what it is capable of, how it is its own computer with it's own operating system and applications. We cannibaliz...

Re: Week #15: (4/29-5/3) Progress Reports, Inductive Prox Sensor
Today, more good progress was made. Vinnie had installed output relays overnight. Most importantly Rob with Dave's help got the Motion Block working figured out. Now we need to program relative motion and figure out the assigned positions that will be needed for the cup positions. Ricky and Michelle...

Re: Week #15: (4/29-5/3) Progress Reports.
Not sure where my first post went, but here's the second one. This was our second class this week, on April 24. Today, Vinny installed Panduit on the backpanel, which made the wiring look very organized and nice. A front panel was then mounted along with a makeshift belt tensioner that worked well. ...

Re: Week #14: (4/22-26) Progress Reports.
On Monday (extra day of class), Vinnie mounted another strut, pump mountings & pumps, and bolted down the rotary base, not to mention a din rail to hold the PLC on the backboard, and we also mounted the DC stepper driver unit. We met in the backroom to compile a list of all parts we wanted to mo...

Re: Week #13: (4/15-19) Progress Reports
This week, John brought in the 3d printed cup holder and metal fabricated drink dispenser actuator head for the air solenoid. It should work great, although it may need to be stabilized from spinning in place. It seemed that 25 lbs of force was proper for confident actuation. The 4.2A, 24V DC steppe...

Re: Week #12: (4/8-12) Progress Reports.
This week, Vinnie had installed the heavy duty swivel base and cut the 3.5in pipe dies into the top circular plate to hold the bottles steady. He glued the thin belt to the wooden rotor base. We mounted the stepper motor to the back display wall. We also took measurements to ensure the proper center...

Re: Week #11: (4/1-5) Progress Reports
This week, Rick's DC motor arrived along with a mounting bracket. We tested it with the worm/ring gear and found that it presented challenges keeping the gears mated. We experimented with plan A for spinning the rotor by using a belt based solution, but using electrical tape as a proxy. This worked ...

Re: Week #9: (3/18-22) Progress Reports
After lecture, we brainstormed on our system's needed parts and began to spec them out and search for availability on Amazon primarily. We found a 100 rpm DC motor, which we liked in combo with a worm gear/ring. We calculated that the torque and ultimate gear reduction was in our ballpark and the to...

Re: Week #10: (3/25-29) Progress Reports
This week we discussed the status of orders on needed parts, and whether anything could be done to try and expedite them. In the absence of these parts, we rehashed our overall structural and physical setup and placement of major components of the system, where things would go, and modifications tha...

Re: Week #2: (1/28-2/1) Progress Reports
Wed:1/30: Tonight we discussed the pros/cons of various project ideas and decided on the one we wanted. We chose to do the Automated Adult Beverage Dispenser. This option seems to involve or make available many learned concepts such as: -Robotics, Pneumatics/Hydraulics, Temp Regulation, Calculations...
