This is a device that informs the user when to stop pouring fluid into a shot glass in order to get the standard ounce and a half shot. To do this, a load cell is used to measure the weight of the liquid going into the shot glass in grams. The first Particle Argon then converts grams to fluid ounces using density. This information is then sent to the second Particle Argon. The second Argon displays this information on a LCD screen. The second Particle Argon then sends a signal back to the first Argon to change the color of the RGB LED light from GREEN (Low) to BLUE (Just Right). The light then changes to RED if the shot is over-poured.
The following YouTube video will demonstrate the product.
As you can see, the device works properly and is very accurate. There are two main things that could improve the product which are; reducing the lag time, and water-proofing. Reducing the lag time could be done by creating a product with only one Argon that controls the circuit, measures, and display the weight. This would reduce the lag time because the data does not have to be sent over the internet. Water-proofing is essential for this product because fluids will be poured all around the electronic components and, if spilled, the device could malfunction. This could be done by enclosing all the electrical components to where only the display screen, the top load cell platform, and the LED light are visible.
This product could be useful for bars as a way to ensure customers that they are getting the amount of liquor that they paid for. It could also be used at home for people who need to measure out fluid when cooking. There are a number of uses for this product; however, the original intention is to assist the user in pouring the perfect shot.
