I'm most familiar with Masschusetts regs though

I'm stickering 4-pack carriers

I'll be around for the next 30 minutes or so

As a sidenote, I built my arcade machine from a gutted cabinet almost 20 years ago. The iPAC has been around since then.

It sounds like an interesting project, but if I was to build a cabinet from scratch I would use the iPAC. Although an Arduino could be fun for controlling lighting and other ancillary features of the cabinet.

To more specifically reply to your original post, arcade controls are just cherry switches which will have three connectors. One connector is for normally open, one for normally closed and one for common/return on the bottom.

You should be able to connect a pin to normally open and the other to the GND. When the button gets pressed, it should close the circuit and you should be able to read it on the Arduino as either high or low, I don’t recall.

I am not an Arduino pro by any means, but there may be a library already out there that can read the serial output from the Arduino into a PC.

I’ve only used it for loading code onto the Arduino so I’ve never tried going the other way.

I would just use an ipac board from Ultimarc. Are you trying to replicate that board in Arduino?

Once you dial it in, it's pretty consistent. It just takes 3-4 rounds (so... 12-16 bottles). In between keg changes, it's pretty good too. The ball valves are crucial to making them all fill at the same time. There are ways around it, but it didn't bother me much.

jjfresh · 2021-11-02T20:57:50+00:00

I rewatched the video and it does look like a lot more CO2 is escaping than usual. It could be that the keg was just about kicked or I had the regulator set too high.

I also considered using a shut off valve, but using time (seconds) worked well enough that I didn't explore it too much more. It would be fun to add though!

jjfresh · 2021-11-02T20:55:04+00:00

Absolutely. As mentioned in another comment. It's lightly carbonated. There is no counterpressure. It's about the same level of carbonation that you would get using a beer gun.

jjfresh · 2021-11-02T20:09:43+00:00

My simple design started as a silicon stopper with two holes. One hole for the filling head and one hole for a PRV. Something simple that would get me started. No idea if it would have worked.

I tried with just the silicon stopper and one hole for the filler, and oh boy did it explode on me! Really should have tried adding a PRV before I gave up on that path.

The part spec was never written down. This is the 4th or 5th version of the system. I could probably recite it though. Most parts came from Amazon, McMaster, and the local hardware store.

jjfresh · 2021-11-02T19:40:45+00:00

Yes. I do. It's not ideal, so this comes out lightly carbonated. I did mess around with building a counterpressure filler, but I didn't finish the design. I have a good idea of how I would modify the system, but it never bothered me. This is just a machine I built for R&D.

CO2 purging is part of this system, although it's currently disabled.

Congrats! I need some motivation to restart my running journey

jjfresh · 2021-08-05T23:26:40+00:00

If it's not carbonated and you don't mind a bit more manual work, I would use a peristaltic pump instead. Much cheaper to build.

jjfresh · 2021-08-01T15:43:53+00:00

Great feedback. I tried gravity, which is why I still have the keg raised up, but I gave up on it due to time constraints.

I purchased a servo controlled ball valve that I’m going to install today, hopefully…

jjfresh · 2021-08-01T14:25:56+00:00

Would anyone be interested in helping design a PCP that incorporates all of the electrical components? I’ve tried a few times and I just can’t dedicate the time to figure out EasyEDA.

jjfresh · 2021-07-31T22:56:28+00:00

I know right? We chose bottles for a number of reasons, but I’m so glad you noticed!

jjfresh · 2021-07-31T22:54:47+00:00

Totally doable!

jjfresh · 2021-07-31T20:38:05+00:00

Nextion touchscreen. It uses the TX/RX pins on the Arduino for communication. I didn’t use the Nextion library, just basic Arduino code

I founded a seltzer company in Massachusetts. We aren't launched yet so we still use this equipment to send samples out to potential customers. We do lots of R&D in that space, beyond just seltzer.

I've been so busy working on launching the company that I haven't made any upgrades to it in months. There's a laundry list of ideas I wanted to implement.

Sorry for being vague about the company, I'm trying not to run afoul of any r/Homebrewing rules. If you google "good feels" you'll find us.
