The pressure system just didnt work out. Swapping to pumps. I picked all of them up last month and got them cleaned and ready to start using. I had to swap out the quick connects on one side of the valves so now they are regular barbs. I left the quick connects on the spout side since I like that…

2nd Automated Bar Demo w/ Video

Pumps are a No-go

Got those pumps a few weeks ago. Tried to test them out but they just totally fail for my needs. Pump has to be primed with liquid to get it going and then once power is cut off, the liquid drains out of the tubing back in to the bottle. No way I could see to get a consistant flow or measurment…

New Board Designed

I was having issues with the relay board and just started to get horrible trying to fix it so I decided to get it professionally designed and manufactured. I used vworker.com like last time. The guy did a real good job and just made it 8 per board to make it a little modular. Sent it out to a…

Finally working on the bar again

Have had the automatic bar machine on the back burners for the past 4 months. Finally decided to get back into it and wrote the program for Arduino to handle command line requests from a serial connection. While testing that out, found out theres issues with the relay…
