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…

Demo pour from the Automated Bar

Took a little video of the machine pouring out some drinks to test it out. Check out the videos below.

PCB Finally Etched

After getting more supplies I re-tried doing one test board to actually wire up to a solenoid water valve. There was one flaw in the original design. 2 different voltages that go to the board were going to the same ground(the 5v GND). I scratched away the 12v GND trace and just wired the…

PCB design for Automated Bar

Received the PCB design yesterday and ready for DIY PCB etching! Will get a test board made up in a day or so. Need to get some drill bits and try some laser transfer printing.

Parts on Order

Put everything on order for electronics. Relays, resister, transistors, 
diodes, power supply. Got them mostly off of eBay for super cheap since 
RadioShack bumps up the price a bit.

Testing out PBC fab

Since I got the PCB design I tried to do a toner transfer to etch the board but wasnt having any luck. Couldnt get the transfer to work with an iron using photo paper or magazine sheets. I bought some stuff called Press-n-Peel Blue, its sheets of paper that are used for toner transfer. I also…

Relay Controller Board Complete

Got down to etching the new board. I didnt do the transfer that well so there were spots around the edges with flacky connections so had to use those trace repair pens.

Totally fudged up my relay board

This is what I get for using a DPST(Double-pole single-throw) when all I needed was a SPST(Single-pole single-throw) relay. For the bar machine I set up 3 bottles wired up everything to the relay board and arduino with all the power supplies, even had the arduino…
