#BarBot
-
Successful mod of the $7 kitchen scale to turn it into a plain load cell that can be wired up to the rest of #barbot
-
The current state of #barbot. Currently struggling with having the pumps all run for a few seconds when it turns on, which is less than ideal. I may need advice from someone who knows more about electronics than me.

Pumps are mounted and wires are laid out ready to solder in place! #barbot
-
Not the cleanest holes I've ever drilled, but I now have all the holes ready to mount the 16 pumps into. #barbot

@wctek Awesome, thanks! This is working out great so far! https://instagram.com/p/9cokcWjcnM/

First successful test of #barbot! Dispensing a precise 0.1 grams of water. It can actually do 0.01 reliably which is about 8 drops.

Decided to try using the #piccolino with a built in OLED display, so now BarBot shows the progress of pouring the shot as well as what's in it! #barbot

Even more progress than I expected today! Now the Arduino is controlling a Darlington array (with LED to simulate a pump.) The 7-segment LED display indicates the progress of the dispensing, showing 0-100 and then

#barbot progress! I now have a scale hooked up to an Arduino taking readings every 100ms, as well as an I2C expander so that I will eventually be able to control 16 pumps

Made an attempt at Secret Aardvark sauce in the crock pot tonight. While it was cooking, did a little soldering to connect header pins to some boards I will be using for #barbot.

Building #barbot... Took apart a cheap kitchen scale for the load sensor. A small ADC to turn that in to useful data. Designs in progress for the top piece. #cocktail #robot #latergram
