Yes. hm. that would work.

For 3-phase you should also add a 60 and 120 degree delay for L2 and L3..

Yes. Arduino.

The valve interference problem is solved. So, now I'll run another batch to test.
Also I ordered those aquarium rings. It'll be interesting to see how it runs. From what I read partial flooding/semi aquatic is best for them too.

void reset_i2c() { Wire.end(); digitalWrite(I2C_POWER_PIN, HIGH); delay(500); digitalWrite(I2C_POWER_PIN, LOW); delay(300); TWCR = 0; Wire.begin(); //YYY lcd.init(); lcd.backlight(); lcd.clear(); PCF.begin(); // for the raster keypad } void check_i2c() { static long lasttime = millis(); if (Wire.ge...

With this I think you won't need even need a constant feed rate, the system will stabilize itself regardless.

I need to make a separate GIT-project on gitlab for this one and make it public readable, that would probably ease things :-) i2c is pretty straight forward. But if it locks up, it's a pain. Arduino has recently included a timeout, so at least now you know when it's locked. The mistake I made was se...

image.jpg Great project and thanks for sharing zukram. It is always nice to see projects get off breadboard's and end up in boxes. Yes please share code . Also a quick schematic would be nice too . I’ve been working on a Burstfire controller rather than the time proportional you have used , so I am...

IMG_0096.jpeg No, not really. Its a combination of the "condenser control liquid management" someone here posted a long time ago, and an E-Arc LM control system. By moving the condenser in the head I can control output like if I had a needle valve, and the valve closes on temperature. But...

I've ran it one more spirit run now and I must say that it works very very well. I ran it at a lower pressure this time for the entire run. One thing I noticed was that the E-arc LM worked better than I've experienced before. It might be due to the power management regulating down sligthly as the va...

Ok

And why is nobody talking about CCLM? It works really nice for me. Easy to control and easy to add an E-arc-system to it. 0-100% reflux, no expensive parts. (unless you want to control it with electronics). Only difference from CCVM i that you need an almost 90 degree turn on top so you have a tilte...

Aw. well. yes I joined to share my invention of using pressure to regulate power. I've learned so much from others, so I wanted to give some back.

Still waiting for the mash to clear up.. sigh.. I hate waiting for mash...

I completely understand wanting to try things and experiment. I question your claims. A good column is ultimately limited by the math of energy. If you doubled your output by running it flooded you didn't have a good column to begin with. Ultimately you did indeed figure out how to maximize boiler ...

I'm interested in the pressure sensor used, do you have a link for it? https://www.aliexpress.com/item/1005005970071367.html?spm=a2g0o.productlist.main.47.66418dbL8dbLel&algo_pvid=11185b4e-9d5e-46d3-b023-ecec5b19a155&algo_exp_id=11185b4e-9d5e-46d3-b023-ecec5b19a155-23&pdp_npi=4%40dis%21...

At any point during your run is the PID turning off the power to your heat source? Even for a split second? Or does it continuously modulate with no interruption of input what so ever? The thing is that within the context of what we do heat always = pressure. Though pressure doesn't always = heat. ...

Old thread, but you can check out this:

About controlling the flooding level.

No thanks , not even a bit interested , I cant see the point of complicating what is already a very simple process. The point: Double production rate, slightly higher ABV. And besides, when the PID is tuned in running is very easy, I'd say easier than just running E-arc or manual. Another point of ...

If anyone want's to try this, I can provide a schematic and code.. If you can stand swedish comments :-) This setup is good for 16 A. Also 9kW is hardcoded.. Easy to change though. It has 3 modes, manual power control. Temperature PID control. Pressure PID control. It should work fine for 60Hz. And ...

It looks like this

35 inches of scrubbies? That isn't enough. 36 inches of 12 mm marbles is enough. Diameter: 3,5" 89 mm Lenght: 60" 1500mm I've never considered running with marbles. I've considered SPP, bubble plates and sieve plates. Or just perforated plates, but I don't fancy drilling that many holes a...

I also have a temp alarm, the pot temp is a good way of indicating that the run is over, so I plan to let the controller shut down when reached a certain temperature. I think that'll have to wait until the PT1000's are in place though. That's not important. The idea I wanted to share was the possibi...

If I was going to use electronic control on my reflux column it would be based on boiler pressure. From experience, I know somewhere between 4"and 6" of WC is the sweetspot. Having said that, automation has no sense of smell nor taste. :lol: :-) It's the person programming the automation,...

What percentage is your wash before and after a run? If you are starting 10 percent and running down to say 3 percent there is a significant difference in water to alcohol percentage. Due to the difference in latent heat of vaporization as you run the energy required to boil the water becomes more ...

I'm not controlling by temperature, I'm controlling by pressure. That's the whole point :-) Maintaining an even pressure in the pot also maintains a level of flooding (within say an inch). The reason for trying this was that running semi flooded seems to have some benefits (which it does) and by usi...

I could'nt find anything about this, so I think a thread about it migt be in order. I've read a lot about semi flooded state, so I decided to try it. As many others I realized that it was a bugger to keep running stable. I figured that the pressure in the pot should be proportional to the liquid pil...

Hello. I started moonshinging back in the 90's, but then had a stop for about 15 years, and took it up again a couple of years ago. Since 'the last time' I've gained some experience in tig-welding and also electronic construction and programming, which had made the hobby so much more intereriting. M...
