I semi got a kick in the butt when I found out that Nick Pegg (twitter: nickpegg) at Missouri University of Science and Technology was building a bartender as well. Looks like we’ll be doing a little challenge for who’s is better designed from hardware to software. From the video, sounds like his runs on pumps, mine is pressure based.
His bartender prototype:
My bartender prototype:
Due to this challenge, I’ve decided it was in my best interest to order some more parts to get this puppy built 100% again. So I ordered 3 more valves from McMaster Carr (part # 5489T633) (Polycarbonate Solenoid Valve W/ Tube Conn EPR Seat, for 1/4" Tube OD, 80 Max PSI, 24 VDC) so now I’ll have 10 food grade valves and I also ordered more stoppers and connectors from US Plastics and Home Science Tools. I’m seeing if I can’t come up with a better way of doing the liquid containers also. I bought some test parts for testing out a new way of doing this.
