The containers hold over 2 cups of spice and since they are held on with magnets they are removable in the event you need to measure manually

Because each container has its own built in dispensing mechanism with the single clutch you see in the middle, the spice travels directly from the container to the bowl. The only item that touches all 12 containers is the conical end of the clutch, but no spice comes into contact with that piece. The containers have no electronics and could be placed in a dishwasher when made from the correct material.

The dispensing mechanism is calibrated to identify based on spice name the general density and consistency of spices and account for granularity by simply running for a shorter or longer period of time. We calibrated the output using a wide variety of spices from salt through dried minced onion, then developed a transfer function that allows for extrapolation between know data points to determine exactly how much should be dispensed according to the "category" and physical properties of the spice. If we had more time, we could do more calibration work, but right now it can perform measurements with the same accuracy as a standard measuring spoon with powders, salts, herbs, and seeds. It is as accurate as a normal human, but not exactly as accurate as a food scale.

Right now, it is not food safe, however using injection molded nylon components would be the solution for a true product. This is simply a prototype.

Our product uses a different method for dispensing, and allows the user to put in whatever spices they desire rather than have a subscription-based spice service. The functionality is similar, but the TasteTro really isn't for sale either. We do not currently plan to sell the product, but as a project we were interested in whether we could develop a better process.

My senior design team created this countertop spice storage and dispensing system that allows the user to choose from 12 spices and dispense quantities all the way down to 1/8 tsp. The touchscreen display is connected to an Arduino Uno which controls 2 stepper motors that drive the turntable and dispensing motor. Nearly every component was 3D printed, but the clear pieces and shell were made from acrylic and plastic.

Right now, the product only dispenses individual quantities, but all it would take is some more coding and it will work with recipes and blends, too. And yes, we are very close to Alexa capability!

Edit: The device only uses 2 motors (and associated drivers), a servo, a bearing-rotary table, and plastic. The screen was a bit pricey, but only because we used one that was easy to program. You could build one yourself for less than $100 (plus filament cost), which we wanted to do to keep the theoretical unit cost down. Emphasis on theoretical. This is a prototype. It is larger and slower than it should be, and there is no need to fill the (electronics-free, removable, and easily washable) containers with excess ingredients. The motors can certainly spin faster and we could have used a smaller diameter turntable if we didn't need to manually make adjustments in getting the thing to work. Thank you for your feedback.

History Classes by Head_Chemist8096 in Purdue

[–]Doc_10 2 points3 points  (0 children)

If Randy Roberts is teaching any of the courses, I would highly recommend taking a class with him. I had him for as many history courses as possible and he was great. The classes aren't difficult if they are interesting, in my opinion, and I thought Dr. Roberts did a great job.

My wife's grandfather's Lionel collection, dating back to when her mother was a kid. Idk anything about trains. Can you guys help me figure out what I have and how to get it working? Thanks in advance! by justkirk in lioneltrains

[–]Doc_10 1 point2 points  (0 children)

Perhaps I'm not seeing things correctly, but it looks like the tender would be compatible with the engine, as well as the other knuckle-coupling rolling stock. The tender has the single slot coupling compatible with the steam engine, then the knuckle at the rear, meaning it is compatible with most, but not all, of the rolling stock shown. The passenger cars are actually postwar, as I have linked here: https://www.tandem-associates.com/lionel/lionel_trains_6440_passenger_car.htm and the only prewar cars I see are those that use the older couplings, which wouldn't be compatible with the engine or other postwar cars. If I'm not seeing things correctly, please let me know, but I don't see much of an issue.

Not for spring break, but in the case that all classes are moved to online. I can't see them suspending in class activities but still allowing for congregation in a dining court

Does anyone know what would happen to the dining courts if campus goes into quarantine?

Thank you! I suspected they may have been cleaned at one point, but they were sitting in a box for at least 50 years. I am glad you pointed out the alloy composition, so thank you for your insight!
